Abstract

ABSTRACT
Background:
The rationale behind temporary hemiepiphysiodesis is to tether growth on the convex side of the deformity to allow the concave side of the physis to continue growth leading to deformity correction. Tension band plating in the form of 8-plate had been introduced by Stevens in 2007 to allow for guided growth correction. It is an easy, minimal invasive procedure that allows for early weight bearing

Patients and Methods:
This study included 38 patients. Deformity was bilateral in 24 patients (a total of 62 knees). 25 females (65.8%) and 13 males (34.2%). The cause of deformity was idiopathic in 29 patients (76.3%), post-traumatic in 5 patients (13%) and chronic renal failure in 4 patients (10.7%). Mechanical axis deviation MAD, lateral distal femoral angle LDFA and medial proximal tibial angle MPTA were recorded for all patients at presentation and on follow up for monitoring of deformity correction.
Results:
Mechanical axis deviation MAD corrected from (Mean ± SD) 34.3 ± 14.3mm to 7.9 ± 5.3 mm. Lateral distal femoral angle LDFA corrected from (Mean ± SD) 77.9 ± 3.18 °to 90.5 ± 2.55 degrees. This was found to be statistically significant. P value
