• heal
  • The scaphoid can be slow to heal because of the limited circulation to the bone. (wikipedia.org)
  • There is zero chance that the bone has had time to heal around the screw sufficiently for stability. (mgoblog.com)
  • A bone that fails to heal is called a nonunion . (mgoblog.com)
  • But either way it's a tough break to see on an x-ray unless they are specifically looking at the scaphoid, and it's also typically a pain in the ass to heal properly with no after effects. (fiveouncesofpain.com)
  • dorsal surface of the bone
  • The dorsal surface of the bone is narrow, with a groove running the length of the bone and allowing ligaments to attach, and the surface facing the fingers (anatomically inferior) is smooth and convex, also triangular, and divided into two parts by a slight ridge. (wikipedia.org)
  • tenderness
  • Therefore, people with tenderness over the scaphoid (those who exhibit pain to pressure in the anatomic snuff box ) are often splinted in a thumb spica for 7-10 days at which point a second set of X-rays is taken. (wikipedia.org)
  • SLAC: Tenderness 1 cm above Lister's Tubercle Tests: Watson's test Finger extension test SNAC: Tenderness at the anatomical snuff box Painful pronation and supination when performed against resistance Pain during axial pressure Osteoarthritis between the radius bone and the carpals is indicated by a radiocarpal joint space of less than 2mm. (wikipedia.org)
  • articulation
  • In reptiles, birds, and amphibians, this bone is instead commonly referred to as the radiale because of its articulation with the radius. (wikipedia.org)
  • The inferior surface is oval, concave from side to side, convex from before backward, so as to form a saddle-shaped surface for articulation with the base of the first metacarpal bone. (wikipedia.org)
  • The inferior surface is divided by two ridges into three facets, for articulation with the second, third, and fourth metacarpal bones, that for the third being the largest. (wikipedia.org)
  • it is bounded superiorly by a smooth, convex surface, for articulation with the scaphoid bone. (wikipedia.org)
  • scintigraphy
  • Magnetic resonance imaging or bone scintigraphy may be useful if the diagnosis remains unclear after an initial period of immobilization. (aafp.org)
  • thumb
  • I broke my thumb bone at the bottom they said it was a clean break on the 25 of this month. (healthtap.com)
  • UFC heavyweight contender Brandon "The Truth" Vera will be out of action until at least May after breaking a bone in his thumb during his UFC 77 fight with Tim Sylvia, MMAWeekly is reporting . (fiveouncesofpain.com)
  • It is situated at the radial side of the carpus, between the scaphoid and the first metacarpal bone (the metacarpal bone of the thumb). (wikipedia.org)
  • The trapezium is found within the distal row of carpal bones, and is directly adjacent to the metacarpal bone of the thumb. (wikipedia.org)
  • The trapezium is susceptible to arthritis at the joint with the metacarpal bone of the thumb, due to overuse. (wikipedia.org)
  • It has 27 bones, not including the sesamoid bone, the number of which varies between people, 14 of which are the phalanges (proximal, intermediate and distal) of the fingers and thumb. (wikipedia.org)
  • fixation
  • Treatment is often open reduction and internal fixation, which is surgical realignment of the bone fragments and fixation with pins, screws, or plates. (wikipedia.org)
  • collapse
  • While use of vascularized bone grafts is not new, recent advances have improved the outcomes as they address both avascularity and carpal collapse. (mayoclinic.org)
