Ulnar styloid impaction syndrome (USIS) is produced by the tip of an oversized ulnar styloid inappropriately contacting the triquetrum. This condition results in chondromalacia, synovitis, and ulnar-sided wrist pain. We report a rare case of bilateral USIS that presented with a prolonged course. The patient's symptoms resolved in both wrists following two separate ulnar styloidectomy procedures. Our case differs from previous reports in that it involves a patient whose own history of USIS led to a timelier diagnosis of the same disease in the contralateral wrist. To the best of our knowledge, there are no prior reports of bilateral USIS. USIS remains an uncommon cause of ulnar-sided wrist pain and a particularly difficult diagnosis to confirm. Here, we illustrate that this syndrome can be confidently approached using a combination of careful attention to patient history, physical examination, and various imaging methods.
尺骨茎突撞击综合征（USIS）是由过大的尺骨茎突尖端不恰当地接触三角骨引起的。这种情况会导致软骨软化、滑膜炎和尺侧腕部疼痛。 我们报告一例罕见的双侧USIS病例，病程较长。在进行了两次单独的尺骨茎突切除术之后，患者双腕的症状均得到缓解。 我们的病例与之前的报告不同之处在于，该患者自身的USIS病史导致对侧手腕同一疾病的诊断更加及时。据我们所知，此前尚无双侧USIS的报告。 USIS仍然是尺侧腕部疼痛的罕见原因，也是一种特别难以确诊的疾病。在此，我们说明，通过仔细关注患者病史、体格检查和各种影像学方法相结合，可以可靠地诊断这种综合征。
