Surgical dislocation of the hip without trochanteric osteotomy

Area of Science:

• Orthopedic Surgery
• Hip Preservation Surgery

Background:

• Surgical hip dislocation is a key procedure in hip preservation when dynamic access is needed and arthroscopy is unsuitable.
• A novel technique for operative hip dislocation without trochanteric osteotomy is presented.

Purpose of the Study:

• To describe a novel technique for surgical hip dislocation without trochanteric osteotomy.
• To evaluate the clinical outcomes of patients undergoing this modified procedure.

Main Methods:

• A modified lateral approach was utilized for surgical hip dislocation without trochanteric osteotomy.
• Demographic, clinical, and radiological data were reviewed for patients operated between 2010 and 2015.
• Complications, mobility, weight-bearing status, and modified Harris Hip Score (mHHS) were recorded.

Main Results:

• Six surgical hip dislocations were performed, primarily for tumor resection (5 hips) and bullet extraction (1 hip).
• The patient cohort included 4 hips in 2 women and 2 hips in 2 men, with a mean age of 19 ± 3.8 years.
• Median follow-up was 2.5 years, with a median mHHS of 92. No intraoperative or postoperative complications were reported.

Conclusions:

• Surgical hip dislocation without trochanteric osteotomy via a modified lateral approach is a safe and effective alternative.
• This technique simplifies the procedure while maintaining efficacy in hip preservation surgery.
