Does femoral stem choice associate with survivorship and clinical outcomes after conversion total hip arthroplasty? A retrospective analysis and novel treatment algorithm
To evaluate the impact of femoral stem type selection on outcomes, including survivorship and patient-reported outcome measures (PROMs), following conversion total hip arthroplasty (cTHA) after proximal femoral fracture fixation.
Key Findings:
51 patients were included, with a mean age of 73 years and a mean BMI of 27.5.
Types of stems used included 62.7% diaphyseal-engaging, 19.6% metaphyseal-engaging, and 17.6% cemented stems.
Cemented stems were more commonly used in older patients, with statistical significance (p-value needed).
Radiographic signs of osteoarthritis were present in 90% of cases prior to cTHA.
Interpretation:
The study highlights the need for further investigation into the impact of femoral stem type on outcomes in cTHA, as current literature is limited, particularly regarding clinical implications.
Limitations:
Retrospective design may introduce selection bias, potentially affecting the reliability of findings.
Limited sample size may affect the generalizability of findings to broader populations.
Lack of long-term follow-up data on survivorship and functional outcomes limits the ability to draw definitive conclusions.
Conclusion:
The findings suggest that femoral stem selection may influence outcomes in cTHA, warranting further research to establish guidelines for stem choice based on fracture patterns and fixation methods, particularly in light of existing literature.

Systematic review found robotic-assisted total hip arthroplasty improved implant positioning precision without demonstrating better patient-reported outcomes or lower complication rates than conventional surgery.
