Supra-inguinal fascia iliaca block in older-old patients for hip fractures: a retrospective study

Abstract Background: Pain management in hip fracture patients is of great importance for reducing postoperative morbidity and mortality. Multimodal techniques, including peripheral nerve blocks, are preferred for postoperative analgesia. Older-old hip fracture patients with high ASA scores are highly sensitive to the side effects of NSAIDs and opioids. Our aim was to investigate the effectiveness of the recently popularized Supra-Inguinal Fascia Iliaca Block (SIFIB) in this population. Methods: Forty-one ASA III-IV patients who underwent SIFIB + PCA (G-SIFIB) or PCA alone (Group Control: GC) after general anesthesia were evaluated retrospectively. In addition to 24-hour opioid consumption, Visual Analog Scale (VAS) scores, opioid-related side effects, block-related complications, and length of hospital stay were compared. Results: Twenty-two patients in G-SIFIB and 19 patients in GC were evaluated. The postoperative 24-hour opioid consumption was lower in G-SIFIB than in GC (p < 0.001). There was a statistically significant reduction in VAS scores at the postoperative 1st, 3rd, and 6th hours at rest (p < 0.001) and during movement (p < 0.001 for the 1st and 3rd hours, and p = 0.02 for the 6th hour) in G-SIFIB compared to GC. There was no difference in pain scores at the 12th and 24th hours postoperatively. While there was no difference between the groups in terms of other side effects, respiratory depression was significantly higher in GC than in G-SIFIB (p = 0.01). Conclusion: The SIFIB technique has a significant opioid-sparing effect and thus reduces opioid-related side effects in the first 24 hours after hip fracture surgery in older-old patients.

Desde el análisis biomecánico óseo de koch hasta el manejo contemporáneo de la fractura del fémur proximal / From koch's bone biomechanical analysis to contemporary proximal femur fracture management

Este artículo representa una revisión actual y completa de las fuerzas biomecánicas en el fémur proximal, tal como Koch presentó preliminarmente en su trabajo sobre la arquitectura ósea del fémur proximal. Su trabajo reflejó en la complejidad de las fracturas de fémur proximal y el manejo de las fracturas subtrocantéricas en paralelo con su clasificación y con la evolución de implantes. Existen múltiples formas de clasificar las fracturas subtrocantéricas; sin embargo, no existe un sistema de clasificación que se utilice para guiar el manejo quirúrgico. El tratamiento de las fracturas subtrocantéricas es la fijación quirúrgica, que implica el enclavado endomedular y placas de osteosíntesis. El tratamiento estándar es el enclavado endomedular con opciones de enclavado anterógrado y retrógrado. Aunque el enclavado anterógrado presenta una ventaja debido a las fuerzas deformantes, el enclavado retrógrado de las fracturas de fémur proximal ofrece menos tiempo quirúrgico y pérdida de sangre. Se han informado resultados similares entre los dos métodos. La toma de decisiones cuando se contempla el enclavado anterógrado versus retrógrado para las fracturas de fémur se basa principalmente en la constitución corporal y las lesiones asociadas, y no en la distancia de la fractura del fémur proximal a la región trocantérica

This article presents a current and comprehensive review of the biomechanical forces on the proximal femur, as preliminarily presented by Koch's cornerstone work on the bone architecture of the proximal femur. His work reflected on the complexity of proximal femur fractures and subtrochanteric fracture management in parallel with implant evolution and classification. Multiple ways of classifying subtrochanteric fractures exist, however, there is not one classification system that is used to guide operative management. The management of subtrochanteric fractures is surgical fixation which involves intramedullary nailing and plating (e.g., fixed angle and locking). The gold standard management is intramedullary nailing with antegrade and retrograde nail options. Though antegrade nailing presents an advantage due to the deforming forces, retrograde nailing of proximal femur fractures offers less operative time and blood loss. Similar outcomes have been reported between the two methods. Decision making when contemplating antegrade versus retrograde nailing for femur fractures is mostly driven by body habitus and associated injuries, and not by fracture distance of the proximal femur to the trochanteric region

Pipkin Type-II Femoral Head Fracture: A Biomechanical Evaluation by the Finite-Element Method / Fratura da cabeça femoral de tipo II de Pipkin: Avaliação biomecánica pelo método de elementos finitos

