[Clinical observation of microsurgial repairing for the treatment of soft tissue defection of heel].

Objective: T o summarize the clinical effects of the repairing methods for skin and soft tissue defection of heel.

Methods: From June 1998 to June 2009,42 patients with skin and soft tissue defection of heel underwent the repairing treatment,including 23 males and 19 females, with an average age of 37 years old ranging from 18 to 65. The causes of injuries included mangled injury in 22 cases, high fall injury in 10 cases, cut injury in 5 cases,melanoma in 3 cases, decubital ulcer in 2 cases.

Marrow stromal stem cell autologous transplantation in denervated fracture healing: an experimental study in rats.

Objective: To investigate the influence of bone marrow stromal stem cell (BMSCs) transplantation on healing of fractures combined with central nerve injuries in rats.

Methods: Forty-eight healthy adult SD male rats were randomly divided into the following three groups (16 rats in each group): group A, simple (left) tibial fracture; group B, tibial fracture combined with T10 spinal cord transection (SCT); group C, tibial fracture combined with T10 SCT and BMSCs transplantation. The tibial fractures were stabilized with modular intramedullary nails and all operated hind limbs were further immobilized in plaster casts to prevent unequal load bearing.
