  • [ 1 ] This refers to the shape of the bone, supposedly reminiscent of a boat, and in older literature on human anatomy [ 2 ] the scaphoid is referred to as the navicular bone of the hand, since there is also a bone in a similar position in the foot, called the navicular. (en-academic.com)
  • Along with the proximal and distal radioulnar articulations, an interosseous membrane originates medially along the length of the body of the radius to attach the radius to the ulna. (wikipedia.org)
  • With the palm bearing the weight, there is the risk of forearm bone (distal radius) fracture too. (targetwoman.com)
  • The most common sites of fracture in the wrist are at the radius (the large forearm bone) and the scaphoid (one of the small hand bones). (scosortho.com)
  • Fractures of the scaphoid must be recognized and treated quickly, as prompt treatment by immobilization or surgical fixation increases the likelihood of healing in anatomic alignment avoiding mal union or non union. (en-academic.com)
  • This study aimed to analyze the clinical and radiological results of patients who underwent scaphoid fixation with pedicled VBG due to non-union of a scaphoid fracture. (handmicrosurgeryjournal.com)
  • Methods: The patients who were operated due to scaphoid non-union and underwent fixation with pedicled VBG between 2017 and 2018 were reviewed retrospectively. (handmicrosurgeryjournal.com)
  • If the fractured ends of the bone are not displaced, external fixation by application of a cast or splint may be enough to treat the wrist fracture. (scosortho.com)
  • Another option is open reduction and external fixation, which involves stabilizing the fracture from the outside by means of a metal frame, which is attached to surgical pins that pass through the skin to the fractured ends of the bone. (scosortho.com)
  • These are often treated with just a cast or splint, although occasionally if there are multiple broken bones or the bones have moved significantly, a surgery may be required. (drnagarkar.com)
  • In many cases, the broken bones can be set into good position if it has not been too long after your injury - but a long delay can increase the likelihood of needing surgery. (drnagarkar.com)
