Abstract

Objectives: To report the incidence of overcorrection as complication following eight-plate application for genu varum/valgum deformities and its management.
Methods: This was a retrospective review of children who underwent growth modulation for genu varum/valgum between 2012-2019. Data of patients who had presented with overcorrection of their primary deformity, the reasons for such complication and its management were collected and analysed.
Results: 110 children had undergone growth modulation during the study period. 75 children (68%) had achieved deformity correction in mean time of 14.4 months and had their implant removed on time when intercondylar (ICD)/intermalleolar (IMD) distance was ≤ 5 centimeters (cms) and/or Hip Knee Ankle (HKA) angle was < ±6⁰. 29 children (26%) were lost to follow up. 6 children (5.4%) had presented with overcorrection of moderate to severe grade with mean ICD/IMD of 13.3 cms (range 11-18) and mean HKA angle of 14.3⁰ (range 11-21⁰). Mean age of initial surgery was 6.1 years (range 5-8). Mean time gap of presentation with overcorrection was 33.6 months (range 24-45). Lack of awareness, long distance of hospital, medical expenses were some of the notable reasons for irregular follow-up. All 6 had an open physes with growth remaining when they presented with overcorrection. These children managed with repeat growth modulation. Final correction was achieved at mean time of 15.3 months and underwent implant removal. At the latest follow up of 4.4 years, limb alignment within physiologic limits was maintained.
Conclusion: Children undergoing growth modulation should be carefully monitored with regular follow-up to avoid complication of overcorrection. Overcorrection beyond physiologic limits can be managed with repeat growth modulation in younger children with open physes.
