Medial Wedge Opening High Tibial Osteotomy with an Extra Screw Fixation

Abstract

Medial wedge opening high tibial osteotomy (MWOHTO) is effective for managing a variety of knee conditions, varus malalignment of the knee, either secondary to osteoarthritis or residual adolescent tibia vara, are among the indications, fixation may be done using different methods (Stables, T-plate, Budu plate, and TomoFix). We are describing our technique of performing (MWOHTO) fixed with titanium T plate supplemented with an extra screw from the lateral side which we call “extra-focal” screw to obtain biplanar fixation which may add to the rotational stability at the osteotomy site.

Modified oblique high tibial osteotomy with minimal fixation for correction of adolescent tibia vara: A prospective case series study

“…5 All authors performing metaphyseal osteotomy for Blount`s correction concluded that the metaphyseal osteotomy used to correct a physeal deformity results in the need for lateral translation at the osteotomy site, thus particularly in larger deformities it will be difficult to hold the correction with a plate. [13][14][15] Asymmetrical physeal distraction with a monolateral fixator is also used for treatment of adolescent tibia vara. In all cases, the distraction had resulted in proximal tibial growth plate closure and carried risk of septic knee.…”
