Long-term clinical outcomes of scarf osteotomy in regional hospital Hong Kong

Background: Lack of local data concerning the long-term clinical outcomes of scarf osteotomy in Hong Kong. Methods: This is a retrospective review of 75 patients (88 feet) who underwent scarf osteotomy with a mean follow-up of 94.20 months (60–144 months). Clinical ratings were based on visual analo...

description Background: Lack of local data concerning the long-term clinical outcomes of scarf osteotomy in Hong Kong. Methods: This is a retrospective review of 75 patients (88 feet) who underwent scarf osteotomy with a mean follow-up of 94.20 months (60–144 months). Clinical ratings were based on visual analog scale (VAS) and American Orthopaedic Foot & Ankle Society (AOFAS) scale. Weight-bearing radiographs were used to perform angular measurements: (i) hallux valgus angle (HVA), (ii) intermetatarsal angle, (iii) distal metatarsal articular angle, and (iv) tibial sesamoid position before operation and at the time of latest follow-up. Results: The mean overall AOFAS scales improved from 29.66 (5–49) points preoperatively to 86.83 (39–100) points at the time of final follow-up. The VAS improved from 6.61 (5 to 9) to 0.66 (0 to 4). The average HVA correction was 25.42 (8–46). The 8- to10-year recurrence rate (HVA > 20) was 31.80%. A higher degree of preoperative HVA predicts higher recurrence rate. Conclusion: Scarf osteotomy is an effective procedure for symptom control and improvement in radiological parameters for hallux valgus deformity. However, recurrence rate is relatively high.
