[Modified Salter innominate osteotomy in adults].

Area of Science:

• Orthopedic Surgery
• Hip Dysplasia Research
• Skeletal Maturity Studies

Background:

• Acetabular dysplasia involves outward and forward displacement of the acetabulum.
• Symptomatic residual hip dysplasias and subluxations require effective surgical correction in skeletally mature patients.

Purpose of the Study:

• To evaluate the efficacy of acetabular osteotomy in correcting hip dysplasia.
• To assess the three-dimensional correction of the dysplastic acetabulum.

Main Methods:

• The study included skeletally mature patients up to 50 years with symptomatic hip dysplasia or subluxation.
• A supine ilioinguinal approach was used, involving division of the innominate bone and correction via the Salter maneuver.
• Bone grafting and internal fixation with screws and threaded rods were performed.

Main Results:

• Forty-five patients (49 hips) underwent surgery, with an average age of 27.6 years.
• Significant improvements were observed in the Sharp acetabular angle, Wiberg (LCE) angle, and anterior center edge (ACE) angle.
• Complications requiring surgical intervention occurred in 7 patients.

Conclusions:

• Acetabular osteotomy is an effective surgical treatment for hip dysplasia in adults.
• The procedure leads to significant improvements in hip joint geometry and stability.
• Further research may explore long-term outcomes and complication rates.
