The radial collateral artery perforator (RCAP) flap is a faster and more reliable option for elbow reconstruction compared to the reverse-flow lateral arm flap (LAF). RCAP flaps lead to shorter hospital stays and fewer complications like venous congestion.
Area of Science:
- Microsurgery
- Orthopedic Surgery
- Plastic Surgery
Background:
- The lateral arm flap (LAF) is a viable option for elbow reconstruction, known for minimal donor site morbidity and consistent anatomy.
- Two techniques exist: reverse-flow LAF and radial collateral artery perforator (RCAP) flap.
- This study compares the immediate and long-term outcomes of these two LAF techniques for elbow reconstruction.
Purpose of the Study:
- To compare the functional and aesthetic outcomes of reverse-flow LAF versus RCAP flap for elbow reconstruction.
- To evaluate operative time, healing, and complication rates between the two flap techniques.
Main Methods:
- A retrospective review of 15 patients (9 males, 6 females) who underwent elbow reconstruction using either reverse-flow LAF or RCAP flap.
- Data collected included defect etiology, comorbidities, operative time, healing time, and hospital stay.
- Functional outcomes were assessed using the Quick Disability of Arm Shoulder and Hand (Quick DASH) score.
Main Results:
- Seven reverse-flow LAF and eight RCAP flaps were performed. No major functional limitations or aesthetic dissatisfaction were reported.
- RCAP flap harvest was significantly faster, with shorter hospitalization (P < 0.05).
- Complications included partial RCAP flap necrosis (1 patient) and distal venous congestion in 4 reverse-flow flaps, requiring further intervention in one case.
Conclusions:
- The RCAP flap technique for elbow reconstruction requires less operative time and hospital stay compared to the reverse-flow LAF.
- RCAP flaps are less prone to venous congestion and are recommended over reverse-flow LAF when suitable perforators are present.
- Both techniques offer satisfactory functional and aesthetic outcomes for elbow reconstruction.
