Preserving the femoral neck during total hip arthroplasty (THA) offers biomechanical benefits and improves hip geometry. However, long-term studies are needed to assess bone remodeling and implant survival with neck-preserving stems.
Area of Science:
- Orthopedic Surgery
- Biomedical Engineering
Background:
- Total hip arthroplasty (THA) typically involves femoral neck resection.
- Retaining the femoral neck in THA may offer mechanical and biological advantages.
Purpose of the Study:
- Review evidence on femoral neck preservation benefits in THA.
- Evaluate clinical and radiological outcomes of neck-preserving femoral stems.
Main Methods:
- Literature search of English-language studies on neck-preserving THA.
- Databases searched include PubMed, Ovid SP, and Science Direct.
Main Results:
- Neck preservation enhances implant stability and restores hip biomechanics.
- Bone-conserving implants with neck preservation show promising early results.
- Proximal femoral bone loss and distal cortical hypertrophy observed in some implants require further investigation.
Conclusions:
- Femoral neck preservation in THA provides biomechanical advantages.
- Long-term data are essential for evaluating bone remodeling and survival of neck-preserving stems.
