Applications in hip pathology

Area of Science:

• Orthopedics and Biomechanics
• Spinal and Hip Joint Pathologies

Background:

• Clinical observations suggest a strong relationship between lumbar spine and hip joint function.
• The lumbar-pelvic-femoral complex acts as a dynamic unit, transmitting stresses between the spine and lower limbs.
• Hip pathologies like congenital dislocation and ankylosis significantly impact spinal alignment and mechanical strain.

Purpose of the Study:

• To explore the intricate relationship between spinal and hip joint biomechanics.
• To emphasize the importance of considering the entire lumbar-pelvic-femoral complex in hip joint treatment strategies.
• To discuss the implications of various hip pathologies on spinal health and posture.

Main Methods:

• Clinical analysis of patient presentations.
• Utilizing infiltration tests and imaging for diagnostic support.
• Review of biomechanical principles governing the lumbar-pelvic-femoral complex.

Main Results:

• Congenital hip dislocation and ankylosis impose significant mechanical strain and spinal malalignment.
• Femoro-acetabular impingement, while linked to hip joint abnormalities, shows no association with abnormal spinal or pelvic parameters.
• Congenital pelvic tilt in children presents unique challenges for achieving spinal and pelvic balance, especially in cases of childhood palsy.

Conclusions:

• A comprehensive assessment of the lumbar-pelvic-femoral complex, including the knee, is crucial before total hip replacement.
• Understanding the interplay between hip and spine is vital for effective management of diverse hip pathologies.
• Addressing spinal and pelvic balance is critical in managing children with pelvic tilt and associated neurological conditions.
