  • Effectiveness of double metatarsal osteotomy for severe hallux valgus with increased distal metatarsal articular angle

    ObjectiveTo summarize the technique and effectiveness of double metatarsal osteotomy for treating severe hallux valgus with increased distal metatarsal articular angle (DMAA).MethodsBetween June 2014 and December 2017, 64 patients (94 feet) of severe hallux valgus with an increased DMAA were treated with the double metatarsal osteotomy (distal metatarsal Reverdin osteotomy+proximal metatarsal open wedge osteotomy) combined with Akin osteotomy and soft tissue surgery to correct the deformity. There were 10 males (15 feet) and 54 females (79 feet) with an average age of 44.5 years (range, 26-66 years), including 34 of unilateral foot and 30 of bilateral feet. The Maryland metatarsophalangeal joint score of the American Orthopaedic Foot and Ankle Society (AOFAS) was 54.3±7.4 and the visual analogue scale (VAS) score was 6.0±2.0. The pre- and post-operative AOFAS score, VAS score, DMAA, hallux valgus angle (HVA), first-second intermetatarsal angle (1-2IMA), and the first metatarsal length (FML) were recorded and compared.ResultsAll incisions healed by first intention. All patients were followed up 12-15 months, with an average of 13.2 months. The complications occurred in 4 feet, including 1 foot of hallux stiffness, 1 foot of numbness at the edge of the wound, 1 foot of metastatic metatarsalgia, and 1 foot of metatarsal bone necrosis. At 1 year after operation, the Maryland metatarsal joint score of AOFAS was 89.2±7.4, showing significant difference compared with preoperative score (t=18.427, P=0.000); and the effectiveness was rated as excellent in 78 feet, good in 12 feet, poor in 3 feet, and bad in 1 foot, with an excellent and good rate of 95.7%. The VAS score was 1.5±2.0, showing significant difference compared with the preoperative score (t=10.238, P=0.000). The X-ray films showed that the osteotomies achieved bony healing at 3 months after operation. There were significant differences (P<0.05) in HVA, 1-2IMA, and DMAA between preoperation and 6 months and 1 year after operation; but no significant difference was found in FML between preoperation and 1 year after operation (t=0.136, P=0.863).ConclusionFor the patients with severe hallux valgus with increased DMAA, the double metatarsal osteotomy can significantly relieve the clinical symptoms and improve the imaging parameters with less postoperative complications.
