Comparison between arthroscopic Bankart repair versus arthroscopic Bankart/SLAP lesion repair in limited-contact athletes with type V SLAP lesion. A prospective cohort study.

PURPOSE: The aim of this study was to compare the functional outcomes, recurrence rate, range of motion (ROM) and return to sports activities between arthroscopic Bankart repair (ABR) versus arthroscopic Bankart/SLAP repair (ABR/S) in limited contact-athletes with a type V SLAP lesion in the scenario of recurrent anterior shoulder instability (RASI). Our hypothesis was that there is no difference between the two treatments. METHODS: Two groups of 45 limited-contact athletes with type V SLAP lesion were created. Group 1 underwent an arthroscopic Bankart repair, while group 2 had an arthroscopic Bankart/SLAP repair. The minimum follow-up period was 2 years. The WOSI and ASES scores were used to assess primary functional outcomes. Recurrence rate, ROM and return to sport were also evaluated. RESULTS: Significant differences were reported in the WOSI and ASES scores pre- and post-operatively in each group. There were no significant differences between the two groups (P = 0.78 and 0.43). We reported 4 recurrences (8.8 %) in group 1 and 5 (11.1 %) in group 2, with no difference between them (P = 0.62). There were no significant differences between the range of motion of each of the groups as well as between them. More than 90% of the athletes in both groups returned to their previous sporting activities. CONCLUSIONS: Limited-contact athletes with RASI who have a type V SLAP lesion as their primary diagnosis can be treated using either ABR or ABR/S with equal efficacy. Both treatment alternatives preserve athlete's function, stability, ROM and return to sport.

Shoulder injuries in Brazilian professional football players: epidemiological analysis of 3828 games.

OBJECTIVES: Football is a globally played sport that poses potential risks for musculoskeletal injuries. Upper-limb injuries have a lower incidence rate than lower-limb injuries but can still cause absenteeism and performance impairment in football players. This descriptive epidemiological study aimed to evaluate and compare the epidemiological data on shoulder injuries among professional football players in two major Brazilian football championships. METHODS: Data were collected throughout the championships, and club physicians medically evaluated each player during official games using two online forms. The collected information included the player's age and position, injury diagnosis, laterality, location on the field where the injury occurred, playing time, imaging examinations performed, need for surgical treatment, time to return to play (TRP), and recurrence of the injury. The incidence of injuries was evaluated using the Federation Internationale de Football Association (FIFA) incidence formula. RESULTS: A total of 107 shoulder injuries were recorded (4.3% of all injuries), with a FIFA incidence of 0.847. Glenohumeral dislocations (GHDs) and acromioclavicular dislocations (ACDs) accounted for 37.38% and 35.51% of all shoulder injuries, respectively. Goalkeepers and defenders presented, respectively, a 2.15 and 1.57 times increased risk of suffering shoulder injuries, while attackers presented a 0.63 times decreased risk. Injury recurrence was observed in 14.95% of cases, with GHDs and ACDs showing recurrence rates of 35.00% and 5.26%, respectively. Surgery was performed in 9.35% of cases, with GHDs representing 50% of all surgeries. The average TRP was 22.37 days, with severe and major injuries accounting for 11.21% and 10.28% of all injuries, respectively. Goalkeepers had the highest average TRP of 36.15 days. Recurring injuries had a higher average TRP of 33.44 days compared to nonrecurring injuries, which had an average TRP of 20.43 days. Surgically treated injuries had the highest average TRP of 112.5 days. CONCLUSION: Shoulder injuries in the professional football scenario are of great concern due to the high recurrence rate and need for surgical treatment, which will lead to a long TRP. These findings emphasize the need to implement prevention protocols and effective treatments to reduce the consequences of such injuries, which are usually underestimated in this sport. LEVEL OF EVIDENCE: III.

Tríada terrible de hombro: reporte de un caso / Terrible triad of the shoulder. Case report

La luxación glenohumeral (GH) anteroinferior del hombro es una patología frecuente en la emergencia de hospitales, viene precedida de un evento traumático y está acompañada de una avulsión labral conocida como Bankart y una fractura posterolateral de la cabeza humeral denominada "lesión de Hill­Sachs". Cuando la luxación GH se asocia a una rotura del manguito rotador o fractura de tuberosidades humerales y lesión neurológica del plexo braquial se conoce como tríada terrible del hombro.Se describe el caso de una paciente que acude a emergencias con trauma agudo de hombro derecho, se corroboró la presencia de luxación glenohumeral anterior con fractura avulsión de la tuberosidad mayor con exámenes complementarios y no se diagnosticó la lesión del nervio axilar hasta después de la primera consulta en nuestro centro. La luxación fue reducida bajo anestesia en emergencia y posteriormente la lesión del manguito rotador se trató con suturas transóseas y asistencia artroscópica; la paciente presentó compromiso del nervio axilar o circunflejo que se diagnosticó clínicamente en nuestra primera valoración con el protocolo A.R.A.R.A.I. (A: anestesia cara lateral del brazo (dermatoma del axilar). R: radiografía AP verdadera y perfil escapular. A: anestesia para su reducción. R: reducción con la maniobra de elección del cirujano. A: axilar comparativas. Radiografías para evidenciar si existe compromiso óseo de la lesión de Bankart. I: inmovilización) y se comprobó que se trataba de neuropraxia con electromiografía, por lo que se resolvió espontáneamente con medicación y fisioterapia. Por lo tanto, se recomienda a todo paciente con trauma de hombro que asiste a emergencia iniciar con la valoración neurológica, si esta pasa desapercibida podría convertirse en una secuela para el paciente, o un problema legal para el médico tratante.

