Introduction

Nociceptive and neuropathic components both contribute to chronic pain. Since these components require different pain management strategies, correct pain diagnosis before and during treatment is important.

Freynhagen et al. (2006) reported that they had developed and validated the pain-DETECT questionnaire (PD-Q) to detect neuropathic components in chronic low back pain patients. They also reported that 37% of unselected cohort of chronic LBP patients had predominantly neuropathic pain. However, the extent to which neuropathic components relate to the pathomechanism of pain deriving from osteoarthritis of hip joint remains unknown.

The purpose of this study was to utilize PD-Q to investigate the relationship between neuropathic components and pain deriving from osteoarthritis of the hip joint.

Methods

Between March and August 2010, 125 patients with osteoarthritis of hip joint completed PD-Qs about their pain. From this data set, we investigated whether or not the patients’ pain contained neuropathic components.

Introduction

The purpose of this study was to clarify the incidence of steroid-induced osteonecrosis among different collagen diseases and to evaluate the predictive factors for steroid-induced osteonecrosis in a prospective MRI study.

Methods

We prospectively used MRI to study 337 eligible collagen disease patients requiring corticosteroid therapy and succeeded in examining 1199 joints (hips and knees) in 302 patients with MRI for at least one year starting immediately after the onset of corticosteroid therapy, a one-year follow-up rate of approximately 90%. The underlying collagen diseases included systemic lupus erythematosus (SLE) in 687 joints and a variety of other collagen diseases in 512 joints.
