RESULTS FROM LATARJET SURGERY FOR TREATING TRAUMATIC ANTERIOR SHOULDER INSTABILITY ASSOCIATED WITH BONE EROSION IN THE GLENOID CAVITY, AFTER MINIMUM FOLLOW-UP OF ONE YEAR

ABSTRACTObjective: Evaluate the results from the Latarjet procedure in patients with anterior recurrent dislocation of the shoulder who present bone loss of the glenoid cavity greater than 25%. Methods: Twenty six male patients underwent the Latarjet procedure, The bone loss was evaluated by means of radiography using the Bernageau view and by means of CAT scan. The patients were evaluated with regard to range of motion, using the Rowe and UCLA scales, before and after the operation, and by radiographs to assess the presence of arthrosis, position and consolidation of the graft and positioning of the screws. Statistical analysis was used to assess whether there was any relationship between the number of episodes of dislocation and the presence of arthrosis, , and any relationship between arthrosis and limitations on lateral rotation. Differences in range of motion between the operated and unaffected sides and in the UCLA and Rowe scale. Results: The means for elevation and lateral rotation were statistically poorer on the operated side. The UCLA and Rowe scale showed that there was a statistically significant improvement in the clinical-functional results (P < 0.001 for both). There was a relationship between the number of episodes of dislocation and the presence of arthrosis, We also did not observe any correlation between limitations on lateral rotation and arthrosis. Conclusion: The Latarjet procedure is an efficient method for cases of severe erosion of the glenoid margin

Cut Out Complications and Anisomelia of the Lower Limbs In Surgery With Valgus Reduction for Intertrochanteric Fractures

Background: The proximal fractures of the femur are counted among the group of orthopedic and traumatic pathologies which consume most of the financial resources set aside for health worldwide. Surgical treatment continues to be the treatment of choice for intertrochanteric fractures of the femur. However, although the surgical treatment of the proximal fracture of the femur is widely known and accepted in the orthopedic field, it is not without risk with the cut out being the most feared complication. Objective: This paper describes the complications of cut out or the anisomelia of the lower limbs of patients with intertrochanteric fractures who underwent valgus reduction surgery. Method: Sixty-one patients with 3rd and 4th degree, according to Tronzo classification, intertrochanteric fractures underwent surgery with the use of Dynamic hip screw type sliding screw and valgus reduction. The data were analyzed one year after surgery, when a functional assessment was made by scanometry, Tip-Apex Distance index diaphyseal cervical angle and the modified Merle d'Aubigné &amp; Postel questionnaire. Kruskal-Wallis and Mann-Whitney tests were used for the statistical analysis, Spearman’s correlation test for the quantitative variables and the chi-squared test for the qualitative variables. Results: The correlation between the Tip-Apex Distance index and the diaphyseal cervical angle was statistically significant (rho=0.391, p=0.002), while the correlations between the Tip-Apex Distance index and the scanometry and the diaphyseal cervical angle and the scanometry were not significantly correlated. In accordance with the modified Merle d’Aubigné &amp; Postel questionnaire, 23 patients (37.7%) achieved a very good result, 29 patients (47.5%) had a good result, five patients (8.2%) obtained a moderately good result, one patient (1.6%) presented a reasonable result and three patients (4.9%) obtained a poor result. Conclusion: No cut out complications occurred in the 3rd and 4th degree intertrochanteric fractures with a Baumgaertner index ≥ 25 mm, when the reduction and valgus fixation of the intertrochanteric fracture was performed with the Dynamic hip screw type sliding pin, as there was also, in the majority of patients, no anisomelia of the lower limbs

