Isolated synovial chondromatosis of the ankle: A case report.
Int J Surg Case Rep
October 2023
Tunis Manar university, Tunisia.
Introduction And Importance: At the age of 20, young adults are most susceptible to synovial chondromatosis, a rare condition characterized by the metaplasia of the synovial membrane into cartilaginous or osteocartilaginous tissue. Synovial chondromatosis is exceptionally uncommon in the ankle.
Case Presentation: An orthopedist evaluated a 26-year-old man with a history of recurring ankle trauma over a period of 6 months, swelling and pain.

The classification systems of hallux rigidus, including the Coughlin and Shurnas, Hattrup and Johnson, Regnauld, and Roukis classifications, allow for a comprehensive understanding of the condition's severity and aid in informed treatment decisions. The common techniques of radiological imaging, such as standard plain film radiographs, MRI, magnetic resonance arthrography computed tomography (CT), weightbearing CT, and ultrasound, which enable accurate assessment of joint degeneration and associated pathologies for optimal patient care, are reviewed.

Direct MR arthrography (dMRA) is a fundamental technique in diagnosing pathology in major peripheral joints, allowing for precise evaluation of intra-articular structures. Although injection guidance is typically performed using imaging techniques such as ultrasound or fluoroscopy, puncture via anatomical landmarks may be useful in certain circumstances where it has been proven to be a safe and effective procedure. This paper describes the indications and injection technique of dMRA, joint by joint, focusing on the different technical details, from the most common locations, like the shoulder or hip, to those with more restricted clinical indications, such as the wrist, knee, elbow, or ankle.

Department of Radiology, Seoul National University Hospital, Seoul, Republic of Korea; Department of Radiology, Seoul National University College of Medicine, Seoul, Republic of Korea. Electronic address:
Aim: To compare the image quality of virtual noncontrast (VNC) and true noncontrast (TNC) CT images and to evaluate the clinical feasibility of VNC CT images for assessing osteochondral lesions of the talus (OLTs).
Materials And Methods: Forty-five OLT patients who underwent ankle CT arthrography (CTA) using dual-layer spectral detector CT were enrolled. Reconstruction of VNC and three-dimensional volume rendering images was performed.
Ankle, knee, and elbow arthrography: 2022 survey of Society of Skeletal Radiology members.

Department of Radiology, Mayo Clinic Arizona, Phoenix, AZ, USA.
Objective: To determine the preferred ankle, knee, and elbow arthrography injection techniques for Society of Skeletal Radiology (SSR) members and whether more recently described techniques are gaining acceptance. We also sought to determine whether the concept of knowledge translation might explain differences between the preferred technique, year of fellowship graduation, and year the newer technique was described.
Materials And Methods: A 29-question survey was created in Qualtrics and submitted to current SSR members to determine if they perform knee, elbow, and ankle arthrography, and if so, the year of fellowship completion and preferred approaches.
