Short-term Outcomes of High Tibial Osteotomy Using a Plate Versus a Plate With an Interbody Fusion Cage in Adolescent Tibia Vara : a Comparative Study

Condition(s) studied

Investigational drug(s) / intervention(s)

high tibial osteotomy using interbody fusion cage: correction of adolescent tibia vara with high tibial osteotomy using interbody fusion cage

Study summary

Tibia vara is a progressive angular deformity of the lower limb centered at the proximal tibial physis, producing a characteristic bowing of the leg. The condition is believed to result from an abnormal distribution of biomechanical stresses combined with an underlying genetic predisposition. (1) Excessive mechanical loading on the medial portion of the proximal tibial growth plate leads to asymmetric physeal activity, ultimately causing a pathologic varus deformity of the tibia.(²)

Eligibility

Primary outcome measure(s)

• correction of tibia vara radiologically — 6 months
  Change in MPTA from baseline to 6 months, measured on radiographs by two blinded observers.
• correction of tibia vara on radiographs — 6 months
  Change in MPTA from baseline to 6 months, measured on radiographs by two blinded observers.