Anteroinferior Glenohumeral (GH) dislocation of the shoulder is a common pathology in emergencies rooms. It is preceded by a traumatic event and is accompanied by a labral avulsion known as Bankart and a posterolateral fracture of the humeral head known as Hill-Sachs lesion. When GH dislocation is accompanied by rotator cuff tear or fracture of humeral tuberosities and neurological injury to the brachial plexus, it is known as terrible shoulder triad.We describe the case of a patient who came to the emergency room with acute trauma to the right shoulder. The presence of anterior glenohumeral dislocation with avulsion fracture of the greater tuberosity was confirmed with complementary examinations and the axillary nerve injury was not diagnosed until after surgery first visit at our center. The dislocation was reduced under anesthesia and the rotator cuff injury was subsequently treated with trans-osseous sutures and arthroscopic assistance. The patient presented involvement of the axillary or circumflex nerve that was diagnosed clinically in our first evaluation with the A.R.A.R.A.I. protocol and was proven to be neuropraxia with electromyography, so it resolved spontaneously with medication and physiotherapy. Therefore, every patient with shoulder trauma who attends the emergency room is recommended to start with a neurological assessment; if this goes unnoticed, it could become a sequela for the patient or a legal problem for the physicians.

Return to Sports Following Shoulder Injury: Clinical Evaluation, Isokinetic, and Functional Testing.

ABSTRACT: The shoulder is commonly injured in overhead sports. This is associated with a high degree of mobility at the expense of stability, sports specific demands, high volume or intensity of practice and competition, biomechanical deficits, and poor technique. Following injury, the return to competition process includes nonsurgical or surgical treatment, comprehensive rehabilitation, and a structured return to sports program. The return to sports continuum is divided into phases which include return to practice of the sport, return to competition at a lower level or with reduced performance, and return to expected performance. Components of the return to sports decision include clinical evaluation of physical and psychological readiness, measurement of muscle strength using isokinetic tests, evaluation of overhead functional tasks, and progression in a supervised interval throwing program. The evidence for the effectiveness of return to sports programs following shoulder injury is limited but evolving and is an area that will merit continued investigation.

Condutas cinesioterapêuticas no tratamento das tendinopatias do manguito rotador em atletas de voleibol de quadra / Kinesiotherapeutic conducts in the treatment of rotator cuff tendinopathies in indoor volleyball athletes

Introdução: o ombro do jogador de voleibol é suscetível a lesões resultantes de sobrecargas biomecânicas e movimentos repetitivos. As frequentes queixas de dor nessa articulação evidenciam o elevado volume de ações motoras unilaterais em alta velocidade acima da cabeça, atingindo o manguito rotador (MR) e gerando limitação funcional na prática desportiva. As tendinopatias do MR, formado pelos músculos subescapular, redondo menor, infraespinhal e supraespinhal, atingem comumente os tendões do supraespinhal e do infraespinhal. Objetivo: descrever as condutas cinesioterapêuticas utilizadas no tratamento das tendinopatias do MR em atletas de voleibol de quadra. Metodologia: pesquisaram-se as bases de dados MEDLINE, SciELO e BVS. Descritores: lesões do ombro, manguito rotador, atletas, voleibol e Terapia por Exercício (pesquisados em inglês), associados dois a dois ou três a três, dentre os quais o termo atletas ou voleibol sempre foi mantido. Foram incluídos artigos de revisão, artigos originais, ensaios clínicos e estudos de coorte publicados em português e inglês, entre os anos de 2009 e 2019. Resultados: inicialmente a busca resultou em 480 artigos. Após o processo de seleção, seis estudos foram revisados na íntegra e incluídos na síntese qualitativa. Conclusão: as principais condutas cinesioterapêuticas descritas foram: fortalecimento dos rotadores externos, dos músculos do tronco, da coluna e periescapulares, alongamento da região posterior do ombro e mobilizações articulares.

