Short-term efficacy of minimally invasive multi-planar soft tissue lysis in treatment of congenital clubfoot

Abstract:

Objective：To investigate the short-term efficacy of minimally invasive multi-planar soft tissue lysis in the treatment of congenital clubfoot. Methods：A retrospective analysis was performed on 32 patients（45 feet） with congenital clubfoot who underwent minimally invasive multi-planar soft tissue lysis in our hospital from July 2014 to June 2017. The Dimeglio scores and the degrees of six angles on X-ray before treatment and at the last follow-up were collected. The efficacy was evaluated and the correlations between Dimeglio score and degrees of six angles were analyzed. Results：All patients were followed up for （12.6±4.8） months（ranged from 6.2 to 24.9 months）. The median Dimeglio score at the last follow-up was 2.0（1，3），which was significantly better than that before treatment（P=0.000）. There were significant changes in the degrees of six angles on X-ray after treatment（P<0.05）. Only the degree of the anteroposterior talus-first metatarsal angle was positively correlated with Dimeglio score（r=0.346，P=0.020）. Conclusion：Minimally invasive multi-planar soft tissue lysis has good short-term efficacy because of its minimal invasion，unobvious postoperative scar，and good outcomes in ankle joint function and flexibility in the treatment of congenital clubfoot
