目的探讨小切口微创治疗(足母)外翻的有效方法. 方法 2002年8月～2004年6月,采用小切口微创手术和术后弹性外固定治疗(足母)外翻136例263足.其中男7例,女129例.年龄19～84岁.按Coughlin分型,轻度24例,中度63例,重度49例.263足均伴不同程度疼痛、足内弓塌陷和扁平足.经随访观察,对症状、体征及X线片测量结果进行疗效评定. 结果术后伤口均Ⅰ期愈合.本组获随访8～26个月,平均19个月.(足母)外翻畸形完全矫正, 足疼痛完全消失, 无骨不愈合及骨坏死征象,足内弓塌陷平均改善5°,跖趾关节功能及皮肤感觉基本正常;X线片示(足母)外翻角<12°、第1、2跖骨间角<9°及胫侧籽骨半脱位矫正<50% 105足,基本矫正158足.足疗效评定:优84例,良48例,中3例,差1例,优良率为97%. 结论小切口微创治疗(足母)外翻是一种损伤小、痛苦少、矫正彻底及不易复发的较理想治疗方法.

THE EFFECT OF MICRO-TRAUMA TECHNIC WITH SMALL INCISION ON TREATING HALLUX VALGUS

OBJECTIVE: To explore an effective micro-trauma technic with small incision for hallux valgus. METHODS: From August 2002 to June 2004, 136 cases (263 feet) with hallux valgus were treated with micro-trauma technic with small incision and postoperative external elastic fixation. Of all the cases, 7 were males and 129 were females. Their ages ranged from 19 to 84 years. According to Coughlin classification, there were 24 gentle cases, 63 medium cases, and 49 severe cases. All the feet were with some degree of pain and flatfoot. Symptom, sign and the results of X-ray were evaluated. RESULTS: Wound healed at stage I. All cases were followed up for 8 to 26 months, 19 months on average. Hallux valgus of the 263 feet were completely healed, feet pain disappeared, and no nonunion or osteonecrosis was observed. X-ray examination indicated that 105 feet's hallux valgus angle was less than 12 degrees, inter metatarsal angle less than 9 degrees, and remedy subluxation of the tibial sesamoid less than 50%. Evaluation on the result indicated that there were 84 cases of excellent result, 48 cases of good result, 3 cases of fair result, and 1 case of poor result. The rate of excellent and good was 97%. CONCLUSION: With less injury, less pain, complete restoration, and fewer possibility of relapse, micro-trauma technic with small incision is effective in treating hallux valgus.
