迷你双螺纹空心钉结合截骨治疗拇外翻

Mini double-thread hollow screw combined with osteotomy for the treatment of hallux valgus

背景:拇外翻畸形矫正方式多样,采用迷你双螺纹空心钉材料结合截骨矫形的方式损伤小,能够满足拇外翻矫形的目的,是临床上新型的微创生物型内固定材料。目的:回顾性分析迷你双螺纹空心钉材料应用于截骨矫形拇外翻治疗中的临床疗效。方法:选择拇外翻畸形患者30例,其中双侧矫形患者8例,单侧矫形患者22例。根据自愿均采用第一跖骨截骨矫形迷你双螺纹空心钉内固定,治疗前后拍摄X射线片测量外翻角、跖间角、籽骨位置,进行AOFAS评分,并计算第一跖骨短缩长度。结果与结论:采用迷你双螺纹空心钉结合截骨矫形治疗后,拇外翻畸形患者的外翻角、跖间角、AOFAS评分及籽骨位置较治疗前明显改善,第一跖骨短缩在矫形可控范围内避免畸形复发及跖骨痛。

BACKGROUND： Treatments for hallux valgus are diverse. Mini double thread hollow screw combined with osteotomy surgery is a small invasive surgery, which can meet the orthopedic purpose of hallux valgus and can be considered as the new minimally invasive biological fixation material in clinic. OBJECTIVE： To retrospectively analyze the curative effect of mini double-thread hollow screw combined with osteotomy for the treatment of hallux valgus. METHODS： Thirty patients with hallux valgus （eight patients with bilateral orthopedic operation and 22 patients with unilateral orthopedic operation） were selected and treated with the first metatarsal osteotomy combined with mini double-thread hollow screw internal fixation according to the willingness of the patients The X-ray films were taken before and after operation to compare the hallux valgus angle, intermetatarsal angle, sesamoides position and the American Orthopedic Foot and Ankle Society Ankle Hindfoot Scale score. And the shortening length of first metatarsal bone was calculated.RESULTS AND CONCLUSION： Hallux valgus angle, intermetatarsal angle, sesamoides position and American Orthopaedic Foot and Ankle Society Ankle Hindfoot Scale score post-operation were improved obviously compared with those pre-operation. The shortening length of the first metatarsal bone was in orthopedic controllable scope, thereby avoiding deformity recurrence and metatarsus pain.
