Key result
The type of fixation substantially affects postoperative stability of intertrochanteric fractures, highlighting the need for biomechanical studies to include physiologic loading.
Why the study?
Traditional classification systems for intertrochanteric fractures are of limited utility because they typically stratify fractures as stable or unstable based purely on fracture pattern without considering stability after fixation.
How does the type of fixation affect postoperative stability of intertrochanteric femur fractures?
How does the type of fixation affect postoperative stability of intertrochanteric femur fractures?
Traditional classification systems for intertrochanteric fractures are limited because they ignore post-fixation stability, which is substantially affected by the type of fixation used.
Traditional classifications may overlook post-fixation stability in intertrochanteric fractures; leaves open development of inclusive systems for clinical use.
SUMMARY: The stability of intertrochanteric fractures depends upon multiple factors including the fracture displacement, location and pattern, the type of fixation used for stabilization, and the loading that the fracture undergoes postfixation. Traditional classification systems are of limited utility because they typically stratify intertrochanteric fractures as stable or unstable based purely on the fracture pattern without consideration of the stability after fixation. Biomechanical studies evaluating the stability of various fixation constructs should include physiologic loading, including rotation around the axis of the femoral neck, and reproduce clinical failure modes to be clinically relevant. A growing body of evidence indicates that the type of fixation substantially affects postoperative stability of intertrochanteric fractures.
