Summary
Primary hemiarthroplasty using cemented bipolar prosthesis effectively treated elderly patients with unstable intertrochanteric fractures, showing good mobility and few complications. This hip surgery offers a viable option for fracture management in older adults.
Area of Science:
- Orthopedic Surgery
- Geriatric Medicine
- Biomaterials Science
Background:
- Unstable intertrochanteric fractures pose significant challenges in elderly patients.
- Primary hemiarthroplasty is a surgical option for managing these fractures.
Purpose of the Study:
- To evaluate the efficacy and outcomes of primary hemiarthroplasty with cemented bipolar prosthesis in elderly patients with unstable intertrochanteric fractures.
Main Methods:
- A cohort of 54 elderly patients (mean age 75.6 years) with unstable intertrochanteric fractures underwent primary hemiarthroplasty using a cemented bipolar prosthesis between 1997 and 2001.
- Patient outcomes were assessed over a mean follow-up period of 22.3 months.
Main Results:
- Thirty-three patients regained ambulation with a walker within the first post-operative week.
- Complications included one deep infection, one case of acetabular erosion, four instances of non-union of the greater trochanter, and five cases of leg-length discrepancy.
- No dislocations or aseptic loosening were reported.
- The Harris hip-scoring system indicated 17 excellent and 14 good results at 12 months.
- A decrease in the inner motion of the bipolar head was observed over time.
Conclusions:
- Primary hemiarthroplasty with cemented bipolar prosthesis is a safe and effective treatment for unstable intertrochanteric fractures in the elderly.
- The procedure facilitates early mobilization and achieves satisfactory functional outcomes.
- Potential complications such as infection, loosening, and wear should be monitored, although they were infrequent in this cohort.
