Hip-spine relations and sagittal balance clinical consequences

Area of Science:

• Orthopedics
• Radiology
• Spinal Surgery

Background:

• The pelvic area's role in sagittal balance is recognized, but the coxofemoral joint's influence is often underestimated.
• Conventional imaging inadequately explains the interplay between the spine, pelvis, and hip joints.

Purpose of the Study:

• To comprehensively analyze the pelvic and subpelvic sectors in relation to trunk balance.
• To elucidate the connection between spinal diseases and pelvic biomechanics.
• To highlight the importance of the coxofemoral joint in overall spinal health.

Main Methods:

• Utilizing innovative radiologic techniques like EOS® technology.
• Re-evaluating conventional imaging for a deeper analysis.
• Analyzing both standing lateral and seated radiographic images.

Main Results:

• Atypical morphotypes and unusual postures, such as in the aging spine, can cause disturbances.
• Measurement of available extension and the concept of available flexion offer new insights.
• These findings provide information on individual adaptations to spinal or lower limb disorders.

Conclusions:

• Comprehensive assessment of the spine-pelvis complex is crucial.
• Understanding individual adaptations to imbalance is essential for effective treatment.
• This approach sheds light on spinal diseases and their relationship with the pelvis.
