Summary
This study modifies acetabular osteotomy to preserve the tensor fascia lata muscle and provide bone graft material. The technique enhances acetabular reorientation while maintaining muscle integrity and enabling bone reconstruction.
Area of Science:
- Orthopedic Surgery
- Surgical Techniques
- Hip Reconstruction
Background:
- Acetabular osteotomy is used for acetabular reorientation without altering diameter.
- Previous methods may compromise surrounding soft tissues and bone graft availability.
Purpose of the Study:
- To present a modified acetabular osteotomy technique.
- To preserve the tensor fascia lata muscle during surgery.
- To utilize anterior iliac osteotomy site bone for grafting.
Main Methods:
- A surgical approach is developed between the sartorius and tensor fascia lata muscles.
- The anterosuperior iliac spine is osteotomized.
- A segment of the anterosuperior iliac spine with a tensor fascia lata slip is harvested.
- This segment is shaped for the anterior bone gap and secured with sutures after drilling holes.
Main Results:
- The modified technique preserves the tensor fascia lata muscle's anatomical integrity.
- Viable bone for grafting is obtained from the anterior iliac osteotomy site.
- The acetabular segment is effectively utilized for anterior bone gap reconstruction.
Conclusions:
- This modification offers an improved acetabular osteotomy procedure.
- It successfully preserves key muscles and provides autologous bone graft.
- The technique facilitates acetabular reorientation with enhanced tissue preservation.
