Iliopsoas bursitis (IB) is a relatively rare condition that is associated with hip diseases. It can cause neurological symptoms and swelling of the lower extremities by compressing the femoral nerve and vessels. The aim of this study is to examine the prevalence of IB in patients with end-stage hip osteoarthritis.
A total of 544 patients underwent total hip arthroplasty between May 2010 and May 2019. All patients were examined using computed tomography (CT) to perform preoperative planning. We reviewed the CT images and examined the prevalence and size of IB. These lesions were divided into three types based on their shape (round type, oval type, and heart-shaped type).
Of the 544 patients, IB was found in 37 patients. We observed the round type in 4 patients, the oval type in 31 patients, and the heart-shaped type in 2 patients. Two patients showed severe swelling in the legs and had a blood circulatory disorder of the legs. Both cases were heart-shaped bursitis.
Symptomatic IB was observed in two cases, both of which had a heart shape surrounding the iliopsoas tendon and femoral neurovascular bundle. Although symptomatic IB is a rare condition, special attention is required for heart-shaped IB.
腰大肌滑囊炎（IB）是一种与髋关节疾病相关的相对罕见的病症。它可通过压迫股神经和血管导致下肢神经症状和肿胀。本研究旨在探讨终末期髋关节骨关节炎患者中 IB 的患病率。
2010 年 5 月至 2019 年 5 月期间，共有 544 例患者接受了全髋关节置换术。所有患者均接受了计算机断层扫描（CT）检查，以进行术前规划。我们回顾了 CT 图像，并检查了 IB 的患病率和大小。根据其形状（圆形、椭圆形和心形）将这些病变分为三种类型。
在 544 例患者中，发现 37 例存在 IB。我们观察到 4 例为圆形，31 例为椭圆形，2 例为心形。2 例患者出现腿部严重肿胀，腿部血液循环障碍。这两种情况均为心形滑囊炎。
有 2 例出现症状性 IB，均为心形，围绕腰大肌肌腱和股神经血管束。虽然症状性 IB 较为罕见，但需特别注意心形 IB。
