RESUMEN
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.

Objective: Evaluating intra- and inter-observer agreement of the Neer, AO, and AO/OTA proximal humerus fractures classification systems in adults. Methods: In total, 100 X-rays of patients with proximal humerus fractures were selected according to the inclusion and exclusion criteria established in this study. They were evaluated by four evaluators with different levels of expertise. The evaluation was performed at two distinct moments, with an interval of 21 days between each analysis. Images were randomized for the second evaluation by a researcher who did not participate in the image selection process. A Fleiss Kappa test was performed to evaluate intra- and inter-observer agreement. Results: We observed a substantial agreement with k = 0.669, k = 0.715, and k = 0.780 for the Neer, AO, and AO/OTA classification systems, respectively. Conclusion: In the second evaluation, intra-observer agreement improved. In the first evaluation, we obtained values of k = 0.724, k = 0.490, and k = 0.599 for the evaluation of the Neer, AO, and AO/OTA classifications. In the second evaluation, the values k = 0.759, k = 0.772, and k = 0.858. Therefore, the evaluations went from moderate to substantial for the AO classification and from moderate to practically perfect for the AO/OTA classification. The level of inter-observer agreement was substantial (0.61-0.80), with k = 0.669, k = 0.715, and k = 0.780 for the Neer, AO, and AO/OTA classifications, respectively. Level of Evidence III, Cross-Sectional Observational Study.

RESUMEN
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.

BACKGROUND: Proximal humerus fractures (PHF) are frequent, however, several studies show low inter-rater agreement in the diagnosis and treatment of these injuries. Differences are usually related to the experience of the evaluators and/or the diagnostic methods used. This study was designed to investigate the hypothesis that shoulder surgeons and diagnostic imaging specialists using 3D printing models and shoulder CT scans in assessing proximal humerus fractures. METHODS: We obtained 75 tomographic exams of PHF to print three-dimensional models. After, two shoulder surgeons and two specialists in musculoskeletal imaging diagnostics analyzed CT scans and 3D models according to the Neer and AO/OTA group classification and suggested a treatment recommendation for each fracture based on the two diagnostic methods. RESULTS: The classification agreement for PHF using 3D printing models among the 4 specialists was moderate (global k = 0.470 and 0.544, respectively for AO/OTA and Neer classification) and higher than the CT classification agreement (global k = 0.436 and 0.464, respectively for AO/OTA and Neer). The inter-rater agreement between the two shoulder surgeons were substantial. For the AO/OTA classification, the inter-rater agreement using 3D printing models was higher (k = 0.700) than observed for CT (k = 0.631). For Neer classification, inter-rater agreement with 3D models was similarly higher (k = 0.784) than CT images (k = 0.620). On the other hand, the inter-rater agreement between the two specialists in diagnostic imaging was moderate. In the AO/OTA classification, the agreement using CT was higher (k = 0.532) than using 3D printing models (k = 0.443), while for Neer classification, the agreement was similar for both 3D models (k = 0.478) and CT images (k = 0.421). Finally, the inter-rater agreement in the treatment of PHF by the 2 surgeons was higher for both classifications using 3D printing models (AO/OTA-k = 0.818 for 3D models and k = 0.537 for CT images). For Neer classification, we saw k = 0.727 for 3D printing models and k = 0.651 for CT images. CONCLUSION: The insights from this diagnostic pilot study imply that for shoulder surgeons, 3D printing models improved the diagnostic agreement, especially the treatment indication for PHF compared to CT for both AO/OTA and Neer classifications On the other hand, for specialists in diagnostic imaging, the use of 3D printing models was similar to CT scans for diagnostic agreement using both classifications.

RESUMEN
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.

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.

