背景资料：全髋关节置换术（THA）后慢性髋关节疼痛是一个重要问题，但病因尚不清楚。目的：确定THA术后3年慢性髋关节疼痛患者的感觉功能。方法：对18例慢性髋关节疼痛患者和18例非慢性髋关节疼痛对照者进行全髋关节置换术后髋关节疼痛的问卷调查。所有参与者回答有关疼痛和精神脆弱性的问题，并进行了临床检查，然后进行定量感觉测试（刷诱发的异常性疼痛，针刺痛觉过敏，机械和热thresholds.Results：刷诱发的异常性疼痛存在于4例髋关节疼痛（P = 0.1）和针刺痛觉过敏（P = 0.02）更频繁的慢性髋关节疼痛患者。患者和对照组的机械和热阈值相似。慢性髋关节疼痛患者的心理脆弱性量表得分较高（P <0.001）。慢性髋关节疼痛与腰痛显著相关（P = 0.002）。结论：我们发现了手术侧的超敏反应迹象，这在疼痛患者中更为突出。来自背部或髋关节深层结构的疼痛似乎在患者亚组的疼痛中起作用。此外，慢性髋关节疼痛与精神脆弱性有关。(C)2008年，国际疼痛研究协会欧洲分会联合会。由爱思唯尔有限公司出版。保留所有权利。
Background: Chronic hip pain after total hip arthroplasty (THA) is a significant problem, but the aetiology remains unclear.Aims: To determine sensory function in patients with chronic hip pain 3 years after THA. Patients without hip pain after THA served as controls.Methods: Eighteen patients with chronic hip pain and 18 controls without chronic hip pain were recruited from a previous questionnaire study about hip pain after total hip arthroplasty. All participants answered questions about pain and mental vulnerability and underwent clinical examination followed by quantitative sensory testing (brush-evoked allodynia, pinprick hyperalgesia, mechanical and thermal thresholds).Results: Brush-evoked allodynia was present in 4 patients with hip pain (P = 0.1)and pinprick hyperalgesia (P = 0.02) was more frequent in patients with chronic hip pain. Mechanical and thermal thresholds were similar in patients and controls. Patients with chronic hip pain had higher scores on the mental vulnerability scale (P < 0.001). Chronic hip pain was significantly associated with low back pain (P = 0.002). Conclusions: We found signs of hypersensitivity on the operated side, which was more prominent in patients with pain. Pain referred from the back or deeper structures in the hip seems to play a role for the pain in subgroups of patients. In addition, chronic hip pain was associated with mental vulnerability.
