Proximal humeral fractures: association between displacement and fatty degeneration of the supraspinatus muscle.

INTRODUCTION: To evaluate the relationship between initial displacement in proximal humeral fractures and fatty degeneration of the rotator cuff measured by CT according to the Goutallier classification. MATERIAL AND METHODS: This cross-sectional observational study evaluated patients with proximal humeral fractures over a six-month period. The study included patients ≥ 18 years old with complete radiological views (anteroposterior, lateral, and Grashey) and a CT scan of the affected shoulder; previous fracture or ipsilateral shoulder surgery were excluded. Neer's classification system and Goutallier stages were used to evaluate the patients. Demographic data were collected and, two groups were analysed according to age (≤ 50 years and > 50 years). RESULTS: Sixty-two patients were included (m = 36, f = 26, ratio 1.3:1); seven patients were excluded. Male patients (36, 58.1%), patients older than 50 years (33, 53.2%) and a low-energy injury mechanism (36, 58.1%) were the most frequent cases. According to the Neer system, the most common proximal humerus fracture was fracture-dislocation in 17 (27.4%) cases. The most common stage in Goutallier's classification was I (some fatty streaks) in 22 (35.4%) cases. Younger patients (≤ 50 years) had more displaced fractures with low fatty degeneration (p = < 0.001) than older patients (> 50 years), who had minimally displaced fractures with greater fatty degeneration (p = 0.567). CONCLUSIONS: High-energy mechanisms are associated with younger patients and a more displaced fracture according to the Neer classification. Older patients had a more advanced Goutallier stage and lesser displaced fracture. We should consider a more aggressive approach in the treatment of non-displaced fractures in elderly patients, less conservative and more surgical management, to obtain a better clinical evolution after the treatment of these kinds of fractures. LEVEL OF EVIDENCE: IV.

Modified-tension band suturing: 'the pulling the reins technique' - a technique for displaced proximal humeral fracture with medial column instability.

Fractures of the proximal humerus with medial column instability are challenging and present an unacceptable rate of complications and reoperations. Despite good results reported with the use of locking plates and augmentation techniques using bone graft or a second plate, varus subsidence and fixation failure have been frequently reported. We describe the case of a patient presenting with a complex, multifragmentary proximal humerus fractures successfully treated with open anatomic reduction and internal fixation using a locking plate augmented with lateral traction using three bone anchors in the humerus head. After 18 months, the patient reported fully recovering the mobility and functionality of the operated shoulder. The use of bone anchors pulling the humeral in three different directions like three vectors applied from medial to lateral, posterior to anterior and lateral to anterior help to reduce the most important deformities (varus and retroversion) by applying the tension band principle. This is an interesting approach to avoid primary and secondary reduction loss of the proximal fractures of the humerus with postero-medial cortical defect. The procedure is a good alternative to be used in patients with failure or insufficiency of the medial wall and marked varus.

Fracturas de la extremidad proximal de húmero en tres y cuatro fragmentos en el anciano: ¿Tratamiento conservador o artroplastia reversa? / Fractures of the humeral proximal extremity in three and four fragments in the elderly patient: conservative treatment or reverse arthroplasty?

OBJETIVO Comparar los resultados funcionales obtenidos en dos cohortes de pacientes ancianos tratados de forma quirúrgica (artroplastia reversa de hombro) versus tratamiento conservador. MATERIAL Y METODOS Estudio ambispectivo, no aleatorizado. Se incluyeron pacientes de 75 años o más, 15 tratados de forma quirúrgica y 16 siguieron tratamiento conservador. Seguimiento mínimo de 12 meses. A los 3, 6 y 12 meses de la fractura evaluamos las escalas ASES, Constant-Murley and Disabilities of the Arm, Shoulder and Hand score (DASH) y EVA. Además evaluamos los resultados radiológicos y las complicaciones. RESULTADOS No encontramos diferencias significativas para las escalas ASES, DASH, ni EVA .El grupo tratado de forma quirúrgica obtuvo a los 12 meses una puntuación media en la escala Constant mayor, diferencia estadísticamente significativa(75.1 þ/-10.3 vs. 51.9 þ/-12.4 p » 0.001). Además presentaban mayor rango de movilidad para flexión y rotación externa (128.9 þ/-17 versus 99.3 þ/-20.1 p » 0.001, and 35.7 þ/-13.9 vs. 23.4 þ/-15.5 p » 0.032). El 43% de los pacientes tratados mediante artroplastia reversa presentaban tuberosidades normoposicionadas y mejores resultados en las escalas versus pacientes con tuberosidades ausentes o malposicionadas. El grupo sometido a cirugía no presentó mayor tasa de complicaciones.CONCLUSIONES El tratamiento conservador en las fracturas de EPH en tres y cuatro fragmentos en pacientes ancianos ofrece buenos resultados en cuanto a dolor y funcionalidad en la mayoría de pacientes. Falta por definir qué pacientes por tener alta demanda funcional serían candidatos a tratamiento quirúrgico de entrada

