Distal radioulnar joint instability in distal radius fractures: The role of sigmoid notch and triangular fibrocartilage complex revisited

Clinical Comparison of Arthroscopic Versus Open Repair of Triangular Fibrocartilage Complex Tears

“…Anatomic studies by Haugstvedt et al 17 and Cole et al 18 reported that TFCC pathology may lead to DRUJ instability. Furthermore, disruption of the insertion of the TFCC into the foveal region can lead not only to symptomatic DRUJ instability but also to clinically evident subluxation of the distal ulna.…”

Clinical and Radiographic Factors Associated With Distal Radioulnar Joint Instability in Distal Radius Fractures

“…The stability of the DRUJ in the injured wrist was assessed by comparison with the normal wrist because the amount of joint relaxation varies among individuals [10], and was categorized as no instability, moderate instability (increased translation of the DRUJ with firm end), or severe instability (increased translation without firm end). Because the dorsoulnar fragments might be a cause of DRUJ instability without a triangular fibrocartilage complex injury [6], we fixed them with one or two K-wires (1.4 mm) under arthroscopic guidance. Surgical exploration of the DRUJ and repair of the deep triangular fibrocartilage complex was performed for patients with moderate or severe DRUJ instability.…”

Reconstruction of the Distal Ulna: Instability, Impaction, Impingement, and Arthrosis

“…In a simulation of high-energy fractures, lunate facet injuries produced DRUJ instability, However, TFC injuries in addition to facet fractures produced greater instability. 10 Instability may occur as a result of residual malalignment, which may affect bony congruency as well as the soft tissue stabilizers of the joint. Corrective osteotomy alone may not be sufficient for joint stabilization.…”
