Fractures of the lateral hinge during open wedge high tibial osteotomy (HTO) are common. The TomoFix plate is effective for types I and III, with type II potentially needing bone grafts.
Area of Science:
- Orthopedic surgery
- Biomechanics
- Surgical complications
Context:
- Open wedge high tibial osteotomy (HTO) is a common procedure for knee osteoarthritis.
- Fracture of the lateral hinge is a known complication of HTO.
Purpose:
- To present the issue of lateral hinge fractures after HTO.
- To discuss prevention and treatment strategies for these fractures.
Summary:
- The Takeuchi classification (grades I-III) is suitable for lateral hinge fractures.
- TomoFix plates are effective for types I and III fractures.
- Type II fractures may require autologous bone grafting; short spacer plates are not recommended due to stability issues.
Impact:
- Improved understanding of lateral hinge fracture management.
- Guidance on implant selection for HTO.
- Potential reduction in HTO complications.

Fractures: Bone Repair
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the...
