摘要目的:探讨以旋髂浅动脉浅支为蒂的嵌合皮瓣修复手背部软组织合并掌骨缺损的治疗效果。方法:自2015年5月至2022年1月,宜宾市第三人民医院骨科共收治手背部软组织合并掌骨缺损患者34例,男28例,女6例；年龄22~51岁,平均37岁。清创后软组织缺损面积2.5 cm×5.0 cm~4.5 cm×9.0 cm,缺损部位均位于手背部及腕背侧,骨缺损长度1.8~4.1 cm；均是单根掌骨缺损,其中第1掌骨缺损14例,第2掌骨缺损7例,第3掌骨缺损4例,第4掌骨缺损8例,第5掌骨缺损1例。均采用旋髂浅动脉浅支为蒂的嵌合皮瓣修复,皮瓣面积为3.6 cm×5.4 cm~5.2 cm×9.5 cm。术后予以抗凝、保温以及石膏固定4~6周；术后患者均采用门诊、电话或微信的形式随访,随访内容包括受区皮瓣感觉和外观、供区愈合情况及手部功能恢复情况。结果:34例嵌合皮瓣全部成活。术后随访3~15（平均10）个月,髋部供区切口均Ⅰ期愈合,皮瓣TPD 5.1~7.3 mm,平均6.4 mm；受区皮瓣外形满意,无臃肿,腕关节和掌指关节活动能满足基本活动需求。掌骨缺损骨愈合时间2~3个月,平均2.8个月。手部功能按照中华医学会手外科学会上肢部分功能评定试用标准评定优6例、良28例。结论:旋髂浅动脉浅支为蒂的嵌合皮瓣是修复手背部软组织合并掌骨缺损的理想方法,具有供区损伤小、皮瓣血运丰富、手术切取简单、一期同时修复软组织及掌骨缺损等优点。

abstractsObjective:To investigate the effect of chimeric flap pedicled with superficial branch of superficial iliac circumflex artery in repair of soft tissue defect of dorsal hand combined with metacarpal bone defect.Methods:From May 2015 to January 2022, 34 patients(28 males and 6 females) of soft tissue defects of dorsal hand with metacarpal bone defects were treated in the Department of Orthopedics of Yibin Third People's Hospital. The age of patients ranged from 22 to 51 years old, with an average age of 37 years old. The areas of soft tissue defects after debridement were 2.5 cm×5.0 cm-4.5 cm×9.0 cm, and the defects were all in dorsal hand and dorsal wrist. The lengths of metacarpal bone defect were 1.8-4.1 cm. All the patients had only single metacarpal bone defect, among which: 14 patients had defects in first metacarpal bone, 7 in second metacarpal bone, 4 in third metacarpal bone, 8 in fourth metacarpal bone and 1 in fifth metacarpal bone. All the patients were repaired by chimeric flap pedicled with superficial branch of superficial iliac circumflex artery. The size of flaps were 3.6 cm×5.4 cm-5.2 cm×9.5 cm. Anticoagulation, thermal preservation and plaster fixation were applied for 4-6 weeks after surgery. Postoperative follow-ups included regularly outpatient clinic visit, telephone or Wechat reviews. Follow-up items covered: the feeling and appearance of flaps in recipient sites, healing of the donor sites and recovery of hand functions.Results:All the 34 chimeric flaps survived. Regular follow-up lasted for 3 to 15(average, 10) months. All incisions in the donor sites of hip healed in stage I. TPD of the flaps was 5.1-7.3(mean, 6.4) mm. Appearance of flaps in the receiving area were satisfactory without swelling. Movement of wrists and metacarpophalangeal joints met the basic requirement of movement. The healing time of metacarpal defect was 2-3 months with an average of 2.8 months. Hand functions were evaluated at excellent in 6 patients and good in 28, according to the Evaluation Standard of Upper Limb Partial Functional of Hand Surgery of Chinese Medical Association.Conclusion:The chimeric flap pedicled with superficial branch of superficial iliac circumflex artery is an ideal flap to repair the soft tissue defect in dorsal hand combined with metacarpal bone defect. It has advantages of less donor site damage, good blood supply of flap, simple surgical procedure, and one-stage repair of a combined soft tissue and metacarpal bone defects.
