    The study evaluates medial cortical hinge fractures in lateral open wedge distal femoral osteotomy (LOW-DFO) to determine a safe hinge position.

  • 2

    LOW-DFO is effective for treating symptomatic valgus deformity, with good outcomes and a 90% survivorship at 5 years.

  • 3

    Common drawbacks of LOW-DFO include high reoperation rates and non-unions, often due to medial cortical hinge fractures.

  • 4

    The study included 100 patients who underwent LOW-DFO for various conditions, excluding those with prior deformities or malrotated radiographs.

  • 5

    A safe hinge position distal to the adductor tubercle is proposed to minimize the risk of hinge fractures in LOW-DFO.
