| Background: Children's idiopathic or trauma-related coronal angular malformation around the knee might impair walking. If it doesn't improve, surgery like temporary hemiepiphysiodesis (TH) with an eight-plate implant is commonly used. Objective: To evaluate the efficacy, correction velocity, and complications of temporary hemiepiphysiodesis using eight plates for correction of coronal angular deformity around knee. Patients and methods: This work was a prospective study that had evaluated the use of eight plates for temporary hemi-epiphysiodesis with coronal angular deformity around the knee in 13 children (22 knees) who were operated upon at Menoufia University Hospitals and Helal Insurance Hospital between January 2022 and April 2023. Results: In valgus group Mechanical axis deviation (MAD) improved in 12 knees representing (92.3%) and only one knee (7.7%) hasn’t improved. mechanical lateral distal femoral angle (MLDFA) improved from 81.85±5.3 (range 72-89) pre operatively to 83.31±3.92 after 12 months. Medial proximal tibial angle (MMPTA) improved from 98.08±4.89 (range 92-109) pre operatively to 87.38±2.06 after 12 months. TFA improved from 13.15±0.8 (range 12-15) pre operatively to 6.77±2.01 after 12 months. The rate of improvement of MLDFA was 0.47±0.53, MMPTA was 0.96±0.45 and TFA was 0.59±2.1 per month. In varus group MAD improved in 8 knees representing (88.9%) and only one knee (11.1%) hasn’t improved. MLDFA improved from 96.67±5.39 (range 92-110) pre operatively to 90.89±7.22 after 12 months. MMPTA improved from 81.22±1.99 (range 87-84) pre operatively to 88±3.16 after 12 months. Mechanical tibiofemoral angle (TFA) improved from 12±1.66 (range 10-14) pre operatively to 6.89±2.03 after 12 months. The rate of improvement of MLDFA was 0.58±0.39, MMPTA was 0.66±0.3 and TFA is 0.5±0.3 per month. Conclusion: TH with eight plates is a successful surgery with a low incidence of complications and rebound for coronal angular deformity in patients with open physis. | ||
