Clinical and non-clinical aspects of distal radioulnar joint instability.

Wijffels M, Brink P, Schipper I - Open Orthop J (2012)

Bottom Line: MRI has proven to be more sensitive and specific for TFCC tears, potentially causing DRUJ instability.Symptomatic DRUJ injuries treatment can be conservative or operative.If not successful, salvage procedures can be performed to regain stability.

ABSTRACT
Untreated distal radioulnar joint (DRUJ) injuries can give rise to long lasting complaints. Although common, diagnosis and treatment of DRUJ injuries remains a challenge. The articulating anatomy of the distal radius and ulna, among others, enables an extensive range of forearm pronosupination movements. Stabilization of this joint is provided by both intrinsic and extrinsic stabilizers and the joint capsule. These structures transmit the load and prevent the DRUJ from luxation during movement. Several clinical tests have been suggested to determine static or dynamic DRUJ stability, but their predictive value is unclear. Radiologic evaluation of DRUJ instability begins with conventional radiographs in anterioposterior and true lateral view. If not conclusive, 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. DRUJ instability may remain asymptomatic. Symptomatic DRUJ injuries treatment can be conservative or operative. Operative treatment should consist of restoration of osseous and ligamenteous anatomy. If not successful, salvage procedures can be performed to regain stability.

Mentions: The musculus extensor carpi ulnaris (ECU) is located on the dorso-medial side of the forearm. The ECU tendon inserts at the base of the 5th metacarpal and transverses the ulnocarpal joint through a fibro-osseous tunnel (sixth dorsal compartment), attached to the ulnar head [3] (Fig. 2).
