Dislocation - Fracture or avulsion or bony defect Factor
Fracture: The RMA defines "fracture" to mean an acquired break or rupture in a bone.
Avulsion: Generally refers to a tearing away (or pulling off) such as with a traumatic amputation.
An avulsion fracture is a bone fracture which occurs when a fragment of bone tears away from the main mass of bone as a result of physical trauma. This can occur at the ligament due to the application forces external to the body (such as a fall or pull) or at the tendon due to a muscular contraction that is stronger than the forces holding the bone together. This type of fracture is more prevalent in highly trained athletes.
If the fracture is small, it is usually sufficient to treat with ice, rest and support bandage, but in more severe cases surgery and fixation or pinning may be required.
Bony defect: Is any abnormality to the bone, but is usually represented by additional or missing bone structure. It can be caused by congenital malformations, such as with a cleft palate, or due to joints not healing properly or not being aligned properly following fracture or from surgical procedures such as a hip replacement, or knee reconstruction.
General Information
For a fracture, or avulsion, or bony defect to contribute to dislocation or joint instability, it must have involved (at least one of) the articulating surfaces of the affected joint.

Preliminary questions [42230]
42233 there is some evidence that a fracture or avulsion or bony defect involving the articulating surfaces may be a factor in the development of dislocation.
42124 the veteran had a fracture or avulsion or bony defect involving the articulating surfaces at side and site of the body at some time.
42125 the veteran had the fracture or avulsion or bony defect involving the articulating surfaces to side and site of the body due to an illness or injury which is identifiable.
42234 as a consequence of the identified illness or injury, the veteran had the fracture or avulsion or bony defect involving the articulating surfaces, to side and site of the body, at the time of the clinical onset of dislocation.
42235 the veteran has established the causal connection between the fracture or avulsion or bony defect involving the articulating surfaces and VEA service for the clinical onset of dislocation.
42236 the veteran has established the causal connection between the fracture or avulsion or bony defect involving the articulating surfaces and operational service for the clinical onset of dislocation.

42237 the veteran has established the causal connection between the fracture or avulsion or bony defect involving the articulating surfaces and eligible service for the clinical onset of dislocation.
Clinical onset and operational service [42236]
42135 the identified illness or injury, which caused the fracture or avulsion or bony defect involving the articulating surfaces affecting side and site of the body, is causally related to operational service.
Clinical onset and eligible service [42237]
42136 the identified illness or injury, which caused the fracture or avulsion or bony defect involving the articulating surfaces affecting side and site of the body, is causally related to eligible service.
