Objective:

To quantify the incidence of specific mechanical complications (e.g., implant cut-out, cut-in) after CMN implantation and identify associated risk factors.

Key Findings:
  • 28 patients (7%) experienced mechanical complications.
  • Mechanical complications included implant cut-out, cut-in, and lateral protrusion.
  • Identified risk factors for complications included specific patient characteristics (e.g., age, comorbidities) and surgical technique (e.g., approach, implant type).
Interpretation:

The study highlights the importance of understanding mechanical complications in CMN fixation to improve surgical outcomes and patient care, suggesting that targeted interventions may enhance recovery.

Limitations:
  • Retrospective design may introduce bias.
  • Exclusion of high-energy trauma cases limits generalizability and may overlook complications in a broader patient population.
Conclusion:

Improving risk stratification and surgical decision-making can enhance patient outcomes following CMN implantation for hip fractures.
