Uncemented bipolar arthroplasty in extracapsular hip fracture in elderly patients.

INTRODUCTION

Extracapsular hip fractures in patients over 85 years old represent a therapeutic challenge due to their high vulnerability and risk of complications. This study analyzes the efficacy and safety of bipolar hip arthroplasty with uncemented femoral stems in this population.

MATERIALS AND

METHODS

A retrospective study was conducted at three referral hospitals, including 63 patients over 85 years old treated between 2019 and 2023. Clinical, radiological, and functional variables were evaluated with a minimum follow-up of 12 months. Hip function was assessed using the Harris Hip Score (HHS).

RESULTS

The mean age was 86.7 years, with a female predominance (63.5%). The average surgical time was 46±7minutes, and intraoperative blood loss was 220±40ml. The complication rate was low: 14.2% experienced mild hypotension, 1.6% suffered a periprosthetic fracture, and isolated cases of postoperative hyperglycemia and hypoalbuminemia were promptly resolved. The mean HHS was 79±8 points at 6 months and 81±6 points at 12 months. A total of 71.4% of patients regained their pre-injury ambulatory status. No significant prosthetic subsidence or femoral pain was observed.

CONCLUSION

Bipolar hip arthroplasty with uncemented femoral stems appears to be a safe and effective option for treating extracapsular hip fractures in patients over 85 years old, allowing early rehabilitation and reducing complications associated with cementation and osteosynthesis.
