( a) “C” type sigmoid.( b) “S” type sigmoid.( c) Flat face sigmoid.( d) Ski-slope sigmoid. Bony architecture only accounts for approximately 20% of the DRUJ’s stability. 9 The remainder of the stability is afforded by the surrounding soft tissue. These soft tissue restraints include the triangular fibrocartilage complex (TFCC), joint capsule, interosseus .
Distal radioulnar joint (DRUJ) compression test for DRUJ instability. To perform the DRUJ compression test, the examiner compresses the radial and ulnar heads together and then rotates the forearm.

To perform the DRUJ compression test, the examiner compresses the radial and ulnar heads together and then rotates the forearm. Pain with the maneuver suggests DRUJ instability, acute intraarticular injury, or arthritis. Graphic 78662 Version 5.0. A galeazzi fracture is a distal 1/3 radial shaft fracture with an associated distal radioulnar joint (DRUJ) injury. Diagnosis can be suspected with a distal radius fracture with widening of the radioulnar joint on AP wrist radiographs and volar/dorsal subluxation of the radioulnar joint on lateral wrist radiographs.ulnar-sided injuries associated with distal radius fractures. Improper management of distal radioulnar complex injuries may result in limited wrist motion, persistent DRUJ instability, and pain despite successful fracture union. The distal ulna is the keystone of the distal radioulnar articulation. An understanding of the components of the distal radioulnar complex and .

Focused examination includes palpation of the DRUJ, the TFCC (distal to the ulnar head and at the ulnar fovea ), the extensor carpi ulnaris (ECU), and the lunotriquetral joint. Provocative tests include the ulna grind test, the “piano key” test, the lunotriquetral ballottement test, and the pisotriquetral grind test.

To perform the TFCC Compression Test according to Prosser et al. in the year 2011, fixate your patient’s radius and ulna with one hand close to the joint line. Then grab your patient’s hand at the height of the meta-carpals from radial and bring his wrist into ulnar deviation under axial compression. . Distal Radioulnar Joint / DRUJ Test . This article reviews the anatomy and mechanics of pronation and supination (axial rotation) of the forearm through the distal radioulnar joint (DRUJ), and the proximal radioulnar joint (PRUJ). Injuries to the bones and/or ligaments of the forearm, wrist, or elbow can result in instability, pain, and limited rotation. Acute dislocations of the DRUJ commonly occur along .The TFCC compression test is performed by ulnar deviating the forearm in neutral rotation. Reproduction of symptoms indicates that the test is positive In the TFCC stress test an axial load is applied to a ulnar-deviated wrist which produces pain and discomfort. The piano key test is done to assess the stability of the DRUJ. Create Personal Test Create Group Test . (TFCC compression) or radial deviation (TFCC tension) Imaging. Radiographs. . do not extend bone removal into the DRUJ. pros & cons. intrinsic stability of ECU, TFCC, and .
OA of the distal radial ulnar joint (DRUJ) is a common cause of wrist pain in OA and in rheumatoid arthritis (RA). Primary OA of the DRUJ can be associated with positive ulnar variance. . (DRUJ) Compression Test. Distal Radial Ulnar Joint (DRUJ) Stability Test. Extensor Carpi Ulnaris (ECU) Subluxation. Extensor Carpi Ulnaris (ECU) Tenderness . components of the DRUJ also have been characterized. Compression and axial loading across the wrist are primarily transmitted to the distal radius, but the force is partially transmitted through the TFC to the ulnar .

Successful treatment of problems involving the distal radioulnar joint (DRUJ) requires an understanding of the complex bony and ligamentous anatomy. . (TFCC compression test) ( Fig. 71-4 ) will illicit a painful response. A click is frequently present with forearm rotation. Figure 71-4 . Triangular fibrocartilage complex compression test . To assess the clinical outcomes and identify the ideal indication for implementing dorsal distal radioulnar joint (DRUJ) capsular imbrication after triangular fibrocartilage complex (TFCC) repair in cases of DRUJ instability. We conducted a retrospective study on patients who underwent arthroscopic TFCC repair between 2016 and 2021. Inclusion criteria comprised a . The dorsopalmar stress test and Ballottement test were positive (Video 1). X-ray images revealed widening of the right DRUJ and posterior dislocation of the ulnar head (Figure 1). . We do not recommend forceful compression of the DRUJ with clamp. After the procedure was performed, the wrist was immobilized using a forearm brace and set at a . DRUJ instability. Fovea sign.

The piano key sign test is used to assess the stability of the distal radio-ulnar joint (DRUJ). . In the piano key sign test, the wrist is placed into pronation and the hand is stabilised. Observation of the dorsal ulnar prominence relative to radius must be done and then the ulnar head must be pushed in a volar direction.The TFCC transmits 20% of the forearm’s axial load, is the major stabilizer of the distal radioulnar joint (DRUJ), and a stabilizer of the ulnar carpus; 1 thus, . (DRUJ) Compression Test. Distal Radial Ulnar Joint (DRUJ) Stability Test. Extensor Carpi Ulnaris (ECU) Subluxation. Extensor Carpi Ulnaris (ECU) Tenderness. Introduction. Injuries to the extensor carpi ulnaris (ECU), triangular fibrocartilage complex (TFCC), and distal radioulnar joint (DRUJ) are common diagnoses in athletes complaining of ulnar-sided wrist pain [1–8].Sports requiring repeated pronation/supination, radial/ulnar deviation, and axial loading of the forearm and wrist predispose these athletes to .
- ulnar impaction test: pain w/ wrist hyperextension and ulnar deviation with axial compression; - piano key sign: (for instability); - laxity or instability of the R-U joint w/ controled dorsal palmar shucking; - DRUJ is tested w/ forearm in neutral positionDRUJ脱臼・亜脱臼. DRUJ単独脱臼は比較的まれな外傷で、通常は橈骨遠位端骨折やGaleazzi骨折に伴うことが多い疾患です。外観上、背側脱臼の場合には尺骨頭の突出、掌側脱臼の場合には尺骨頭部の陥凹を呈します。 Afterwards the Ballottement test is performed to evaluate DRUJ stability . Ulnar translation of the radial shaft of 3–5 mm seems to be reasonable. The ulnar translation is limited to avoid engagement of the ulnarmost corner of the radial shaft and the ulnar neck. . Primary ulnar impingement is characterized by a positive DRUJ compression .
