RESUMO
OBJECTIVE: To determine if it is possible to measure glenoid bone loss by using the Bernageau view and to compare it to a 3D CT scan. MATERIALS AND METHODS: Fifty healthy subjects with a mean age of 34 ± 8 years old and 31 (62 %) male were submitted to the Bernageau view X-ray of both shoulders. Three blinded evaluators measured the distance between the posterior and anterior glenoid rim. Ten patients with multiple episodes of unilateral traumatic anterior shoulder dislocation with a mean age of 34 ± 9.1 years old and 90 % male were submitted to the same X-ray technique to determine the percentage of glenoid bone loss. They were also submitted to a bilateral 3D CT scan to be compared to the radiographs. RESULTS: In the 50 asymptomatic subjects, the AP distance was 24.48 mm ± 3.32 mm in the left shoulder and 24.82 mm ± 3.16 mm in the right shoulder. Comparing the X-ray study and the 3D CT scan of the ten patients with multiple episodes, there was no significant statistical difference of the AP normal distance in both methods (p = 0.646), the AP erosion distance (p = 0.386), as well as the percentage of bone loss (p = 0.513). Moreover, the differences between the percentages of bone loss in the X-ray, compared with the 3D CT scan were, on average 2.28 % (range 0 to 6.05 %). CONCLUSIONS: The Bernageau radiographic view is an accurate and reproducible technique for measuring the presence of glenoid erosion, with similar results when compared to the 3D CT scan.

Apresentamos o relato de um caso de lesao da pequena liga no ombro num jovem atleta de 14 anos e do sexo masculino, jogador da selecao Brasileira de Beisebol. Esta lesao é incomum e pouco descrita na literatura. O tratamento realizado foi a suspensao das atividades esportivas por três meses, seguida do retorno gradual aos arremessos. O paciente evoluiu com a resolucao do quadro clínico.
