![]() Volar lunate facet fractures of the distal radius. Volar marginal rim fractures of the distal radius have a higher rate of associated carpal injuries. Ligament origins are preserved in distal radial intraarticular two-part fractures. 1 Distal radius fractures in older patients are often initially treated with closed reduction and cast immobilization. Fractures happen when a force is applied to a bone that is greater than the strength of the bone. Occasionally a small chip or fracture can occur in the ulna. In medical terms this is called a distal radius fracture. The incidence of distal radius fractures involves all age groups the pediatric and elderly populations are at the greatest risk for sustaining this injury. distal Radius fracture surgery medical shortvideo ortho surgery. What is a distal radius fracture A wrist fracture is a break in the radius bone, close to the wrist joint. It accounts for 25 to 50 of all broken bones and is most commonly seen in older females and young. Fractures of the distal radius are one of the most common types of injuries encountered by hand surgeons. Ligament contribution to patterns of articular fractures of the distal radius. A broken wrist or distal radius fracture is an extremely common type of fracture. Anatomical and clinical concepts in volar ulnar corner fractures. The associated ligament injury is a sleeper lesion, which can be unmasked with time or loading (1).ġ. Long radiolunate ligament avulsion from the scaphoid facet represents an injury within the osteoligamentous unit. Volar rim fractures are associated with carpal instabilities, failure of fixation, and reoperation (4, 5). ![]() The osteoligamentous unit concept should underpin the strategies for reduction, exposure, and stabilization of distal radius injuries (1). We postulate that ligamentous attachments are critical to fracture development, remain attached at presentation and throughout treatment, unless the surgeon divides the ligament (2). The 3 common fragments include the following: volar ulnar corner (VUC), dorsal ulnar corner (DUC), and radial styloid (2). During this video, the author discusses functional anatomy, including the Watershed ridge, critical corner, and radial calcar (1).ĭistal radius fractures do not occur randomly, but commonly occur between the ligament attachments, creating osteoligamentous units - fragment and associated ligament (2, 3). Understanding wrist functional anatomy and pathoanatomy of distal radius injuries is critical in creating a reliable treatment algorithm (1).
