The long-term results of resection of the radial head for the treatment of a simple radial head fracture have been generally satisfactory1-5. However, some late complications, such as proximal migration of the radius, can disable the patient and are difficult to treat. Proximal migration of the radius is usually asymptomatic3-5, although wrist pain develops in a minority of patients3-8. The options for treatment are limited, and clinical studies have shown poor and unreliable results9,10. Sowa et al. described a case in which a silicone radial head prosthesis was implanted for the treatment of wrist symptoms10. Proximal migration of the radius progressed, and it was concluded that a more rigid implant would be necessary. Sellman et al. reached a similar conclusion after performing a biomechanical study of this problem11.
We report the case of a patient who had early progressive erosion of the capitellum after the insertion of a metal radial head prosthesis for the treatment of wrist pain following radial head resection after trauma. This complication has not been reported previously, to our knowledge. Our patient was informed that data concerning the case would be submitted for …
