A Study on the Diagnostic Value of Dual-Energy CT (DECT) Imaging in Patients With Gouty Arthritis.

Objectives: To explore the diagnostic value of dual-energy computed tomography (DECT) in patients with gouty arthritis.

Methods: A total of 160 patients with gouty arthritis who were treated in our hospital from January 2023 to October 2023 were selected as the research subjects. The participants were randomly divided into two groups: an observation group and a control group.

A Novel Technique of Arthroscopic-Assisted Four-Corner Fusion and Robot-Assisted Fixation for Scaphoid Nonunion Advanced Collapse Wrist: A Single Case Study.

Objective: Scaphoid nonunion advanced collapse (SNAC) is a relatively common and debilitating wrist disorder yet its treatment remains challenging and controversial. We aim to describe a novel technique of a dual arthroscopic and robotic assisted four-corner fusion (4CF) in the treatment of SNAC wrist.

Methods: In this study, we describe an original arthroscopic and robotic assisted 4CF, which is novel and currently unpublished in literature.

Locally Invasive Pigmented Villonodular Synovitis of the Wrist Treated by Arthroscopic Resection and Bone Grafting.

Pigmented villonodular synovitis (PVNS) is a benign but locally aggressive neoplasm that can affect tendon sheath, bursae, or joint. The wrist joint however is uncommonly involved and here we present a case of chronic monoarticular joint pain and swelling in a healthcare professional that was later histologically verified to be PVNS of the radiocarpal joint. The patient had a magnetic resonance imaging (MRI) performed prior to surgery which showed a locally invasive bony tumor of the scaphoid.
