Differential diagnosis and early management of rapidly progressing hip pain in a 59-year-old male.

OBJECTIVE AND IMPORTANCE: Rapidly progressing degeneration of the hip joint is an uncommon condition presenting to physical therapy. Differential diagnosis can often be difficult, as clinical and radiographic findings do not always coincide leaving clinicians with difficult decision making regarding course of treatment. The purpose of this case report was to describe the differential diagnosis and early management of a patient with rapidly progressing hip pain. CLINICAL
PRESENTATION: A 59-year-old male with a complicated medical history was referred with a diagnosis of severe bilateral hip osteoarthritis. Clinical presentation of insidious onset, severe bilateral groin and anterior thigh pain with rapid progression of functional decline lead to the differential diagnosis of bilateral avascular necrosis. INTERVENTION: The patient received seven manual physical therapy sessions over the course of one month.
CONCLUSION: During this time, the patient's Lower Extremity Functional Scale score worsened from 33 to 21. The persistence of the patient's painful symptoms and continued functional decline helped determine cessation of manual therapy and referral back to his GP for further diagnostic testing and eventual correct diagnosis. This case highlights the importance of monitoring patient prognosis using outcome measures leading to a change in patient management strategies.