A new method to evaluate glenoid erosion in instable shoulder

Background: We aimed to establish values and parameters using multislice reconstruction in axial computerized tomography (CT) in order to quantify the erosion of the glenoid cavity in cases of shoulder instability. Methods: We studied two groups using CT. Group I had normal subjects and Group II had patients with shoulder instability. We measured values of the vertical segment, the superior horizontal, medial and inferior segments, and also calculated the ratio of the horizontal superior and inferior segments of the glenoid cavity in both normal subjects and those with shoulder instability. These variables were recorded during arthroscopy for cases with shoulder instability.\ud \ud \ud \ud Results\ud The mean values were 40.87 mm, 17.86 mm, 26.50 mm, 22.86 mm and 0.79 for vertical segment, the superior horizontal, medial and inferior segments, and the ratio between horizontal superior and inferior segments of the glenoid cavity respectively, in normal subjects. For subjects with unstable shoulders the mean values were 37.33 mm, 20.83 mm, 23.07 mm and 0.91 respectively. Arthroscopic measurements yielded an inferior segment value of 24.48 mm with a loss of 2.39 mm (17.57%). The ratio between the superior and inferior segments of the glenoid cavity was 0.79. This value can be used as a normative value for evaluating degree of erosion of the anterior border of the glenoid cavity. However, values found using CT should not be used on a comparative basis with values found during arthroscopy. Conclusions: Computerized tomographic measurements of the glenoid cavity yielded reliable values consistent with those in the literature.The funding body provided financial support to make all procedures and in the decision to submit the manuscript for publication

Estudo da resistência do tendão do supra-espinal com pontos simples, duplos e Mason Allen

OBJETIVO: O objetivo do trabalho foi comparar a resistência entre os pontos simples, duplo e Mason-Allen modificado, utilizados para o reparo do manguito rotador, e verificar se há diferença significativa que justifique a utilização do ponto do tipo Mason-Allen modificado ao invés dos pontos simples ou duplo. MÉTODO: Retiramos tendões do músculo supra-espinal de 15 cadáveres humanos frescos (30 ombros), com a média de idade de 45 anos. Os testes foram realizados na máquina universal de ensaio mecânico Kratos® 500/2000 e os resultados submetidos aos testes estatísticos de t-student, análise de variância (ANOVA), comparação múltipla de Bonferroni e calculadas as correlações de Pearson. Os testes foram realizados ao nível de significância de 5%. RESULTADOS: Não houve diferença significativa com relação à idade, ao tamanho das amostras e deslocamento do tendão. A resistência variou com média de 127,50 N com o ponto simples, 163,95 N com o duplo e com o ponto de Mason-Allen modificado esta foi de 198,45 N. CONCLUSÃO: não existe diferença da resistência no tendão quanto à falha na interface sutura - tendão comparando-se o ponto duplo com o Mason-Allen modificado e os pontos simples e duplo, porém há diferença quando comparados os pontos simples e Mason-Allen modificado

Luxação recidivante do ombro: aspectos do período entre o primeiro episódio e o tratamento cirúrgico Recurrent shoulder dislocation: aspects between the first episode and surgical treatment

OBJETIVO: Determinar: 1) se os pacientes que sofrem seu primeiro episódio de luxação traumática do ombro são orientados a manter imobilização por um período mínimo de quatro semanas e qual foi o tipo de imobilização prescrita; 2) determinar após quantos episódios de luxação os pacientes receberam a informação da necessidade de cirurgia; 3) quanto tempo os pacientes demoraram a conseguir acompanhamento com especialista em cirurgia de ombro; 4) quantos episódios de luxação os pacientes apresentavam no momento da cirurgia. MÉTODOS: Dos 100 pacientes tratados cirurgicamente ou estão aguardando cirurgia nos ambulatórios, foram avaliados 61, que responderam a um questionário com perguntas relacionadas com o mecanismo das luxações, locais de atendimento, orientações recebidas para o tratamento do evento agudo e acompanhamento, tempo necessário para conseguir o acompanhamento e cirurgia.Os dados coletados foram submetidos à análise. RESULTADOS: Apenas 13 pacientes (22%) receberam orientações adequadas sobre sua afecção, prognóstico quanto à recidiva e à necessidade de acompanhamento especializado e cirurgia nos casos recidivantes. Nenhum paciente foi orientado adequadamente como e por quanto tempo deveria ficar imobilizado. CONCLUSÃO: Nenhum paciente recebeu orientações de manter-se imobilizado por quatro semanas e o tipo de imobilização variou entre uma tipoia simples e a imobilização comercial tipo Velpeau. A maioria dos pacientes avaliados (78%) não recebeu orientações corretas sobre a necessidade de acompanhamento especializado e cirurgia após o segundo episódio de luxação. O tempo para avaliação do especialista demorou entre quatro e seis meses e possuíam entre um e cem episódios de luxação no momento da cirurgia.<br>OBJECTIVE: To determine: 1) whether the patients had been oriented to use immobilization for at least four weeks and which type of immobilization was prescribed, 2) how many dislocations occurred until the patient received information about the need of surgery, 3) How long it takes for patients to have an appointment with a shoulder surgeon, 4) How many dislocations the patient had at the time of surgery. Material and METHODS: Of the 100 patients surgically treated or waiting for surgery at outpatient facilities, we interviewed 61 patients with questions related to the mechanism of dislocation, emergency service sites, guidelines for acute event treatment and follow-up, time elapsed until surgery and follow-up. Collected data were submitted to analysis. RESULTS: Only 13 patients (22%) had received correct information about their lesion, prognosis concerning recurrence, and about the need of surgery and expert follow-up in recurrent cases. None of our patients received proper information about type and duration of immobilization. CONCLUSION: None of our patients had received proper orientation to remain immobilized for four weeks, and the types of immobilization vary from a handmade sling to a manufactured Velpeau. Most of our patients (78%) did not receive proper orientation about specialized follow-up and surgery after their second episode of dislocation. The time for a specialized appointment with shoulder surgeon ranges from four to six months, with 1-100 dislocation episodes at the moment of surgery

