Radial Head and Neck Allograft for Comminute Irreparable Fracture-Dislocations of the Elbow.
Fracture-dislocations of the elbow can be difficult to treat, with unsatisfactory results in some cases. In general, it is preferable to preserve the fractured radial head when possible, but some patients present a unique treatment challenge because of extremely comminuted fractures and bone loss. In these cases, the only options available are radial head prosthesis or allograft. The authors present a case of a 45-year-old man with a fracture-dislocation of the left elbow that was treated with an allograft of the radial head and neck because of extreme comminution of the fracture. There have been a few reports about osteochondral allograft transplantation of the radial head, and they all included traumatic or posttraumatic cases treated with a frozen allograft. To the best of the authors' knowledge, this is the first report on the use of osteochondral allograft in the acute setting for the treatment of a comminuted fracture of the radius involving the whole head and neck. The clinical results were satisfactory at the final follow-up, although mild degenerative changes were present, the screws were coming loose, and the radial head had a slight valgus deformity. Radial head allograft can be an option in selected cases of acute fractures with severe comminution and bone loss that are not amenable to a stable internal fixation; for the young and active patient, who is not the best candidate for radial head resection; or in cases in which radial head arthroplasty is not feasible because of severe bone loss.