Abstract Objective To evaluate the biomechanical capacity of two forms of fixation for Pipkin type-II fractures, describing the vertical fracture deviation, the maximum and minimum principal stresses, and the Von Mises equivalent stress in the syntheses used. Materials and Methods Two internal fasteners were developed to treat Pipkin type-II fractures through finite elements: a 3.5-mm cortical screw and a Herbert screw. Under the same conditions, the vertical fracture deviation, the maximum and minimum principal stresses, and the Von Mises equivalent stress in the syntheses used were evaluated. Results The vertical displacements evaluated were of 1.5mm and 0.5mm. The maximum principal stress values obtained in the upper region of the femoral neck were of 9.7 KPa and 1.3 Kpa, and the minimum principal stress values obtained in the lower region of the femoral neck were of-8.7 KPa and -9.3 KPa. Finally, the peak values for Von Mises stress were of 7.2 GPa and 2.0 GPa for the fixation models with the use of the 3.5-mm cortical screw and the Herbert screw respectively. Conclusion The fixation system with the Herbert screw generated the best results in terms of reduction of vertical displacement, distribution of the maximum principal stress, and the peak Von Mises equivalent stress, demonstrating mechanical superiority compared to that of the 3.5-mm cortical screw in the treatment of Pipkin type-II fractures.

Os valores de tensão máxima obtidos na região superior do colo femoral foram de 9,7 KPa e 1,3 KPa, e os valores de tensão mínima obtidos na região inferior do colo femoral foram de -8,7KPa e -9,3 KPa. Por fim, os valores de pico da tensão equivalente de Von Misesforam de 7,2 GPa e2,0 GPa paraosmodelos de fixação com o uso do parafuso cortical de 3,5 mm e do parafuso de Herbert, respectivamente. Conclusão Osistema de fixação com parafuso de Herbert gerou os melhores resultados em termos de redução do deslocamento vertical, distribuição da tensão máxima e do pico da tensão equivalente de Von Mises, o que demonstra sua superioridade mecânica comparada à do parafuso cortical de 3,5 mm no tratamento da fratura tipo II de Pipkin.

Circumpsoas block - an anterior myofascial plane block for lumbar plexus elements: case report

Abstract In an attempt to improvise the analgesia in patients with femoral fractures, we aimed at depositing local anesthetic deep to anterior psoas fascia (APf) under ultrasound (US) guidance to block lumbar plexus elements which emerge lateral, anterior, and medial to the psoas major muscle. We termed this as circumpsoas block (CPB). Clinical and computed tomography contrast studies revealed that a continuous CPB infusion with a catheter provided a reliable block of the lumbar plexus elements. No adverse were events noted. We conclude that US guided CPB is a reliable technique for managing postoperative pain after surgery of femur fractures.

Fracturas basicervicales tratadas con clavo intramedular con tornillo cefálico único. Serie de casos y revisión bibliográfica / Basicervical fractures treated with single-screw cephalomedullary nail. Case series and review of the literature

Introducción: Debido a la inestabilidad rotatoria de las fracturas basicervicales, en estudios recientes, se sugiere el uso de una hoja espiral, doble tornillo o tornillos de compresión en lugar del tornillo cefálico único. Objetivo: Analizar los resultados de las fracturas basicervicales tratadas con tornillo cefálico único en nuestro centro. Materiales y Métodos: Estudio retrospectivo de una serie de casos formada a partir de la revisión de todas las fracturas extracapsulares de fémur proximal tratadas con clavo intramedular con tornillo cefálico único entre 2016 y 2020. Se revisaron las historias clínicas y las radiografías de 269 pacientes, y solo 12 (6,4%) de ellos cumplieron los criterios de inclusión (fracturas en dos fragmentos no patológicas y con seguimiento mínimo de 9 meses). Se evaluaron diferentes factores, como distancia punta-ápex, posición del tornillo cefálico, calidad de la reducción, tiempo quirúrgico, complicaciones y reintervención, y se analizaron las posibles diferencias entre los pacientes que sufrieron complicaciones y los que no. Resultados: Cuatro de los 12 pacientes tuvieron una falla de la fijación que evolucionó a cut-out (única complicación identificada en la muestra). No hubo diferencias estadísticamente significativas entre pacientes con cut-outo sin cut-out respecto al resto de las variables analizadas. Conclusiones: La elevada proporción de pacientes que desarrollaroncut-out sugiere considerar la hipótesis de que debería evitarse fijar las fracturas basicervicales con tornillo cefálico único. Dada su alta tasa de inestabilidad rotatoria, podría ser más apropiado el uso de implantes que la contrarresten. Nivel de Evidencia: IV

