    Abstract:
    PURPOSE: Resection of the underdeveloped digit and reconstruction of the robust digit is the standard treatment option for preaxial polydactyly of the hand. As an underdeveloped digit, the radial component is usually excised, whereas the ulnar component excision is rarely needed. This study aimed to evaluate the surgical results of ulnar component excision and radial component reconstruction in patients with preaxial polydactyly of the hand. METHODS: We retrospectively reviewed the medical records and radiographs of 809 patients (861 thumbs) who underwent surgery for preaxial polydactyly of the hand from November 2006 to June 2018. Among these, 22 (2.6%) thumbs in which the ulnar component was more hypoplastic or had more severe deformities than the radial component were treated with ulnar component excision and radial component reconstruction. The mean follow-up duration was 49 months (range, 12-142 months). We evaluated the Japanese Society for Surgery of the Hand scores and whether the patients were satisfied with the thumb function and appearance at the final follow-up. We also recorded any complications, such as reoperation. RESULTS: The mean Japanese Society for Surgery of the Hand score was 12.8 (range, 5-17). Six patients had poor results, 7 had fair results, and 2 had good results; however, none of the patients had an excellent result. Satisfaction with thumb function and appearance was reported in 11 (50%) and 6 (27%) cases, respectively. Thirteen of 22 (59.1%) cases involved reoperations, and the most common reason for reoperation was interphalangeal joint deviation of the remaining thumb. CONCLUSIONS: Ulnar component excision and radial component reconstruction are rare operative choices in preaxial polydactyly of the hand. Surgeons and patients should be aware that a considerable number of patients treated with this method required reoperations and had low clinical outcome scores. TYPE OF STUDY/ LEVEL OF EVIDENCE: Prognostic IV.
