- W2049309112 abstract "Long-standing scaphoid nonunion preferentially is treated by using a vascularized bone graft because of its superiority in achieving bone healing. In the present study nonunion was repaired using a bone graft raised from the thumb metacarpal and vascularized by the first dorsal metacarpal artery.Twenty-four patients with scaphoid nonunion for longer than 5 years, without ligament injuries and panarthrosis, had surgery. According to the location of the nonunion and presence of dorsal intercalated segment instability deformity, surgery was performed by either a dorsal or palmar approach. The patients had a final clinical and radiographic evaluation 12 months after surgery.Complete healing was shown in 21 patients but incomplete healing was observed in the remaining 3 patients. After surgery patients had marked pain relief, with an improved range of motion and grasping strength. Anatomic restoration of carpal angles and scaphoid length was observed. None of the patients required additional surgery. Before surgery 15 patients presented radiographic signs of wrist arthrosis. During surgery, however, cartilage erosion on the proximal pole or on the radius articular surface was not confirmed. Despite the presence of radiographic arthrosis, wrist symptoms, motion, and grasping strength improved after surgery.Long-standing scaphoid nonunion, even in the presence of limited arthrosis, can be treated with surgery and healing promoted by a vascularized bone graft. Because of its versatility for use by dorsal or palmar approach and reliability, the first dorsal metacarpal artery vascularized bone graft represents our method of choice." @default.