Background: Given the rotational instability of basicervical fractures, recent studies suggest using a spiral blade, a second screw or compression screws instead of single-screw cephalomedullary nail fixation. Objective: The aim of our study is to analyze the outcomes of basicervical fractures treated with single-screw cephalomedullary nails. Materials and Methods: This is a retrospective study based on a case series identified from all extracapsular femoral fractures treated with single-screw cephalomedullary nails in our hospital from 2016 to 2020. Clinical records and radiographs from 269 patients were reviewed; only 12 (6.4%) subjects met inclusion criteria (two-part non-pathologic fractures with at least a 9-month follow-up). Different factors were evaluated, including: tip-apex distance, cephalic screw position, reduction quality, surgical time, complications and re-operations; differences between patients who experienced complications and those who did not were also assessed. Results: Four subjects out of the 12 included patients experienced fixation failure and implant cut-out. There were no statistically significant differences between subjects with and without cut-out regarding the analyzed variables. Conclusions: The high cut-out rate observed in our sample suggests considering the hypothesis that single-screw cephalomedullary nail fixation should not be used in basicervical fractures. Alternative fixation devices capable of controlling the high rotational instability of these fractures may be preferable. Level of Evidence: IV

Morbimortalidad en pacientes con fracturas intertrocantéricas de cadera tratadas con clavos cefalomedulares. Valor predictivo del Índice de Movilidad de Parker / Morbidity and mortality in intertrochanteric hip fractures treated with cephalo-medullary nailing. Predictive value of the Parker mobility score

Introducción: La fractura de cadera es un factor independiente que aumenta la morbimortalidad. El objetivo de este estudio retrospectivo fue determinar la morbimortalidad en ancianos con fracturas intertrocantéricas de cadera tratadas con clavos cefalomedulares. Materiales y métodos: Se analizó a pacientes tratados con clavo cefalomedular por fractura intertrocantérica de cadera, entre 2018 y 2021, y un seguimiento mínimo de 12 meses. Se registraron: datos demográficos, comorbilidades, capacidad funcional con el Índice de Movilidad de Parker, complicaciones y tasa de mortalidad a los 12 meses y al final del seguimiento. Se identificaron las variables independientes relacionadas con complicaciones o muerte. Resultados: Se incluyó a 68 pacientes (seguimiento medio 23 meses). La tasa de complicaciones fue del 8,8%: infección urinaria, neumonía, trombosis venosa profunda y tres pérdidas de fijación del tornillo cefálico. Al comparar pacientes con complicaciones o sin ellas, hubo diferencias significativas en la edad cuando se produjo la fractura. Las tasas de mortalidad anual y al concluir el estudio fueron del 2,9% y 29,4%, respectivamente. Las diferencias fueron significativas en la incidencia de comorbilidades renales, demencia, el Índice de Comorbilidad de Charlson >4 y el puntaje de Parker <5 en quienes fallecieron. El puntaje de Parker <5 fue la variable independiente relacionada con muerte. Conclusiones: Las tasas de complicaciones y de mortalidad a los 12 meses del tratamiento de las fracturas intertrocantéricas inestables de cadera con clavos cefalomedulares es aceptable en ancianos. El riesgo de muerte aumenta significativamente si el puntaje de Parker es <5 antes de la fractura. Nivel de Evidencia: IV

Introduction: Hip fracture represents an independent predictor of morbidity and mortality. The aim of this retrospective study was to assess the morbidity and mortality associated with intertrochanteric hip fractures fixed with cephalomedullary nails. materials and methods: We analyzed all patients treated between 2018 and 2021 with a cephalomedullary nail for an intertrochanteric hip fracture, with a minimum follow-up of 12 months. We evaluated the demographic data, comorbidities, functional level through the Parker Mobility Score (PMS), complications, and mortality (12 months and at the end of follow-up). Variables related to postoperative complications or death were identified by bivariate and multivariate regression analyses. Results: 68 patients were included. The mean follow-up was 23 (range 12-40) months. The rate of complications was 8.8% (n=6), 1 urinary tract infection, 1 pneumonia, 1 deep vein thrombosis, and 3 (4.4%) cephalic screw fixation losses. Patients who had complications presented significant differences in age at the time of fracture. Mortality at 12 months and at the end of the study was 2.9% (n=2) and 29.4% (n=20) respectively. Those patients who died presented significant differences in the incidence of kidney comorbidities, dementia, a Charlson Comorbidity Index > 4, and a PMS < 5. PMS < 5 was the only independent variable related to mortality. Conclusions: Cephalomedullary nailing in unstable intertrochanteric hip fractures in elderly patients represents a treatment option that offers an acceptable complication rate and a low 12-month mortality rate. The risk of death is significantly increased in patients with low functional scores (Parker < 5) pre-fracture. Level of Evidence: IV

