Trochanteric osteotomy and wire fixation: a comparison of 2 techniques

Area of Science:

• Orthopedic Surgery
• Biomedical Engineering
• Rheumatology

Background:

• Osteoarthritis and posttraumatic arthritis are common indications for total hip replacement.
• The transtrochanteric approach is a surgical technique used in total hip arthroplasty.
• Trochanteric osteotomy and reattachment are critical steps influencing hip replacement outcomes.

Purpose of the Study:

• To compare the union rates of trochanteric osteotomies between biplane and single plane techniques.
• To evaluate the impact of different osteotomy techniques on the success of cemented Charnley total hip replacement.

Main Methods:

• A retrospective study involving 190 patients (214 hips) undergoing cemented Charnley total hip replacement.
• Patients were surgically treated between 1986 and 1989 using either a biplane or single plane transtrochanteric approach.
• Surgical technique was standardized except for the trochanteric osteotomy and reattachment method.

Main Results:

• No statistically significant difference in trochanteric union rates was observed between the biplane and single plane osteotomy groups.
• The nonunion rate at the 1-year evaluation was 6.4% in the biplane group and 6.2% in the single plane group.
• Both techniques yielded comparable outcomes regarding trochanteric bone healing.

Conclusions:

• The choice between biplane and single plane trochanteric osteotomy does not significantly affect union rates in cemented Charnley total hip arthroplasty.
• Other factors may play a more substantial role in the rate of trochanteric union following total hip replacement.
• This finding suggests flexibility in surgical technique selection for this specific procedure.