Introduction: the volleyball player's shoulder is susceptible to injuries resulting from biomechanical overloads and repetitive movements. The frequent complaints of pain in this joint highlight the high volume of unilateral motor actions at high speed above the head, reaching the rotator cuff (RC) and generating functional limitation in sports. RC tendinopathies, formed by the subscapularis, teres minor, infraspinatus and supraspinatus muscles, commonly affect the supraspinatus and infraspinatus tendons. Objective: to describe the kinesiotherapeutic conducts used in the treatment of RC tendinopathies in indoor volleyball athletes. Methodology: MEDLINE, SciELO and VHL databases were searched. Descriptors: shoulder injuries, rotator cuff, athletes, volleyball and Exercise Therapy (searched in English), associated two by two or three by three, among which the term athletes or volleyball was always maintained. Review articles, original articles, clinical trials and cohort studies published in Portuguese and English between 2009 and 2019 were included. Results: initially the search resulted in 480 articles. After the selection process, six studies were fully reviewed and included in the qualitative synthesis. Conclusion: the main kinesiotherapeutic procedures described were strengthening of the external rotators, trunk, spine and periscapular muscles, stretching of the posterior region of the shoulder and joint mobilizations.

Effects of elastic kinesiology taping on shoulder proprioception: a systematic review.

BACKGROUND: Shoulder injuries are associated with proprioceptive deficits. Elastic kinesiology tape (KT) is used for treating musculoskeletal disorders, including shoulder injuries, as it arguably improves proprioception. OBJECTIVE: To synthesize the evidence on the effects of elastic KT on proprioception in healthy and pathological shoulders. METHODS: Four databases (PubMed, WoS, CINAHL, SPORTDiscus) were searched for studies that investigated the effects of elastic KT on shoulder proprioception. Outcome measures were active joint position sense (AJPS), passive joint position sense (PJPS), kinesthesia, sense of force (SoF), and sense of velocity (SoV). Risk of bias (RoB) was assessed using the Cochrane Collaboration RoB tool for randomized controlled trials (RCTs), and the ROBINS-1 for non-RCTs, while the certainty of evidence was determined using GRADE. RESULTS: Eight studies (5 RCTs, 3 non-RCTs) were included, yielding 187 shoulders (102 healthy and 85 pathological shoulders). RoB ranged from low (2 studies), moderate (5 studies), to high (1 study). Elastic KT has a mixed effect on AJPS of healthy shoulders (n=79) (low certainty). Elastic KT improves AJPS (subacromial pain syndrome and rotator cuff tendinopathy, n=52) and PJPS (chronic hemiparetic shoulders, n=13) among pathological shoulders (very low certainty). Elastic KT has no effect on kinesthesia among individuals with subacromial pain syndrome (n=30) (very low certainty). CONCLUSION: There is very low to low certainty of evidence that elastic KT enhances shoulder AJPS and PJPS. The aggregate of evidence is currently so low that any recommendation on the effectiveness of elastic KT on shoulder proprioception remains speculative.

Magnetic resonance arthrographic demonstration of extension of labral defects in paraglenoid labral cysts.

OBJECTIVE: This study aimed to investigate the extension of labral tears associated with paraglenoid labral cysts by magnetic resonance arthrography. METHODS: The magnetic resonance and magnetic resonance arthrography images of patients with paraglenoid labral cysts who presented to our clinic between 2016 and 2018 were examined. In patients with paraglenoid labral cysts, the location of the cysts, the relation between the cyst and the labrum, the location and extent of glenoid labrum damage, and whether there was contrast medium passage into the cysts were investigated. The accuracy of magnetic resonance arthrographic information was evaluated in patients undergoing arthroscopy. RESULTS: In this prospective study, a paraglenoid labral cyst was detected in 20 patients. In 16 patients, there was a defect in the labrum adjacent to the cyst. Seven of these cysts were adjacent to the posterior superior labrum. In 13 patients, there were contrast solution leak into the cyst. For the remaining seven patients, no contrast-medium passage was observed in the cyst. Three patients had sublabral recess anomalies. Two patients had rotator cuff muscle denervation atrophy accompanying the cysts. The cysts of these patients were larger compared to those of the other patients. CONCLUSION: Paraglenoid labral cysts are frequently associated with the rupture of the adjacent labrum. In these patients, symptoms are generally accompanied by secondary labral pathologies. Magnetic resonance arthrography can be successfully used not only to demonstrate the association of the cyst with the joint capsule and labrum, but also to reliably demonstrate the presence and extension of labral defects.

Shoulder Injury Related to Vaccine Administration: Case Series / Lesão de ombro relacionada à administração de vacina: Série de casos

