Distal Radioulnar Joint injuries: Surgical anatomy, physical examination, Imaging and principles of management
Journal Title: Journal of Karnataka Orthopaedic Association - Year 2019, Vol 0, Issue 0
Abstract
The complex anatomy of distal radioulnar can make diagnosis of this joint problems challenging. Disorders of the DRUJ are a major source of ulnar-sided wrist pain. Stabilization of this joint is provided by both intrinsic and extrinsic stabilizers and the joint capsule. Several clinical tests have been suggested to determine static or dynamic DRUJ stability. Radiologic evaluation of DRUJ instability begins with conventional radiographs .CT-scan seems to be the best additional modality to evaluate the osseous structures. MRI has proven to be more sensitive and specific for TFCC tears, potentially causing DRUJ instability, while arthroscopy is the gold standard for evaluation. Symptomatic DRUJ injuries treatment can be conservative or operative. Operative treatment consist of restoration of osseous and ligamentous anatomy. Chronic instability requires reconstruction of the stabilizing ligaments to avoid onset of arthritis. Salvage procedures in arthritis is gaining acceptance in the management of arthritis. This review covers various problems affecting the distal radioulnar joint, including fractures and dislocations, triangular fibrocartilage pathology and arthritis.
