ObjectiveTo explore the clinical efficacy of minitype vascularized superficial peroneal artery's singleness perforator flap,and then to accurately repair skin and soft tissue defects of hands and foots. MethodsFrom November 2009 to January 2011,eight cases(one case of left foot,one case of right foot,three cases of left hand and 3 cases of right band,1.3 cm × 5.0 cm - 2.5 cm× 6.0 cm of skin and soft tissue defects)were treated by minitype vascularized superficial peroneal artery's singleness perforator flap.Based on preoperative applied anatomy papers, it was the superficial peroneal artery's perforator position in the middle of the lateral lower leg to the fibula head;We designed the flap based on the size and shape of skin defect,and then to analysize the flap design,lap cut,he vascular anastomosis of flap and recipient,effect and characteristics of survival. ResultsAll the flaps(1.5 cm × 5.2 cm-2.8 cm × 6.2 cm) survived and satified in shape and texture, they acquired good functional recovery postoperation;There was blister,dark purple but survival after the scab off on 1 patient;There was phalanx ostomyelitis and healed after treatment on 1 patient.ConclusionThe clinical effects were satisfactory for repairing small skin and soft tissue defect of hands and foots by minitype vascularized superficial artery's singleness perforator flap.