OBJECTIVE: To evaluate the choice of surgical approach among Brazilian orthopedists and whether shoulder surgery specialty training or duration of experience influences the decision-making. METHODS: A questionnaire on the preferred approach and complications was administered to orthopedic surgeons with and without shoulder specialization training. The chi-square test or Fisher's exact test was applied. RESULTS: We interviewed 114 orthopedists, 49 (43.0%) traumatologists, 36 (31.5%) specialist surgeons, and 29 (25%) shoulder surgery specialist residents. In cases of fracture without dislocation, specialized training and duration of experience did not influence the approach used (primarily deltopectoral). In cases of fracture/dislocation, 97.2% of the specialists versus 82.1% of the traumatologists opted for the deltopectoral approach (p = 0.034). In cases of fractures/dislocation, 92.5% of surgeons with more than 5 years of experience and 78.7% with less than 5 years of experience opted for the deltopectoral approach (p = 0.032). CONCLUSION: Specialization in shoulder surgery did not influence surgeons' approaches to manage fractures without dislocation. In cases of fracture/dislocation, shoulder surgery specialization training and duration of experience were associated with selection of the deltopectoral approach.

OBJETIVO: Avaliar a via de acesso de escolha entre os ortopedistas brasileiros e se a formação de especialista em cirurgia do ombro e/ou tempo de experiência influenciam nessa decisão. MÉTODOS: Realizou-se questionário entre ortopedistas, com e sem especialização em ombro, sobre qual a via de acesso preferida e as complicações observadas. Aplicou-se o teste do qui-quadrado ou o teste exato de Fisher. RESULTADOS: Foram entrevistados 114 ortopedistas, 49 (43,0 %) traumatologistas, 36 (31,5 %) cirurgiões especialistas e 29 (25 %) residentes de especialização em cirurgia do ombro. Nas fraturas sem luxação a formação especializada e o tempo de experiência não influenciaram na escolha (maioria deltopeitoral). Na fratura/luxação, 97,2% dos especialistas optaram pela deltopeitoral, comparado com 82,1% dos traumatologistas (p=0,034). Nas fraturas/luxação, cirurgiões com experiência superior a 5 anos optaram pela deltopeitoral (92,5%) e aqueles com menos de 5 anos optaram pela via deltopeitoral (78,7%) (p=0,032). A diminuição do arco de movimento (ADM) foi a complicação mais relatada. CONCLUSÃO: A especialização em cirurgia do ombro não influenciou na escolha nas fraturas sem luxação. Na fratura/luxação, a especialização e o tempo de experiência associaram-se à escolha da via deltopeitoral. A complicação mais frequente foi a diminuição do ADM, principalmente entre os cirurgiões do Ombro. Nível de Evidência V, Opinião de especialistas.

