The AO Foundation/Orthopaedic Trauma Association (AO/OTA) classification generates language-neutral numeric codes for describing broken fingers. They run 78[meaning a fracture of the phalanges of the hand].[number-code of the finger, with thumb=1 and the little finger=5].[number-code of phalanx, counting 1 to 3 outwards from the hand].[number ...
Prognosis for these fractures is generally good, with total healing time not exceeding 12 weeks. The first two weeks will show significantly reduced overall swelling, with improvement in clenching ability showing up first. Ability to extend the fingers in all directions appears to improve more slowly.
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.
Bone healing, or fracture healing, is a proliferative physiological process in which the body facilitates the repair of a bone fracture. Generally, bone fracture treatment consists of a doctor reducing (pushing) displaced bones back into place via relocation with or without anaesthetic, stabilizing their position to aid union, and then waiting ...
In the most minor cases of Bennett fracture, there may be only small avulsion fractures, relatively little joint instability, and minimal subluxation of the CMC joint (less than 1 mm). In such cases, closed reduction followed by immobilization in a thumb spica cast and serial radiography may be all that is required for effective treatment. [5]
Since bone healing is a natural process that will occur most often, fracture treatment aims to ensure the best possible function of the injured part after healing. Bone fractures typically are treated by restoring the fractured pieces of bone to their natural positions (if necessary), and maintaining those positions while the bone heals.
The injured finger may be examined to determine where the pain is worst. [3] If the finger is sprained or dislocated, pain will be worse at the joint rather than the bone. [3] Due to the risk of dislocations or fractures, X-rays should be conducted prior to testing joint stability. This allows for prior detection of a dislocation or fracture. [3]
In terms of anatomy location, fractures of finger phalanges are the most common one at the rate of 14 per 100,000 people per year in the general population, followed by fracture of tibia at 3.4 per 100,000 population per year, and distal radius fracture at 2.4 per 100,000 population per year. [5]
