    Abstract:
    BACKGROUND: Opening wedge proximal metatarsal osteotomy combined with first metatarsophalangeal arthroplasty can be used to correct first metatarsus primus varus with a high intermetatarsal angle and a short first metatarsal. METHODS: 147 feet in 138 patients with degenerative first metatarsophalangeal arthrosis, >or=15 degrees of metatarsus primus varus and, a short first metatarsal were included. Preoperative and postoperative clinical, radiographic, and subjective outcome measurements were taken (Scale AOFAS). RESULTS: The mean first intermetatarsal angle decrease was 7.79+/-1.43 degrees and the mean increase in first metatarsal length was 2.88+/-0.45 mm. The pre-intervention mean values were 52.6 points in the AOFAS scale, and an overall result of 92.95 obtained after surgery (P<0.001). CONCLUSIONS: The opening proximal first metatarsal osteotomy without internal fixation and with first metatarsophalangeal resection arthroplasty can correct severe hallux valgus with an intermetatarsal angle >or=15 degrees and a short first metatarsal, achieving low rate of complications.
