Comparison of modified Lindgren-Turan operation and proximal crescentic osteotomy combined with distal soft tissue procedure in the treatment of hallux valgus

Abstract

Objectives: We compared the results of moderate hallux valgus deformities managed with modified Lindgren-Turan (MLT) osteotomy and proximal crescentic osteotomy combined with distal soft tissue procedure (PCO-DP).
Patients and methods: Twenty-three feet of 18 patients (3 men and 15 women) with moderate hallux valgus deformity were treated between 2003 and 2006. Fourteen feet of 10 patients were treated by MLT and 9 feet of 8 patients were treated by PCO-DP. Radiographic evaluation included measurements of hallux valgus angle (HVA), intermetatarsal angle (IMA), distal metatarsal articular angle (DMAA), medial sesamoid position, metatarsophalangial arthrosis, shortening of the first metatarsal and metatarsophalangial subluxation. AOFAS score was used in the clinical examination. The mean follow-up period was 27.3 months (range 9 to 43 months) for MLT group and 25.2 months (range 6- 40 months) for PCO-DP.
Results: Preoperative and postoperative mean AOFAS scores of modified Lindgren-Turan group were 41.5 and 87.8, respectively (p<0.001). Preoperative and postoperative mean AOFAS scores of PCO-DP were 51.9 and 91.1, respectively (p <0.001).
Conclusion: Radiological and functional results of modified Lindgren- Turan osteotomy and proximal crescentic osteotomy combined with distal soft tissue procedure in the treatment of moderate hallux valgus deformity revelead similiar results. Thus, we suggest that modified Lindgeren-Turan osteotomy may be a preference by the reason of easier surgical technique with a single incision.
