Preoperative planning for redirective, periacetabular osteotomies

Area of Science:

• Orthopedic surgery
• Hip biomechanics
• Radiology

Background:

• Developmental dysplasia of the hip (DDH) requires surgical intervention for symptom reduction and osteoarthritis prevention.
• The femoroacetabular impingement concept has enhanced understanding of DDH's complex 3D nature.
• Improved diagnostic tools allow for detailed analysis of dysplastic hips.

Purpose of the Study:

• To review current imaging techniques for DDH.
• To discuss preoperative planning strategies for PAO.
• To provide treatment recommendations for PAO in DDH.

Main Methods:

• Literature review of imaging modalities for DDH.
• Analysis of preoperative planning in PAO.
• Evaluation of diagnostic tools including conventional radiography and advanced imaging.

Main Results:

• Conventional radiography remains essential for DDH diagnosis.
• Advanced imaging like biochemical MRI aids in assessing early cartilage degeneration.
• 3D planning and virtual simulation enhance PAO preparation.

Conclusions:

• Sophisticated preoperative analysis is vital for technically demanding PAO.
• Modern imaging techniques improve the understanding and planning of PAO for DDH.
• Personalized treatment based on patient-specific deformities optimizes PAO outcomes.
