Objective To investigate the use of free transplantation of peroneal artery perforator-based propeller to the repair of the front feet skin defect.Methods Thirteen cases with front foot skin defect patients repaired through transplation of propeller flap of the peroneal artery from January 2009 to September 2012.The wound range was 5 cm ×4 cm-11 cm × 14 cm.The propeller flap of the peroneal artery designed according to the position of the propeller of the peroneal artery in a leg.The wound of the leg were repaired through suture directly or transplantation of skin.Results All 13 cases of free propeller flap were survived,the wound healing goodly.One case with the postoperatie blood vessels were removed by the surgical exploration.The time of follow-up between 3 and 17 months(mean 9.4 months).The quality of free flap was good.The function of walk of the foot repaired were not significantly affect.The patients were satisfactory to the results.The wound of the leg healed well ; The leg had no obvious muscle cicatricial adhesion.According to the foot disease treatment effect evaluation standard (JOA) evaluation,the result for 77-100 points,an average of 85.5 points.Conclusion Using propeller flap of the peroneal artery to repair the skin defect of front feet with a little injury,the skin texture more close to the repaired area,it is a reasonable approach.

Objective To explore the curative effect of fibular flap with limbs composite soft-tissue.Methods From February,2013 to February,2016,13 cases with body severe trauma patients were treated,which including 5 cases of upper limbs and 8 cases of lower limbs,and all existed bone defect,soft tissue defect and trunk vessel defect.Three cases with limbs distal non blood supply were emergency treated with debridment and flow-through fibular flap transplantation renovation,peroneal artery repairing defective blood vesscls to rcstorc limbs distal blood supply,fibular flap repairing bone defect,skin flap repairing soft tissue defect.The limb blood supply for other 10 cases were in good condition,but one case with main artery defect did the second phase of fibular flap transplantation and repaired defective blood vessels,bone and skin soft tissue synchronously according to wound condition.According to the postoperative observation for flap survival and appearance,X-ray films to observe fracture healing after 6 weeks,three months and 6 months of operation as well as evaluating limb function recovery,then analyzed the results.Results Flaps survived successfully for 11 cases,and flaps for the other 2 cases were partial necrosis.One Case was edge flap necrosis,heal scabby after dressing,and the other case was necrosis for 1/3 of the area,but the deep fascia survival,and the skin graft healing after dressing.One case with forearm rolling was in vascular crisis after operation,but tbe crisis was relieved after detection,and fingers blood supply was recovered.All the patients were followed up for 6 to 36 months(mean,14 months).All flaps were survived,fractures healed well and limbs distal blood supply was good.Bone healing time was 8 to 24 weeks,and patients with lower limbs injury could bear load after 3 to 8 months.Lower limbs restored walking function.Upper limbs and hands restored rotation function.Transplant flapshad good elasticity and satisfactory appearance.Conclusion Using fibular flap to repair defective blood vessels,bone and soft tissue synchronously,not only can rescue the limbs on the verge of amputation,but also can repair defective composite tissue and get a good prognosis.It is an effective method for open injuries severely treatment in clinic.

Objective To investigate the clinical effect of infective foot ulcer and soft tissue defects of small area with free peroneal artery perforator flap.Methods From February,2016 to Apirl,2017,9 cases of infective foot ulcer and soft tissue defect of small area were repaired with peroneal artery perforator flap.Cause of infection:injury in 6 cases,diabetes in 2 cases,spinal cord injury subsequent pressure sore in 1 case.Infective ulcer part:4 cases on plantar metatarsophalangeal joint,2 cases on dorsal metatarsophalangeal joint,2 cases on interior of the first metatarsophalangeal joint and 1 case on the heel.Defect area:3.0 cm×2.0 cm-5.0 cm×3.0 cm;flap area:4.0 cm×3.5 cm-7.0 cm×4.5 cm.The donor sites were sutured directly.All the flaps contained lateral sural cutaneous nerve.In order to rebuild the sensation of flaps,nerves between surgical area and receiving area were received end-to-side anastomosis.Outpatient follow-up was used in all patients.Results All the flaps survived,and all the wounds were primary healed,without recurrence of infection.All patients were followed-up from 6 to 24 months with an average of 16 months.The appearance of flaps was good with slight bloated.The texture and color of the flaps were close to the recipient site.Flap feel was good except the cases of diabetes and spinal cord injury pressure sore.The AOFAS score at last follow-up time was 80.05±7.80,which was excellent in 5 cases,good in 2 cases,and fair in 2 cases.Conclusion The free peronerl artery perforator flap has many advantages,such as vascular anatomy constant,blood supply is reliable,thickness moderate,easy to get,strong resistance to infection,small district damage,etc.It is a useful clinical method to repair foot infection ulcer and soft issue defects of small area.

