Q. The following image shows a small plate implant (held with a K wire ) for treatment of knee deformity in an adolescent male on medial side of the knee. Select the appropriate diagnosis of the patient's deformity?
1. genu valgum
2. ganu varum
3. genu recurvatum
4. congenital dislocation of knee
Answer - 1
The plate, in the shape of letter '8' is also called 'Eight plate' and better known as ' Tension band plate' . It is used for Hemi-epiphysiodesis (unilateral fusion of growth plate) and growth modulation. The other implants used for this purpose in older times were 'bone staples'.
The plate acts as reversible epiphysiodesis implant as the removal of it may resume the growth if desired.
Usually the angular deformities of lower limbs are managed - medial side plating in genu valgum and lateral side plating for genu varum. ( pnemonic lateRal - genu vaRum)
It is intended to stop growth of attached side of limb , thus unopposed side growth corrects or neutralises the deformity.
In this manner it can also be used for retroversion , as posterior plating.
