Joint instability - Laxity of the joint capsule or stabilising ligament Factor

The factor applies in both joint instability and dislocation SOPs.

  • Joint capsule laxity:  The joint capsule is an envelope surrounding a synovial joint, such as in the wrists, shoulders, elbows, hips, knees, ankles, thumb and spine.  Laxity can occur from trauma, activity or from a disease process.
  • Ligamentous laxity:  Ligaments are elastic bands of tissue that attach to the bones and form a joint.  Ligaments provide stability and strength to the joint by restricting movement and holding the bones in place, and thereby facilitate bending, jumping and stretching.  Lax ligaments require strapping or taping to improve proprioception properties (the awareness of the movement and position of the body and body parts) and reduce the likelihood of further damage to the affected ligaments and joints.  Some cases require surgery if the laxity results in repeated dislocation of the joint.

A history of the activity or disease process that caused the laxity should have been noted by the medical officer managing the person's dislocation or joint instability.  However, if the information is unclear, or the relevant medical records cannot be obtained, you will need to seek medical advice to establish if the laxity was present prior to the clinical onset (or clinical worsening) of the condition.

Joint Instability
Preliminary questions [42092]

42093 the veteran had the laxity of the joint capsule or a stabilising ligament at side and site of the body at some time.

42094  the veteran has established the causal connection between the laxity of the joint capsule or a stabilising ligament and VEA service for joint instability.

42096   the veteran has established the causal connection between the laxity of the joint capsule or a stabilising ligament and VEA service for the clinical onset of joint instability.

42099  the veteran has established the causal connection between the laxity of the joint capsule or a stabilising ligament and operational service for the clinical onset of joint instability.

or

42100  the veteran has established the causal connection between the laxity of the joint capsule or a stabilising ligament and eligible service for the clinical onset of joint instability.

or

7334     the clinical onset of the condition under consideration occurred after the end of the veteran's last period of VEA service.

7335     the condition under consideration permanently worsened.

42098   the veteran has established the causal connection between the laxity of the joint capsule or a stabilising ligament and VEA service for the clinical worsening of joint instability.

42101  the veteran has established the causal connection between the laxity of the joint capsule or a stabilising ligament and operational service for the clinical worsening of joint instability.

or

42102  the veteran has established the causal connection between the laxity of the joint capsule or a stabilising ligament and eligible service for the clinical worsening of joint instability.

Clinical onset and operational service [42099]

42103 on operational service, the veteran had the laxity of the joint capsule or a stabilising ligament to side and site of the body.

42104 on operational service, the veteran had the laxity of the joint capsule or a stabilising ligament to side and site of the body at the time of clinical onset of the joint instability.

42105 the laxity of the joint capsule or a stabilising ligament, at the time of clinical onset of the joint instability, on operational service, was due to the veteran's serious default, wilful act or serious breach of discipline.

or

42106 the veteran had the laxity of the joint capsule or a stabilising ligament to side and site of the body due to an illness or injury which is identifiable.

42107 as a consequence of the identified illness or injury, the veteran had the laxity of the joint capsule or a stabilising ligament, to the side and site of the body, at the time of the clinical onset of joint instability.

42108  the identified illness or injury, which caused the laxity of the joint capsule or a stabilising ligament affecting side and site of the body, is causally related to operational service.

Clinical onset and eligible service [42100]

42109 on eligible service, the veteran had the laxity of the joint capsule or a stabilising ligament at side and site of the body.

42110 as a causal result of eligible service, the veteran had the laxity of the joint capsule or a stabilising ligament at side and site of the body.

42111 as a causal result of eligible service, the veteran had the laxity of the joint capsule or a stabilising ligament, at the side and site of the body, at the time of the clinical onset of joint instability.

42112 the laxity of the joint capsule or a stabilising ligament, at the time of clinical onset of the joint instability, on eligible service, was due to the veteran's serious default, wilful act or serious breach of discipline.

or

42106 the veteran had the laxity of the joint capsule or a stabilising ligament to side and site of the body due to an illness or injury which is identifiable.

42107 as a consequence of the identified illness or injury, the veteran had the laxity of the joint capsule or a stabilising ligament, to the side and site of the body, at the time of the clinical onset of joint instability.

42113  the identified illness or injury, which caused the laxity of the joint capsule or a stabilising ligament affecting side and site of the body, is causally related to eligible service.

Clinical worsening and operational service [42101]

42103 on operational service, the veteran had the laxity of the joint capsule or a stabilising ligament to side and site of the body.

42114 the veteran had the laxity of the joint capsule or a stabilising ligament at side and site of the body, during operational service, as a casual result of operational service.

42115 as a causal result of operational service, the veteran had the laxity of the joint capsule or a stabilising ligament to side and site of the body at the time of the clinical worsening of joint instability.

42116 the laxity of the joint capsule or a stabilising ligament, at the time of clinical worsening of the joint instability, on operational service, was due to the veteran's serious default, wilful act or serious breach of discipline.

or

42106 the veteran had the laxity of the joint capsule or a stabilising ligament to side and site of the body due to an illness or injury which is identifiable.

42117 as a consequence of the identified illness or injury, the veteran had the laxity of the joint capsule or a stabilising ligament to side and site of the body at the time of the clinical worsening of joint instability.

42108  the identified illness or injury, which caused the laxity of the joint capsule or a stabilising ligament affecting side and site of the body, is causally related to operational service.

42118 the clinical onset of the joint instability occurred prior to that part of operational service to which the identified illness or injury, as a consequence of which the veteran had laxity of the joint capsule or a stabilising ligament to side and site of the body, is causally related.
