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)
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)
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)
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 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)
INTRODUCTION Reconstruction of complex injuries involving bone and soft-tissue in foot remains a tough challenge for surgeons. The free fibular flap is a popular flap for treating these composite defects. However, complications caused by microvascular anastomoses are not uncommon. Herein, we designed a pedicled fibular flap elevated in the ipsilateral leg(More)
BACKGROUND The treatment of chronic calcaneal osteomyelitis remains a challenge for orthopedic and plastic surgeons. The basis of surgical therapy includes thorough debridement of infected tissue and reconstruction with well-vascularized flaps. METHODS A "hybrid" sural flap composed of an adiponeurofascial flap proximally and a neurofasciocutaneous flap(More)
BACKGROUND Management of posttraumatic large soft tissue defects and bone loss remains a therapeutic and surgical challenge for orthopedic surgeons. We assessed the use of a neurocutaneous flap and the Ilizarov technique in the reconstruction of severe composite defects in the tibia. METHODS We retrospectively reviewed 18 consecutive patients with(More)
