The main purpose of our study was to investigate the efficacy of dual two-hole tension band plates in the treatment of lower extremity limb length discrepancy (LLD). We retrospectively reviewed patients who underwent epiphysiodesis utilizing dual two-hole tension band plates due to lower extremity LLD between January 2012 and June 2018. The efficacy of epiphysiodesis was defined as the inhibited percentage of the expected growth of the physis between two time intervals and was calculated between 0-6 months and 6-18 months as the primary outcome. The relationship of efficacy of epiphysiodesis with time intervals, bone segments, physeal coverage percentage by the screws, age and interscrew angle and physeal health was also assessed. A total of 11 patients' 17 bone segments (9 femurs and 8 tibias) with a mean age of 8.7 +/- 2.3 were included. The mean efficacy of the epiphysiodesis in the first 6 months for femurs was 23 +/- 20 % (range, 0-53%) and for tibias was 21 +/- 19 % (range, 0-53%); between 6 and 18 months it was 27 +/- 19 % (range, 0-56%) for femurs and 15 +/- 19 % (range, 0-50%) for tibias. In the first 6 months, physeal coverage percentage by the screws (r = 0.503, P = 0.04) and age (r = -0.534, P = 0.027) had a strong correlation with the epiphysiodesis efficacy. Dual two-hole tension band plating has variable efficacy in the treatment of LLD. Age and physeal coverage percentage by the screws could be related to epiphysiodesis efficacy.
