RESUMEN
Forty patients with symptomatic nonunion of the scaphoid had been treated with pronator quadratus pedicled bone graft in the period from 1997 to 2000. The patients were presented and treated at both Army Force Hospitals and Kasr El-Aini Hospital. The patients presented with pain, tenderness in the anatomical snuff box, limited range of motion and weak hand grip strength. The average time before operation was 21.2 months [6 to 60 months]. Fractures with distinct fracture line, sclerotic margins with or without cyst formation were considered as un-united fractures. Two patients had distal third fractures, 28 patients had waist fracture and the remaining 10 patients had proximal third fracture. Eight patients had dense X-ray appearance of the proximal fragment. After an average follow-up of 12 months [range from 6 to 19 months], 28 patients united and 12 patients failed to unite. Four out of eight cases with sclerotic proximal fragment united