Objective: This retrospective study aimed to assess the functional outcomes and dislocation rate in the treatment with dual mobility prostheses in patients older than 65 with hip fractures. materials and methods: We analyzed all patients treated between 2017 and 2021 for hip fractures in our service. We included patients older than 65 years, treated with dual mobility cups, and a minimum follow-up of 24 months. We analyzed demographic data, comorbidities, functional outcomes (Parker score and Harris Hip Score, HHS), complications (infection, dislocation, loosening), reoperations, and revisions. Results: We included 102 hip fractures (75 medial and 27 intertrochanteric) in 102 patients. Seventy-four (72.5%) were women, the mean age was 80.59 ± 6.92 years, the mean Charlson index was 4.71 (range 3-10), and ASA was 2.47 (1-4). 93.1% started walking on the second postoperative day. 94.1% presented excellent or very good outcomes according to the HHS, the postoperative Parker index did not show significant differences in comparison to the preoperative one (p < 0.05). The average follow-up was 30 months (range 24-60). There were 8 (7.84%) complications: 2 (1.9%) deep vein thrombosis, 4 (3.9%) pulmonary thromboembolism, 3 infections (2.9%), and 1 (0.9%) dislocation. The reoperation rate was 2.9%. Conclusions: We obtained acceptable functional outcomes using dual mobility cups with a relatively low dislocation rate (0.9%). This suggests that these implants are an option to consider in treating these lesions. Level of Evidence: IV

Medición radiológica del extremo proximal del fémur / Radiological measurement of the femoral proximal end

El objetivo de este trabajo es determinar las mediciones radiológicas del extremo proximal del fémur en pacientes adultos cuyos casos fueron presentados en las discusiones clínico-radiológicas del servicio de Traumatología y Ortopedia del Hospital Central de San Cristóbal entre 2015 y 2021. Se realizó un estudio prospectivo, descriptivo, transversal, que incluyó los estudios radiológicos de cadera sana en proyección anteroposterior de pelvis centrada en pubis con rotación interna de 15 %, de 126 pacientes entre 20 y 95 años. Se midieron: ángulo cervicodiafisario, lateralización femoral, longitud y ancho del cuello femoral y diámetro de la circunferencia cefálica, mediante el sotfware MicroDicom DICOM 4.0.0. La media de ángulo cervicodiafisario fue 130,8 ± 4,5 grados, en 57 individuos (45,2 %) estuvo entre 127,4 y 133,3 grados (p = 0,001); la circunferencia cefálica media fue 42,0 ± 2,4 mm, en 60 personas (47,6 %) estuvo entre 40,2 y 45,7 mm (p = 0,001); la longitud cervical media fue 78,6 ± 16,4 mm, en 54 individuos (42,9 %) estuvo entre 69,4 y 92 mm (p = 0,001); el ancho cervical medio fue 75,9 ± 12,1 mm, en 64 casos, (50,8 %) estuvo entre 62,9 y 78,7 mm (p = 0,001). En 60 individuos (47,6 %) la lateralización del fémur estuvo entre 92,6 - 117,7 mm. Las medidas son independientes del sexo; a medida que aumenta la edad, el ángulo cervicodiafisario es menor (p= 0,021). Se realizaron tablas percentiladas de las medidas radiológicas del extremo proximal del fémur, según edad y sexo, que pueden servir de referencia en pacientes futuros(AU)

The objective of this work is to determine the radiological measurements of the proximal end of the femur in adult patients whose cases were presented in the clinical-radiological discussions of the Traumatology and Orthopedics service of the Central Hospital of San Cristóbal between 2015 and 2021. A prospective study was carried out, descriptive, crosssectional, which included radiological studies of a healthy hip in anteroposterior projection of the pelvis centered on the pubis with internal rotation of 15%, of 126 patients between 20 and 95 years of age. The following were measured: cervicodiaphyseal angle, femoral lateralization, length and width of the femoral neck, and diameter of the head circumference, using the MicroDicom DICOM 4.0.0 software. The mean neck-diaphyseal angle was 130.8 ± 4.5 degrees, in 57 individuals (45.2%) it was between 127.4 and 133.3 degrees (p = 0.001); the mean head circumference was 42.0 ± 2.4 mm, in 60 people (47.6%) it was between 40.2 and 45.7 mm (p = 0.001); the mean cervical length was 78.6 ± 16.4 mm, in 54 individuals (42.9 %) it was between 69.4 and 92 mm (p = 0.001); the mean cervical width was 75.9 ± 12.1 mm, in 64 cases (50.8%) it was between 62.9 and 78.7 mm (p= 0.001). In 60 individuals (47.6%), the lateralization of the femur was between 92.6 - 117.7 mm. The measurements are independent of sex; as age increases, the cervical shaft angle is less (p= 0.021). Percentage tables of the radiological measurements of the proximal end of the femur were made, according to age and sex, which can serve as a reference in future patients(AU)

