RESTROSPECTIVE ANALYSIS OF 58 CASES OF SCAPHOCARPAL NON-UNION TREATED BY SIMPLE CORTICOCANCELLOUS GRAFT: OUTCOME AT 106 MONTHS

Purpose: The purpose of this retrospective study was to detail factors influencing outcome of corticocancellous grafts for the treatment of scaphocarpal non-union and to determine ideal indications.Material and methods: Between 1984 and 1999, this grafting technique was used for 103 patients; we retained for analysis 57 wrists (58 nonunions). Mean follow-up was 106 months. Mean age was 36 years. For 45 patients, non-union occurred because of misdiagnosis. According to the Schernberg classification, eleven nonunions were in zone II, 40 in zone III, and seven in zone IV. Time from fracture to treatment was 35 months on average. The Alno classification of non-union was: stage I=13, stage IIA=20, stage IIA=22, stage IIIA=2, stage IIIB=1. The graft was harvested from the pelvis in 50 cases. Osteosynthesis was associated with a graft in 33 of the 58 cases. Postoperative immobilisation was maintained for 2.7 months on average. Bone healing was achieved within thee months.Results: Thirty-six patients were very sa...
