IntraArticular Influence of PETS Technique Treating Limb Length Discrepancy for Both Femur and Tibia

Volcano deformity is an intra-articular deformity discovered after the wide use of the tension band plate (TBP) all over the world. Controversy on whether this is a pervasive effect that applies to all TBP treatments or just a sporadic event is still under debate. In contrast, percutaneous epiphysiodesis using transphyseal screws (PETS) has been under the radar for producing intra-articular influence. This study aimed to evaluate the potential for such central deformity.
