Proximal metatarsal osteotomy: relation between 1- to greater than 3-years results.

UNLABELLED: We analyzed the relationship between the 1-year and greater than 3-years results of a distal soft tissue procedure with a proximal osteotomy for hallux valgus in the same patient population. The series consisted of 55 feet treated with this procedure. The results at 1 year and greater than 3 years were evaluated. The final followup was greater than 3 years. Patients with pain in the first metatarsophalangeal joint at the 1-year followup had a greater risk of having pain at the final followup than did patients without pain at the 1-year followup. Patients with metatarsalgia at the 1-year followup had a greater risk of having metatarsalgia at the final followup than did patients without metatarsalgia at the 1-year followup. The extension of the first metatarsophalangeal joint at the final followup was greater than extension at the 1-year followup. In 48 feet (87%), radiologic evaluation showed no or minimal changes in the hallux valgus and intermetatarsal angles between 1 year and greater than 3 years followup. The data suggest the 1-year results predict those beyond 3 years, although the extension of the first metatarsophalangeal joint may increase 1 year after surgery.