Abstract Objective Shoulder pain is a common presentation in the primary care setting, and shoulder pain after vaccination has a growing body of literature. The present study sought to understand how a standardized treatment protocol would aid patients experiencing shoulder injury related to vaccine administration (SIRVA). Methods Patients experiencing SIRVA were retrospectively recruited between February 2017 and February 2021. All patients were treated with physical therapy and offered a cortisone injection. Post-treatment range of motion (i.e., forward elevation, external rotation, internal rotation) and patients' reported outcomes were collected with the visual analogue scale (VAS), American Shoulder and Elbow Surgeons (ASES), simple shoulder test (SST), and single assessment numeric evaluation (SANE) scores. Results A total of 9 patients were retrospectively examined. Among them, 6 patients presented within one month of a recent vaccination event, while 3 patients presented 67, 87, and 120 days after vaccination. Furthermore, 8 of the patients completed physical therapy, and 6 of them underwent a cortisone injection. The follow-up time averaged 8 months. At final follow-up, the mean external rotation was 61º (standard deviation, SD±3º) and the mean forward elevation was 179º (SD±45º). Internal rotation ranged between L3 and T10. The VAS pain scores were 3.5/10.0 (SD±2.4), the mean ASES score was 63.5/100.0 (SD±26.3), and the SST scores were 8.5/12.0 (SD±3.9). Finally, the SANE scores were 75.7/100.0 (SD±24.7) and 95.7/100.0 (SD±6.1) in the injured and contralateral shoulders respectively. Conclusion Shoulder pain after a vaccination treated with physical therapy and cortisone injection ultimately resulted in favorable shoulder range of motion and functional score outcomes. Level of Evidence IV

Resumo Objetivo A dor no ombro é um quadro comum na atenção primária e há cada vez mais relatos acerca de sua ocorrência após a vacinação. Este estudo buscou entender como um protocolo de tratamento padronizado ajudaria pacientes com lesão no ombro relacionada à administração de vacina (SIRVA). Métodos Os pacientes com SIRVA foram recrutados de forma retrospectiva entre fevereiro de 2017 e fevereiro de 2021. Todos os pacientes foram submetidos à fisioterapia e receberam uma prescrição de cortisona injetável. A amplitude de movimento pós-tratamento (ou seja, elevação anterior, rotação externa, rotação interna) e os desfechos relatados pelo paciente foram analisados a partir das pontuações da escala visual análoga (EVA), da American Shoulder and Elbow Surgeons (ASES), do teste simples do ombro (SST) e da avaliação numérica única (SANE). Resultados No total, 9 pacientes foram examinados de maneira retrospectiva. Entre eles, 6 pacientes foram atendidos no primeiro mês após a vacinação e os outros três, depois de 67, 87 e 120 dias. Ademais, 8 dos pacientes fizeram todo o tratamento fisioterápico e 6 receberam uma injeção de cortisona. O período médio de acompanhamento foi de 8 meses. À última consulta, a rotação externa média foi de 61° (desvio padrão, DP±3°)ea elevação anterior média foi de 179° (DP ± 45°). A rotação interna variou entre L3 e T10. As pontuações de dor à EVA foram de 3,5/10,0 (DP ± 2,4) e o escore médio ASES foi de 63,5/100,0 (DP ± 26,3); as pontuações de SST foram 8,5/12,0 (DP ± 3,9). Por fim, os escores de SANE foram de 75,7/100,0 (DP ± 24,7) e 95,7/100,0 (DP ± 6,1) nos ombros lesionados e contralaterais, respectivamente. Conclusão A dor no ombro após a vacinação tratada com fisioterapia e injeção de cortisona melhorou a amplitude de movimento e os escores funcionais. Nível de Evidência IV

Acromioclavicular Joint Injuries in Sport.

ABSTRACT: Sport-related shoulder injuries, including disruptions to the acromioclavicular joint (ACJ), are common. An ACJ injury is classified by the degree and direction of the clavicle displacement. Although the diagnosis can be made clinically, standard radiographic views are important to determine the severity of the ACJ disruption and assess for concurrent injuries. The majority of ACJ injuries can be managed nonoperatively; however, surgical treatment is indicated in some cases. Long-term outcomes are generally favorable for most ACJ injuries, and athletes generally return to sport without functional limitations. This article provides an in-depth discussion regarding all aspects of ACJ injuries, including clinically relevant anatomy, biomechanics, evaluation, treatment, and complications.

Association of trunk and lower limb factors with shoulder complaints and sport performance in overhead athletes: A systematic review including GRADE recommendations and meta-analysis.

OBJECTIVE: To identify the association of trunk and lower limb factors with shoulder complaints and sport performance in overhead athletes. METHODS: Search performed at PubMed/Medline, Embase, CINAHL, LILACS, Cochrane, Web of Science and SPORTDiscus for observational studies. Methodological quality and strength of the evidence was assessed with the Newcastle-Ottawa Scale and GRADE. Meta-analysis and effects sizes analysis were calculated when possible. RESULTS: Sixty-five studies were included. Low to very-low evidence suggests no association of trunk/lower limb strength, endurance, power, jump or balance with shoulder complaints and/or throwing performance. Athletes with shoulder complaints performed worse in trunk stability and endurance tests (mean difference: -6.83 (95%CI: -8.78, -4.88)). Athletes with high throwing performance presented better results in CMJ, horizontal jump, power measures and knee extension strength. For swimmers, there was no association of trunk/lower limb endurance with shoulder complaints (moderate evidence) and no association of balance and swimming performance (low evidence). Better trunk/lower limb strength, power and vertical jumps measures were associated with better swimming performance. CONCLUSIONS: In methodologically similar studies, some trunk/lower limb outcomes are associated with shoulder complaint or sport/swimming performance. Results should be considered with caution and future studies should use better methodologies.

