A partial osteotomy of the greater trochanter enhances hip joint stability after posterior approach surgery, significantly reducing dislocation risk. This technique proves reliable for stable hip replacements.

Area of Science:

  • Orthopedic Surgery
  • Biomechanical Engineering

Background:

  • Posterior hip dislocation is a known complication of the posterior surgical approach.
  • Improving hip joint stability and reducing dislocation risk are critical goals in hip replacement surgery.

Purpose of the Study:

  • To evaluate a modified posterior hip approach using partial osteotomy of the greater trochanter.
  • To determine if this technique enhances hip joint stability and decreases dislocation incidence.

Main Methods:

  • A partial intertrochanteric osteotomy was performed, with the fragment reattached using wires.
  • Surgical procedures included total hip replacement in 68 patients (30 with femur fractures, 38 with osteoarthritis).
  • Intraoperative stability testing and one-year clinical follow-up were conducted.

Main Results:

  • Hip dislocation points increased by over 15% in flexion and 10% in internal rotation post-osteosynthesis.
  • No dislocations were reported during the one-year follow-up period in the patient cohort.

Conclusions:

  • Partial osteotomy of the greater trochanter is a reliable technique for achieving a stable hip joint.
  • This approach effectively reduces the risk of dislocation following posterior hip surgery.
