In most cases of luxation of the elbow closed reduction constitutes the therapy of choice. Clinical retrospective studies showed signs of arthrosis in 50 % of the cases treated with this therapy, and persisting medial instability after the reduction in more than 50 % of the cases. In the present study the biomechanics of both the medial and the lateral collateral ligaments were analysed after selective severing. Severing of the medial collateral ligament led to an average increase of 30 deg of the pronation with the presence of crepitus on the lateral aspect of the elbow during passive motion. The medial instability of the elbow could be evidenced both clinically and radiographically. Severing of the lateral collateral ligament resulted in an average increase of 15 deg of the supination. Neither palpation nor radiological examination showed any evidence of subluxation