OBJECTIVE This study compared functional results in two cohorts of older adults with three- and four-part proximal humeral fractures (PHFs) per Neer's classification treated with reverse shoulder arthroplasty (RSA) or nonoperative management. MATERIALS AND METHODS Ambispective, non-randomized study with two cohorts of patients aged 75 or older treated with RSA (n » 15) or nonoperative management (n » 16) with a minimum follow-up period of 12 months. We analyzed the American Shoulder and Elbow Surgeons (ASES), Constant-Murley, and Disabilities of the Arm, Shoulder, and Hand (DASH) scores and the visual analog scale (VAS) for pain at 3, 6, and 12 months. In addition, we recorded radiological findings and surgical complications. RESULTS The mean Constant-Murley score at 12 months was significantly higher for the RSA group (75.1 þ/- 10.3 vs. 51.9 þ/- 12.4, p » 0.001). There were no differences in ASES, DASH, and VAS scores. Statistically significant differences for flexion and external rotation in abduction favored the RSA group (128.9 þ/- 17.0 versus 99.3 þ/- 20.1, p » 0.001, and 35.7 þ/- 13.9 vs. 23.4 þ/- 15.5, p » 0.032, respectively). For the RSA group, tuberosity positioning was correct in 43% of subjects. These patients presented better scores than those with malpositioned or absent tuberosities but with no statistical significance. Complications in the surgical group were not higher. CONCLUSIONS Nonoperative treatment is a valid option regarding pain and functionality in elderly patients with three- and four-part PHFs. Characteristics of patients with high demands who may be candidates for the initial surgical treatment remain to be defined

Recurrent Anterior Shoulder Dislocation After Trauma with Coracoid Apophysis Fracture - A Rare Association / Luxação anterior recorrente do ombro após traumatismo com fratura apófise coracoide - Uma associação rara

Abstract Anterior dislocations represent about 96% of total shoulder dislocations, with recurrence/instability being more common in young patients. Injury of other shoulder structures is frequent, namely bony Bankart lesion. However, the association with coracoid apophysis fracture is very rare. The present article describes the clinical case of a 67-year-old man who presented to the emergency department with complaints of persistent omalgia, with acute episodes, beginning after a fall from his own height. The patient also presented history of shoulder trauma 3 months earlier, which was evaluated at another hospital. Shoulder anterior dislocation was observed radiographically, and the computed tomography (CT) confirmed bone erosion of the anteroinferior part of the glenoid (bone loss of about 50% of the anteroposterior diameter in the lower region of the glenoid), with almost complete resorption of the bony Bankart lesion (apparent in later analysis of the radiography of the initial traumatic episode). Connectedly, a transverse fracture of the coracoid apophysis (type II in the Ogawa classification) was diagnosed. The patient was submitted to surgical treatment, with anterior bone stop confection using the remnant of the fractured fragment of the coracoid supplemented by tricortical autologous iliac graft, fixed with cannulated screws (according to the Bristow-Latarjet and Eden-Hybinett techniques). In the postoperative follow-up, a good functional result was observed, with no new episodes of dislocation and no significant pain complaints. A rare association of shoulder lesions is described, and the challenge of their treatment is highlighted, given the late diagnosis, as in the case presented.

Resumo As luxações anteriores representam cerca de 96% do total de luxações do ombro, sendo a recidiva/instabilidade mais comum em pacientes jovens. A lesão de outras estruturas do ombro é frequente, nomeadamente a lesão óssea de Bankart. Contudo, a associação com a fratura da apófise coracoide é muito rara. Este artigo descreve o caso clínico de um homem de 67 anos que recorreu ao serviço de urgência com queixas de omalgia persistente, com episódios de agudização, iniciados após queda da própria altura. O paciente apresentava ainda histórico de trauma do ombro 3 meses antes, avaliado em outro hospital. A luxação anterior do ombro foi constatada radiograficamente, e a tomografia computorizada (TC) do ombro confirmou erosão óssea da vertente anteroinferior da glenoide (perda óssea de cerca de 50% do diâmetro anteroposterior na região inferior da glenoide), com reabsorção quase completa de lesão óssea de Bankart (aparente em análise a posteriori da radiografia do episódio traumático inicial). Associadamente, foi diagnosticada uma fratura transversa da apófise coracoide (tipo II da classificação de Ogawa). O paciente foi submetido ao tratamento cirúrgico, com confecção do batente ósseo anterior utilizando remanescente do fragmento fraturado do coracoide suplementado por enxerto autólogo tricortical do ilíaco, fixados com parafusos canulados (de acordo com as técnicas de Bristow-Latarjet e Eden-Hybinett). No seguimento pós-operatório, foi observado um bom resultado funcional, sem novos episódios de luxação e sem queixas álgicas significativas. Descreve-se uma associação rara de lesões do ombro, e salienta-se o desafio do tratamento das mesmas dado o seu diagnóstico tardio, como no caso apresentado.

The Hertel classification can't predict the risk of humeral head osteonecrosis after osteosynthesis using an anterolateral approach.

