Femoroacetabular Impingement (FAI): This condition is a common cause of anterior hip pain, especially in young adults. It occurs when there is abnormal contact between the femoral head and the acetabulum, leading to pain and limited mobility.

Hip Flexor Strain: Strains to the hip flexor muscles, such as the iliopsoas, can cause anterior hip pain, especially with activities that involve hip flexion.
Osteoarthritis: Hip osteoarthritis can cause anterior hip pain, especially with weight-bearing activities, due to the degeneration of the joint cartilage.
Labral Tear: A tear in the labrum, the cartilage that surrounds the socket of the hip joint, can cause anterior hip pain, especially with twisting or pivoting movements.
Bursitis: Inflammation of the bursae, the fluid-filled sacs that cushion the joints, can cause anterior hip pain, especially with activities that involve hip flexion.

Septic Arthritis: This is a serious infection of the joint that requires prompt treatment to prevent long-term damage. It can cause severe anterior hip pain, fever, and limited mobility.
Avascular Necrosis: This condition occurs when the blood supply to the femoral head is disrupted, leading to necrosis of the bone tissue. It can cause anterior hip pain, especially with weight-bearing activities.
Stress Fracture: A stress fracture of the femoral neck or pelvis can cause anterior hip pain, especially with weight-bearing activities.

Piriformis Syndrome: This condition occurs when the piriformis muscle compresses the sciatic nerve, causing pain and numbness in the hip and leg.
Snapping Hip Syndrome: This condition occurs when the iliopsoas tendon snaps over the femoral head, causing a snapping sound and anterior hip pain.
Inflammatory Arthritis: Conditions such as rheumatoid arthritis or lupus can cause anterior hip pain, especially with systemic symptoms such as fever and fatigue.
