Summary
This study introduces a novel island osteo-fasciocutaneous flap for thumb reconstruction. This vascularized flap, based on posterior interosseous vessels, successfully restored thumb function in two patients.
Area of Science:
- Plastic Surgery
- Orthopedic Surgery
- Vascular Surgery
Background:
- Thumb reconstruction is crucial for hand function.
- Existing methods may have limitations in providing adequate tissue and bone.
- The posterior interosseous artery offers a reliable vascular supply for reconstructive flaps.
Observation:
- A new island osteo-fasciocutaneous flap design is presented.
- The flap is based on the posterior interosseous vessels, supplying the forearm fascial plexus and extensor muscles.
- A vascularized segment of the ulna, including extensor pollicis longus muscle, can be incorporated.
Findings:
- The described flap successfully reconstructed the thumb in two clinical cases.
- This technique allows for the transfer of well-vascularized bone, fascia, and skin.
- The posterior interosseous artery's territory is well-suited for this type of flap.
Implications:
- This flap offers a viable option for complex thumb defects.
- It potentially improves functional and aesthetic outcomes in thumb reconstruction.
- Further studies can explore the long-term efficacy and versatility of this reconstructive technique.
