Mean patient age at surgery was 22.5 years. Average time from injury to surgery for nonunion was 18 months. In 5 cases, mild signs of osteoarthritis of the radioscaphoid joint (scaphoid nonunion advanced collapse [SNAC] stage I) were present before surgery, and in 2 cases, radiographic signs of avascular necrosis of the proximal nonunion fragment were evident. In all cases, a corticocancellous nonvascularized bone graft taken from the distal part of the ipsilateral radius was used. Mean follow-up was 11.2 years. Nonunion had healed in 93.1% of cases. At follow-up, the 2 patients in whom nonunion had not healed had severe painful osteoarthritis of the wrist (SNAC stage IV). Twenty patients were asymptomatic, and 5 had occasional pain in the wrist. Wrist range of motion was restricted in all patients compared with the contralateral side. Mild osteoarthritis was observed in 6 patients (SNAC stage I). The average Disabilities of the Arm, Shoulder and Hand score was 8.7 of 100. The modified Murray technique is reliable for treating nonunion of the carpal navicular. The union rate is high, and the incidence of wrist osteoarthritis is low compared with other studies. Early diagnosis and treatment of nonunion (a short interval between fracture and surgery) can minimize the risk of degenerative joint disease. Avascular necrosis of the proximal fragment is not an absolute contraindication to surgery.
