Objectives/Interrogation: The authors performed an autologous cancellous bone graft from the iliac crest and headless compression screw fixation for the treatment of Mack-Lichtman type II scaphoid waist nonunion. The purpose of this study was to determine whether this procedure is effective in achieving bony union and restoration of alignment

Methods: We retrospectively reviewed medical records and radiographs of 36 patients who underwent an autologous cancellous bone graft and headless compression screw fixation for scaphoid waist nonunion. There were 34 men and 2 women with a mean age of 33.1 year-old (range, 22-64 year-old). The mean time to surgery from initial injury was 9.6 months (range, 4-26 months) and the average follow up duration was 32.9 months (range, 12-53 months). The authors analyzed bony union, lateral intrascaphoid angle (LISA), scapholunate angle (SLA), radiolunate angle (RLA), and scaphoid length in radiographs and evaluated the modified Mayo wrist score (MMWS) as a functional outcome.

Results: Bony union was achieved in all cases. The lateral LISA improved from 42° to 31° (P < 0.001). The SLA also improved from 62° to 53° (P = 0.009). The RLA changed from 8° to 4° (P = 0.048) and the scaphoid length changed from 21 mm to 27 mm (P < 0.001) postoperatively. The MMWS improved from 71.2 to 92.0(P < 0.001) significantly at the last follow-up.

Conclusions: Non-structural autologous cancellous bone graft from the iliac crest and headless screw fixation provided reliable results for the treatment of scaphoid waist non-union. This method can be one of the effective treatment options for patients with symptomatic Mack-Lichtman type II non-union in the mid-third of the scaphoid.