RESUMEN
ABSTRACT Objective: To evaluate the correlation between the UCLA and Constant-Murley scores in the surgical treatment of rotator cuff tears and proximal humeral fractures (PHF). Methods: Retrospective study evaluating patients submitted to arthroscopic rotator cuff repair and surgical treatment of PHF with 2-year follow-up. Patients were evaluated by the UCLA and Constant-Murley scores in the preoperative period for the rotator cuff repairs, and 3, 6, 12 and 24 months after surgery for both diagnoses. Pearson's correlation coefficient (r) was calculated to measure the degree of correlation between the two clinical scales. Results: We evaluated 109 patients: 54 with rotator cuff tear and 55 with PHF. Twenty-four months after surgical treatment, the scores according to the UCLA and Constant-Murley scores were 32.6 ± 4.0 and 85.0 ± 12.0 for the rotator cuff tears and 30.3 ± 5.3 and 73.8 ± 13.9 for the PHF, demonstrating significant improvements in both, in relation to the initial evaluation (p < 0.001). The scales demonstrated high correlation (r = 0.88, p < 0.001). The scores obtained in the two scales showed high or very high correlation in all the postoperative clinical evaluations (r = 0.79-0.91, p < 0.001). The correlation was high in the preoperative evaluation (r = 0.73, p < 0.001). Conclusion: The UCLA and Constant-Murley scores presented high or very high correlation in the evaluation of surgical treatment of rotator cuff tears and PHF. The correlation in the preoperative evaluation was high.
RESUMO Objetivo: Avaliar a correlação entre as escalas da UCLA e de Constant-Murley no tratamento cirúrgico de roturas do manguito rotador e de fraturas da extremidade proximal do úmero (FEPU). Métodos: Estudo retrospectivo, que avaliou pacientes submetidos ao reparo do manguito rotador por via artroscópica e tratamento cirúrgico de FEPU com dois anos de seguimento. Os pacientes foram avaliados pelas escalas da UCLA e de Constant-Murley no período pré-operatório nas roturas do manguito rotador e após seis, 12 e 24 meses da cirurgia em ambos os diagnósticos. O coeficiente de correlação de Pearson (r) foi calculado para medir o grau de correlação entre as duas escalas clínicas. Resultados: Avaliamos 109 pacientes, 54 com rotura do manguito rotador e 55 com FEPU. Após 24 meses do tratamento cirúrgico, as pontuações pelas escalas da UCLA e da Constant-Murley foram de 32,6 ± 4,0 e 85,0 ± 12,0 nas roturas do manguito rotador e 30,3 ± 5,3 e 73,8 ± 13,9 nas FEPU, com melhoria significativa em ambas em relação à avaliação inicial (p < 0,001). As escalas demostraram alta correlação (r = 0,88, p < 0,001). Em todas as avaliações clínicas pós-operatórias as pontuações obtidas nas duas escalas se correlacionaram de modo alto ou muito alto (r = 0,79 a 0,91, p < 0,001). No pré-operatório a correlação foi alta (r = 0,73, p < 0,001). Conclusão: As escalas da UCLA e de Constant-Murley apresentam uma correlação alta ou muito alta na avaliação do tratamento cirúrgico das roturas do manguito rotador e das FEPU. No pré-operatório a correlação é alta.

