    Objective: The objective of this study was to analyze elbow injuries and their probable mechanism in Jiu-Jitsu fighters resulting from the armbar-type armlock. Methods: We evaluated 5 high-performance Jiu-Jitsu fighters from the Gracie Elite gym who were injured during a tournament. All were healthy males with a mean age of 28.8 years. The right arm was involved in three patients (60%). The athletes were followed for approximately 4.6 months, and pain was present in all cases. Clinical examination of the elbow was performed immediately after the injury and when magnetic resonance imaging (MRI) was performed. The radiography showed no changes. Clinical examination detected specific tender points on the medial and anterior topography of the elbows, but no ligamentous instability of the elbow was seen during dynamic testing. Results: The main MRI findings were injury to the common flexor tendon and the ulnar collateral ligament, bone contusion of the distal humerus and olecranon, and joint effusion. Conclusion: The main pattern of injury indicated by the MRI in the athletes was injury to the medial elbow complex. The primary mechanism that determined the injury was most likely elbow hyperextension applied with the forearm in neutral position of forearm.

    Evolução etária do ângulo de carregamento do cotovelo: estudo clínico-radiográfico
    (Sociedade Brasileira de Ortopedia e Traumatologia, 2011-04-01) Terra, Bernardo Barcellos [UNIFESP]; Silva, Bruno Costa Mello [UNIFESP]; Carvalho, Henrique Bella Freire de [UNIFESP]; Dobashi, Eiffel Tsuyoshi [UNIFESP]; Pinto, Jose Antonio [UNIFESP]; Ishida, Akira [UNIFESP]; Universidade Federal de São Paulo (UNIFESP)
    OBJECTIVE: This paper has the purpose of evaluate the elbow carrying angle by clinic and radiographic examination in normal children and determine the range of normality according to age from childhood to skeletal maturity and also check if there is a statistically significant difference between the clinical and radiographic measurements. METHODS: We evaluated 510 persons with ages varying from 1 to 18 years distributed in groups with 30 subjects according to the age group with 1-year interval. We performed radiographic examination of the elbow and measured the angle formed by the long axis of the humerus and ulna. The data were statistically analyzed using the student t-test. RESULTS: We determined a normal curve of the study population where there was an increase of this parameter with the progression of age. No statistically significant difference between the clinical and radiographic measures. CONCLUSION: The average of the elbow carrying angle was 12,78 ± 5,35 degrees for females and 11,20 ± 4,45 degrees for males. This values increase progressively from childhood until 16 years when we notice stabilization. There was no statistical difference between the clinical and radiographic measurements.
