title: The influence of anatomic factors in elbow joint dislocation.
abstract: Twenty-seven patients with elbow joint dislocation were reviewed and treated between 1979 and 1983. For statistical reasons a sample of 27 elbows of healthy adults matched on age and sex were also roentgenographed. A computer-aided analysis of the carrying angle of the arm and the bow angle of the ulnar trochlear notch was made. The stability of the joint was tested clinically. The carrying angle showed no pathologic deviation. Values of the bow angle were at the lower end of the range given in the literature. Referring to these results, only normal anatomic constitutional factors predisposing to dislocation were found. Ligament repair was not routinely performed in this series. Nevertheless, recurrent dislocation did not occur and no relevant instability was detected. Except for injuries with osseous lesions, conservative treatment is advisable in most cases.
