Retrospective analysis reveals distinct characteristics of hinge fractures in patients undergoing distal femoral osteotomy, indicating significant implications for recovery.
Key Points
Intraoperative hinge fractures show longer healing times than non-fractured cases, averaging 3.9 months compared to 2.7 months for postoperative fractures.
Significant correlations exist between hinge fractures and both mechanical axis deviation and lateral distal femur angle corrections.
The incidence of postoperative hinge fractures is higher when hinges are located proximal to the adductor tubercle in genu valgum patients.
Body weight is a significant factor, as higher body weights correlate with increased rates of both intraoperative and postoperative hinge fractures.
