Treatment of fractures adjacent to humeral prostheses.
Fifteen patients with fractures adjacent to a humeral prosthesis were treated between 1986 and 2002. There were 10 females and 5 males. The average age was 58 years. The fractures were classified as to location relative to the prosthesis. Type I fractures (N = 3) occurred proximal to the tip of the prosthesis. Type II fractures (N = 7) occurred in which the fracture line extended from the proximal portion of the humeral shaft to beyond the distal tip of the prosthesis. Type III (N = 5) fractures occurred entirely distal to the tip of the prosthesis. Two type I and 3 type II fractures were managed with a fracture orthosis. The remainder of the fractures were treated surgically with a combination of cerclage wires and long stem prosthesis. All fractures progressed to union at an average of 11 weeks. Average forward elevation for the group was 124 degrees . No patient required a shoulder spica or bone grafting to obtain union. Treatment resulted in fracture union, prosthesis stability, and a paucity of complications.