No Más Fracturas - Implementación de la primera Unidad de Coordinación de Fracturas en Chile: experiencia al año de funcionamiento / Implementation of a fracture liaison service. Experience with 177 patients

BACKGROUND: Every year about 9 million fragility fractures (FF) occur worldwide and 80% of these are underdiagnosed or undertreated. Aiming to close the gap of diagnosis and treatment of osteoporosis, Fracture Liaison Services (FLS) were developed. AIM: To describe the implementation of the first FLS in Chile, its inclusion criteria, patient enrolment, treatment adherence and referrals during the first year. MATERIAL AND METHODS: A FLS was implemented at a health care network composed by two hospitals. The International Osteoporosis Foundation (IOF) guidelines were applied with a nurse practitioner as the coordinator. From May 2020 to April 2021 all patients diagnosed with a FF in the emergency rooms were invited to participate. Patients with pathological fractures and active cancer were excluded. Demographical data, fracture location, previous fractures, treatment and adherence, and mortality were recorded. RESULTS: From 443 patients with a diagnosis of FF, 177 patients (40%) accepted to participate. Their mean age was 74 ± 13 years and 84% (149) were female. Forty eight percent (84) had a lower extremity FF. Hip fractures were the most common (67). Ninety-five patients reported previous FF and 11,2% (20) had received anti-osteoporotic treatment. At four months of follow-up, 62% (50) had received vitamin D and calcium supplementation and 20% (16) of those patients with an indication of anti-osteoporotic drugs, had received them. CONCLUSIONS: The implementation of the FLS was successful with a 40% enrolment of patients, receiving certification by the IOF.

The Impact of Hip Fractures in the Public Health System in Brazil (SUS) 2008 - 2017: The Orthopedist Task / O impacto das fraturas do quadril no SUS 2008 - 2017: O papel do ortopedista

Abstract Objective The present study intends to describe the profile of hospitalization and ambulatory rehabilitation of patients ≥ 50 years old due to hip fracture in the Brazilian Public Health System (SUS, in the Portuguese acronym). Methods This is a cross-sectional study of patients hospitalized due to hip fracture in the SUS between 2008 and 2017. Data included 441,787 hip fracture-related hospitalizations from the hospitalization database of the department of informatics of the Brazilian Unified Health System (SIH/DATASUS, in the Portuguese acronym), and data of patients who underwent rehabilitation from the ambulatory database of the department of informatics of the Brazilian Unified Health System (SIA/DATASUS, in the Portuguese acronym.). Results Most of hip fracture-related hospitalizations (83.5%) happen to people ≥ 50 years old, with an average annual growth of 5.6% in hip fracture-related hospitalizations. The costs for the government have been growing in the same proportion and reached almost BRL 130 million in 2017, although with a 13.6% decrease in average cost per hospitalization. Besides the financial impact, hip fractures result in an in-hospital mortality rate around 5.0% in patients aged ≥ 50 years old. In addition, the percentage of patients that have undergone hip fracture-related rehabilitation increased from 2008 (14.0%) to 2012 (40.0%), and remained stable after that. Conclusions The progressive increase in the incidence of hip fractures shows the financial and social impact, and the need for immediate actions to prevent this rising trend. Hip fractures are a risk for secondary fractures, the prevention is crucial, and the orthopedist plays a central role in this process.