BACKGROUND: Proximal humeral fractures can progress to osteonecrosis of the humeral head. Hertel developed a binary classification system (12 subtypes) and demonstrated that some patterns have more risk to develop osteonecrosis. Hertel described the prevalence and the risk factors for Humeral head osteonecrosis after osteosynthesis using a Deltopectoral approach. Few studies have evaluated the prevalence and the capacity of Hertel's classification to predict Humeral Head osteonecrosis following osteosynthesis of proximal Humeral fractures through the anterolateral approach. The objectives of this study were to correlate osteonecrosis predictors established by the Hertel classification with the risk of developing osteonecrosis and its prevalence after osteosynthesis using the anterolateral approach. METHODS: This was a retrospective study of patients who underwent osteosynthesis of proximal humerus fractures using an anterolateral approach. Patients were divided into two groups: high risk for necrosis (group 1) and low risk for necrosis (group 2) according to Hertel's criteria. The overall prevalence of osteonecrosis and the prevalence in each group were calculated. A radiological examination was performed in the true anteroposterior (Grashey), scapular, and axillary views, before and after the operation (minimum 1 year after surgery). A Kaplan-Meier curve was used to assess the pattern of the temporal evolution of osteonecrosis. The groups were compared using the Chi-square test or Fisher's exact test. The unpaired t-test (parametric variables - age) and the Mann-Whitney test (non-parametric time between trauma and surgery) were used. RESULTS: In total, 39 patients were evaluated. The postoperative follow-up time was 14.5 ± 3.3 months. The time to onset of necrosis was 14.1 ± 3.9 months. Sex, age, and time between trauma and surgery did not influence the risk of necrosis. Type 2, 9, 10, 11, and 12, or fractures with posteromedial head extension less than or equal to 8 mm, or diaphysis deviation greater than 2 mm, as well as grouping did not influence the risk for osteonecrosis. CONCLUSIONS: Hertel's criteria were not able to predict the development of osteonecrosis after osteosynthesis of proximal humerus fractures performed through the anterolateral approach. The total prevalence of osteonecrosis was 17.9% with a tendency toward an increased incidence after 1 year of surgical treatment.

Fixação de fratura intra-articular da glenoide com placa bloqueada de rádio distal: relato de caso / Fixation of intra-articular glenoid fracture with a locked plate distal radius: case report

As fraturas de glenoide são raras, porém, exigem abordagem de tratamento criteriosa para que o paciente não tenha que conviver com limitações posteriores decorrentes de falhas na fixação adequada. Além dos materiais comumente utilizados para a fixação da fratura, outros vêm sendo testados como a placa bloqueada de rádio distal, aplicada no presente estudo e em alguns outros levantamentos, sempre com bons resultados de recuperação da estabilidade de amplitude de movimentos pelos pacientes. O procedimento cirúrgico usual é a redução aberta e fixação interna (RAFI), e suas opções de materiais para a fixação são limitadas, o que pode gerar dificuldades no procedimento, materiais desenhados para outras finalidades são alternativas para pacientes com esse tipo de fratura. O objetivo desse trabalho foi de relatar o caso de um paciente com fratura complexa de glenoide, submetido a intervenção cirúrgica para a recuperação da estabilidade articular e correta movimentação e os resultados alcançados por uma nova técnica, considerando-se que na falta do material comumente aplicado, optou-se pela aplicação de placa utilizada comumente nos procedimentos de fixação de fraturas de rádio distal. Trata-se de paciente do sexo masculino, JASG, 62 anos, queda de andaime de 4,5 metros de altura, trauma direto no ombro ocorrido em setembro de 2021, na queda, choque contra anteparo, atingindo a região anterior do ombro direito. Procurou serviço externo, após primeiro atendimento foi constatada apenas fratura escapular e indicado o tratamento conservador. Em 2021 o paciente procura o ambulatório do HSPM com queixa de dor intensa e limitação dos movimentos do ombro. Com base na avaliação clínica e exames radiográficos, foi indicado o tratamento cirúrgico. A cirurgia foi realizada em novembro de 2021. O procedimento foi realizado com o paciente em decúbito lateral esquerdo, via de acesso posterior na escápula direita, com anestesia geral e bloqueio supraescapular guiado por ultrassom, a opção foi a abordagem pela via descrita por Judet. As fraturas de glenoide são raras, porém, exigem abordagem de tratamento criteriosa para que o paciente não tenha que conviver com limitações posteriores decorrentes de falhas na fixação adequada. Além dos materiais comumente utilizados para a fixação da fratura, outros vêm sendo testados como a placa bloqueada de rádio distal, aplicada no presente estudo e em alguns outros levantamentos, sempre com bons resultados de recuperação da estabilidade de amplitude de movimentos pelos pacientes.

Conceptos actuales: ventajas del clavo endomedular para fracturas del húmero proximal / Current concepts: advantages of intramedullary nail for proximal humerus fractures

Las fracturas de húmero proximal (FHP) son una de las fracturas más frecuentes en la población anciana. La reducción abierta y fijación interna (RAFI) generalmente está indicada para pacientes con una FHP desplazada en jóvenes o pacientes mayores con alta demanda funcional y buena calidad ósea. No se ha llegado a un consenso sobre la técnica de fijación ideal. La RAFI con placas ha sido la más utilizada, pero se han reportado altas tasas de reintervenciones y complicaciones globales en la literatura. La necesidad de agregar técnicas de aumentación a la RAFI con placas bloqueadas en fracturas complejas puede resultar en un tiempo quirúrgico más largo, abordajes extensos y mayores costos. Debido a esto, se hace necesario considerar otras opciones para la osteosíntesis de FHP. Con una mayor comprensión de los mecanismos de falla de la osteosíntesis, la fijación intramedular se ha convertido en una opción de tratamiento aceptada para las FHP con ventajas biomecánicas y biológicas. La fijación intramedular para las FHP ha demostrado menor tiempo quirúrgico, sangrado intraoperatorio, tiempo hasta la unión ósea y menores tasas de infecciones, que las placas bloqueadas. La fijación intramedular es una opción válida para que las fracturas complejas se resuelvan con un implante que por sí solo puede satisfacer en gran medida todas las necesidades de aumento requeridas por una placa bloqueada

Proximal humeral fractures are one of the most frequent fractures in the elderly population. Open reduction and internal fixation (ORIF) is generally indicated for young patients and older patients with high functional demands and good bone quality. No consensus has been reached regarding the ideal fixation technique. Although ORIF with plates is the most widely used technique, high re-intervention rates and global complications with locked plate fixation have been reported in the literature. Addition of augmentation techniques to locked plate fixation in complex fractures may result in longer surgical times, extensive approaches, and higher costs. Therefore, considering other options for ORIF is necessary. With a greater understanding of the mechanisms of fixation failure, intramedullary fixation has become the accepted treatment option for proximal humeral fractures considering the specific biomechanical and biological advantages. Compared with ORIF with locked plates, intramedullary fixation for proximal humeral fractures has low surgical time, intraoperative bleeding, time to bone union, and rate of infections. Intramedullary fixation is a valid option to resolve complex fractures with an implant that may largely supply all the augmentation requirements of a locked plate.

