Sixteen Swanson trapezium silicone prostheses are reviewed retrospectively an average of 3 years after insertion. Fifteen were performed for osteo‐arthritis and one for rheumatoid arthritis. Despite a very high patient satisfaction, 14 thumbs had residual functional compromise and caused pain when performing certain tasks. Three implants were completely dislocated and another four were significantly subluxed. One patient required implant removal. Intra‐osseous cysts or significant bony erosion around the implant were present in five thumbs. It is concluded that there are early significant problems associated with this procedure which make it unsuitable for use in the osteo‐arthritic thumb.
