The hip joint: structure, stability, and stress; a review.

Area of Science:

• Orthopedics
• Biomechanics
• Anatomy

Background:

• The hip joint's structural integrity is crucial for stability.
• Understanding biomechanical forces is key to hip function.

Purpose of the Study:

• To review hip joint structure in relation to stability.
• To discuss forces acting on the hip during normal activities and in abnormalities.

Main Methods:

• Literature review of hip joint anatomy and biomechanics.
• Analysis of forces on the proximal femur during standing and gait.
• Review of clinical considerations for hip abnormalities.

Main Results:

• Hip joint stability is intrinsically linked to its anatomical structure.
• Normal stresses during standing and gait are influenced by bone position.
• Abnormalities like coxa valga, coxa vava, arthritis, and fracture alter mechanical forces.

Conclusions:

• Hip structure dictates joint stability.
• Altered mechanical forces in hip abnormalities can lead to instability and pain.
• Understanding these biomechanical principles is vital for clinical management.