Computed Tomography Does Not Improve Intra- and Interobserver Agreement of Hertel Radiographic Prognostic Criteria.

Background and Objectives: Proximal humerus fractures are the second most frequent site of avascular necrosis (AVN), occurring in up to 16% of cases. The Hertel criteria have been used as a reference for the prediction of humerus head ischemia. However, these are based solely on the use of radiographs, which can make interpretation extremely difficult due to several reasons, such as the overlapping fragments, severity of the injury, and noncompliant acute pain patients. The objectives of the study were to evaluate the role of computed tomography (CT) in the interpretation of the Hertel criteria and to evaluate the intra- and interobserver agreement of orthopedic surgeons, comparing their area of expertise. Materials and Methods: The radiographs and CT scans of 20 skeletally mature patients who had fractures of the proximal humerus were converted to jpeg and mov, respectively. All images were evaluated by eight orthopedic surgeons (four trauma surgeons and four shoulder surgeons) in two different occasions. The intra- and interobserver agreement was assessed by using the Kappa coefficient. The level of significance was 5%. Results: There was a weak-to-moderate intraobserver agreement (κ < 0.59) for all examiners. Only the medial metaphyseal hinge greater than 2 mm was identified by 87.5% of evaluators both in the radiographic and CT examinations in the two rounds of the study (p < 0.05). There was no significant interobserver agreement (κ < 0.19), as it occurred only in some moments of the second round of evaluation. Conclusions: The prognostic criteria for humeral head ischemia evaluated in this study showed weak intra- and interobserver agreement in both the radiographic and tomographic evaluation. CT did not help surgeons in the primary interpretation of Hertel prognostic criteria used in this study when compared to the radiographic examination.

[Direct medical cost of late rehabilitation in workers with conservatively managed proximal humerus fracture]. / Costo médico directo de la rehabilitación tardía en trabajadores con fractura proximal de húmero de manejo conservador.

INTRODUCTION: Eighty percent of the Proximal humerus fractures are not displaced or minimally displaced and stable. The international treatment recommendation is conservative. Immobilization of the limb carries risk of stiffness, pain and decreased function. Currently being used rehabilitation programs with early mobilization of the injured shoulder within the first week post-fracture, with evidence of early functional and labor recovery and with no risk for displacement of fragments. However, in our country, these patients start rehabilitation late, which leads to a delay in the recovery of functionality and delay in returning to work, translating into increased costs. At the moment there is no national benchmark for the cost of this late-onset rehabilitation. MATERIAL AND METHODS: From a non-probabilistic sample for convenience, were analyzed records of 52 patients, treated in the period from January to December 2019. Inclusion criteria were workers diagnosed with a proximal humeral fracture, conservative management; exclusion criteria were peripheral nerve injury, aggregate fracture or surgically treated. RESULTS: The mean direct medical cost was $19,090.69 Mexican pesos, directly proportional to the days of stay in the unit and disability. CONCLUSION: Late rehabilitation leads to more days of disability than recommended by the based guidelinesin the workload, therefore, higher cost.

INTRODUCCIÓN: Ochenta por ciento de las fracturas de húmero proximal son no desplazadas o mínimamente desplazadas y estables. La recomendación internacional de tratamiento es de uno conservador. La inmovilización de la extremidad conlleva riesgo de rigidez, dolor y disminución de función. Actualmente se están empleando programas de rehabilitación con movilización precoz del hombro lesionado dentro de la primera semana postfractura, con evidencia de recuperación funcional y laboral precoces y con ausencia de riesgo para desplazamiento de fragmentos. Sin embargo, en nuestro país, estos pacientes inician la rehabilitación de forma tardía, lo que conlleva un retardo en la recuperación de funcionalidad y retardo en reincorporación laboral, traduciendo incremento en costos. Al momento no existe un referente nacional del costo que implica esta rehabilitación de inicio tardío. MATERIAL Y MÉTODOS: De una muestra no probabilística por conveniencia, se analizaron expedientes de 52 pacientes, atendidos en el período de Enero a Diciembre de 2019. Los criterios de inclusión fueron trabajadores con diagnóstico de fractura de húmero proximal, manejo conservador; criterios de exclusión fueron lesión de nervio periférico, fractura agregada o postoperados. RESULTADOS: La media del costo médico directo fue $19,090.69 pesos mexicanos, con relación directamente proporcional a los días de estancia en la unidad y de incapacidad. CONCLUSIÓN: La rehabilitación tardía conlleva más días de incapacidad que las recomendadas por las guías con base en la carga de trabajo, por ende, mayor costo.

