Basal closing wedge osteotomy for correction of hallux valgus and metatarsus primus varus: 10- to 22-year follow-up

Between 1974 and 1985, 59 patients (83 feet) underwent basal closing wedge osteotomy in combination with a bunionectomy and a lateral soft tissue rele ase for correction of hallux valgus and metatarsus primus varus at this ins titution. Of the original 59 patients, 42 patients (60 feet) with at least 10 years of follow-up (average, 194 months; range, 144-266 months) were ava ilable for this study, Results were analyzed by review of the medical recor ds and plain radiographs, a standardized clinical questionnaire, and physic al examination. Of the 60 feet, patients rated outcomes as excellent or goo d in 51 feet (85%) and rated cosmesis as excellent or good in 44 feet (73%) , Radiographically at final follow-up, hallux valgus and intermetatarsal an gles averaged 19.9 degrees (range, 0-40 degrees) and 6.7 degrees (range, 0- 18 degrees), respectively, The sesamoid position was corrected from an aver age preoperative grade of 2.6 to a grade of 0.9 at final follow-up, The ave rage shortening of the first metatarsal was 5 mm, The disadvantages of the closing wedge osteotomy are that it is technically demanding and it entails the risk of shortening, dorsal malalignment, and metatarsalgia, In the cur rent study, long-term complications included hallux varus deformity (16 fee t), dorsal malalignment (15 feet), and metatarsalgia (14 feet). Despite goo d correction of the intermetatarsal angle and sesamoid position, the clinic al results and the incidence of complications after basal closing wedge ost eotomy were not as favorable as those reported for other procedures in the literature, Therefore, alternative procedures, such as the basal crescentic osteotomy or the basal chevron osteotomy, should be used.
