Adhesive capsulitis of the hip.

Abstract

Adhesive capsulitis of the hip (ACH) is not a well-defined disease entity. We evaluated the change in the clinical features of patients whose chief complaint was inability to sit cross-legged on the floor. All patients had painful limitation in hip joint motion. Based on the diagnosis of ACH, active stretching exercise (ASE) was recommended. In February 2013 and June 2014, a total of 44 patients (50 hips), who visited outpatient clinic in 2011, were evaluated by telephone interviews. Recovery of hip motion was analyzed according to compliance with ASE and abnormalities found on plane radiographs and magnetic resonance (MR) images. There were 27 women and 17 men with mean age of 51.7 years. In the first telephone interview, 40 patients (45 hips) reported improvement in hip motion but 4 patients (5 hips) reported absolutely no improvement. Compliance with ASE did not affect recovery of motion ( p = 0.225). On plain radiographs, 10 patients (22.7%) had abnormal finding in both hips. Those abnormal findings were not correlated with symptom and did not show adverse effect on motion recovery. Sixteen patients took MR images outside, and abnormal findings such as round ligament or labral tear were observed in nine patients. Those abnormal findings neither correlated with the symptom nor affected motion recovery adversely. In the second telephone interview, nine hips of further improvement and two hips of recurrence were identified. Most cases showed improvement in the range of motion with or without ASE. Surgical treatments including arthroscopy seemed to be unnecessary for these patients.