Patients were evaluated by the UCLA and Constant-Murley scores in the preoperative period for the rotator cuff repairs, and 3, 6, 12 and 24 months after surgery for both diagnoses. Pearson's correlation coefficient (r) was calculated to measure the degree of correlation between the two clinical scales. RESULTS: We evaluated 109 patients: 54 with rotator cuff tear and 55 with PHF. Twenty-four months after surgical treatment, the scores according to the UCLA and Constant-Murley scores were 32.6 ± 4.0 and 85.0 ± 12.0 for the rotator cuff tears and 30.3 ± 5.3 and 73.8 ± 13.9 for the PHF, demonstrating significant improvements in both, in relation to the initial evaluation (p < 0.001). The scales demonstrated high correlation (r = 0.88, p < 0.001). The scores obtained in the two scales showed high or very high correlation in all the postoperative clinical evaluations (r = 0.79-0.91, p < 0.001). The correlation was high in the preoperative evaluation (r = 0.73, p < 0.001). CONCLUSION: The UCLA and Constant-Murley scores presented high or very high correlation in the evaluation of surgical treatment of rotator cuff tears and PHF. The correlation in the preoperative evaluation was high.
OBJETIVO: Avaliar a correlação entre as escalas da UCLA e de Constant-Murley no tratamento cirúrgico de roturas do manguito rotador e de fraturas da extremidade proximal do úmero (FEPU). MÉTODOS: Estudo retrospectivo, que avaliou pacientes submetidos ao reparo do manguito rotador por via artroscópica e tratamento cirúrgico de FEPU com dois anos de seguimento. Os pacientes foram avaliados pelas escalas da UCLA e de Constant-Murley no período pré-operatório nas roturas do manguito rotador e após seis, 12 e 24 meses da cirurgia em ambos os diagnósticos. O coeficiente de correlação de Pearson (r) foi calculado para medir o grau de correlação entre as duas escalas clínicas. RESULTADOS: Avaliamos 109 pacientes, 54 com rotura do manguito rotador e 55 com FEPU. Após 24 meses do tratamento cirúrgico, as pontuações pelas escalas da UCLA e da Constant-Murley foram de 32,6 ± 4,0 e 85,0 ± 12,0 nas roturas do manguito rotador e 30,3 ± 5,3 e 73,8 ± 13,9 nas FEPU, com melhoria significativa em ambas em relação à avaliação inicial (p < 0,001). As escalas demostraram alta correlação (r = 0,88, p < 0,001). Em todas as avaliações clínicas pós-operatórias as pontuações obtidas nas duas escalas se correlacionaram de modo alto ou muito alto (r = 0,79 a 0,91, p < 0,001). No pré-operatório a correlação foi alta (r = 0,73, p < 0,001). CONCLUSÃO: As escalas da UCLA e de Constant-Murley apresentam uma correlação alta ou muito alta na avaliação do tratamento cirúrgico das roturas do manguito rotador e das FEPU. No pré-operatório a correlação é alta.
RESUMEN
OBJECTIVE: To evaluate supraspinatus tendon integrity with ultrasound (US) in patients submitted to proximal humeral fracture (PHF) fixation with a locking intramedullary nail. METHODS: Thirty-one patients with PHF treated with curvilinear locking intramedullary nail, aged between 50 and 85 years, were assessed by US at six months postoperatively and clinically at six and 12 months postoperatively. The primary aim was supraspinatus tendon integrity, evaluated by US at six months postoperatively. Secondary aims included the Constant-Murley, DASH score, and visual analog pain scores, as well as complications and reoperation rates. RESULTS: Full-thickness rotator cuff ruptures were observed in four patients (13%), supraspinatus ruptures in three cases (10%), and subscapularis ruptures in one case (3%). Partial ruptures were diagnosed in 10 cases (32%). The results using the Constant-Murley score at 12 months were 71.3 ± 15.2 points for the entire series, with 73.2 ± 16.1 points for patients without rotator cuff ruptures and 68.7 ± 14.1 points for those with partial or complete ruptures, without a statistically significant difference (p = 0.336). Complications, exclusively for rotator cuff ruptures, were observed in nine patients (29%). CONCLUSION: A high rate of rotator cuff ruptures was demonstrated, with partial ruptures in 32% of cases and full-thickness ruptures in 13%. However, clinical results are satisfactory, and are not influenced by the presence of rotator cuff ruptures.
OBJETIVO: Avaliar a integridade do tendão do supraespinal por meio da ultrassonografia (US) em pacientes submetidos à fixação de fraturas da extremidade proximal do úmero (FEPU) com haste intramedular bloqueada. MÉTODOS: Foram avaliados por exame de ultrassonografia aos seis meses de pós-operatório e clinicamente aos seis e 12 meses de pós-operatório 31 pacientes com FEPU entre 50 e 85 anos, tratados com haste intramedular bloqueada inclinada. O objetivo primário foi avaliar a integridade do tendão supraespinal e os secundários incluíam descrever os demais achados da ultrassonografia, as escalas de Constant-Murley, EVA e Dash e a taxa de complicações e comparar os resultados clínicos dos pacientes com e sem rotura do manguito rotador. RESULTADOS: Roturas transfixantes do manguito rotador foram observadas em quatro pacientes (13%), com rotura do supraespinal em três casos (10%) e do subescapular em um caso (3%). Roturas parciais foram diagnosticadas em dez casos (32%). Os resultados pela escala de Constant-Murley aos 12 meses foram de 71,3 ± 15,2 pontos para toda a amostra, de 73,2 ± 16,1 pontos para os pacientes sem rotura do manguito rotador e de 68,7 ± 14,1 pontos para aqueles com rotura parcial ou completa (p = 0,336). Complicações, exclusive a rotura do manguito rotador, foram observadas em nove pacientes (29%). CONCLUSÃO: Observou-se uma alta taxa de alterações nos tendões do manguito rotador, com roturas parciais em 32% dos casos e transfixantes em 13%. No entanto, os resultados clínicos são satisfatórios, não influenciados pela presença de rotura do manguito rotador.
RESUMEN
INTRODUCTION: Proximal humerus fractures (PHF) are common fractures and are the third most common type of fractures among older adults. The most commonly used implants include the locking plate and the locking intramedullary nail. Areas covered: The aim of this study is to perform a literature review of biomechanical and clinical studies that compare the locking plate and intramedullary nail for PHF osteosynthesis. Expert commentary: Twelve clinical studies and seven biomechanical studies were identified that met this criterion. The findings of this review showed that intramedullary nailing and locking plate fixation yielded similar functional results, but with contrasting complication rates. The biomechanical studies showed controversial results, with most of the studies demonstrating better biomechanical properties for the intramedullary nail. Different types of intramedullary nail for PHF have different characteristics, with curvilinear nails presenting a higher risk of complications.