Are Previous Joint Injuries Associated with Muscle Performance in Volleyball Athletes? / Lesões articulares prévias são associadas ao desempenho muscular de jogadores de voleibol?

Abstract Objective The aim of the present study is to determine whether previous shoulder and knee injuries were associated with isokinetic fatigue index and agonist/antagonist ratio of shoulder internal/external rotators and knee flexors/extensors in male volleyball athletes. Methods The current study is a cross-sectional investigation of 49 male elite volleyball players competing at a high level in Brazil. Isokinetic fatigue index and agonist/antagonist profiles were assessed during the preseason. Additionally, in order to record previous injuries, the athletes answered a standardized questionnaire. We conducted a receiver operating characteristic (ROC) curve analysis to determine the association strength and the clinically relevant cut-off point for variables presenting statistical significance for the area under the curve (AUC) (α = 0.05). An independent t-test was used to compare isokinetic variables between athletes with and without previous injury (α = 0.05). Results The results of the ROC curve analysis indicated that hamstring fatigue index values at 300o/s were associated with the presence of previous knee injury (area under the curve [AUC] = 73%, p= 0.004), and shoulder external rotators fatigue index values at 360°/s were not associated with the presence of previous shoulder injury (AUC = 68%, p= 0.053). Conclusions Elite volleyball athletes who reported previous knee injuries were prone to a higher fatigue index than those reporting no injuries. Knee flexor resistance training might be useful for those athletes who reported knee injuries in the previous season.

Resumo Objetivo O objetivo deste estudo é determinar se lesões prévias de ombro e joelho estavam associadas ao índice de fadiga isocinética e razão agonista/antagonista dos rotadores internos/externos do ombro e flexores/extensores do joelho em jogadores de voleibol. Métodos Esta é uma investigação transversal com 49 jogadores de voleibol de elite que competem em alto nível no Brasil. O índice de fadiga isocinética e os perfis de agonistas/antagonistas foram avaliados durante a pré-temporada. Além disso, para registro de lesões anteriores, os atletas responderam a um questionário padronizado. Conduzimos uma análise da curva de característica de operação do receptor (receiver operating characteristic, ROC) para determinar a força de associação e o ponto de corte clinicamente relevante de variáveis com significância estatística na área sob a curva (AUC) (α = 0,05). Um teste t independente comparou as variáveis isocinéticas entre atletas com e sem lesão prévia (α = 0,05). Resultados Os resultados da análise da curva ROC indicam que os valores do índice de fadiga dos isquiotibiais a 300o/s foram associados à presença de lesão prévia no joelho (área soba a curva [AUC] = 73%, p= 0,004), enquanto os valores do índice de fadiga dos rotadores externos do ombro a 360°/s não foram associados à presença de lesão prévia no ombro (AUC = 68%, p= 0.053). Conclusões Atletas de voleibol de elite que relataram lesões anteriores no joelho estavam propensos a um índice de fadiga maior do que aqueles que não relataram lesões. O treinamento de resistência de flexores do joelho pode ser útil para atletas com relatos de lesões no joelho na temporada anterior.

Intrinsic Risk Factors for Noncontact Musculoskeletal Injury in Collegiate Swimmers: A Prospective Cohort Study.

CONTEXT: Shoulder pain is pervasive in swimmers of all ages. However, given the limited number of prospective studies, injury risk factors in swimmers remain uncertain. OBJECTIVE: To determine the extent to which the risk factors of previous injury, poor movement competency, erroneous freestyle swimming technique, and low perceived susceptibility to sport injury were associated with noncontact musculoskeletal injury in collegiate swimmers. DESIGN: Prospective cohort study. SETTING: College natatorium. PATIENTS OR OTHER PARTICIPANTS: Thirty-seven National College Athletic Association Division III swimmers (21 females, 16 males; median age = 19 years [interquartile range = 3 years], height = 175 ± 10 cm; mass = 70.0 ± 10.9 kg). MAIN OUTCOME MEASURE(S): Participants completed preseason questionnaires on their previous injuries and perceived susceptibility to sport injury. At the beginning of the season, they completed the Movement System Screening Tool and the Freestyle Swimming Technique Assessment. Logistic regression was used to calculate odds ratios (ORs) with 95% CIs for the association between each risk factor and injury. RESULTS: Eleven of the 37 participants (29.7%) sustained an injury. Univariate analyses identified 2 risk factors: previous injury (OR = 8.89 [95% CI = 1.78, 44.48]) and crossover hand positions during the freestyle entry phase (OR = 8.50 [95% CI = 1.50, 48.05]). After adjusting for previous injury, we found that a higher perceived percentage chance of injury (1 item from the Perceived Susceptibility to Sport Injury) decreased the injury odds (adjusted OR = 0.11 [95% CI = 0.02, 0.82]). Poor movement competency was not associated with injury (P > .05). CONCLUSIONS: Previous injury, a crossover hand-entry position in freestyle, and a low perceived percentage chance of injury were associated with increased injury odds. Ascertaining injury histories and assessing for crossover positions may help identify swimmers with an elevated injury risk and inform injury-prevention strategies.

