[A comparative study of the treatment of fractures of the radial head by resection or by Swanson silastic implant].

The authors report 62 fractures of the head of the radius treated either by excision or silastic implant arthroplasty. Fifty-two patients were reviewed with a mean follow-up period of 5 years (range 1 to 13). Of 22 prosthetic replacements, 12 were satisfactory while of 30 excisions only 10 were rated good or excellent. Excision usually yielded valgus deformity of the elbow (range 9 to 35 degrees) and with a risk of shortening of the radius. Range of flexion-extension was identical after both procedures but pronation supination was better after prosthesis replacement (78/70) than after radial head excision (65/60) 3 fractures of the implant were found at 6, 9 and 10 years postoperatively; only one of them was associated with pain and required removal of the loose fragments.
