title: Iliopsoas tendonitis due to the protrusion of an acetabular component fixation screw after total hip arthroplasty.
abstract: Postoperative pain after total hip arthroplasty can have a wide range of underlying causes. Iliopsoas tendonitis secondary to the impingement of this tendon is a relatively rare cause of pain after arthroplasty. This condition is characterized by pain on active flexion and an absence of signs or symptoms of loosening or infection. In this report, we describe the case of a patient who had signs and symptoms of iliopsoas tendonitis secondary to the protrusion of an acetabular fixation screw through the ilium after primary total hip arthroplasty. Nonoperative treatment was ineffective, and the patient ultimately underwent surgical removal of the screw. The severity of the patient's symptoms decreased significantly after the operation.
