Femoroacetabular Impingement (FAI): This condition is characterized by abnormal contact between the femoral head and the acetabulum, leading to pain in the anterior hip and groin area, especially with flexion and internal rotation of the hip. It's a common cause of hip pain in young, active adults.

Hip Flexor Strain: Strains to the hip flexor muscles, such as the iliopsoas, can cause anterior hip pain that may radiate to the groin. This is often seen in athletes who participate in sports that involve sprinting or kicking.
Osteitis Pubis: Inflammation of the pubic bone and its surrounding structures can cause pain in the groin area that may radiate to the anterior hip. This condition is common in athletes involved in sports that require repetitive kicking or quick changes of direction.
Stress Fracture of the Femoral Neck: A stress fracture in this area can cause anterior hip pain that may radiate to the groin, especially with weight-bearing activities. It's more common in long-distance runners or athletes with poor bone density.

Hip Fracture: Although less common in younger populations, a fracture of the hip (such as a femoral neck fracture) can present with anterior hip pain radiating to the groin. Missing this diagnosis can lead to significant morbidity and mortality, especially in the elderly.
Avascular Necrosis of the Femoral Head: This condition, where the blood supply to the femoral head is interrupted, can cause hip pain. It's a critical diagnosis not to miss because early treatment can prevent collapse of the femoral head and preserve hip function.
Septic Arthritis of the Hip: An infection within the hip joint can cause severe pain, swelling, and reduced range of motion. This is a medical emergency that requires prompt diagnosis and treatment to prevent long-term damage to the joint.

Psoas Abscess: A collection of pus in the psoas muscle can cause hip pain that radiates to the groin, along with systemic symptoms like fever. This condition is rare but serious and requires prompt medical attention.
Intra-abdominal Pathology (e.g., Appendicitis, Diverticulitis): Although rare, intra-abdominal conditions can sometimes refer pain to the groin and anterior hip area. A thorough abdominal examination and diagnostic workup are essential to rule out these conditions.
Spinal Pathology (e.g., Lumbar Disc Herniation): Certain spinal conditions can cause referred pain to the hip and groin area. A detailed neurological examination and possibly imaging of the spine may be necessary to diagnose these conditions.
