We investigated 42 patients who were being considered for primary total hip arthroplasty (THA), but in whom it was uncertain whether the hip was the source of their pain. They were given an injection of local anaesthetic into the joint space. Of 33 patients who gained pain relief from their injection, 32 subsequently had successful THA. The remaining patient has not had surgery. The intra-articular injection of local anaesthetic is thus at least 96% sensitive. Of the nine patients who had no or only minimal pain relief from injection, one has had an unsuccessful THA, three have been successfully treated for other conditions and five have unresolved pain for which no organic basis has been established. We believe that the injection of local anaesthetic into the hip is a reliable test, with low morbidity. In difficult cases it will aid in the clarification of the cause of pain which possibly arises from the hip.
我们对42例正在考虑接受初次全髋关节置换术（THA）的患者进行了研究，但这些患者的髋部是否为疼痛来源尚不确定。我们向他们的关节腔注射了局部麻醉剂。在33例注射后疼痛缓解的患者中，32例随后成功进行了全髋关节置换术。其余1例患者尚未接受手术。因此，关节腔内注射局部麻醉剂的敏感性至少为96%。在9例注射后疼痛未缓解或仅轻微缓解的患者中，1例全髋关节置换术失败，3例因其他病症得到成功治疗，5例疼痛未得到解决且未发现器质性病因。我们认为，向髋部注射局部麻醉剂是一项可靠的检查，发病率低。在疑难病例中，它有助于明确可能源于髋部的疼痛原因。