Objective To explore the clinical application and effect of fibular head compound soft tissue flap transplantation on precision repairing of compound tissue defect at limb joints assisted by 3-Dimensional contrast printing technology.Methods From March,2014 to September,2017,9 patients with bone and soft tissue defect at limb joints were selected.In which,2 were distal radius bone defect with joint capsule and ligament defect,2 were lower segment tibia bone and soft tissue defect,2 were femur under section of the bone and soft tissue defect,2 were medial malleolus bone and ligament defect,and 1 was external ankle ligament and bone defect.Using 3-Dimensional printing to conduct bilateral mirror-image contrast prior to the operation,morphology of bone defect at limb joints was acquired.Based on the texture printed out,corresponding fibular head compound blocks with blood vessels were removed from the donor site and transplanted to the recipient site before anastomosing the blood vessels and restoring the blood flow.The regular post-operative followed-up was performed.Results The 9 transplanted tissue blocks survived.The donor sites and the recipient sites were healed.The followed-up for restoration of limb function was from 9 to 35 (average,17.5) months.The ankle function was assessed according Kofoed scale,resulted in 2 excellent and 1 good;The wrist function was assessed according Mayo scale,resulted in 1 excellent and 1 good.The medial malleolus bone defect and criteria bone defect were healed at 6 months.The patients were satisfied with the efficacy.Conclusion The application of 3-Dimensional contrast printing of fibular head compound tissue flap transplantation in repairing compound tissue defects at limb joints can reduce damage to the donor site,realizing precise repairing on limb tissue defect,and make good function restoration.

Objective To explore the method of limb salvage therapy for hand and foot destructive injury, and to clarify the role of free tissue transplantation in limb salvage therapy in patients with hand and foot destructive injury. Methods From January, 2015 to January, 2016, 17 hand and foot destructive injuried patients were treated with limb salvage. The anterolateral thigh free flap, free fibular flap and arterial vein flap were used to repair the skin, soft tissue and bone defects. All patients were followed-up for 12 months. The appearance and function of the patients were evalu-ated after the treatment. The hand scoring criterion was the finger replantation function evaluation standard on probation of the Chinese Medical Association of Hand Surgery. The foot scoring criterion was the Maryland score system. Re-sults All flaps survived in 17 patients. One flap had vascular crisis after operation, and survived after vascular ex-ploratory operation. One case had infection postoperation and healed after several debridements. After 12 months, the functional scores were excellent in 5 cases, good in 5 cases, moderate in 3 cases and poor in 4 cases. Conclusion The early repair with free tissue transplantation can preserve limb length, cover the exposed bone and tendon, and improve the anti-infective ability, so as to improve the function of limb salvage and patient 's satisfaction.

Objective:To investigate the effects of types of ulnar styloid process fracture on the treatment of distal radius fracture.Methods:The 80 patients were analyzed retrospectively who had been treated at The First Department of Hand Surgery, Honghui Hospital from January 2019 to January 2020 for fracture of distal radius complicated with fracture of ulnar styloid process. They were 25 males and 55 females, aged from 30 to 85 years (average, 58.6 years). According to the types of ulnar styloid process fracture, 40 patients were assigned into a Hauck type Ⅰ group and the other 40 into a Hauck type Ⅱ group. The 2 groups were compared in terms of operation, postoperative complications, hospital stay, bone union, visual analogue scale (VAS) on postoperative 1 to 3 days, and modified Mayo wrist function score, wrist range of motion and quality of life by WHOQOL-BREF at the last follow-up.Results:The 2 groups were comparable because there was no significant difference in age, gender, American Society of Anesthesiologists (ASA) rating, or time from injury to operation between them ( P>0.05). All the patients were followed up for 12 to 24 months (average, 17 months). There was no significant difference between Hauck type Ⅰ group and Hauck type Ⅱ group in operation time, intraoperative blood loss, hospital stay, rate of postoperative complications, fracture union, modified Mayo wrist function score or VAS on postoperative 1 to 3 days ( P>0.05). At the last follow-up, the palm tilt and ulnar inclination angles were 13.8°±1.9° and 21.6°±2.8° in Hauck type Ⅰ group, significantly larger than those in Hauck type Ⅱ group (11.9°±1.6° and 18.8°±2.3°) ( P<0.05). At the last follow-up, Hauck Ⅰ group scored 85.3±6.4,85.6±6.5, 84.7±6.3 and 85.0±6.7 respectively in the domains of physical health, psychology, environment and social relationships, significantly higher than those Hauck type Ⅱ group did (78.5±6.5, 78.9±6.5, 77.8±6.1 and 77.9±6.3) ( P<0.05). Conclusions:In open reduction and internal fixation for distal radius fracture, Hauck Type Ⅰ fracture of ulnar styloid process has no significant effect on the functional recovery of the wrist but Hauck Type Ⅱ fracture of ulnar styloid process may. Therefore, surgical fixation needs to be strengthened if Hauck Type Ⅱ fracture of ulnar styloid process is complicated.
