Abstract

PURPOSE
The purpose of this study was to retrospectively analyze the clinical and radiologic results of the proximal crescentic osteotomy for moderate to severe hallux valgus deformity.
MATERIALS AND METHODS
Between March 2001 and March 2008, 55 patients (71 feet) who had undergone crescentic osteotomy and distal soft tissue procedure for hallux valgus were followed up for more than one year. The average follow-up period was 15.8 months (12~28 months) and the average age at the time of surgery was 49.8 years (20~69 years). We analyzed the hallux valgus angle (HVA), the first-second intermetatarsal angle (IMA), the length of 1st metatarsal bone and the position of medial sesamoid in preoperative and the last follow-up radiographs. The American Othopeaedic Foot and Ankle Society (AOFAS) score and patient satisfaction were measured by modifying Johnson's method which were used for clinical outcome assessments.
RESULTS
The HVA and the IMA were 36.2 and 15.8 degrees preoperatively, and 10.8 and 3.9 degrees at the last follow-up, respectively. The amount of shortening of 1st metatarsal bone averaged 2.3+/-1.1 mm postoperatively. The medial sesamoid position improved from a preoperative average of grade 6.6 to the last follow-up average of grade 1.9. The AOFAS score improved from a preoperative average of 45.3 points to an average 90.6 points at the last follow-up. The patient's satisfaction was completely satisfied in 61 cases (85.9%), satisfied with minor reservations in 6 cases (8.5%), satisfied with major reservations in 2 cases (2.8%), and dissatisfied in 2 cases (2.8%).
CONCLUSION
Proximal crescentic osteotomy produced satisfactory results for moderate to severe hallux valgus deformity.
