Abstract

Abstract:

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.
