Summary
This study presents a reliable propeller flap technique using the dorsal digital artery perforator flap for fingertip reconstruction. This method ensures good sensory recovery and functional outcomes in patients with fingertip defects.
Area of Science:
- Plastic Surgery
- Reconstructive Surgery
- Hand Surgery
Background:
- Fingertip defects pose a reconstructive challenge.
- Preserving sensation and function is crucial for optimal outcomes.
Purpose of the Study:
- To describe a technique for fingertip defect reconstruction using dorsal digital artery perforator flaps.
- To evaluate the reliability and outcomes of this reconstructive method.
Main Methods:
- A retrospective study of 45 cases (48 digits) involving fingertip reconstruction.
- Utilized dorsal digital artery perforator flaps innervated with proper digital nerve branches in a propeller fashion.
- Flaps were harvested from injured digits, with primary closure of donor sites.
Main Results:
- All flaps survived with minimal complications (two cases of partial epidermis necrosis).
- Good postoperative appearance and texture were observed.
- No significant deficiency in sensory or motor functions, with normal range of motion and no tendon adhesions or scar contractures.
Conclusions:
- The dorsal digital artery propeller perforator flap is a reliable and straightforward option for one-stage fingertip reconstruction.
- This technique effectively restores both form and function in fingertip defects.
