Summary
Thompson's prosthesis is effective for elderly patients with femoral neck fractures, whether cemented or uncemented. This study found no significant differences in outcomes, suggesting uncemented use is a viable option for hip fracture treatment.
Area of Science:
- Orthopedic Surgery
- Geriatric Medicine
- Biomaterials Engineering
Background:
- Intracapsular femoral neck fractures are common in the elderly.
- Thompson's prosthesis is a treatment option, with varying fixation methods.
- Optimal fixation method (cemented vs. uncemented) requires further investigation.
Purpose of the Study:
- To compare cemented versus uncemented Thompson's prosthesis for intracapsular femoral neck fractures.
- To evaluate patient outcomes including mobility, activity, walking aids, and pain.
- To assess radiological and clinical differences between fixation methods.
Main Methods:
- Retrospective study of 101 elderly patients (mean age 83.5 years) with femoral neck fractures.
- Patients treated with Thompson's prosthesis, either cemented (23%) or uncemented (77%).
- Comparison of pre- and postoperative mobility, activity, walking aids, thigh pain, and hip X-rays.
Main Results:
- No statistically significant differences were observed between cemented and uncemented groups in patient variables.
- Radiological loosening did not always correlate with symptomatic presentation.
- Intra- and postoperative complication rates were comparable to existing literature.
Conclusions:
- Thompson's prosthesis can be safely inserted uncemented for femoral neck fractures.
- Uncemented fixation offers a viable alternative with similar outcomes to cemented fixation.
- Modified osteotomy techniques can simplify future revisions.
