The hip joint is the proximal joint of the lower limb, responsible for balance, and is a ball-and-socket joint with three degrees of freedom, making it very mobile.

Hip joint is the second most mobile joint in the body, allowing for a wide range of movement, but its unique structure means it cannot be fully dislocated by external forces.

The hip joint's 'functional position' is a slight flexion and external rotation, crucial for optimal posture and movement.

The psoas major muscle is the key player in flexing the hip and rotating it externally.

The gluteus maximus muscle is responsible for hip extension and external rotation.

A test where the patient lies on their back and brings the opposite knee to their chest. It's positive if the tested leg lifts off the ground and indicates a shortened or snapping psoas muscle.

This test assesses the position of the hips during squatting and lunging. An exaggerated internal or external rotation during these movements can indicate hip anteversion or retroversion, or muscle weakness.

This test involves two variations to assess the strength of the gluteus muscles. For the gluteus major, the patient is prone with a flexed knee, pushing against resistance during external hip rotation. For the gluteus medius, the patient is in a side-lying position with a flexed knee, abducting the hip against resistance.

This test involves the patient sitting with knees stretched, flexing the opposite knee and reaching towards the toes without touching. The distance between the fingers and toes indicates hamstring flexibility.

This test involves the patient sitting with knees stretched, flexing the opposite knee and reaching towards the toes without touching. The distance between the fingers and toes indicates hamstring flexibility.

The hip joint is a ball-and-socket joint with 3 degrees of freedom. It's the most mobile joint in the body besides the shoulder, and the only one that cannot be dislocated by external forces.

Internal rotation is when the femur rotates inward, towards the midline of the body. External rotation is when the femur rotates outward, away from the midline.

The gluteus maximus is essential for keeping us upright and involved in many daily movements.

The psoas major is a powerful hip flexor and external rotator, aiding in movements like bringing the leg up towards the body.

The TFL is involved in several hip movements, including flexion and abduction, making it crucial for dynamic movements.

In this test, the patient lies on their back and brings the opposite knee to their chest. If the tested leg lifts off the ground, it indicates a shortened or snapping psoas muscle.

This test evaluates the hip's rotation during squats and lunges. If the hip rotates excessively inward or outward, it may indicate hip anteversion, retroversion, or muscle weakness.

The two variations of the Gluteal Test assess the strength of the gluteus maximus and medius muscles. It involves pushing against resistance during external hip rotation (gluteus maximus) or hip abduction (gluteus medius).

This test involves the patient sitting with straight legs, then flexing the opposite knee and reaching towards the toes without touching them. The distance between the fingers and toes indicates hamstring flexibility.

This test evaluates hip rotation during movements like squatting and lunging. It's positive if the hip rotates excessively inward or outward, which may indicate hip anteversion or retroversion.
