Addition of bupivicaine, a medium-length-acting local anesthetic, to the contrast material in arthrography of total hip prostheses provides reliable information as to whether the source of pain is intracapsular or extracapsular. In 12 surgically proven cases, complete relief of pain after bupivicaine injection correctly identified an intracapsular source of pain in 10, with only 1 false-positive and 1 false-negative. These results compare favorably with the results of the contrast arthrograms in these patients in localizing the pain even if a specific diagnosis could not be reached. Bupivicaine as an adjunct to contrast material during arthrography provides additional information useful in management decisions regarding the necessity of revision arthroplasty.
在全髋关节假体造影术中，向造影剂中添加布比卡因（一种中效局部麻醉剂），可就疼痛来源是关节囊内还是关节囊外提供可靠信息。在12例经手术证实的病例中，注射布比卡因后疼痛完全缓解，正确识别出10例关节囊内疼痛来源，仅有1例假阳性和1例假阴性。即便无法得出具体诊断结果，这些结果在确定这些患者疼痛部位方面，与造影关节造影的结果相比仍更具优势。在造影术中，布比卡因作为造影剂的辅助剂，可为有关翻修关节成形术必要性的管理决策提供有用的额外信息。
