Fractures in the proximal third have a high incidence of AVN (~30%) Waist fractures in the middle third is the most frequent fracture site and has moderate risk of AVN. Fractures in the distal third are rarely complicated by AVN. Non union can also occur from undiagnosed or undertreated scaphoid fractures. Arterial flow to the scaphoid enters ...
Fractures of the fingers occur when the finger or hands hit a solid object. Fractures are most common at the base of the little finger (boxer's fracture). Nerve injuries occur as a result of trauma, compression or over-stretching. Nerves send impulses to the brain about sensation and also play an important role in finger movement.
A jammed finger (a trauma from a blow on the end of the finger) is often caused by trying to catch a ball and may break the finger. Misusing tools, especially power tools, [2] can also break fingers. [2] Occasionally, an infection or tumour can cause a broken finger; [1] this is called a pathological fracture.
Cracked tooth syndrome could be considered a type of dental trauma and also one of the possible causes of dental pain.One definition of cracked tooth syndrome is "a fracture plane of unknown depth and direction passing through tooth structure that, if not already involving, may progress to communicate with the pulp and/or periodontal ligament."
[1] [2] If sharp pain occurs along the distal radius (top of the forearm, about an inch below the wrist), de Quervain syndrome is likely. While a positive Finkelstein test is often considered pathognomonic for de Quervain syndrome, the maneuver can also cause some pain in those with osteoarthritis at the base of the thumb. [2]
Gamekeeper's thumb and skier's thumb are two similar conditions, both of which involve insufficiency of the ulnar collateral ligament (UCL) of the thumb. The chief difference between these two conditions is that skier's thumb is generally considered to be an acute condition acquired after a fall or similar abduction injury to the metacarpophalangeal (MCP) joint of the thumb, whereas gamekeeper ...
Cheiralgia paraesthetica (Wartenberg's syndrome) is a neuropathy of the hand generally caused by compression or trauma to the superficial branch of the radial nerve. [1] [2] The area affected is typically on the back or side of the hand at the base of the thumb, near the anatomical snuffbox, but may extend up the back of the thumb and index finger and across the back of the hand.
A tooth that has experienced trauma may become loose due to the periodontal ligament becoming damaged or fracture to the root of the tooth. Splinting ensures that the tooth is held in the correct position within the socket, ensuring that no further trauma occurs to enable healing. [37] A splint can either be flexible or rigid.
