Abstract

Purpose
This study compared the outcomes of three commonly used reconstructive techniques—the thenar flap, partial toe pulp free flap, and radial artery superficial palmar (RASP) flap—for the reconstruction of fingertip and pulp defects, in order to provide guidance for surgeons in selecting the appropriate method based on defect size and patient characteristics.
Methods
A retrospective chart review was conducted on 50 patients who underwent fingertip or pulp reconstruction. Nine patients received thenar flaps, 26 received partial toe pulp free flaps, and 15 received RASP flaps. Patient demographics, defect size, flap survival, donor site morbidity, and patient satisfaction were analyzed.
Results
All flaps survived. In the RASP flap group, three cases of partial necrosis were successfully managed without additional surgical interventions. The thenar flap group had donor site pain and joint stiffness, while the partial toe pulp free flap group exhibited no donor site complications. The RASP flap group experienced hypertrophic scarring in five cases. Patient satisfaction was high across all groups, with the partial toe pulp free flap yielding the most positive outcomes.
Conclusion
The thenar flap is a reliable option for small defects, especially those with exposed bone, but is associated with donor site morbidity and joint stiffness. The partial toe pulp free flap provides superior functional and aesthetic results for moderate defects, though it requires more surgical expertise and has a longer recovery time. The RASP flap is optimal for larger defects, offering good cosmetic results but requiring careful donor site management to avoid hypertrophic scarring.
