Objective: To investigate the effects of the tension skin flap with different shapes on the transplantation of the reverse neurocutaneous island flap.
Methods: From January 2006 to January 2012,there were 21 patients in the study (including 15 males and 6 females), and aged from 14 to 58 years old (35 years old on average). Tension skin flaps with different shapes (triangle ,round and ellipse) were used to improve the blood supply of the reverse neurocutaneous island flap. The tension skin flaps in the pedicle were designed triangularly (10 patients), spherically (8 patients) or elliptically (3 patients). There were 5 patients with defects in the hand (the size from 5.0 cm x 2.0 cm to 8.0 cm x 5.0 cm), and 16 patients with defects in the foot and inferior segment of leg, or around the ankle (the size from 6.0 cm x 4.0 cm to 13.0 cm x 7.0 cm). And all the patients were with the tendon and bone exposed. All the flaps were reversal transplanted, including 5 dorsal neurocutaneous flaps of foot, 4 superficial peroneal neurocutaneous flaps, 4 saphenous neurocutaneous flaps, 3 sural neurocutaneous flaps, 2 superficial radial neurocutaneous flaps, 3 lateral neurocutaneous flaps of forearm. And the survival rate, appearance and sensory recovery of the flaps were analyzed.
Results: The distant part of the reversed sural neurocutaneous island flap in 1 case necrosized and healed after dressing change. The other flaps survived entirely, and the donor site all healed primarily. The follow-up time was from 3 months to 2 years (averaged 7 months), and all the flaps had recovered pain and warm sensation with perfect appearance.
Conclusion: The tension skin flap in the pedicle can enhance the blood supply and promote survival rate of the reverse neurocutaneous island flap, and can also improve its appearance.

Objective: The surgical team in this study examined the efficacy of a modified reverse sural neurocutaneous flap repair in treating soft tissue defects of the ankle and foot caused by accidents.
Methods: This study enrolled 89 patients treated for soft tissue defects of the ankle or foot between January 2007 and December 2023. The patients were divided into two groups: 44 patients underwent a modified reverse sural neurocutaneous flap repair, while 45 received traditional treatment.

Background: Treating infectious bone defects combined with large soft-tissue lesions poses significant clinical challenges. Herein, we introduced a modified two-stage treatment approach involving the implantation of 3D-printed prostheses and flap repair to treat large segmental infectious tibial bone defects.
Method: We conducted a retrospective study of 13 patients treated at our center between April 2018 and March 2022 for tibial infections owing to posttraumatic infection and chronic osteomyelitis combined with soft tissue defects.

Background: The neurocutaneous flap was developed based on the understanding that every superficial cutaneous nerve includes vessels, also known as vasa nervorum or paraneural vessels, which run around and inside the nerves and deliver blood to the skin above. A cutaneous perforator connected to paraneural vessels that vascularize the skin and nerves is referred to as a neurocutaneous perforator. The lateral antebrachial cutaneous nerve (LACN), the most dependable blood supply from the primary underlying veins of the neurocutaneous flap, is the subject of this study.

Introduction: Malignant tumors of the foot are rare, and treatment strategies are challenging considering the complex anatomy of this area. In recent years, dramatic advances in technology and collaborations between different specialties (such as orthopedic, oncology, radiology, plastic, and vascular surgery) significantly changed the approach to complex malignant tumors without resorting to limb removal. The combination of the strengths of both orthopedic surgery and plastic surgery constitutes the modern definition of "orthoplasty.
