Summary
This transtrochanteric hip approach preserves greater trochanter continuity, preventing displacement and protecting blood vessels. It offers excellent bone union rates and good abductor function, making it suitable for complex hip replacements.
Area of Science:
- Orthopedic Surgery
- Hip Arthroplasty
Background:
- The transtrochanteric approach is a surgical technique for hip procedures.
- Maintaining the integrity of the greater trochanter and its vascular supply is crucial for successful hip surgery.
Purpose of the Study:
- To evaluate the efficacy and outcomes of a transtrochanteric approach that maintains continuity between the greater trochanter and the vastus lateralis muscle.
- To assess the rate of bony union, trochanteric displacement, and abductor function associated with this surgical technique.
Main Methods:
- A transtrochanteric surgical approach was utilized in 189 consecutive hip operations.
- The technique focused on preserving the continuity of the greater trochanter and the vascular supply from the lateral circumflex vessels.
Main Results:
- A high rate of bony union between the trochanter and femur was observed, with non-union occurring in only four cases (2.1%).
- Cranial displacement of the greater trochanter was consistently less than three cm.
- Good abductor power was maintained even in cases with non-union.
Conclusions:
- The transtrochanteric approach, preserving greater trochanter continuity, demonstrates a high success rate for bony union and preserves abductor function.
- This technique is advantageous for hip replacement, particularly in cases anticipated to present technical challenges.
