Gregory MD and Roy W Sanders MD Abstract Most humeral shaft fractures do not require surgery. When operative stabilization is indicated the surgeon can choose between compression plating and intramedullary fixation. The results after compression plating have been shown to be predictable with respect to healing alignment and range of motion of the shoulder and elbow joints. Although complications are unusual with plate fixation the procedure can require extensive dissection and operative time. Intramedullary fixation offers an alternative to plate fixation with the principal advantage being a limited surgical dissection. This benefit must be balanced against the reportedly high rate of postoperative shoulder problems seen with antegrade nail placement. Unfortunately few direct comparative studies have been done to evaluate the various techniques. The authors attempt to clarify and resolve these issues. J Am Acad Orthop Surg 1997 5 215-223 Humeral shaft fractures are preferably treated nonoperatively most commonly with a functional orthosis. Klenerman1 demonstrated that function of the upper extremity was not affected by as much as 20 degrees of anterior angulation 30 degrees of varus angulation and 3 cm of shortening of the humeral shaft. Sarmiento et al2 showed consistent and rapid healing of 51 humeral shaft fractures treated with the use of prefabricated braces with resultant excellent alignment early restoration of joint motion and minimal morbidity. Balfour et al3 later found similar results in 42 humeral shaft fractures treated with functional braces. Since these reports showing the consistent success of nonoperative treatment appeared authors have strongly recommended closed treatment of humeral shaft fractures unless specific indications for operative intervention exist. Surgical treatment of humeral shaft fractures should be considered for unacceptable alignment with .
