Assessment of Distal Radioulnar Joint Instability After Distal Radius Fracture: Comparison of Computed Tomography and Clinical Examination Results

Distal Radioulnar Joint Stress Radiography for Detecting Radioulnar Ligament Injury

“…11 In addition, DRUJ instability assessed using dynamic CT is not always correlated with the degree of instability measured by manual stress tests. 12 Precise criteria for evaluating DRUJ instability are still not standardized.…”

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

“…The clinical assessment methods we used also were used in multiple previous studies [8,16,26,36,42]. Furthermore, physical evaluation methods correlate with intraoperative findings better than CT and show higher interobserver reliability in the assessment of DRUJ instability [8,16,36,42]. Second, we could not use more advanced statistical methods like logistic regression analysis because the number of observations available as a dependent variable was insufficient.…”

“…Before gowning, the contralateral normal DRUJ was examined by the surgeon (BCK) as the normal reference for the injured wrist. With the patient's elbow in 90°fl exion and forearm in neutral rotation, the surgeon firmly grabbed the distal end of the radius with one hand and tried to passively translate the distal ulna in the dorsal and volar directions with the other hand [16]. The same stress test was repeated with the patient's forearm in supination and pronation.…”

Capsular Imbrication for Posttraumatic Instability of the Distal Radioulnar Joint

“…The examiner firmly grasped the radius with 1 hand while holding the ulnar head with the other, and applied anteroposterior force. 22 Depending on the symptoms experienced by the patient and the difference in translation compared with the opposite wrist, we classified test results into 1 of 4 grades ( Table 1). 23 Surgical reconstruction was indicated in patients with grade 2 and 3 instability.…”
