A new PA student presents with lateral hip pain, especially with abduction at night. What condition is she most likely experiencing?

• A. Osteoarthritis
• B. Trochanteric bursitis
• C. Avascular necrosis
• D. Labral tear

Answer: (B)

The condition most likely being experienced by the PA student is trochanteric bursitis. This condition is characterized by inflammation of the bursa located over the greater trochanter of the femur, and it commonly presents with lateral hip pain. The pain is typically exacerbated by activities such as hip abduction and is often more pronounced at night when lying on the affected side.

In the context of lateral hip pain, especially with abduction, trochanteric bursitis aligns with common clinical manifestations. Patients often report difficulty with activities that involve movement of the hip, such as walking, climbing stairs, or even lying in certain positions during sleep. The location of the pain and its association with specific movements makes this condition the most likely diagnosis for the student.

Other conditions mentioned, such as osteoarthritis, avascular necrosis, and labral tears, might present with hip pain but usually have additional symptoms or a different pain pattern. Osteoarthritis typically involves joint stiffness and pain that worsens with weight-bearing activities. Avascular necrosis may present with more diffuse hip pain and is often associated with a history of trauma or certain risk factors. A labral tear can present with a catching or locking sensation, alongside pain, rather than the specific lateral pain