Mensuração da erosão da borda anterior da glenoide através do exame radiográfico: uma forma simples de realizar a incidência de Bernageau Anterior glenoid rim erosion measured by X-Ray exam: a simple way to perform the Bernageau profile view

OBJETIVO: Analisar se a incidência radiográfica de Bernageau é adequada para estudar a borda anterior da glenoide e determinar a distância entre a borda anterior e posterior da glenoide. MÉTODO: Cinquenta pacientes (31 do sexo masculino) com idade média de 34 anos, foram avaliados posicionando-se o braço em flexão anterior de 160º e o corpo a 70º do chassi radiográfico, enquanto o posicionamento da ampola de raios-X era de 30º crânio-caudal, centrada na espinha da escápula. Dos autores, três mensuraram três vezes a distância entre a borda anterior e posterior da glenoide. Foram estudadas a variabilidade e a reprodutibilidade dessa distância. Três cirurgiões de ombro realizaram uma avaliação subjetiva, respondendo se era possível a avaliação da borda anterior da glenoide na incidência estudada. RESULTADOS: A distância foi em média 24,48mm ± 0,332mm (esquerdo) e 24,82mm ± 0,316mm (direito). O teste de Anderson-Darling mostrou que as medidas tiveram distribuição normal e a correlação de Pearson's mostrou reprodutibilidade significativa (P < 0,01). O primeiro observador concluiu que 67% das radiografias eram adequadas para avaliar a borda anterior da glenoide, o segundo concluiu que 81% e o terceiro 78% eram satisfatórias para a avaliação. O coeficiente Kappa mostrou que o segundo e terceiro examinadores apresentaram concordância substancial em suas opiniões. CONCLUSÃO: A incidência de Bernageau proporciona uma radiografia adequada para o estudo da borda anterior da glenoide e para o cálculo da sua erosão após a comparação com o lado não acometido.<br>OBJECTIVE: To analyze whether the Bernageau view is adequate for studying the anterior glenoid rim and determining the distance between the posterior and anterior glenoid rim. METHODS: Fifty patients (31 males) with a mean age of 34 years were evaluated by positioning their arm at 160º forward flexion and body at 70º with the X-Ray chassis, while positioning the X-ray tube at 30º craniocaudal, centered on the scapula spine. Three of the authors measured the distance between the posterior and anterior glenoid rim three times. The variability and reproducibility of this distance were studied. Three shoulder surgeons performed a subjective evaluation by answering whether it was possible to evaluate the anterior glenoid rim in the view studied. RESULTS: The average distance was 24.48 mm ±0.332 mm (left) and 24.82 mm ±0.316 mm (right). The Anderson-Darling test showed that this distance had a normal distribution and Pearson's correlation showed significant reproducibility (P<0.01). The first observer found that 67% of the X-Rays images were suitable for evaluating the anterior glenoid rim. The second found that 81% were suitable and the third 78%. The Kappa coefficient test showed that the second and third observers had substantial agreement of opinion. CONCLUSION: The Bernageau view provided a suitable X-Ray for studying the anterior glenoid rim and for assessing erosion after comparison with the unaffected side
