Experimental study on micro replantation repair of rabbit model of the foot skin degloving injury

Abstract

Objective To investigate the replanting the skin under the microscope,the repair of rabbit model of anterior foot application effect of skin degloving injury. Methods 48 New Zealand rabbits,by means of simulation tool cutting avulsion,crush fore foot scene,resulting in the big white rabbit forefoot degloving injury combined with tibia,metatarsal,finger(toe)bone fracture,the establishment of rabbit animal model of the foot skin degloved injury,41 cases were successful,and the use of internal fixation of tibial fracture phalanx or repair of tendon rupture,under the microscope,the artery anastomosis front foot fractureand corresponding nerve,the dorsal skin and set off to the far side,through the direct anastomosis,anastomosed graft bridging method,such asby plane,arteriovenous anastomosis of dorsal,enable the skin to reset,a margin of time a margin of superficial vein anastomosis suture,skin edge,and placed the rubber drainage.Postoperative plaster fixation of rabbit model of the front foot,anti-inflammatory,anti infection. Results 41 cases of rabbit model of skin replantation survived,3cases of wound edge skin a rabbit model of partial necrosis and healed by dressing.Postoperative X-ray review,phalanxtibial fractures of good.The rabbit models were followed up for 3-9 months,average 5 months,fractureand skin wound healed well,the front foot can walk normally. Conclusion In the microscopenext planting the skin,the foot skin repair of degloving injury of the rabbit model,effectively restore the injured foot blood supply,accelerate the healing of fractures,walking function can effectively restore the injured foot in rabbit model.
