 Background:The aim of the present study was to investigate the relationships between neuropathic pain and the hip function of patients with hip osteoarthritis.

 Methods:The subjects of this study were 89 patients with osteoarthritis of the hip (94 hips). The subjects were evaluated based on their neuropathic pain score (NP score) and the Japanese Orthopaedic Association hip rating score (JOA hip score).

 Results:According to the NP scores the subjects experienced moderate or severe neuropathic pain in 30% of the hips. There was a significant correlation between the NP scores and the JOA hip scores.

 Conclusions:The results of this study suggest that hip-osteoarthritis-related pain can be attributed to both nociceptive pain and neuropathic pain. The neuropathic pain may also affect hip function.
