Clinical effects of emergency primary repair for severe crush injury of forearms with chimeric transplantation of the lateral femoral muscle superficial region
Objective To investigate the feasibility and clinical effects of chimeric transplantation of the lateral femoral muscle superficial region to repair severe crush injury of forearms.Methods From May 2012 to March 2022,emergency primary repair of severely injured forearms caused by crush in 30 cases in Department of Hand and Podiatric Microsurgery,Xi′an Fengcheng Hospital was carried out.Bilateral or unilateral comminuted fractures of the ulna and radius,skin defects,or combined injuries of blood vessels,bone and muscle tissues were found in all of the patients.Wound covering,muscle tamponade,reconstruction of muscle dynamics and bone repair were performed.Patients were followed up every 3 months after surgery through reexamination,phone or WeChat,recorded the flaps looked and sensory function,bone healed and the functions of forearms and hands.Results The forearms of 28 cases were treated,and the limb salvage rate was 93.33%.Exploration of blood vessel was conducted in 7 cases.The number of operations was1-5,with an average of 2.6.The infection rate was6.67%.The bone healing time was3-10 months,with an average of 6.7 months.According to the Anderson score,the rate of excellent and good outcomes of surgery was 71.4%at 6 months after surgery.The average score of the disabilities of the arm,shoulder and hand(DASH)questionnaire was 34.2.Conclusion The chimeric transplantation of the lateral femoral muscle superficial region used to repair the combined injuries of forearms caused by the severe crush,can increase the limb salvage rate,and restore some functions of the forearms.
