Abstract:
Objective: To evaluate the short-term effectiveness of the first ray tri-plane osteotomy and other metatarsal basal osteotomy in treatment of hallux valgus with moderate and severe metatarsus adductus. Methods: Between February 2012 and September 2016, 10 patients (12 feet) of hallux valgus with moderate and severe metatarsus adductus were admitted and treated with the first ray tri-plane osteotomy and other metatarsal basal osteotomy and lateral soft tissue release. There were 1 male (2 feet) and 9 females (10 feet) with an average age of 34.5 years (range, 21-55 years). The disease duration ranged from 3 to 10 years (mean, 5.8 years). The degree of metatarsal adductus was moderate in 4 feet and severe in 8 feet according to modified Sgarlato measurement method. Preoperative American Orthopaedic Foot and Ankle Society (AOFAS) score was 46.4±9.3. The metatarsus adductus angle (MAA) was (25.41±3.66)°, hallux valgus angle (HVA) was (41.42±9.67)°, and the first-second intermetatarsal angle (1-2IMA) was (10.72±2.26)°. Results: All incisions healed by first intention. All patients were followed up 18-24 months, with an average of 21.4 months. One patient (1 foot) had metastatic metatarsalgia after operation, but the symptoms disappeared after symptomatic treatment. X-ray re-examination showed that all osteotomies healed, and the healing time was 2.4-3.2 months, with an average of 2.8 months. At last follow-up, MAA was (8.42±0.71)°, HVA was (13.29±1.03)°, 1-2IMA was (4.41±0.48)°, and AOFAS score was 89.8±5.9. There were significant differences in clinical and radiographic indexes between pre- and post-operation ( P<0.05). Conclusion: The first ray tri-plane osteotomy combined with other metatarsal basal osteotomy has a significant short-term effectiveness in the treatment of hallux valgus with moderate and severe metatarsus adductus.
