title: Arthroscopical Findings after Antegrade Nailing of a Proximal Humeral Fracture : Case Report and Review of the Literature.
abstract: Proximal humeral fractures represent up to five percent of all fractures in adults, commonly found in elderly patients. The final functional results after different operative procedures are among other factors dependent on whether or not a rotator cuff lesion is pre-existent, prior to the fracture, and how its surgical therapy is carried out. However, to what extent prior rotator cuff tears in this special patient group contribute to the functional outcome remains widely unclear. In our institution antegrade intramedullary nailing is the treatment of choice for proximal humeral fractures. One critical point of this technique is the unavoidable split of the rotator cuff on the approach to the proximal humerus and the insertion of the nail through the incised cuff. We report on a case of an impingement after antegrade intramedullary nailing of a proximal humeral fracture. Diagnostic glenohumeral arthroscopy revealed neither a residual lesion of the former rotator cuff incision nor a chondral lesion at the former insertion site of the nail. In the same session subacromial decompression and a nettoyage of adhesions were performed. We assume that splitting the rotator cuff for the insertion of an antegrade nail in a proximal humeral fracture is less relevant than previously assumed and described.
