摘要目的 探讨应用髂腹股沟嵌合穿支骨皮瓣修复四肢骨和软组织缺损的临床方法 和疗效.方法 2004年5月至2018年2月,对11例骨不连或骨缺损伴软组织缺损的患者,应用以吻合旋髂浅动脉为蒂的嵌合穿支骨皮瓣修复7例,应用以吻合旋髂深动脉为蒂的嵌合穿支骨皮瓣修复4例.骨瓣切取大小为2.5 cm×2.0 cm×2.0 cm～6.0 cm×3.0 cm×2.0 cm,皮瓣切取大小为5.0 cm×3.0 cm～17.0 cm×13.0 cm.皮瓣供区均逐层严密直接缝合.术后对9例患者进行回院随访,观察皮瓣的外观、质地、色泽、浅感觉、骨折愈合情况、患肢功能恢复情况及供区情况.结果 本组皮瓣术后全部成活.9例术后随访3～18个月,受区皮瓣外形良好,质地柔软,色泽与受区相近,骨折断端均骨性愈合,患肢功能恢复良好,掌骨缺损处掌指关节、掌腕关节活动无受限,步态正常,步行无疼痛,皮瓣供区除1例稍增生,余仅留线状瘢痕,无腹壁疝发生,大腿无麻木不适感.结论 髂腹股沟嵌合穿支骨皮瓣修复四肢骨和软组织缺损,根据骨缺损大小选择切取不同血管蒂带血供的髂骨移植并修复创面,供区隐蔽、创伤小,骨折愈合快,手术体位操作方便,疗效满意.

abstractsObjective To evaluate the method and clinical efficacy of utilizing ilioinguinal chimeric perforator bone flap to repair bone and soft tissue defects of limb.Methods From May,2004 to February,2018,there were 11 patients who were diagnosed as bone and soft tissue defect in the upper or lower extremities,7 of which were repaired by chimeric perforator bone flap with the superficial circumflex iliac artery and 4 of which were repaired by chimeric perforator bone flap with the deep circumflex iliac artery.The size of bone flap ranged from 2.5 cm×2.0 cm× 2.0 cm to 6.0 cm×3.0 cm×2.0 cm,and the flap sizes ranged from 5.0 cm×3.0 cm to 17.0 cm×13.0 cm.The donor sites of the flap were directly sutured.Nine patients were implemented by postoperative followed-up visit in hospital.And the appearance,texture,color,shallow sensation of flaps,fracture healing,limb's function and donor site were observed.Results Postoperative followed-up ranged from 3 to 18 months.All flaps survived.The flaps had satisfactory appearance,texture and color.Osseous tissue of defects healed.The function of injury limb was restored well,which metacarpo-phalangeal joint and carpometacarpal joint's movement with metacarpal defect recovered,and gait were normal without pain.As for the donor sites,1 case had hyperplastic scar while the other only had linear scars.Abdominal hernia and numbness with lower extremities were disappeared.Conclusion Ilioinguinal chimeric perforator bone flap can be designed with different pedicles based iliac bone flap according to the size of bone defects.The donor site is concealed with less trauma and less healing time.The operation position is easy to operate,and clinic efficacy is satisfactory.
