A retrospective review of 178 consecutive subtraction hip arthrograms (175 patients) was performed to evaluate the significance of cavities or bursal communications (or both) with the pseudocapsule in patients with painful hip arthroplasty. Bursae and/or communicating cavities were shown in 75 (43%) of the 175 patients. Communicating irregular cavities were noted in 12 patients (nine infected), and smooth bursae or bursalike structures were noted in 63 patients. The most frequent bursal locations were the greater trochanteric region (32/63), supraacetabular region (18/63), and iliopsoas (12/63). Three patients had multiple bursae. Six of the 18 acetabular bursae were associated with previous dislocations. Twenty-seven patients with bursae had no radiographic findings of loosening or infection. Of these 27, 12 (44%) responded to local injection of anesthetic into the bursa and were judged clinically to have bursitis. Arthrography, with aspiration from the bursae or cavities and injection of anesthetic, provides additional information regarding painful hip arthroplasty and may prevent unnecessary surgery.
对连续178例(175例患者)髋关节造影减影片进行回顾性分析,以评估疼痛性髋关节置换患者中腔隙或滑囊与假囊相通(或两者皆有)的意义。175例患者中有75例(43%)显示有滑囊和/或相通腔隙。12例患者(9例感染)可见相通的不规则腔隙,63例患者可见光滑的滑囊或类滑囊结构。最常见的滑囊部位是大转子区(32/63)、髋臼上区(18/63)和髂腰肌(12/63)。3例患者有多个滑囊。18个髋臼滑囊中6个与既往脱位有关。27例有滑囊的患者无松动或感染的影像学表现。在这27例患者中,12例(44%)对向滑囊内局部注射麻醉剂有反应,临床判断为滑囊炎。通过滑囊或腔隙抽吸并注射麻醉剂的关节造影,可为疼痛性髋关节置换提供额外信息,并可能避免不必要的手术。
