Distal radioulnar articulation

Triangular Fibrocartilage Complex (TFCC) is located on the ulnar side of the wrist. According to Barlow (2016), the TFCC contains an articular disc and three ligaments which attach to carpal bones, the ulna, and radius (p. 271). Blazar stated the three ligaments include the dorsal radio-ulnar ligament, the ulnar collateral ligament, and the ulno-carpal ligament (p. 60). The TFCC is a shock absorber, allows for wrist stability, grip, and weight bearing and rotational loading tasks. Neumann, Kirkendall, and Moorman (2016) stated the TFCC is the main stabilizer of the distal radioulnar joint and allows for ulnocarpal stability (p. 181). Following an injury to the TFCC, stabilization would be impacted. An injury to the TFCC is commonly caused…

capillary network which receives blood from the renal artery. § The lighter, inner region is called the medulla. Each nephron extends across the medulla to form structures called renal pyramids. § The renal pyramids project into a central space called the pelvis Urine passes out into the pelvis before it passes down the ureter. The nephron is the functional unit of the kidney. At one end of the nephron is the cup-shaped Bowman's capsule. Immediately below the …

This type of fracture involves an isolated fracture of the junction of the mid to distal radius with associated dislocation of the distal radiolunar joint which is often difficult to recognize. When there is presentation of a radial only fracture the radioulnar joint should be examined carefully on the x-ray (Gaillard, F., radiopaedia.org). According to Putigna & Ursone (emedicine.com) a relatively uncommon injury accounting for fewer than 5% of all forearm fractures is the Monteggia fracture.…