Resumo Objetivo O presente estudo tem como objetivo descrever o perfil de hospitalização e reabilitação ambulatorial de pacientes com idade ≥ 50 anos por fratura de quadril no Sistema Público de Saúde no Brasil (SUS). Métodos Trata-se de um estudo transversal de pacientes internados por fratura de quadril no SUS entre 2008 e 2017. Os dados incluíram 441.787 internações relacionadas à fratura de quadril do banco de dados de internação (SIH/DATASUS) e dados de pacientes submetidos à reabilitação do banco de dados ambulatorial (SIA/DATASUS). Resultados A maioria das hospitalizações relacionadas à fratura de quadril (83,5%) ocorre em pessoas ≥ 50 anos, com um crescimento médio anual de 5,6% nas hospitalizações relacionadas à fratura de quadril (HRFQ). Os custos para o governo cresceram na mesma proporção e atingiram quase 130 milhões de reais em 2017, embora com uma redução de 13,6% no custo médio por hospitalização. Além do impacto financeiro, as fraturas de quadril resultam em uma taxa de mortalidade hospitalar em torno de 5,0% em pacientes ≥ 50 anos. Além disso, o percentual de pacientes submetidos à reabilitação relacionada à fratura de quadril aumentou de 2008 (14,0%) para 2012 (40,0%) e permaneceu estável após esse período. Conclusões O aumento progressivo da incidência de fraturas de quadril mostra o impacto financeiro e social e a necessidade de ações imediatas para evitar essa tendência crescente. As fraturas de quadril são um risco para fraturas secundárias, a prevenção é crucial e o ortopedista desempenha um papel central nesse processo.

Cemented Calcar Replacement versus Long Stem Cemented Hemiarthroplasty in Unstable Intertrochanteric Fractures in Octogenarians / Substituição do calcar cimentado versus hemiartroplastia de haste longa cimentada em fraturas intertrocantéricas instáveis em octogenários

Abstract Objective The aim of the present study was to compare functional results after Cemented Calcar replacement vis-a-vis Long stem Cemented hemiarthroplasty in patients aged more than 80 years with unstable intertrochanteric fractures. Methods The present prospective, randomized trial included 140 patients with AO/OTA type 31-A2, A3 intertrochanteric femur fracture, randomized into 2 treatment groups and followed-up for a minimum of 2 years. Sixty-seven patients in group A were treated with a cemented calcar replacing prosthesis, and 65 patients in group B were treated with a cemented long stem femoral stem prosthesis. The primary end points were hip functions at 2 years. The secondary end points were the complications encountered, mortality, surgical time, reoperation, blood loss, and activities of daily living. Results There were no major differences between the groups in terms of hip function, quality of life (health related), reoperation, mortality, and blood loss. However, the function in hip joint and activities of daily living deteriorated in both groups in comparison with prefracture levels. Conclusion In octogenarians with an unstable intertrochanteric fracture, cemented calcar replacing prosthesis has similar clinical results in comparison with long stem cemented hemiarthroplasty. Hemiarthroplasty with either implant is a good option in this subset of patients. Level of evidence: I

Resumo Objetivo O objetivo do presente estudo foi comparar os resultados funcionais após a substituição do Calcar cimentado em comparação com a hemiartroplastia cimentada de haste longa em pacientes com mais de 80 anos com fratura intertrocantérica instável. Métodos O presente estudo prospectivo e randomizado incluiu 140 pacientes com fratura de fêmur intertrocantérica, conforme classificação AO/OTA tipo 31-A2, A3, randomizados em 2 grupos de tratamento e acompanhados por um período mínimo de 2 anos. Sessenta e sete pacientes do grupo A foram tratados com uma prótese de substituição do calcar cimentada e 65 pacientes do grupo B foram tratados com uma prótese femoral de haste longa cimentada. Os desfechos primários foram as funções do quadril em 2 anos. Os eventos secundários foram as complicações encontradas, a mortalidade, o tempo cirúrgico, segunda cirurgia, perda de sangue e as atividades do cotidiano. Resultados Não houve grandes diferenças entre os grupos em termos de função do quadril, qualidade de vida (relacionada à saúde), segunda cirurgia, mortalidade e perda de sangue. No entanto, a função da articulação do quadril e as atividades da vida diária se deterioraram em ambos os grupos em comparação com os níveis pré-fratura. Conclusão Nos octogenários com fratura intertrocantérica instável, a prótese de substituição do calcar cimentada apresentou resultados clínicos semelhantes em comparação com a hemiartroplastia de haste longa cimentada. A hemiartroplastia comqualquer umdos implantes é uma boa opção nesse subgrupo de pacientes. Nível de evidência: I

Intracapsular Femoral Neck Fractures in the Elderly / Fraturas intracapsulares do colo femoral no idoso

Abstract Currently, intracapsular femoral neck fracture (IFNF) is still a great challenge for orthopedists. In spite of the progress that has been made, a high mortality rate persists in the first year, especially in Brazil, where there is no awareness that such fractures in elderly patients should be treated as amedical emergency. The present article seeks to provide an update on the preoperative, surgical, and postoperative approaches.