Nonoperative Treatment for Displaced Proximal Humeral Fractures in Elderly Patients: Correlation Between Deviations and Clinical Outcomes / Tratamento não operatório de fraturas desviadas da extremidade proximal do úmero em idosos: Correlação entre os desvios e os resultados clínicos

Abstract Objectives To describe the functional result of the conservative treatment of displaced proximal humerus fractures (PHF) using the American Shoulder and Elbow Surgeons (ASES) score after 12 months and assess whether the different initial classifications and radiographic measurements are related to clinical results. Methods Forty patients > 60 years old, with displaced PHUs submitted to conservative treatment were evaluated at standardized times (3, 6, and 12 months). The American Society of Shoulder and Elbow Surgeons (ASES), Constant-Murley and Single Assessment Numeric Evaluation (SANE) scales were used as clinical outcomes. Radiographic variables included the Neer and Resch classifications, the presence and displacement of tuberosity fracture, metaphyseal comminution, medial periosteal lesion, and angular and translational deviations of the head in the coronal and sagittal plane. Results The result of the ASES score was 77.7 23.2 for the whole sample, the mean absolute values of the Constant-Murley score were 68.7 16 and 82.6% for the scale relative to the contralateral side. The SANE scale at 12 months was 84.8 19. We observed that the severity of the Neer classification and the coronal plane angular deviation (measured by the head-shaft angle) and the presence of fractures in both tuberosities negatively influenced the ASES score after 12 months of treatment. Conclusion Nonoperative treatment of displaced proximal humerus fractures in elderly patients results in good clinical results. Clinical results are negatively influenced by the angular deviation of the humeral head and the presence of fractures of the greater and lesser tubercles, as well as by the Neer classification.

[Functional results after shoulder hemiarthroplasty for proximal humerus fracture: experience in our center]. / Resultados funcionales tras hemiartroplastía de hombro por fractura de húmero proximal: experiencia en nuestro centro.

INTRODUCTION: shoulder hemiarthroplasty is being relegated as a treatment for non-osteosynthetic proximal humerus fractures. Our objective is to analyze the functional results of patients treated with hemiarthroplasty for this reason in our hospital. MATERIAL AND METHODS: cross-sectional descriptive study that includes patients operated between February 2016 and November 2021; 24 patients, with an average follow-up of 44.6 months. Active joint balance, the Constant-Murley test, the DASH questionnaire and current pain (VAS) were collected. The radiographic parameters analyzed were the number of fracture fragments and the consolidation of the tuberosities. RESULTS: a mean of 71.65 ± 13.75 was obtained in the Constant-Murley and 18.14% ± 13.92 in the DASH. For shoulder flexion, the mean was 108.75° ± 41.26; 104.5° ± 43.68 for abduction and 33° ± 14.73 for external rotation. About internal rotation, 60% of the patients reached the scapular plane. Average VAS was 1.25 ± 1.74. Consolidated tuberosities in 90.5%. There were no significant differences comparing the Constant-Murley test, DASH or rotations between both, over and under 65 years old group of patients. Those over 65 years of age obtained a mean flexion of 125.91° ± 26.82 whereas those under 87.78° ± 26.82 (p = 0.038). The mean abduction in those over 65 was 125.45 ± 28.94 vs 78.89 ± 46.29 in the young group (p = 0.012). CONCLUSION: hemiarthroplasty provides quality of life with acceptable functionality and good pain control, therefore it should continue to be an alternative to consider in selected patients.

INTRODUCCIÓN: la hemiartroplastía de hombro está siendo relegada como tratamiento de fracturas de húmero proximal no osteosintetizables. Nuestro objetivo es analizar los resultados funcionales de los pacientes tratados con hemiartroplastía por este motivo en nuestro centro. MATERIAL Y MÉTODOS: estudio descriptivo transversal que incluye a los pacientes intervenidos entre Febrero de 2016 y Noviembre de 2021; 24 pacientes, con un seguimiento medio de 44.6 meses. Fueron recogidos el balance articular activo, el test de Constant-Murley, el cuestionario DASH y el dolor actual (EVA). Como parámetros radiográficos se analizó el número de fragmentos de fractura y la consolidación de las tuberosidades. RESULTADOS: se obtuvo una media de 71.65 ± 13.75 en el Constant-Murley y de 18.14% ± 13.92 en el DASH. Para flexión de hombro la media fue de 108.75° ± 41.26; 104.5° ± 43.68 para abducción y 33° ± 14.73 para rotación externa. En rotación interna 60% llegaba hasta plano interescapular. EVA medio de 1.25 ± 1.74. Tuberosidades consolidadas en 90.5%. No hubo diferencias significativas entre el Constant-Murley, DASH ni rotaciones de pacientes mayores y menores de 65 años. Los mayores de 65 años obtuvieron flexión media de 125.91° ± 26.82 y los menores de 87.78° ± 26.82 (p = 0.038). La abducción media en mayores de 65 fue de 125.45 ± 28.94 versus 78.89 ± 46.29 en el grupo joven (p = 0.012). CONCLUSIÓN: la hemiartroplastía otorga calidad de vida con aceptable funcionalidad y buen control del dolor, por lo que debe continuar siendo una alternativa a tener en cuenta en pacientes seleccionados.

