Results of the Ludloff Osteotomy for Moderate to Severe Hallux Valgus Deformity / 대한족부족관절학회지

ABSTRACT

PURPOSE: To evaluate the clinical and radiologic results of the Ludloff osteotomy for moderate to severe hallux valgus deformity retrospectively. MATERIALS AND METHODS: Between January 2003 and October 2006, 33 patients (42 feet) who had undergone with Ludloff osteotomy combined with distal soft tissue procedure were followed up for more than one year. The average follow-up period was 14.6 months and the average age at the time of surgery was 47.7 years (26-70 years). The American Othopeaedic Foot and Ankle Society (AOFAS) score was used for clinical outcome assessments. We analyzed the hallux valgus angle (HVA), the first-second intermetatarsal angle (IMA) and the degrees of the tibial sesamoid subluxation in preoperative and the last follow-up radiographs. RESULTS: The AOFAS score improved from a preoperative average of 45.6 points to an average 84.3 points at the last follow-up. HVA and IMA were 34.8 and 14.5 degrees preoperatively, 17.2 and 5.9 degrees at the last follow-up. The tibial sesamoid position improved from a preoperative average of grade 2.5 to the last follow-up average of grade 1.2. CONCLUSION: Ludloff osteotomy produced satisfactory results for moderate to severe hallux valgus deformity.
