A hinge position distal to the adductor tubercle minimizes the risk of hinge fractures in lateral open wedge distal femoral osteotomy
To evaluate the incidence and morphology of medial cortical hinge fractures in lateral open wedge distal femoral osteotomy (LOW-DFO) and to determine a safe zone for the osteotomy hinge position, which is crucial for minimizing complications.
Key Findings:
Medial cortical hinge fractures were identified as a common complication in LOW-DFO.
The position of the osteotomy hinge significantly affects the risk of hinge fractures due to biomechanical factors.
A distal hinge position relative to the adductor tubercle minimizes the risk of fractures.
Interpretation:
The findings suggest that careful planning of the osteotomy hinge position can reduce the incidence of medial cortical hinge fractures, potentially improving surgical outcomes and patient safety.
Limitations:
Retrospective design may introduce selection bias.
Limited to a single institution, which may affect generalizability.
Exclusion of patients with certain conditions may limit the applicability of findings.
Potential biases in radiographic assessments could affect the identification of hinge fractures.
Conclusion:
Positioning the osteotomy hinge distal to the adductor tubercle is recommended to minimize the risk of hinge fractures in LOW-DFO.
Patients with preoperative vitamin D deficiency had higher postoperative pain scores and opioid use after mastectomy, including more than triple the odds of moderate to severe pain within 24 hours of surgery.