Influencia de la consolidación de las tuberosidades en los resultados clínicos de la prótesis invertida para fracturas de húmero proximal / Influence of the consolidation of the tuberosities on the clinical outcomes of the reverse arthroplasty in proximal humerus fractures

Objetivo: Comparar los resultados clínicos y las complicaciones de una serie consecutiva de pacientes con fracturas de húmero proximal tratados con prótesis invertida de hombro y con consolidación anatómica de las tuberosidades o sin ella. Materiales y Métodos: Se evaluó a 113 pacientes >65 años con fractura de húmero proximal tratados con prótesis invertida de hombro. Setenta presentaron consolidación anatómica de las tuberosidades y 43, ausencia de consolidación. Se evaluó el rango de movilidad, y se utilizaron los puntajes de Constant-Murley, ASES, SANE y la escala analógica visual. Se documentaron todas las complicaciones y las reoperaciones. Resultados: El seguimiento promedio fue de 56 meses (rango 24-96) y la edad media era de 73 años (rango 65-83). La elevación activa y la rotación interna medias posoperatorias fueron de 131° (± 14) y 27° (± 5), respectivamente. La rotación externa posoperatoria media en abducción y aducción fue de 27° (± 1) y 15° (± 6), respectivamente. La escala analógica visual promedio posoperatoria fue de 1,7 (± 0,8). Los puntajes ASES, de Constant-Murley y SANE promedio fueron de 76 (± 6), 62 (± 11) y 74% (± 7), respectivamente. La elevación anterior, la rotación externa y los puntajes funcionales promedio finales ASES y de Constant-Murley fueron significativamente mejores en el grupo con consolidación de las tuberosidades. Conclusiones: En pacientes >65 años con fractura de húmero proximal tratados con prótesis invertida de hombro tanto la movilidad posoperatoria, como los puntajes funcionales fueron significativamente mejores en los pacientes con consolidación anatómica de las tuberosidades. Nivel de Evidencia: III

Objective: The objective of this study was to compare the clinical outcomes and complications of a consecutive series of patients with proximal humerus fractures (PHF) treated with reverse shoulder arthroplasty (RSA), with and without anatomical healing of the tuberosities. Materials and Methods: We evaluated 113 patients >65 years old with PHF treated with RSA. Seventy patients presented anatomical healing of the tuberosities and 43 presented absence of healing. Range of motion (ROM), Constant score, ASES score, visual analog scale (VAS) and the score of the numerical evaluation of single evaluation (SANE) were evaluated. Results: The mean follow-up was 56 months (range, 24-96 months) and the mean age was 73 years (range, 65-83 years). Mean postoperative active elevation and internal rotation were 131° (±14) and 27° (±5), respectively. The mean postoperative external rotation in abduction and adduction was 27° (±1) and 15° (±6) respectively. The mean postoperative VAS was 1.7 (±0.8). The mean ASES, Constant and SANE scores were 76 (±6), 62 (±11) and 74% (±7), respectively. Anterior elevation, external rotation, and final mean ASES and Constant functional scores were significantly better in the group with tuberosity healing than in the group without healing. Conclusions: In patients >65 years old with PHF treated with RSA, both postoperative ranges of motion and functional scores were significantly better in patients where anatomic tuberosity healing was achieved than in those where it was not achieved.

Aumento con injerto estructural endomedular en la osteosíntesis de fracturas de húmero proximal / Endosteal strut allograft augmentation in the osteosynthesis of proximal humerus fractures

Introducción: Las fracturas de húmero proximal son frecuentes, particularmente en la población mayor. Los resultados de la fijación con placa bloqueada siguen siendo impredecibles. El soporte de la columna medial jugaría un rol significativo. Nuestro pro-pósito fue evaluar los resultados de la osteosíntesis de húmero proximal con aloinjerto óseo estructural. Materiales y métodos: Se evaluaron los resultados clínico-radiológicos en 12 pacientes con fractura de húmero proximal tratados con placa bloqueada e injerto estructural endostal. Se definió como pérdida de reducción a un cambio del ángulo cervicodiafisario >5° o en la altura de la cabeza humeral >3 mm. La evaluación clínica incluyó rango de movilidad, puntaje de Constant-Murley, valor subjetivo del hombro, escala analógica visual para dolor y retorno a la actividad habitual. Resultados: Doce pacientes completaron el seguimiento (edad promedio 62.8 años). Diez mantuvieron la reducción. El puntaje promedio de Constant-Murley fue de 82,1; el del valor subjetivo del hombro, del 80%, y el de la escala analógica visual, de 1,9. La elevación anterior fue de 138,3°; la rotación externa, de 49,5°, y la rotación interna a nivel de la vértebra de L3. La diferencia de la altura de la cabeza humeral y el ángulo cervicodiafisario fue de 2,3 mm y 4,92°. No hubo complicaciones. Conclusiones: La osteosíntesis con placa bloqueada y aumento con injerto estructural endomedular es una técnica fiable para tratar fracturas de cuello quirúrgico del húmero. Proporciona soporte al cuello humeral y mantiene la reducción en la fractura de húmero proximal con rotura de la bisagra medial. Nivel de Evidencia: IV