Resumo Atualmente, a fratura intracapsular do colo femoral (FICF) ainda é um grande desafio para os ortopedistas. Apesar dos grandes avanços feitos, persiste uma grande taxa de mortalidade no primeiro ano, sobretudo no Brasil, onde não há uma conscientização de que tais fraturas nos pacientes idosos devemser tratadas como uma urgênciamédica. O presente artigo busca fornecer uma atualização das condutas pré-operatórias, cirúrgicas e pós-operatórias.

Evaluation of the Intraobserver and Interobserver Agreements of the New AO/OTA Classification for Fractures of the Trochanteric Region and the Femoral Neck / Avaliação das concordâncias intra e interobservadores da nova classificação AO/OTA para fraturas da região trocantérica e do colo do fêmur

Abstract Objective In the present study, we investigated the intra and interobserver agreement of the new Arbeitsgemeinschaft für Osteosynthesefragen/Orthopaedic Trauma Association (AO/OTA) classification for fractures of the proximal extremity of the femur. Methods One hundred hip radiographs were selected from patients who suffered fractures of the trochanteric region or femoral neck. Four orthopedists, fellowship trained hip surgeons, and four orthopedic residents evaluated and classified fractures according to the new AO/OTA system on two separate occasions. The kappa (k) coefficient was used to evaluate intra and interobserver agreement in the different steps of the classification, namely: type, group, subgroup, and qualifier. Results Hip surgery experts obtained almost perfect intraobserver agreement of type, substantial for group and, only moderate, for subgroup and qualifiers. The residents had lower performance, with substantial agreement for type, moderate for group, and reasonable for subgroup and qualifier. In the specialists' interobserver evaluation, there was also a gradual decrease in the agreement between type (almost perfect) and group (moderate), which was even lower for subgroup and qualifiers. Residents had a substantial interobserver agreement for type, moderate for group, and reasonable in the other branches. Conclusion The new AO/OTA classification for fractures of the trochanteric region and femoral neck showed intra and interobserver agreements considered appropriate for type and group, with a drop in the subsequent branches, that is, for subgroup and qualifier. Still, in relation to the old AO/OTA classification, there was an improvement in the agreements for subgroup.

Resumo Objetivo Neste estudo, investigamos a concordância intra e interobservador da nova classificação Arbeitsgemeinschaft für Osteosynthesefragen/Orthopaedic Trauma Association (AO/OTA) para fraturas da extremidade proximal do fêmur. Métodos Foram selecionadas 100 radiografias do quadril de pacientes que sofreram fraturas da região trocantérica ou do colo do fêmur. Quatro ortopedistas cirurgiões de quadril e quatro residentes de ortopedia e traumatologia avaliaram e classificaram as fraturas segundo o novo sistema AO/OTA em duas ocasiões distintas. O coeficiente de kappa (k) foi utilizado para avaliar a concordância intra e interobservadores nos diferentes passos da classificação, a saber: tipo, grupo, subgrupo e qualificador. Resultados Especialistas em cirurgia do quadril obtiveram concordância intraobservador quase perfeita de tipo, substancial para grupo e, apenas moderada para subgrupo e qualificadores. Os residentes tiveram desempenho inferior, com concordância substancial para o tipo, moderada para o grupo, e razoável para o subgrupo e qualificador. Na avaliação interobservadores dos especialistas, também se observou queda gradual da concordância entre tipo (quase perfeita) e grupo (moderada), que se mostrou ainda menor parasubgrupo e qualificadores.Residentestiveramumaconcordânciainterobservadoressubstancialparatipo, moderada para grupo e razoável nas demais ramificações. Conclusão A Nova Classificação AO/OTA para fraturas da região trocantérica e do colo do fêmur mostrou concordâncias intra e interobservadores consideradas adequadas para tipo e grupo com queda nas ramificações subsequentes ou seja para subgrupo e qualificador. Ainda assim em relação à classificação AO/OTA antiga houve melhora nas concordâncias para subgrupo.

