Smaller projection on the femur where the iliopsoas muscle attaches

Ridge on the posterior femur where adductor muscles attach

Triangular bone formed by the fusion of 4-5 vertebrae that connects the spine to the pelvis

Ball-and socket joint between the femur and pelvis that allows multi-directional movement

Joint between the sacrum and ilium that stabilizes the pelvis

Hip flexor muscle located in the iliac fossa

Powerful hip flexor connecting the spine to the femur

Quadriceps muscle that flexes the hip and extends the knee

Long muscle that flexes, abducts, and laterally rotates the hip

Muscle that assists with hip flexion and adduction

Quadriceps muscle responsible for knee extension and patellar stabilization

Long medial thigh muscle assisting hip adduciton and knee flexion

Strong ligament that prevents hyperextension of the hip

Another name for the iliofemoral ligament and the strongest hip ligament

Ligament that limits hip abduction and extension

ligament that stabilizes the posterior hip joint

ligament that carries blood supply to the femoral head

Ring of cartilage that deepens the hip socket for stability

Fluid-filled sac that reduces friction near the greater trochanter

Movement moving the leg away from the midline (about 45)

Movement moving the leg toward the midline (about 70)

Rotation of the femur inward (about 35)

Rotation of the femur outward (about 45)

Break in the middle portion of the femur usually caused by high force trauma

Sever pain, swelling, deformity, muscle guarding, and shortened externally rotated leg

Break near the femoral head that can lead to avascular necrosis

Death of bone tissue due to loss of blood supply

Displacement of the femoral head from the acetabulum

Most common hip dislocation where the femoral head moves backward

Tear of the hamstring muscles often due to sudden acceleration or overstretching