Introduction: Proximal humeral fractures (PHF) are common, particularly in the elderly. To date, locking plate fixation continues to provide unpredictable outcomes. Medial hinge support plays a significant role in stability until the bone heals. We aim to evaluate the outcomes of plate fixation with endosteal strut allograft augmentation in the treatment of PHF. Materials and methods: We evaluated clinical and radiological outcomes in the medium-term follow-up of 12 patients with PHF who were treated with plate fixation and strut allograft augmentation. The strut allograft was introduced into the humeral shaft to add support to the medial hinge. We compared the final follow-up radiographs to those taken immediately after surgery. We defined a loss of reduction if the change in Humeral Head Height or the Neck-Shaft Angle measured over 3 mm or 5°, respectively. The clinical evaluation included range of motion, Constant-Murley (CM) score, Subjective Shoulder Value (SSV), Visual Analog Scale (VAS), and return to daily activities. Results: Twelve patients completed follow-up. The patients' average age was 62.8. Ten patients healed without loss of reduction. Average CM and SSV scores were 82.1 and 80%, respectively, and average VAS was 1.9. Anterior elevation averaged 138.3°, external rotation 49.5°, and internal rotation at L3 level. The mean differences in HHH and NSA were 2.3 mm and 4.92°, respectively. We recorded no complications associated to the procedure. Conclusion: Locking plate fixation with endosteal strut allograft augmentation is a reliable technique for the treatment of PHF. It provides support to the humeral neck and maintains reduction in fractures with disruption of the medial hinge. Level of Evidence: IV

Axial view of the shoulder. Description of a technique / Proyección axial de hombro. Descripción de una técnica

Shoulder fracture is one of the most frequently treated injuries in trauma centers, with an overall incidence that appears to have increased in recent years, ranging from 219 to 419 cases per 100 000 person-years. In clinical terms, shoulder girdle injury is difficult to diagnose due to the close relationship between the shoulder and the chest, and imaging identification of the different types of injuries can be challenging. In this context, X-rays are the most appropriate method and the cornerstone of the initial approach to shoulder trauma, and at least 3 views are recommended: true anteroposterior view (AP), axial or axillary projection or modified axial projection (Velpeau view), and lateral scapula shoulder or Y view. However, patient positioning is often problematic due to the additional pain associated with limb mobilization in order to achieve the proper position for radiographic projection. The following is the description of a technique for performing an axial shoulder projection that is free of these complications, easy to standardize, and applicable to any traumatic or degenerative disease of the proximal humerus or glenohumeral joint, which, to the best of the authors' knowledge, has not been previously published.

El trauma de hombro es una de las patologías más frecuentemente vista en los centros de trauma con una incidencia global que aparentemente ha aumentado en los últimos años y que se ha reportado entre 219 a 419 casos por 100000 personas-año. El diagnóstico del trauma de la cintura escapular no es fácil clínicamente por la íntima relación entre el hombro y el tórax, y la identificación imagenológica de las distintas lesiones puede ser desafiante. Las radiografías son el método más apropiado y piedra angular del estudio inicial en el trauma de hombro, el set de trauma tiene al menos 3 planos: la vista Anteroposterior (AP) verdadera, una proyección axial o axilar o su modificación descrita por Velpeau. Y una proyección Y de escápula. Sin embargo, el posicionamiento del paciente muchas veces no es fácil por el dolor adicional que puede generar la movilización de la extremidad para lograr la posición adecuada para la proyección radiográfica. Describimos una técnica para realizar una proyección axial de hombro sin estas dificultades, fácilmente estandarizable para cualquier patología traumática o degenerativa del húmero proximal o de la articulación gleno-humeral y que creemos no ha sido publicada previamente.

Bilateral fracture of the shoulders following epileptic seizures: a case report / Fratura bilateral de ombros após convulsões epilépticas: relato de caso

Convulsive seizures caused by hyponatremia occur when this condition is severe and develops quickly, resulting in a brain's adaptive inability to contain brain swelling. Seizures are rarely the cause of shoulder fractures. This is a case report of bilateral humerus fracture following a single epileptic seizure caused by drug hyponatremia, an unconventional event in medical practice. A 69-year-old woman was admitted to the emergency room after a single tonic-clonic seizure with spontaneously ceased sphincter relaxation, showing Glasgow 6. No falls or restraint were reported by observers. When alert, the patient reported pain and difficulty moving both arms. During examination, the movement was li- mited to the right and left. Anteroposterior radiographs revealed bilateral fracture at the neck of humerus. To complement inves- tigation for further lesions, a computed tomography confirmed bilateral fracture-dislocation with impaction of the humeral head with the glenoid. Atraumatic bilateral fracture-dislocation of the humerus after epileptic seizure is a very rare event. It is believed that some of these diagnoses have been neglected due to the difficulty of characterizing the patient's pain in a postictal state. The importance of a detailed physical examination shall be emphasized in risk groups such as the polymedicated elderly.

Tuberosity Healing after Reverse Shoulder Arthroplasty for Proximal Humerus Fractures: Is there Clinical Improvement? / Consolidação dos tubérculos na artroplastia reversa do ombro após fratura proximal do úmero: Existe melhoria nos resultados funcionais?

Abstract Objective To compare the functional results of patients with complex proximal humerus fracture submitted to total shoulder reverse arthroplasty with and without tuberosity healing. The secondary goal was to know the tuberosity healing rate after reverse shoulder arthroplasty with our surgical technique. Methods A retrospective, cohort type study, with a prospective database collection. In total, 28 patients fulfilled the inclusion criteria: age ≥ 65 years, reverse shoulder arthroplasty for complex proximal humerus fracture (type-3 or -4, according to Neer), and a minimum of 24 months of follow-up. At six months of follow-up, all of the patients were evaluated radiographically for tuberosity, and then they were divided into 2 groups: those with healed tuberosities and those with non-healed tuberosities. A clinical evaluation using the Constant score, active range of motion and the Visual Analog Scale (VAS) at the last follow-up was also performed. Results Tuberosity healing occurred in 21 patients (76.3%). There were statistically significant differences in the Constant scoring system (p < 0.001), forward elevation (p = 0.020), internal rotation (p = 0.001) and external rotation (p = 0.003) when comparing the group of healed tuberosities with the group of non-healed tuberosities. No differences were found regarding the VAS score. Conclusion Tuberosity healing results in an improvement of the functional outcomes of patients submitted to reverse shoulder arthroplasty as a treatment for complex proximal humeral fractures in the elderly.

