目的 介绍以膝上外侧动脉或膝最上外侧动脉为蒂的股骨远端皮瓣、骨瓣、骨皮瓣游离移植修复手、前臂远端皮肤软组织、骨及复合组织缺损的方法.方法 在30 侧红色乳胶灌注的下肢标本上,解剖观察了膝上外侧动脉及膝最上外侧动脉的起始、走行、分支、分布及吻合情况,在此基础上设计了以膝上外侧动脉或膝最上外侧动脉为蒂的股骨远端骨皮瓣.结果 应用膝上外侧动脉蒂骨皮瓣3 例、皮瓣1 例、骨瓣1 例,膝最上外侧动脉蒂骨皮瓣1 例、皮瓣2 例.皮瓣面积7.5CM *5 .0 CM ~14.5 CM *6 .5 CM ,骨瓣大小5 .0 CM *1.5 CM *1.2 CM ~6.5 CM *2.0 CM *1.6 CM ,皮瓣及骨皮瓣全部成活,术后3 ~5 个月骨瓣愈合.结论 膝上外侧骨皮瓣,适合于修复手、前臂远端皮肤软组织、骨或复合组织缺损.“,”Objective To introduce the clinical application of the osteocutaneous flap pedicled with the lateral superior genicular artery or the lateral most superior genicular artery in reconstruction of defect of the soft tissue, bone or compound tissue defect on the hand or distal of the forearm.Methods The origin course distribution and an astomosis of the lateral superior genicular artery and the lateral most superior genicular artery were observed on the lower limbs of 30 adult cadavers perfused with pink plastics. The osteocutaneous flap based on the lateral superior genicular artery or the lateral most superior genicular artery were designed according to anatomic study. Results One cutaneneous flap, 1 osteo flap and 3 osteocutaneous flaps pedicled with lateral superior genicular artery were used; the area of the cutaneous or osteo flap were 7.5 cm*5.0 cm-14.5 cm*6.5 cm and 5.0 cm*1.5 cm*1.2 cm-6.5 cm*2.0 cm*1.6 cm respectively; all the flap and osteocutaneous flap survived. Bone union occurred 3-5 months after the operation. Conclusion The lateral supragenual osteocutaneous flap can be used to reconstruct the defect of soft tissue, bone or compound tissue defect on the hand and distal of the forearm.
