Arthroscopic resection of pisotriquetral joint loose body: a case report

Arthroscopic Pisiform Excision in Pisotriquetral Osteoarthritis Technique Using a Direct Pisotriquetral Portal

Pisotriquetral (PT) joint arthritis is a common cause of ulnar-sided wrist pain. Open pisiform excision is a well-established procedure and is indicated when the conservative treatment fails. Although arthroscopic visualization of the PT joint is part of the routine examination in a patient with ulnar-sided wrist pain, therapeutic arthroscopy of the PT joint is limited to one case in the literature through the standard dorsal portals. Arthroscopic pisiform excision is a novel technique described by the authors. The first aim of this procedure is pain relief maintaining wrist stability and strength. With this minimally invasive approach we believe that preserving the flexor carpi ulnaris and the PT ligament complex we maintain their biomechanical function, while at the same time, reducing scar tenderness and postoperative discomfort with better esthetic results and less recovery time. In addition to standard dorsal portals, a direct PT portal was used to have access to the PT space and as a working portal to complete the pisiform excision.

Locked Wrist: A Case Report and Literature Review on Pisotriquetral Loose Bodies

Background  Pisotriquetral (PT) loose bodies have been described in the literature only a few times as case reports. 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. Case Description  A 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. Literature Review  A 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. Case Relevance  PT 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.

Advances in hand and wrist arthroscopy

Hand and wrist arthroscopy has gained popularity over the past few decades. Arthroscopy is a valuable diagnostic tool in cases where clinical and radiographic findings do not show a clear picture of the patient's pathologic condition. Arthroscopy also allows care providers to perform therapeutic interventions in a less invasive manner than would have been possible with a standard open approach. Over the past three decades, there have been substantial advances in the techniques and outcomes in hand and wrist arthroscopy. With this article, the authors aim to introduce the application of newer arthroscopic techniques in the hand and wrist that may be of diagnostic and/or therapeutic value.

Pisotriquetral joint disorders: an under-recognized cause of ulnar side wrist pain

Pisotriquetral joint disorders are often under-recognized in routine clinical practice. They nevertheless represent a significant cause of ulnar side wrist pain. The aim of this article is to present the main disorders of this joint and discuss the different imaging modalities that can be useful for its assessment.

Bilateral pisotriquetral loose bodies

Case reports detailing diagnosis and effective treatment of pisotriquetral loose bodies are scarce. This article describes an even rarer case of bilateral pisotriquetral joint loose bodies, explores the relative diagnostic roles of magnetic resonance imaging versus computed tomography, and outlines effective strategies used for the management of this condition drawn from the literature and our own experience.
