Complications With Long Cemented Stems in Proximal Femoral Replacement

Area of Science:

• Orthopedic Surgery
• Biomedical Engineering
• Clinical Outcomes Research

Background:

• Cemented proximal femoral replacement is a common orthopedic procedure.
• The choice between long-stem and short-stem implants may influence patient outcomes.
• Understanding perioperative risks is crucial for patient safety.

Purpose of the Study:

• To compare short-term mortality rates between long-stem and short-stem cemented proximal femoral replacement.
• To evaluate intraoperative hemodynamic stability and resuscitation needs in both groups.
• To assess the risk of periprosthetic fracture with different stem lengths.

Main Methods:

• Retrospective review of 24 patients undergoing cemented proximal femoral replacement (13 long-stem, 11 short-stem).
• Comparison of intraoperative data including blood loss, transfusions, fluid resuscitation, hypotension, and oxygen desaturation.
• Assessment of mortality and need for revision surgery up to 1 year postoperatively.

Main Results:

• Significantly higher 1-year mortality in the long-stem group (77% vs. 27%, P=.03).
• Increased intraoperative blood transfusions, fluid resuscitation, hypotension, and oxygen desaturation in the long-stem group (P=.04).
• Two intraoperative deaths occurred in the long-stem group versus none in the short-stem group.

Conclusions:

• Long-stem cemented proximal femoral replacement is associated with increased intraoperative hemodynamic instability.
• Longer stems necessitate greater resuscitative efforts and carry a higher risk of mortality.
• Short-stem cemented proximal femoral replacement may offer a safer alternative regarding perioperative complications.
