INTRODUCTION: There are many types of intrinsic flaps to cover wound defects on the hand, which have been well described in scientific literature. However, the donor sites are often neglected in such studies. Therefore, we aimed to evaluate donor site morbidity for homodigital island flaps, cross-finger flaps, Foucher's pedicle flaps, and flaps of the dorsal metacarpal artery system (DMCA). MATERIALS AND METHODS: A total of 106 intrinsic flap procedures were performed on 106 patients (16 women, 90 men). The donor sites were retrospectively followed up after an average of 3.4 years by a questionnaire, a Disability of the Arm, Shoulder and Hand score, and clinical examination. Donor sites of different flap types were compared for aesthetic outcome, trophic level, and sensation, including 2-point discrimination, temperature, sharp/dull discrimination, the Semmes-Weinstein monofilament test, pain (visual analog scale), and functionality. RESULTS: In general, primarily closed donor sites showed more favorable results than did grafted donor sites. Satisfaction among patients regarding aesthetics of the donor site was highest in patients who had received homodigital island flaps. Grip strength and pain at the operated hand were very heterogeneous and rather influenced by the primary trauma than the type of flap. Homodigital island flap donor sites demonstrated the best results for 2-point discrimination and sharp/dull discrimination, and those for DMCA flaps in the Semes-Weinstein test. CONCLUSIONS: Overall, intrinsic flaps demonstrated low donor site morbidity with reliable coverage of the defects. Of these, the DMCA (especially after primary closure) and homodigital island flaps seemed to produce the best donor site results.      «
