Objective: To clinically evaluate patients with combined distal thumb lesions treated by a dorsolateral flap or radial midpalmar island flap. Materials and Methods: We retrospectively compared 20 patients (14 males and 6 females, averaging 35 years) with combined distal thumb traumatic lesions, who were operated on by two surgeons using different techniques. Patients had no pre-vious surgical history and a minimum follow-up period of 24 months. Subjective outcome was evaluated by satisfaction index (SI), visual analogue scale (VAS), and QuickDASH score. Objective outcome was evaluated by two-point discrimination test (TPDT), average surgical time (ST), and need for digital spatial reeducation (DSR). Results: Time from admission to medical discharge averaged 7 weeks (range, 6-8). Average postoperative results: VAS for pain, 01/10 (both groups); IS, 97% vs. 92% (dorsolateral flap group vs. radial midpalmar island flap); TPDT, 4 mm vs. 6 mm; QuickDASH, 2.5 vs. 8; ST, 45 minutes vs. 60 minutes; need for DSR, 0 vs. 4 cases. Conclusion: Both the dorsolateral flap and the radial midpalmar island flap techniques were effective in the treatment of distal thumb traumatic lesions, although the dorsolateral flap achieved better objective evaluation scores and required less ST.
