摘要:
目的 探讨足底内侧动脉穿支皮瓣移植整复手部掌侧瘢痕挛缩的效果。 方法 该研究为回顾性观察性研究。2016年1月—2023年1月, 广州和平骨科医院收治15例符合入选标准的手部掌侧瘢痕挛缩患者, 其中男12例、女3例, 年龄15~50岁。术前患手功能密歇根大学手概况问卷调查表(MHQ)得分为58~77分, 患手总主动活动度为190~220°。患手掌侧瘢痕切除后皮肤软组织缺损面积为5.2 cm×3.2 cm~7.2 cm×6.0 cm。根据创面位置和面积, 采用足底内侧动脉浅支穿支皮瓣或足底内侧动脉浅支皮穿支、足底内侧动脉深支内侧支联体皮瓣修复创面, 皮瓣切取面积为5.5 cm×3.5 cm~7.5 cm×6.8 cm。足部供区创面采用旋髂浅动脉穿支皮瓣修复。术后观察足底内侧动脉穿支皮瓣和旋髂浅动脉穿支皮瓣成活情况。皮瓣成活后指导患者行患手康复锻炼。术后定期门诊随访, 观察足底内侧动脉穿支皮瓣外形、色泽、质地及足部功能恢复情况。末次随访时, 测定足底内侧动脉穿支皮瓣两点辨别觉距离, 采用中华医学会手外科学会上肢部分功能评定试用标准及MHQ对患手功能进行评估。 结果 术后2例患者足底内侧动脉穿支皮瓣出现血管危象, 经急诊探查后皮瓣成活;其余患者足底内侧动脉穿支皮瓣和旋髂浅动脉穿支皮瓣均成活。术后随访6~18个月, 足底内侧动脉穿支皮瓣外观不臃肿, 色泽、质地与周围皮肤接近;足部跑、跳功能未受影响。末次随访时, 足底内侧动脉穿支皮瓣两点辨别觉距离为7~10 mm, 平均8 mm;患手功能评定为优者12例、良者3例;患手功能MHQ得分为81~95分, 患者对术后患手外观、疼痛情况、功能恢复情况均满意。 结论 应用足底内侧动脉穿支皮瓣整复手部掌侧瘢痕挛缩, 皮瓣切取简便、成活率高, 术后皮瓣感觉及患手功能恢复好, 足部供区损伤小, 值得临床推广。 Abstract:Objective To investigate the effects of medial plantar artery perforator flap in the reconstruction of palmar scar contracture. Methods This study was a retrospective observational study. From January 2016 to January 2023, 15 patients with palmar scar contracture who met the inclusion criteria were admitted to Guangzhou Peace Orthopedic Hospital, including 12 males and 3 females, aged 15 to 50 years. Before surgery, the Michigan Hand Outcomes Questionnaire (MHQ) scores for the affected hands ranged from 58 to 77, and the total active motion for the affected hands ranged from 190° to 220°. The skin and soft tissue defect area after scar excision on the palmar side of the affected hands was 5.2 cm×3.2 cm to 7.2 cm×6.0 cm. According to the location and area of the wounds, the defects were repaired using either medial plantar artery superficial perforator flaps or combined flaps of the cutaneous perforator of superficial branch of medial plantar artery and medial branch of medial plantar artery deep branch. The area of the harvested flaps was 5.5 cm×3.5 cm to 7.5 cm×6.8 cm. The donor site wounds on the feet were repaired using superficial circumflex iliac artery perforator flaps. Postoperatively, the survivals of the medial plantar artery perforator flaps and superficial circumflex iliac artery perforator flaps were observed. After survival of the flaps, patients were guided for rehabilitation exercises for the affected hands. Regular outpatient follow-up was conducted after surgery to observe the appearance, color, and texture of the medial plantar artery perforator flaps, and the recovery of foot function. At the final follow-up, the two-point discrimination distance of the medial plantar artery perforator flap was measured, the function of the affected hands was evaluated using the trial criteria for evaluation of partial function of upper extremity by the Hand Surgery Society of Chinese Medical Association and the MHQ. Results Postoperatively, two patients experienced vascular crisis of the medial plantar artery perforator flaps, while the flaps survived after emergency exploration; the medial plantar artery perforator flaps and superficial circumflex iliac artery perforator flaps survived in other patients. Follow-up for 6 to 18 months postoperatively showed that the medial plantar artery perforator flaps had no bulky appearance, similar color and texture to the surrounding skin, and the foot functions such as running and jumping were not affected. At the final follow-up, the two-point discrimination distance of the medial plantar artery perforator flap ranged from 7 to 10 mm, with an average of 8 mm; the affected hand function was rated as excellent in 12 cases and good in 3 cases; the MHQ scores of the affected hand function ranged from 81 to 95, and the patients were satisfied with the postoperative appearance, pain relief, and functional recovery of the affected hand. Conclusions The medial plantar artery perforator flap is used for the reconstruction of palmar scar contracture. The flap is easy to harvest, and has a high survival rate, resulting in good postoperative recovery of the flap sensation and function of the affected hand, and minimal donor site injury in the foot. It is therefore worthy of clinical promotion. -
