Summary
Primary reverse digital artery island flap (RDAIF) reconstruction offers superior outcomes for fingertip injuries compared to secondary reconstruction, especially in older patients. Early intervention maximizes range of motion and minimizes joint contracture.
Area of Science:
- Hand surgery
- Reconstructive surgery
- Microsurgery
Background:
- Reverse digital artery island flap (RDAIF) is a reconstructive technique.
- Outcomes of RDAIF in primary versus secondary reconstruction after failed digital replantation or composite grafting are compared.
- 42 patients (18 primary, 24 secondary) were retrospectively analyzed.
Purpose of the Study:
- To compare the functional outcomes of primary and secondary RDAIF for fingertip reconstruction.
- To identify factors influencing postoperative range of motion and patient satisfaction.
Main Methods:
- Retrospective analysis of 42 patients undergoing RDAIF.
- Evaluation of preoperative demographics and injury details.
- Assessment of postoperative outcomes including joint range of motion, flap sensation, Quick Disabilities of the Arm, Shoulder, and Hand (Quick-DASH) score, and patient satisfaction.
Main Results:
- No significant demographic differences between primary and secondary groups, except for waiting days.
- Similar sensory recovery and patient satisfaction in both groups.
- Primary reconstruction group showed superior range of motion (DIP, PIP, total active motion) and lower Quick-DASH scores.
- Older age, subzone III injury, and secondary reconstruction were associated with poorer range of motion.
Conclusions:
- Secondary reconstruction is linked to a higher incidence of joint contracture.
- Primary RDAIF reconstruction is recommended for fingertip amputations, particularly in older individuals, to achieve optimal functional results.
- Early surgical intervention is crucial for maximizing postoperative range of motion.
