Hip Anatomy

By General Info

The hip is made up where the thigh bone meets the pelvis to form a ball-and-socket joint.

The hip joint consists of two main parts:

1) Femoral head – a ball-shaped piece of bone located at the top of your thigh bone, or femur

2) Acetabulum – a socket in your pelvis into which the femoral head fits

Bands of tissue, called ligaments, connect the ball to the socket, stabilizing the hip and forming the joint capsule. The synovium is a thin membrane that lines to joint capsule. This membrance produces a viscous fluid to lubricate the joint. Fluid-filled sacs called bursae provide cushioning where there is friction between muscle, tendons and bones.
Large muscles surround the hip and support the joint and enable movement.

They include:

  • Gluteal muscles – muscles of the buttocks, located on the back of the hip
  • Adductor muscles – muscles of the inner thigh, which pull the leg inward
  • Iliopsoas muscle – a muscle that begins in the lower back and connects to the upper femur
  • Quadriceps – four muscles on the front of the thigh that run from the hip to the knee
  • Hamstrings – muscles on the back of the thigh, which run from the hip to just below the knee