Resumo Objetivo Comparar os resultados funcionais entre pacientes com fratura complexa do úmero proximal submetidos a artroplastia reversa com tubérculos consolidados e tubérculos não consolidados. O objetivo secundário foi determinar a taxa de consolidação dos tubérculos com este tipo de prótese. Métodos Estudo de tipo coorte, retrospectivo, com coleta prospectiva de dados. No total, 28 pacientes cumpriram os critérios de inclusão: idade superior a 65 anos, prótese reversa do ombro por fratura complexa do úmero proximal (3 ou 4 partes, segundo Neer), e tempo de seguimento mínimo de 24 meses. Aos seis meses, todos os pacientes foram avaliados radiograficamente quanto à consolidação dos tubérculos e divididos em dois grupos: grupo com tubérculos consolidados e grupo com tubérculos não consolidados. A avaliação funcional realizou-se segundo o sistema de pontuação de Constant, da amplitude de movimento ativo, e da Escala Visual Analógica (EVA) à data da última consulta. Registaram-se todas as complicações. Resultados A consolidação dos tubérculos ocorreu em 21 pacientes (76,3%). Verificou-se diferenças estatisticamente significativas no sistema de pontuação de Constant (p < 0.001), elevação anterior (p = 0.020), rotação interna (p = 0.001) e externa (p = 0.003), quando se comparou o grupo dos tubérculos consolidados com o grupo dos tubérculos não consolidados. Não houve diferenças significativas na EVA entre os 2 grupos. Conclusão A consolidação dos tubérculos traduz uma melhoria dos resultados funcionais em pacientes submetidos a artroplastia reversa do ombro como tratamento de fraturas complexas do úmero proximal em idosos.

[Alteration of X-ray measurements in proximal humerus osteosynthesis with intramedullary nail]. / Alteración de mediciones radiográficas en osteosíntesis de húmero proximal con clavo centromedular.

INTRODUCTION: The quality of reduction in proximal humerus fractures is valuable with radiographic criteria (Neck-shaft angle [NSA]; medial offset [MO]; distance head tuberosity [DHT] and subacromial space [SS]) that predict functionality. These criteria set for other implants are not described for the intramedullary nail. MATERIAL AND METHODS: Observational cohort study, retrospective, with patients 18 years, with osteosynthesis with intramedullary nail (2014 to 2017), evaluating demographic characteristics, severity of injury (Neer classification), progressive radiographic measurements and complications. RESULTS: 84 cases with an average age of 65 ± 2 years and an average follow-up of 13.9 months were analyzed. By Neer rating 40.4% were grade II, 29.7% grade III and 29.7% grade IV. Consolidation in varus increases to 10.7% at the end of follow-up, with Neer III and IV patients. The 140° deformity is prevalent for Neer II (n = 15/34). 30.9% have a change of neck-shaft angle of 10°. Overall 86.9% has HTD changes 5 mm. Cases Neer III/IV 32% has alteration of SS 5 mm. The most common complication is avascular necrosis (AVN) with 44% of cases. CONCLUSIONS: Radiographic measurements have changes in long-term follow-up. Alterations in NSA ( 10o) and SS ( 5 mm) occur in higher proportion of Neer III/IV patients, according to the severity of the fracture, favoring vicious consolidations in varus or valgus and increased presence of AVN.

INTRODUCCIÓN: La calidad de reducción en las fracturas de húmero proximal es posible valorarla a través de criterios radiográficos (ACD = ángulo cervicodiafisario; OM = offset medial; DTC = distancia tuberosidad-cabeza y ES = espacio subacromial), los cuales predicen la funcionalidad. Sin embargo, estos criterios establecidos para otros implantes no están descritos para el clavo centromedular. MATERIAL Y MÉTODOS: Estudio de cohorte observacional y retrospectivo en pacientes 18 años con osteosíntesis con clavo centromedular (durante el período de 2014 a 2017), en donde se evaluaron las características demográficas, severidad de lesión (clasificación de Neer) y las mediciones radiográficas progresivas y complicaciones. RESULTADOS: Se analizaron 84 casos, cuya edad en promedio fue de 65 ± 2 años y la media de seguimiento de 13.9 meses. Por clasificación de Neer: 40.4% fueron grado II; 29.7%, grado III y 29.7%, grado IV. La consolidación en varo aumenta 10.7% al final del seguimiento, siendo aquellos pacientes Neer grado III y IV los más frecuentes. La deformidad 140° predomina para Neer grado II (n = 15/34). En 30.9%, se presenta un cambio de ACD (ACD) 10°. En general, 86.9% tiene cambios de DTC 5 mm. En los casos Neer grado III/IV, 32% tiene una alteración de ES 5 mm. La complicación más frecuentemente es la necrosis avascular (NAV) con 44% de los casos. CONCLUSIONES: Las mediciones radiográficas presentan cambios en valoraciones a largo plazo. Las alteraciones en ACD ( 10o) y ES ( 5 mm) se dan en mayor proporción en aquellos pacientes Neer grado III/IV (acorde con la severidad de la fractura), lo que favorece consolidaciones viciosas en varo o valgo y una mayor presencia de NAV.