Shoulder fracture-dislocations are uncommon. Those associated with intrathoracic dislocation are very rare conditions, resulting from high-energy trauma; usually, the affected limb is in an abduction position. In Brazil, there is only one report of a teenager with displacement of the epiphysis into the chest cavity; the present is the first adult patient report of intrathoracic dislocation of the humerus. The authors present the case of a patient female, aged 56 years, who was hit by motorcycle and thrown approximately 5 meters away. She was rescued on site with thoracic, pelvic, and right upper limb trauma. Her chest was drained due to pneumothorax and multiple fractures of ribs; she was diagnosed with fracture-dislocation in four parts, with intrathoracic dislocation of the humeral head. Displaced forearm bones fracture was also diagnosed; the olecranon, scaphoid, and ischiopubic fractures were not displaced. The patient underwent a joint procedure with a cardiothoracic surgery team to remove the humeral head through thoracotomy and chest drainage; subsequently, a partial arthroplasty of the humerus was performed, with graft from the humeral head and fixation of forearm fractures. Conservative treatment was chosen for the other fractures. After three months, all fractures were healed with gradual functional improvement. The patient remained in physiotherapy and orthopedic monitoring, having been discharged from the thoracic surgery; in a severe depressive episode, the patient committed suicide after 11 months of the trauma.

OBJECTIVE: This study aimed to assess the outcomes of patients with humeral head fractures treated by reduction and osteosynthesis. METHOD: A total of 53 shoulders (52 patients) with humeral head fractures were operated between October 1996 and December 2009. Patients previously treated with primary arthroplasty and/or those who had less than two years follow-up were excluded. A total of 34 shoulders of 34 patients were therefore reassessed. In the sample studied, 23 patients were male and mean age was 47 years. Cases were assessed based on the UCLA score. RESULTS: Mean post-operative follow-up was 50 months. Twelve patients evolved with excellent outcome, seven good, five regular, and ten with poor outcome (55.8% satisfactory and 44.2% unsatisfactory outcomes). Mean UCLA score was 26 points. Mean post-operative range of motion measurements was 117° elevation, 36° LR and L1 MR. At the immediate post-operative radiography, anatomic reduction was evident in 17 patients (50%). Necrosis was detected in 18 patients, six Grade II and 12 Grade III cases. Female gender and anatomically reduced fractures were statistically better at UCLA scale (p = 0.01 and p = 0.0001 respectively). CONCLUSIONS: Female patients had a higher mean UCLA score than male patients (p = 0.01). Anatomically reduced fractures had higher UCLA scores (p = 0.0001) and lower necrosis rate (p = 0.0001). Reconstruction of humeral head fractures had a satisfactory outcome in 55.8% of cases and should be indicated in young and active patients.
OBJETIVO: Avaliar os resultados dos pacientes com fraturas epifisárias tratados com redução e osteossíntese. MÉTODO: Entre outubro de 1996 e dezembro de 2009 foram operados 53 ombros (52 pacientes) com fraturas epifisárias. Foram excluídos os pacientes tratados com artroplastia primária e/ou que tinham seguimento inferior a dois anos. Foram reavaliados 34 ombros de 34 pacientes, 23 do sexo masculino, com média de 47 anos. A avaliação foi feita com a escala da UCLA. RESULTADOS: O tempo de seguimento pós-operatório médio foi de 50 meses. Doze pacientes evoluíram com resultados excelentes, sete bons, cinco regulares e dez maus (55,8% de resultados satisfatórios e 44,2% de insatisfatórios). O escore UCLA teve média de 26 pontos. As médias de mobilidade pós-operatória foram de 117° de elevação, 36° de RL e L1 de RM. No RX pós-operatório imediato, verificamos a redução anatômica em 17 pacientes (50%). A necrose foi constatada em 18 pacientes, seis grau II e 12 grau III. Sexo feminino e fraturas reduzidas anatomicamente foram estatisticamente melhores na escala da UCLA (p = 0,01 e p = 0,0001 respectivamente). CONCLUSÕES: O sexo feminino teve um valor médio do UCLA superior ao sexo masculino (p = 0,01). As fraturas reduzidas anatomicamente obtiveram UCLA superior (p = 0,0001) e um menor índice de necrose (p = 0,0001). A reconstrução das fraturas epifisárias levou a resultados satisfatórios em 55,8%, deve ser indicada para pacientes jovens e ativos.