Fixation of Intertrochanteric Fractures with Dynamic Hip Screws: Randomized Controlled Trial Comparing Hardinge and Minimally Invasive Approaches / Fraturas intertrocantéricas fixadas com parafuso dinâmico de quadril: Ensaio clínico randomizado comparando a via lateral de Hardinge e o acesso minimamente invasivo

Abstract Objective To compare the techniques for the osteosynthesis of intertrochanteric fractures with dynamic hip screws (DHSs) through the Hardinge and minimally-invasive access routes of the hip, evaluating the operative time, the degree of pain in the immediate postoperative period, the hematimetric loss, and the functional aspects of active mobility. Methods A randomized, double-blinded clinical trial in which 66 patients with intertrochanteric fractures were submitted to osteosynthesis by DHS. The patients were divided into a test group, submitted to the minimally-invasive access, and a control group, in whom the surgery was performed through the Hardinge route. Results Patients submitted to the minimally-invasive treatment presented a lower degree of postoperative pain compared to the group treated by the Hardinge lateral route (p< 0.001), as well as lower hematimetric loss (p< 0.001), shorter operative time (p< 0.001), and improvement in immediate postoperative active mobility tests (p <0.05). Conclusion The study demonstrated the clinical superiority of the minimally-invasive access route parameters analyzed in relation to the Hardinge access for the fixation of intertrochanteric fractures when DHS is the choice osteosynthesis method. Level of evidence I.

Resumo Objetivo Comparar as técnicas de osteossíntese de fraturas intertrocantéricas com o parafuso dinâmico de quadril (dynamic hip screw, DHS, em inglês) pelas vias de acesso de Hardinge e minimamente invasiva do quadril, avaliando o tempo cirúrgico, o grau de dor no pós-operatório imediato, a perda hematimétrica, e os aspectos funcionais de mobilidade ativa. Métodos Estudo clínico randomizado e duplo-cego, em que 66 pacientes com fratura intertrocantérica foram submetidos a osteossíntese com DHS. Os pacientes foram divididos em um grupo teste, submetidos ao acesso minimamente invasivo, e um controle, em que a cirurgia foi realizada pela via de Hardinge. Resultados Os pacientes submetidos ao tratamento pela via minimamente invasiva apresentaram um grau de dor pós-operatória inferior em comparação ao grupo tratado pela via lateral de Hardinge (p< 0,001), assim como menor perda hematimétrica (p< 0,001), menor tempo operatório (p< 0,001), e melhora nos testes de mobilidade ativa pós-operatória imediata (p< 0,05). Conclusão O estudo demonstrou a superioridade clínica nos parâmetros analisados da via de acesso minimamente invasiva em relação ao acesso de Hardinge para a fixação de fraturas intertrocantéricas, quando o DHS for a opção de osteossíntese escolhida. Nível de evidência I.

Abstract Objective To assess the impact of the multidisciplinary co-management program on the outcomes of hospitalized patients with hip fractures. Methods This is an observational, before-and-after, retrospective study. Data were collected from patients hospitalized for hip fracture between 2015 and 2019, at a university hospital with a referral service for orthopedics. The intervention analyzed was the multidisciplinary co-management program, which started in 2017. Results The number of pressure injuries acquired during hospitalization decreased significantly (p<0.005) after the implementation of co-management. Likewise, the length of hospital stay until surgery was reduced (p<0.046), and national and international guidelines for fracture correction within 48 hours were complied with. Infections, readmissions and deaths have not had their impact confirmed. Conclusion The multidisciplinary co-management had a positive impact on the outcomes of patients hospitalized for hip fracture, resulting in a reduction in the number of pressure injuries and in the waiting time for surgery. Through this study, preliminary evidence was identified to support the implementation of this type of program.

Psychometric properties of the Chinese version of the Positive Thinking Scale in individuals after hip fracture surgery

Positive thinking is a form of positive cognition and a coping strategy. The Positive Thinking Scale (PTS) is used to measure positive thinking, but the reliability and validity of the PTS-Chinese have yet to be tested. This study aims to examine the psychometric properties of the PTS-Chinese. A total of 154 patients post-hip fracture surgery completed the questionnaire in a hospital in Taiwan between April 2020 and December 2020. The scales in the questionnaire included the PTS, Automatic Thoughts Questionnaire-Positive, Automatic Thoughts Questionnaire-Negative, Barthel Index, and items related to happiness, demographics, and disease treatment. The results of the confirmatory factor analysis and average variance extracted show that the PTS-Chinese version exhibits construct validity. Scores on the PTS-Chinese version are positively related to scores on the Automatic Thoughts Questionnaire-Positive and happiness items and negatively related to scores on the Automatic Thoughts Questionnaire-Negative. This finding indicates that the PTS-Chinese demonstrates concurrent, predictive, and discriminant validity. The scale also presents acceptable reliability and test-retest reliability. Overall, the PTS-Chinese can be used to evaluate and track the positive thinking of patients. Further studies are needed to assess the psychometric properties of the PTS-Chinese in different cultures and ethnic groups. (AU)
