Objective:
In this study, the efficiency of three different rigid screw types on preserving reduction in Lindgren-Turan osteotomy is investigated.
Material and Methods:
Between 2007-2012, 86 feet of 60 patients who underwent Lindgren-Turan osteotomy procedure due to hallux valgus deformity in our clinic were retrospectively evaluated. Fixation was done by Herbert screws, cannulated headless screws and 2.7 mm cortical screws. Hallux valgus angles, intermetatarsal angles and distal metatarsal articular angles were evaluated in preoperative, early postoperative and late postoperatively. Different rigid internal screws which are used in fixation after Lingdren-Turan osteotomy were evaluated by these angles.
Results:
While there was no statistically significant difference between averages of hallux valgus angles at early and late postoperative controls in cannulated headless group, the difference was significant in Herbert screw and 2.7 mm cortical screw groups. While there was no statistically significant difference between averages of intermetatarsal angles at early and late postoperative controls in cannulated headless and Herbert screw groups, the difference was significant in 2,7 mm cortical screw group. There was no statistically significiant difference between avareges of distal metatarsal articular angles at early and late postoperative controls in all screw groups.
Conclusion:
In fixation of osteotomy site by 2.7 mm cortical screws after Lindgren-Turan osteotomy, there was significant correction decrement at late postoperative intermetatarsal and hallux valgus angles. There was less reduction loss with cannulated headless screws in our study.
