While PT pathology remains the differential for ulnar-sided wrist pain, it can often be difficult to diagnose, as symptoms can be variable and radiographic imaging may be negative for any findings.<\/jats:p><jats:p>\n          Case Description\u2003A 24-year-old major league baseball player presented with pain and locking of his wrist during follow through of his bat swing. Plain radiographic imaging, as well as computed tomography (CT) imaging, was negative for any pathology. Dynamic magnetic resonance imaging (MRI) demonstrated a loose body which entered the PT joint when the wrist was moved into a flexed position. This caused entrapment of the loose body and locking of the wrist.<\/jats:p><jats:p>\n          Literature Review\u2003A total of 17 reported patients in the literature have been diagnosed with a PT loose body. The clinical examination findings, radiographic findings, and surgical findings are reviewed.<\/jats:p><jats:p>\n          Case Relevance\u2003PT loose bodies can present a challenging clinical picture to diagnose. The purpose of this case report is to review the appropriate clinical workup, including common examination findings and advanced imaging techniques, to help the clinician with the diagnosis.<\/jats:p>","DOI":"10.1055\/s-0040-1710394","type":"journal-article","created":{"date-parts":[[2020,5,15]],"date-time":"2020-05-15T22:57:15Z","timestamp":1589583435000},"page":"518-522","source":"Crossref","is-referenced-by-count":3,"title":["Locked Wrist: A Case Report and Literature Review on Pisotriquetral Loose Bodies"],"prefix":"10.1055","volume":"9","author":[{"given":"R.
