Aims: There is a resurgence of interest in hip resurfacing. To date, our own unit has treated 60 patients (65 hips) with the Corin hip resurfacings. Between Jan 99 and July 02, 12 of these patients required early revision surgery. Methods: Retrospective study. Results: The indication for revision was fractured neck of femur in þve cases. 4 of the 5 fractured neck of femurs cases occurred within 6 months of the primary procedure. There were 4 cases of loose acetabular components and one case of progressive avascular necrosis. One patient required revision surgery for ongoing hip pain and one required a two stage revision for early deep infection. Conclusions: In the DGH environment, resurfacing may be associated with a high revision rate with a signiþcant learning curve.

We reviewed 55 patients (78 feet) who had undergone silicone hemiarthroplasty of the first metatarsophalangeal joint for hallux valgus (40) or hallux rigidus (38). At a mean period of 4.5 years (1 to 11), 56 feet had radiological evidence suggestive of silicone granulomatous disease. The frequency and severity of the changes increased with time from the operation. Histological material from three revisions confirmed the presence of silicone granulomata. We recommend that the operation of silicone hemiarthroplasty for hallux valgus and hallux rigidus be abandoned.
