The aim of this study is to present the clinical results obtained by metatarsal osteotomy (Wilson osteotomy) for the correction of hallux valgus deformity. Tools and Methods: In our clinic, 48 patients (36 women, 12 men, an average age, 41±13.6 years) with Wilson osteotomy for the correction of light hallux valgus deformity between 2001 and 2010 were evaluated as retrospective. To evaluate the clinical outcome of osteotomy, hallux valgus angle (HVA), intermetatarsal angle (IMA), American Orthopedic Foot and Bracelet Association (AOFAS) score, sesamoid position, first metatarsofalanjeal joint movement range and visual analog score (VAS) for pain were used. Results: Patients were monitored for 28.5±10.6 months after surgery. HVA, which was preoperative 26.6°±6.8°, fell to 7.3°±0.1° three weeks after surgery (p<0.001). Similarly, IMA showed a significant decline after osteotomy (12.7°±2.2° to 6.4°±2.4°, p<0.001). The decline recorded in HVA and IMA continued in the final assessment. After osteotomy, the AOFAS score increased from 56±13 to 87±12 (p<0.001). Sesamoid position has reached normal limits (3.0±1.7 to 1.1±0.5 p=0.008). The first metatarsofalanjeal joint movement range increased in dorsiflexion (40°±9.0° to 50°±12.0°, p<0.001) and decreased in plantar flexion (35.0°±11.0° to 45°±9.0°, p<0.001). The preoperative VAS pain score of 5.7±3.1 fell to 1.35±0.8 after osteotomy. The result: Wilson osteotomy is radiologically and clinically effective in the correction of light hallucus valgus deformity and should be preferred by surgical technique.

Material and Methods: The clinical data of 48 feet of 48 patients (36 females, 12 males; average age, 41±13.6 years) who underwent Wilson's osteotomy for correction of mild hallux valgus deformity between 2001 and 2010 in our clinic were retrospectively reviewed. The clinical outcome of the osteotomy was evaluated by hallux valgus angle (HVA), intermetatarsal angle (IMA), the American Orthopaedic Foot and Ankle Society (AOFAS) score, sesamoid position, range of first metatarsophalangeal joint motion, and visual analogue scale (VAS) score. Results: Patients were followed for 28.5±10.6 months after the surgery. HVA decreased significantly from preoperative 26.6°±6.8° to 7.3°±0.1° at three weeks after the operation (p<0.001). IMA also showed significant decrease with osteotomy (from 12.7°±2.2° to 6.4°±2.4°, p<0.001). The decrease in both HVA and IMA was persistent to the last evaluation. AOFAS score significantly improved from 56±13 to 87±17 with osteotomy (p<0.001). Sesamoid position becomes within normal limits after the operation (from 3.0±6. 7 to 1.1±0.5, p = 0.008. Range of motion of the first metatarsophalangeal joint increased at dorsiflexion (from 38.0°±9.0° to 47.0°±12.0°, p<0.001) and decreased at plantar flexion (from 35.0°±11.0° to 29.0°±9.0°, p<0.001). VAS pain score decreased significantly from preoperative 7.72±3.1 points to 1.35±0.8 points at the last evaluation. Conclusion: Wilson's osteotomy provides effective correction of mild hallux valgus deformity both radiologically and clinically, thus should be considered as an optimal surgical technique.
