A comparison between reversed cross-finger flap and Quaba flap in reconstruction of proximal dorsal digital defects

Background
The aim of the study is to compare between reversed cross-finger flap and Quaba flap in reconstruction of proximal dorsal digital defects. The hand is an important part of the body with unique characteristics that plays an indispensable role in human life. Soft-tissue defects and deformities of the hand are caused by trauma, burn, infection, and tumor. These defects if not managed properly can cause a temporary or permanent disability in the hand.
Patients and methods
This cohort prospective study was conducted at Menoufia University Hospitals from January 2018 to January 2020, with a follow-up of 6 months. The population of the study was 43 patients with proximal dorsal digital defects. We divided the cases into two groups: the first underwent reversed cross-finger flap and the second underwent Quaba flap. Follow-up was done over 6 months regarding donor and recipient site functional and esthetic outcomes.
Results
This study was done on 43 patients: 22 (51%) patients underwent Quaba flap and 21 (49%) patients reversed cross-finger flap. Thirty-seven (86%) patients in our study had posttraumatic defects and six (14%) patients had postburn deformity on dorsum of fingers. There was a statistically significant difference in incidence of complications between the two groups, in favor of Quaba flap.
Conclusions
Both reversed cross-finger flap and Quaba flap are reliable for treating small to moderate site defects and deformities on the dorsum of the fingers up to distal interphalangeal joint (DIP). However, Quaba flap has limited donor site impairments, such as contour defect and movement restrictions, in contrast to reversed cross-finger with better functional and esthetic outcome.