Reparación sistemática del manguito rotador: Clasificación de la Fundación Santa Fe de Bogotá / Standardized rotator cuff repair. Classification of Fundación Santa Fe de Bogotá

La cirugía de manguito rotador se ha popularizado en los últimos años y pasó de realizarse mediante una técnica abierta, en la mayoría de los casos, a la reparación artroscópica. Se han descrito múltiples técnicas para la fijación del hueso, pero no se han estandarizado el orden y los pasos para llevar a cabo esta reparación, lo que generó inconsistencias y heterogeneidad en los resultados de la reparación. En este artículo, se propone una nueva clasificación de las lesiones del manguito rotador que les permitirá a los cirujanos tomar decisiones durante la cirugía de reparación artroscópica del manguito rotador. Nivel de Evidencia: IV

Rotator cuff surgery has become more popular in recent years, transitioning from an open technique to arthroscopic surgery. Although multiple techniques for bone fixation have been described, the steps to perform this repair have not been standardized, leading to inconsistencies and heterogeneity in the outcomes. This article proposes a new classification of rotator cuff injuries that will help surgeons make decisions during arthroscopic rotator cuff repair surgery. Level of Evidence: IV

Estabilização de ombro em um gato ­ Relato de caso / Shoulder estabilization in a cat ­ Case report

A estabilidade da articulação do ombro é garantida por ligamentos, cápsula articular, tendões e músculos, contudo traumas podem causar falência dos mecanismos estabilizadores, com consequente luxação ou instabilidade articular. Objetivou-se relatar o caso de instabilidade medial e lateral de ombro direito em felino sem raça definida, atendido com queixa de claudicação aguda de membro torácico secundária a trauma por confronto com outro animal. Inicialmente foi realizado tratamento clínico por meio de imobilização articular. Contudo, devido ao insucesso da técnica, procedeu-se para o tratamento cirúrgico de estabilização articular com prótese ligamentar sintética. No pós-operatório imediato, evidenciou-se ausência de crepitações e instabilidade articular. Após oito dias da cirurgia, o paciente apresentou retorno total às funções de apoio do membro e sem sinais de dor ou redução de movimentos. Concluiu-se que, embora de reduzida ocorrência, a instabilidade de origem traumática do ombro configura-se como um diferencial para claudicação aguda de membro torácico e que o tratamento cirúrgico pode ser necessário, mostrando-se eficiente na resolução de tais casos com o acesso e técnica de estabilização propostos.

The stability of the shoulder joint is granted by ligaments, joint capsule, tendons and muscles. However, traumatic injuries can cause failure of the stabilization mechanisms, which leads to articular luxation or instability. The aim of the paper is to report a case of medial and lateral right shoulder joint instability in a mixed-breed cat, presenting acute forelimb lameness after a fight trauma with another cat. Initially, it was recommended a conservative treatment through articular immobilization. However, the technique was unsuccessful, and the surgery treatment was performed, to stabilize the joint with synthetic ligament prosthetic. In the postoperative period, no crepitation or instability were identified. After eight days of surgery, the patient returned totally to the normal function of the forelimb, without movement restriction or pain. It was concluded that, although rare, the traumatic shoulder joint instability is a differential diagnosis for acute forelimb lameness and the surgical treatment can be necessary, showing a good result in the resolution of these injuries with the surgical approach and stabilization method proposed.

Rotator Cuff Lesion in Wheelchair Users with Spinal Cord Injury: Does Time of Injury and Medullary Level Interfere? A Retrospective Evaluation / Lesão do manguito rotador em cadeirantes com lesão medular: O tempo de lesão e o nível medular interferem? Uma avaliação retrospectiva

Abstract Objective To describe magnetic resonance imaging (MRI) characteristics of shoulders from patients with spinal cord injury (SCI) and to correlate these findings with age, duration of SCI and neurological level. Method The study sample included patients with thoracic SCI over 18 years of age, who were active wheelchair users and had undergone an MRI of the shoulder from January 2004 to December 2015. Results We studied 41 shoulders (37 patients), including 27 men (65.9%) and 14 women (34.1%). At the time of MRI, the mean age was 41.9 years and the mean duration of SCI was 9.4 years. The analysis of the relationship between the duration of trauma and severity of the rotator cuff lesion (RCL), as well as between age and the severity of the shoulder injury showed a statistically significant difference (p< 0.001), with a positive association in both cases. No statistically significant difference (p= 0.095) was observed between the neurological level of the SCI and RCL. Conclusion In this study, a progressive increase in the severity of the shoulder lesions can be noted with advancing age and a longer duration of SCI. However, level of the SCI does not seem to interfere with RCL. Level of Evidence Level IV, case series.

