Statements of Principles

Dislocation - Biomechanical abnormality Factor

In the Statements of Principles for joint instability and dislocation the RMA defines "a biomechanical abnormality involving the affected joint" to mean an abnormality of the forces acting on the affected joint as a result of a muscle, tendon, ligament, or bone, that maintains the normal structural or functional relationship between the articulating surfaces of the affected joint, and that is not functioning correctly, is abnormal or is misaligned. This definition includes biomechanical abnormality as a result of surgery involving the stabilising structures of the affected joint and extra-articular malunion of a fracture of a bone involved in the affected joint.

General Information

This type of abnormality can result from injury or disease.  For the abnormality to contribute to dislocation or joint instability, it must involve the same joint as the joint affected by the dislocation, or joint instability.

You may need to seek medical advice to establish if any contended condition meets the requirements of the definition.

Preliminary questions [42231]

42238 there is some evidence that a biomechanical abnormality involving the affected joint may be a factor in the development of dislocation.

42141 the veteran had a biomechanical abnormality as defined in the Statement of Principles.

42239 the veteran had a biomechanical abnormality to side and site of the body at some time.

42240 the veteran had the biomechanical abnormality to side and site of the body due to an illness or injury which is identifiable.

42241 as a consequence of the identified illness or injury, the veteran had the biomechanical abnormality, to side and site of the body, at the time of the clinical onset of dislocation.

42242  the veteran has established the causal connection between the biomechanical abnormality and VEA service for the clinical onset of dislocation.

42243   the veteran has established the causal connection between the biomechanical abnormality and operational service for the clinical onset of dislocation.

or

42244   the veteran has established the causal connection between the biomechanical abnormality and eligible service for the clinical onset of dislocation.

Clinical onset and operational service [42243]

42245  the identified illness or injury, which caused the biomechanical abnormality affecting side and site of the body, is causally related to operational service.

Clinical onset and eligible service [42244]

42246  the identified illness or injury, which caused the biomechanical abnormality affecting side and site of the body, is causally related to eligible service.
