It is used in the treatment for several conditions, including skeletal class II malocclusion, cleft lip and cleft palate, vertical maxillary excess (VME) or deficiency, and some specific types of facial trauma, particularly those affecting the mid-face.
High tibial osteotomy is an orthopaedic surgical procedure which aims to correct a varus deformation with compartmental osteoarthritis.Since the inception of the procedure, advancements to technique, fixation devices, and a better understanding of patient selection has allowed HTO to become more popular in younger, more active patients hoping to combat arthritis.
