The purpose of this study was to evaluate the use of a three-dimensional half-ring distraction frame for thumb phalangeal lengthening. From February 2009 to March 2015, 23 patients (23 thumbs) with thumb loss were treated with a half-ring distraction frame. Active movements of the metacarpophalangeal (MCP) joint were measured with a goniometer. These measurements were compared with the opposite hand. Differences were considered statistically significant at p<0.05. Clinical outcome was assessed based on the modified Mayo score. Bone union and good alignment were achieved in all patients. The mean distraction time was 44 days (range, 35-62 days). The mean time to union was 20 days (range, 49-86 days). The mean palmar and radial abduction of the thumb was 60° (range, 53°-65°) and 63° (range, 58°-70°), respectively; on the uninjured side, these measurements were 62° (range, 56°-65°) and 64° (range, 60°-73°), respectively (p>0.05). The mean extension-flexion arc of the MCP joint was 46° (range, 40°-50°); the measurement on the uninjured side was 48° (40°-54°) (p>0.05). The mean follow-up period was 51 months (4.25 years) (range, 48-65 months). The mean modified Mayo Score was 138 (range, 113-145). There were 19 excellent, 3 good, and 1 fair results. The half-ring distraction frame is a viable alternative for thumb lengthening as it provides stable, three-dimensional fixation, resulting in good hand function.
