Peripheral nerve regeneration remains a significant clinical challenge to researchers. Progress in the design of tissue engineering scaffolds provides an alternative approach for neural regeneration. In this study aligned silk fibroin (SF) blended poly(L-lactic acid-co-ε-caprolactone) (P(LLA-CL)) nanofibrous scaffolds were fabricated by electrospinning(More)
Large bone defects of extremities, especially those associated with soft tissue defects, represent difficult reconstructive problems. Chimeric flap is a suitable option for reconstruction of complex bone and soft-tissue defects. In this report, we present the experience on use of the peroneal artery perforator chimeric flap for the reconstruction of complex(More)
Many neurotrophic factors have been shown to promote neurite outgrowth by improving the microenvironment that is required for nerve regeneration. However, the delivery of these bioactive agents to the nerve injury site, as well as effective and local release, remains a challenging problem. We have developed a novel composite nerve conduit comprised of(More)
Recent bioengineering strategies for peripheral nerve regeneration have been focusing on the development of alternative treatments for nerve repair. In this study, we incorporated nerve growth factor (NGF) into aligned core-shell nanofibres by coaxial electrospinning, and reeled the scaffold into aligned fibrous nerve guidance conduits (NGCs) for nerve(More)
BACKGROUND The sural neurofasciocutaneous flap has been widely used for reconstruction of soft-tissue defects in the lower leg, ankle, and foot. It can provide a large amount of tissue without compromising the function of the leg. The authors report the applications of the free peroneal perforator-based sural neurofasciocutaneous flap. METHODS The free(More)
BACKGROUND The fibula flap has been widely used for reconstruction of composite bone and soft-tissue defects. The skin paddle of the fibula flap has played a critical role in providing a cutaneous component and good monitor for the bone component. In this report, the authors designed a perforator-based sural neurocutaneous flap instead of a peroneal(More)
The reconstruction of complex soft tissue defects in hands remains a difficult challenge in reconstructive surgery. In this report, we introduce a combined medialis pedis and medial plantar fasciocutaneous flaps supplied by the lateral and medial branches of the medial plantar artery, which allows a one-stage reconstruction of multiple soft tissue defects(More)
The complex wound with the exposed hardware and infection is one of the common complications after the internal fixation of the tibia fracture. The salvage of hardware and reconstruction of soft tissue defect remain challenging. In this report, we presented our experience on the use of the distally based saphenous neurocutaneous perforator flap combined(More)
The distally based superficial peroneal neurocutaneous (SPNC) island flap has been widely used for foot reconstruction. It is based on the descending branch of the peroneal artery perforator. However, damage to the perimalleolar vascularization or anatomic variations of the descending branch often causes flap necrosis. Because septocutaneous perforators(More)
OBJECTIVE To report the operative technique and clinical application of the neurocutaneous flap with anterior cutaneous branch of the femoral nerve supplied by the perforator of saphenous artery. METHODS The reverse neurocutaneous flap with anterior cutaneous branch of the femoral nerve supplied by the perforator of saphenous artery was used for repairing(More)
