Bones of the Lower Limb: Femur and Patella01:16

Bones of the Lower Limb: Femur and Patella

The femur is the body's longest and strongest bone spanning the thigh region. Its head articulates with the acetabulum of the hip bone to form the hip joint. A minor indentation on the medial side of the femoral head, called the fovea capitis, serves as the site of attachment for the ligament of the head of the femur. This weak ligament spans the femur and acetabulum and supports the hip joint. The narrowed region below the head is the neck of the femur. The inclination angle between the neck...

Summary

This study evaluated proximal and total femur replacements for bone defects, finding periprosthetic infections and dislocations as key complications. Functional outcomes were varied, highlighting the complexity of these reconstructive surgeries.

Area of Science:

  • Orthopedic Surgery
  • Oncology
  • Biomedical Engineering

Background:

  • Reconstruction of proximal femur bone defects is challenging.
  • Tumor resection and revision arthroplasty create significant bone loss.
  • Advanced prosthetics are crucial for restoring function.

Purpose of the Study:

  • To assess the outcomes of proximal and total femur replacements.
  • To evaluate the efficacy of these procedures for tumor resection and revision arthroplasty.
  • To identify complications and functional results in patients undergoing femur reconstruction.

Main Methods:

  • Retrospective review of 22 patients (20 proximal, 2 total femur replacements).
  • Surgical technique involved anterolateral approach and prosthesis implantation.
  • Postoperative management included infection prophylaxis and partial weight bearing.

Main Results:

  • 22 patients (mean age 62.0 ± 18.1 years) were analyzed.
  • Complications included periprosthetic infection (13.6%) and dislocation (9.1%).
  • Functional outcomes (MSTS score) showed 20% very good, 26.7% good, 40% fair, and 13.3% poor results.

Conclusions:

  • Femur replacement is a viable option for extensive proximal femur defects.
  • Careful patient selection and surgical technique are essential.
  • Further research is needed to optimize functional outcomes and minimize complications.
