Summary
The BiCONTACT femoral stem offers excellent long-term survival for both cemented and uncemented hip replacement surgeries. This modular system ensures bone preservation and high implant success rates over 11 years.
Area of Science:
- Orthopedic Surgery
- Biomaterials Engineering
Background:
- The BiCONTACT femoral stem is a modular hip implant system.
- It is designed for both cemented and uncemented fixation methods.
- Standardized instrumentation aims to preserve bone stock.
Purpose of the Study:
- To evaluate the long-term clinical outcomes of the BiCONTACT femoral stem.
- To compare the survival rates of cemented versus uncemented implantation.
- To assess the efficacy of a modular hip stem system.
Main Methods:
- Prospective follow-up studies of 250 cemented (Series B) and 250 uncemented (Series A) BiCONTACT femoral stem implantations.
- Analysis of long-term survival rates and follow-up rates.
- Standardized surgical procedures were used for both fixation types.
Main Results:
- After 11 years, the uncemented group (Series A) showed a survival rate of 97.1% (follow-up 99.2%).
- The cemented group (Series B) demonstrated an 11-year survival rate of 97.5% (follow-up 99.2%).
- Both fixation methods achieved high long-term implant survival.
Conclusions:
- The BiCONTACT femoral stem exhibits comparable and excellent long-term survival rates for both cemented and uncemented hip arthroplasty.
- The modular design and standardized procedure support bone preservation and successful osteointegration.
- This hip stem system provides a reliable option for total hip replacement.
