Overview
Lateral hinge fracture (LHF) is a recognized complication following opening wedge high tibial osteotomy (OWHTO) 1. This fracture can arise from various factors related to the osteotomy technique and fixation 1.Diagnosis
Lateral hinge fracture (LHF) is a complication of opening wedge high tibial osteotomy 1.
Factors contributing to LHF include osteotomy level, degree of opening, hinge position, and type of fixation plate 1.Management
Long locking plates offer superior biomechanical stability for LHF compared to short plates 1.
Long locking plates should be utilized in cases of LHF after OWHTO 1.Key Recommendations
Long locking plates should be used for lateral hinge fractures after opening wedge high tibial osteotomy due to their superior biomechanical stability 1. (Evidence: Moderate)
Consider the osteotomy level, amount of opening, hinge position, and type of plate when managing lateral hinge fractures after opening wedge high tibial osteotomy 1. (Evidence: Expert opinion)References
