[Bernese periacetabular osteotomy (Ganz procedure). First experience].

Area of Science:

• Orthopedic surgery
• Hip reconstruction
• Acetabular dysplasia treatment

Context:

• Developmental dysplasia of the hip (DDH) can lead to acetabular dysplasia after skeletal maturity.
• The Bernese periacetabular osteotomy (Ganz procedure) is increasingly used for adult hip reconstruction.
• Evaluating the initial outcomes of this technique is crucial for understanding its efficacy.

Purpose:

• To evaluate the initial results of Bernese periacetabular osteotomy for treating residual acetabular dysplasia in adults.
• To assess the effectiveness of the Ganz procedure in improving hip joint parameters post-bone maturation.

Summary:

• The study analyzed 25 hips in 22 patients (average age 26) undergoing Bernese periacetabular osteotomy for hip dysplasia or spastic hip.
• Pre- and post-operative radiographs showed significant improvements in the AC index, Wiberg lateral CE angle, and Wagner index.
• Shenton's line was corrected in 20 hips, and lateral migration was reduced in 16 hips, with an average follow-up of 18 months.

Impact:

• Bernese periacetabular osteotomy offers a valuable surgical option for adult hip joint treatment, expanding the range of available procedures.
• The procedure demonstrates potential for significant radiographic improvement in hip joint alignment.
• Successful outcomes necessitate specialized centers and experienced surgical teams due to the procedure's complexity and potential complications.