Resumo Objetivo Descrever as características de ressonância magnética (RM) dos ombros de pacientes com lesão medular (LM) e correlacionar esses achados com idade, duração da LM e nível neurológico. Método A amostra do presente estudo incluiu pacientes maiores de 18 anos com LM torácica, que eram cadeirantes ativos e haviam sido submetidos a uma ressonância magnética do ombro de janeiro de 2004 a dezembro de 2015. Resultados Foram estudados 41 ombros (37 pacientes), incluindo 27 de pacientes do sexo masculino (65,9%) e 14 de pacientes do sexo feminino (34,1%). Na época da ressonância magnética, a média de idade era de 41,9 anos e a duração média da LM era de 9,4 anos. A análise da relação entre a duração do trauma e a gravidade da lesão do manguito rotador (LMR), bem como entre a idade e a gravidade da lesão do ombro mostrou diferença estatisticamente significativa (p< 0,001), com associação positiva em ambos os casos. Não foi observada diferença estatisticamente significativa (p= 0,095) entre o nível neurológico da LM e da LMR. Conclusão Neste estudo, pode-se notar um aumento progressivo da gravidade das lesões do ombro com o avanço da idade e uma maior duração da LM. No entanto, o nível da LM não parece interferir com a LMR. Nível de Evidência Nível IV, série de casos.

Results of Latissimus Dorsi Transfer using a Tendinous Allograft through a Single Deltopectoral Approach for Irreparable Posterosuperior Rotator Cuff Tears / Resultados da transferência do grande dorsal alongado com enxerto tendíneo homólogo por via delto-peitoral para lesões póstero-superiores irreparáveis do manguito rotador

Abstract Objective The primary aim of the present study is to evaluate the functional results of a modification to the latissimus dorsi (LD) transfer around the shoulder for irreparable posterosuperior rotator cuff tears. The secondary aim is to evaluate variables that might influence the outcomes. Surgical Technique Through a single deltopectoral approach, the LD tendon is detached, reinforced, and elongated with a tendinous allograft, transferred around the humerus, and fixed superolaterally to the greater tuberosity and anteriorly to the subscapularis. Methods Retrospective functional evaluation of 16 cases. The average follow-up was 21 months (12-47). The postoperative results (at last follow-up) were compared with the preoperative ones, as well as to other pre, intra, and postoperative variables. Results All (but one) patients were satisfied. Average University of California, Los Angeles (UCLA) score increased from 11.6 (8-16) to 27.3 (17-30) (p< 0.001). Improvements of shoulder pain, function, and strength achieved statistical significance (p< 0.001). Nonetheless, normal strength was never restored. Average active range of motion improved as follows: forward elevation, from 106° (60-140°) to 145° (130-160°) (p< 0.001); external rotation from 30° (0° to 60°) to 54° (40-70°) (p< 0.001); and internal rotation from L1 (gluteus to T7) to T10 (T12-T3) (p< 0.05). No complication has occurred. Preoperative pseudoparesis was reverted in all the six cases in which it was present. None of the variables analyzed influenced the outcomes, including pseudoparesis. Conclusions At early follow-up, this technique is safe and effective at recovering from pseudoparesis and at improving shoulder pain, function, and strength.

Resumo Objetivo O objetivo primário do presente trabalho é avaliar os resultados funcionais de uma modificação na transferência do grande dorsal no ombro para o tratamento de lesões póstero-superiores irreparáveis do manguito rotador. O objetivo secundário é avaliar as variáveis que podem influenciar os resultados. Técnica cirúrgica Por meio de uma única abordagem deltopeitoral, o tendão do músculo grande dorsal é desinserido reforçado e alongado com um enxerto tendíneo homólogo, transferido para o úmero e fixado em posição superolateral ao tubérculo maior e anterior ao músculo subescapular. Métodos Avaliação funcional retrospectiva de 16 casos. O período médio de acompanhamento foi de 21 meses (12-47 meses). Os resultados pós-operatórios (no último acompanhamento) foram comparados aos pré-operatórios, bem como a outras variáveis pré, intra e pós-operatórias. Resultados Todos os pacientes ficaram satisfeitos (exceto um). A pontuação média da University of California, Los Angeles (UCLA) aumentou de 11,6 (8-16) para 27,3 (17-30) (p< 0,001). A dor, a função e a força do ombro apresentaram melhora estatisticamente significativa (p< 0,001). A força, porém, não voltou ao valor normal. A amplitude de movimento ativa média apresentou as seguintes melhoras: elevação frontal, de 106° (60-140°) para 145° (130-160°) (p< 0,001); rotação externa, de 30° (0-60°) para 54° (40-70°) (p< 0,001); e rotação interna, de L1 (glúteo a T7) para T10 (T12-T3) (p< 0,05). Nenhuma complicação foi observada. A pseudoparesia pré-operatória foi revertida em todos os seis casos em que foi observada. Nenhuma das variáveis analisadas influenciou os desfechos, nem mesmo a pseudoparesia. Conclusões A curto prazo essa técnica é segura e eficaz na recuperação da pseudoparesia e na melhora da dor, da função e da força do ombro.

