Objective To observe the curative effect of repairing the distal foot skin and soft tissue defect by using flap.Methods We used nutrient artery flap and low external ankle to repair the foot distal skin soft tissue defect in 16 cases.Results The flap survived,necrosis happened in small skin edge part and distal skin flap of sural nerve nutrient artery flap in two cases,and the skin graft healing with dots after removed the necrotic tissue and changed dressing.16 cases were followed up for 3-16 months,2 cases of flap slightly bloated,1 case back to the hospital got thin skin flap repairing technique;14 cases of walking were as usual,2 lame cases,related to some tissue defect in patients with forefoot injury.The use of flap to repair the foot injury,could maximially recover the limb function,reduce the rate of the sick.Conclusion Skin flap is a kind of operation which is simple,with smaller cost for skin area,beautiful and effective to repair skin and soft tissue defect of foot.

Objective To sum up the surgical characteristics,indications and curative effects of burst fracture by anterior decompression,bone grafting and internal fixation.Methods Since Sep 2004,6 cases with the average age of 32 who were with thoracolumbar spine burst fracture and spinal cord injury of 12-day mean time,were treated with anterior decompression,bone grafting and Z-plate steel plate internal fixation.Before the operation,pateients were classified according to the ASIA classification: 4 cases of grade C,2 cases of grade D;Kyphotic angle(Cobb)15~40?;and vertebral canal 50%~60%.Results The follow-up lasted from 6 to 16 months(average 11 months) and it was found that incision recovered better,no infection of thoracic,abdomen,no grafting loosing or braking occurred.According to the ASIA classification,the functional recovery of spinal cord was 1~2 grade.The Denis assessment showed 5 cases was light back pain,1 case needed medication from time to time but didn't affect the life and work and spine was in order.Conclusion Surgical treatment of thoracolumbar fracture by anterior decompression,bone grafting,internal fixation can provide sufficient decompression,high rate of fusion of the implanted bone,stability in the spine and vertebral body,better recovery of neurological function and satisfied curative effects.It is the best choice for thoracolumbar burst facture and spinal cord injury.
