title: Transosseous capsuloplasty improves the outcomes of Lindgren-Turan distal metatarsal osteotomy in moderate to severe hallux valgus deformity.
abstract: BACKGROUND
  Lindgren-Turan osteotomy used in hallux valgus deformity is a subcapital, transverse displacement osteotomy of the first metatarsal without any additional capsular repair. The aims of this study are to describe a transosseous capsuloplasty technique in this procedure and evaluate whether capsuloplasty would improve the clinical and radiological outcomes in patients with moderate to severe hallux valgus deformity.
  
  
  METHODS
  Twenty-three feet operated by Lindgren-Turan osteotomy (Group B) and 25 feet operated by the same osteotomy combined with transosseous capsuloplasty (Group A) were evaluated retrospectively for the correction of the hallux valgus, intermetatarsal and distal metatarsal articular angles, sesamoid reduction, American Orthopaedic Foot and Ankle Society (AOFAS) Clinical Rating Scale as well as patient satisfaction. The mean postoperative follow-up was 14 (range 12-28) months.
  
  
  RESULTS
  All radiological parameters improved considerably as a result of both groups. However, postoperative improvements in intermetatarsal and distal metatarsal articular angles were greater in Group A. Complete reduction of medial sesamoid was achieved in 52% of patients in Group A, whereas 17.4% of patients in Group B had complete reduction. AOFAS scores and number of patients with complete satisfaction in Group A were significantly greater than that in Group B.
  
  
  CONCLUSIONS
  Better clinical and radiological outcomes can be achieved in patients with moderate to severe hallux valgus deformity operated by Lindgren-Turan distal metatarsal osteotomy, when it combines with transosseous capsuloplasty.