OBJECTIVE: To correlate the functional outcomes and radiographic indices of proximal humerus fractures treated using an anatomical locking plate for the proximal humerus. METHODS: Thirty-nine patients with fractures of the proximal humerus who had been treated using an anatomical locking plate were assessed after a mean follow-up of 27 months. These patients were assessed using the University of California Los Angeles (UCLA) score and their range of motion was evaluated using the method of the American Academy of Orthopedic Surgeons on the operated shoulder and comparative radiographs on both shoulders. The correlation between radiographic measurements and functional outcomes was established. RESULTS: We found that 64% of the results were good or excellent, according to the UCLA score, with the following means: elevation of 124°; lateral rotation of 44°; and medial rotation of thumb to T9. The type of fracture according to Neer's classification and the patient's age had significant correlations with the range of motion, such that the greater the number of parts in the fracture and the greater the patient's age were, the worse the results also were. Elevation and UCLA score were found to present associations with the anatomical neck-shaft angle in anteroposterior view; fractures fixed with varus deviations greater than 15° showed the worst results (p < 0.001). CONCLUSION: The variation in the neck-shaft angle measurements in anteroposterior view showed a significant correlation with the range of motion; varus deviations greater than 15° were not well tolerated. This parameter may be one of the predictors of functional results from proximal humerus fractures treated using a locking plate.
OBJETIVO: Correlacionar os resultados funcionais e os índices radiográficos das fraturas do úmero proximal tratadas com placa anatômica bloqueada para úmero proximal. MÉTODOS: Examinaram-se 39 pacientes com fraturas do úmero proximal tratados com placa anatômica bloqueada, com seguimento médio de 27 meses. Esses pacientes foram submetidos à análise do escore da Universidade da Califórnia de Los Angeles (UCLA) e à avaliação do arco de movimento pelo método da Academia Americana de Cirurgiões Ortopédicos no ombro operado e a exames radiográficos comparativos de ambos os ombros. Estabeleceu-se a correlação entre as medidas radiográficas e os resultados funcionais. RESULTADOS: Obtivemos 64% de bons e excelentes resultados conforme o escore da UCLA, com médias de 124° de elevação; 44° de rotação lateral; e polegar-T9 de rotação medial. O tipo de fratura, de acordo com a classificação de Neer, e a idade do paciente tiveram significativa correlação com o arco de movimentos; quanto maiores o número de partes das fraturas e a idade dos pacientes, piores os resultados. Encontrou-se associação entre a elevação e o escore da UCLA com o ângulo cervicodiafisário na incidência anteroposterior; as fraturas fixadas com desvios em varo maiores do que 15° apresentaram os piores resultados (p < 0,001). CONCLUSÃO: A variação da medida do ângulo cervicodiafisário na incidência anteroposterior mostrou significativa correlação com o arco de movimento; desvios em varo maiores do que 15° não foram bem tolerados. Esse parâmetro pode ser um dos preditores dos resultados funcionais nas fraturas do úmero proximal tratadas com placa anatômica bloqueada.
