Abstract：
Calcific tendinitis of the rectus femoris is rare. This clinical report presents five cases of management of calcific tendinitis of the rectus femoris. Between July 2018 and March 2023, five patients visited our institution, where they were treated for calcific tendinitis of the rectus femoris. All patients presented with severe acute hip pain. Radiographs, computed tomography, magnetic resonance imaging, and an ultrasound examination of the hip showed calcification outside the joint, suggesting calcific tendinitis of the rectus femoris. All patients were orally administered 200 mg cimetidine and nonsteroidal anti-inflammatory drugs twice daily. A pain-free status was achieved in 2 weeks on average. Calcium deposits disappeared in three patients and decreased in two. Symptoms did not recur. Furthermore, no recurrence or enlargements in calcium deposits were observed. It appears to be an effective treatment for calcific tendinitis of the rectus femoris; however, the underlying mechanisms of action of cimetidine on calcific tendinitis have not yet been elucidated in detail.
摘要：
股直肌钙化性肌腱炎是罕见的。本临床报告介绍了5例股直肌钙化性肌腱炎的治疗。在2018年7月至2023年3月之间，有五名患者访问了我们的机构，在那里他们接受了股直肌钙化性肌腱炎的治疗。所有患者均出现严重急性髋部疼痛。射线照片,计算机断层扫描,磁共振成像，髋关节超声检查显示关节外钙化，提示股直肌钙化性肌腱炎。所有患者均口服200mg西咪替丁和非甾体抗炎药，每天两次。平均2周内达到无痛状态。三名患者的钙沉积消失，两名患者的钙沉积减少。症状没有复发。此外，未观察到钙沉积的复发或增大。它似乎是治疗股直肌钙化性肌腱炎的有效方法；然而，西咪替丁对钙化性肌腱炎的作用机制尚未详细阐明。
