Medial patellar luxation (MPL) has recently been associated with distal femoral varus (DFV), in mid-size dogs. The most common correction of DFV involves a distal femoral lateral closing wedge ostectomy stabilized with a laterally applied bone plate. Given this surgical approach complexity, we devised an alternative technique to DFV correction. A medial opening wedge osteotomy, often considered technically easier than closing wedge ostectomies is stabilized using an angle stable interlocking nail, which, unlike plates, is shielded against deleterious bending forces, cannot fail via implant pullout and provides intrinsic fragment stability during osteosynthesis. Surgical technique and clinical outcomes will be described in this presentation.
