title: Treatment of trapeziometacarpal osteoarthritis by partial trapeziectomy and costal cartilage autograft. A review of 100 cases.
abstract: OBJECTIVE
  Trapeziectomy remains the surgery of choice in the treatment of trapeziometacarpal osteoarthritis. Some authors consider the collapse of the trapezial space responsible for a loss of strength and intracarpal deformities. We report our experience of partial trapeziectomy with chondrocostal autograft as an interposition material.
  
  
  METHODS
  The study included100 thumbs in 82 patients with a mean age of 64.6 years (47-82). Mean follow-up was 68 months (4-159). Partial trapeziectomy was carried out through a dorsal approach. The graft was harvested through a direct approach of the 9th rib.
  
  
  RESULTS
  Our results were similar to those obtained with alternative techniques, except for strength where the gain is improved. No intracarpal deformities were seen. There was no sign of graft wear; the length of the thumb ray is preserved. The results are stable over time, and the morbidity of the costal donor site is negligible. The interposition of a hardwearing biological material and its association with partial trapeziectomy enable to restore the thumb stability and strength.