Correlation of Physical Examination with Arthroscopic Findings in the Treatment of Rotator Cuff Tear / Correlação do exame físico com achados artroscópicos no tratamento da ruptura do manguito rotador

Abstract Objective To compare clinical data from the physical examination with arthroscopic findings in rotator cuff rupture. Methods A total of 177 patients submitted to arthroscopic treatment of rotator cuff rupture were selected, and arthroscopic findings were compared with physical examination. Results The impingement tests showed high sensitivity for rotator cuff rupture. Among the strength tests, the most sensitive was the Patte test (85.7%), and the one with the highest positive predictive value (PPV) was the Jobe test (95%). The Drop Sign test showed higher specificity and negative predictive value (NPV) (98.7 and 95.9%, respectively). Patients with a history of trauma were 3.5 times more likely to have a positive Lift Off test. Conclusion The impingement tests had high sensitivity for rotator cuff ruptures. The Jobe test showed similar sensitivity among patients who had partial or total supraspinal injury. For complete lesions of the subscapularis, The Lift Off and Belly Press tests showed high sensitivity and specificity.

Resumo Objetivo Comparar dados clínicos do exame físico com os achados artroscópicos na ruptura do manguito rotador. Métodos Foram selecionados 177 pacientes submetidos ao tratamento artroscópico de ruptura do manguito rotador e foram comparados os achados artroscópicos com o exame físico. Resultados Os testes irritativos de impacto apresentaram alta sensibilidade para ruptura do manguito rotador. Dentre os testes de força, o de maior sensibilidade foi o teste de Patte (85,7%) e o de maior valor preditivo positivo (VPP) foi o teste de Jobe (95%). O teste Drop Sign apresentou maior especificidade e valor preditivo negativo (VPN) (98,7 e 95,9%, respectivamente). Pacientes com história de trauma possuíam 3,5 vezes mais chances de apresentarem o teste Lift Off positivo. Conclusão Os testes irritativos tiveram alta sensibilidade para rupturas do manguito rotador. O teste de Jobe apresentou sensibilidade semelhante entre os pacientes que tinham lesão parcial ou total do supraespinhal. Para as lesões completas do subescapular, as testes Lift Off e Belly Press apresentaram alta sensibilidade e especificidade.

Is the isometric strength of the shoulder associated with functional performance tests in overhead athletes?

OBJECTIVE: To verify the association of the isometric strength of the shoulder external rotators (ER) and serratus anterior (SA) with the performance of functional tests CKCUEST, SMB-T, and USSP-T in overhead athletes. DESIGN: Cross-sectional study. PARTICIPANTS: Eighty overhead athletes with no history of surgery in the upper and lower limbs and trunk in the past year, and no painful symptoms in the upper body during the physical assessment were included. MAIN OUTCOME MEASURES: Preseason assessment included isometric strength of shoulder ER and SA, and performance of the CKCUEST, SMB-T, and USSP-T. Multiple linear regression analysis was performed to identify if the isometric strength of the shoulder ER and SA could explain the performance during the tests after controlling for sex. RESULTS: The isometric strength of SA was associated (p < 0.05) with the SMB-T and USSP-T with 4% of explain. The isometric strength of the SA was not associated (p > 0.05) with the CKCUEST. The isometric strength of the ER was not associated (p > 0.05) with any of the tests. CONCLUSION: The isometric strength of the SA predicted the SMB-T and USSP-T performance. Isometric strength of SA and shoulder ER was not associated with CKCUEST results in athletes overhead.

Superior labral anterior and posterior (SLAP) lesions of the long bicep insertion on the glenoid: management in athletes.

INTRODUCTION: SLAP injuries are common in athletes but there is no consensus on different aspects such as pathophysiology and treatment options. Currently, the main controversy in the treatment of SLAP II injuries is deciding whether to make a repair or tenodesis. Clinical outcomes have varied according to the patients' age, sports, or work activity. This review aims to present the evidence at points of contention regarding pathophysiology, treatment options, outcomes, return to activities, and complications of type II SLAP. MATERIAL AND METHODS: The relevant literature on SLAP injuries and their treatment options and results were identified from PubMed and a narrative review was performed. RESULTS: Repairing SLAP II injuries seems to show better outcomes in younger patients and athletes who perform overhead movements, while tenodesis (in its various technical options) yields better outcomes in older patients, both as a single injury or associated with other pathologies such as rotator cuff injury or tenosynovitis. On the other hand, there currently seems to be a trend of increasing the indication of tenodesis even in underage patients and athletes, given that there are reports of fewer re-operations and a faster recovery. CONCLUSION: The evidence is unclear as to which factors influence the failure to achieve optimal outcomes even in cases with anatomical repairs. Studies with a high level of evidence including different variables are necessary to define when to repair, perform tenodesis, and what surgical technique to use for both options.
