Hand Fracture Surgery

The hand is very susceptible to injury; from direct blows to twisting injuries to torqueing injuries, or falling on an outstretched hand. Distal, middle, and proximal phalanges are the bones of the fingers, and very susceptible to injury. Boxer’s fracture is when the fifth metacarpal breaks at the head of the bone, usually from striking a stationary object, such as an opponent’s head. The broken head of the bone then sinks down in a palmward direction with pressure from the bones and tendons, causing the knuckle to sink as well. Tuft fracture is when the very tip of the distal phalanx breaks off, wither from trauma or a crush injury. These can pierce the skin and must be dealt with right away. Oblique fractures of the proximal phalanx are slanted, hence the name, and can be displaced badly by tendon force and require setting. Transverse fractures are when the bone is broken in half along a straight axis, and is also susceptible to being pulled out of place by the structures of the hand. All of these represent displaced fractures that typically require surgical intervention to fix. Fingers should all move in alignment, but with a fracture, the position of the bone changes and so they don’t bend the way they should, making a clear sign to doctors that there is a break. Underlapping or overlapping fingers are a common indicator of this. Tuft fractures of the fingertip are fixed using a strong metal wire through the tip and into the part of the finger that it broke off from, holding it in place and allowing for healing. In more serious fractures, especially oblique fractures, it is necessary to open the fingers and put screws in the bone to hold it in place for healing. The risk with this is that scarring can occur and recovery time is lengthened. After most hand or finger fractures, a four to six week period of bracing and immobilization is required to allow for bone healing, followed by a minor surgery to remove any hardware that was used to hold the bones in place. Following this, two to three months of therapy will be required to return full range of motion and function to the injured hand.
