• medial
  • The medial surface has two facets, a flattened semi-lunar facet articulating with the lunate bone, and an inferior concave facet, articulating alongside the lunate with the head of the capitate bone. (wikipedia.org)
  • In particular, free vascularized bone graft taken from the medial femoral condyle demonstrates significant promise in addressing complex scaphoid nonunions. (mayoclinic.org)
  • To date, Mayo Clinic orthopedic hand specialists have performed nearly 70 free medial femoral condyle vascularized bone grafts for difficult scaphoid nonunions with avascular necrosis. (mayoclinic.org)
  • The procedure is a complex microvascular surgical technique that utilizes two microvascular-trained hand surgeons, with an average surgical time of 2.5 hours," explains Mayo hand and microvascular surgeon, Alexander Y. Shin, M.D. "One team harvests the medial femoral condyle graft, while the other prepares the scaphoid and the recipient vessels, and in this way a promising new technique can effectively manage a complex and difficult problem.

  • heal
  • The scaphoid bone is the most commonly broken bone in the wrist and is difficult to heal because of limited circulation, or blood flow. (wisegeek.com)
  • 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)
  • Within the context of a prospective randomized study we examined the hypothesis that 80% of such fractures would heal in less than ¶8 weeks when low-intensity ultrasound was applied, while without ultrasound only 20% of scaphoid fractures would heal within ¶8 weeks. (springer.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
  • Anatomic snuffbox tenderness and scaphoid tubercle tenderness are sensitive but not specific tests for scaphoid fractures. (aafp.org)
  • People with scaphoid fractures generally have snuff box tenderness. (wikipedia.org)
  • 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)
  • thumb
  • The scaphoid bone lies on the thumb side of the wrist, connecting with the radius on the proximal side. (wisegeek.com)
  • You typically break the end of your radius (the bone between your elbow and your thumb) in one of two patterns called colle's and smith's fractures. (healthtap.com)
  • 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)
  • In the first round of his fight with Sylvia, Vera broke his left scaphoid, a small bone in the thumb that that keeps it from bending too far back towards the wrist, and continued the fight using just his right hand. (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)
  • 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)
  • 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)
  • Bone scintigraphy is a cost-effective and specific test in assessing for occult scaphoid fractures. (aafp.org)
  • anatomic
  • Fractures of the scaphoid must be recognized and treated quickly, as prompt treatment by immobilization or surgical fixation increases the likelihood of the bone healing in anatomic alignment, thus avoiding mal-union or non-union. (wikipedia.org)
  • The scaphoid is located below the anatomic snuffbox. (aafp.org)
  • screw
  • He has a SCREW in his BONE! (mgoblog.com)
  • hey mr wine taster with a screw in the wrist, i also got a screw put into my scaphoid bone recently, i would love to talk with you of the effects on healing the wrist and drinking alcohol, please email me i have some questions, is it really that important to stay away from alcohol with our problem? (winetastingguy.com)
  • He is known for his work with the scaphoid bone and related invention, the Herbert screw. (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)
