Summary
Heterotopic ossification (HO) occurred more frequently in cemented Bateman bipolar hemiarthroplasty for femoral neck fractures compared to uncemented procedures. Incidence was not linked to patient age or sex.
Area of Science:
- Orthopedic surgery
- Biomedical engineering
Background:
- Retrospective analysis of heterotopic ossification (HO) incidence.
- Focus on Bateman bipolar hemiarthroplasty for femoral neck fractures.
Purpose of the Study:
- Evaluate HO incidence in cemented vs. uncemented femoral neck fracture treatment.
- Compare outcomes of Bateman bipolar hemiarthroplasty.
Main Methods:
- Retrospective study of 451 patients (October 1985 - July 1990).
- Bateman bipolar hemiarthroplasty: 261 uncemented, 190 cemented.
- Average follow-up of 46 months.
Main Results:
- Higher HO incidence in the cemented group (p = 0.014).
- Cemented procedures had longer surgical time (+20 min) and greater blood loss (+160 ml).
Conclusions:
- Cemented Bateman bipolar hemiarthroplasty is associated with increased HO formation.
- HO incidence is independent of patient age and sex.
