Ligamentous laxity or ligament laxity can appear in a variety of ways and levels of severity. In most people, ligaments (which are the tissues that connect bones to each other) are naturally tight in such a way that the joints are restricted to 'normal' ranges of motion. This creates normal joint stability.
Achard syndrome is a syndrome consisting of arachnodactyly, receding lower jaw, and joint laxity limited to the hands and feet. [1] Hypermobility and subluxations of the joints, increased lateral excursion of the patellas and other findings reflect the increased ligament laxity. It is clinically similar to Marfan syndrome. [2]
There is some evidence that ligament laxity may be associated with an increased tendency to cavitate. [ 14 ] In 2015, research showed that bubbles remained in the fluid after cracking, suggesting that the cracking sound was produced when the bubble within the joint was formed, not when it collapsed. [ 10 ]
Excessive laxity of the posterior transverse ligament can lead to atlantoaxial instability, a common complication in patients with Down Syndrome and Ehlers–Danlos syndrome. Laxity has also been hypothesized as the cause of degenerative hypertrophy and mechanical atlantoaxial stress. [3] Degenerative processes can give rise to transverse ...
Sacroiliac joint dysfunction is an outcome of either extra-articular dysfunction or from intraarticular dysfunction. SI joint dysfunction is sometimes referred to as "sacroiliac joint instability" or "sacroiliac joint insufficiency" due to the support the once strong and taut ligaments can no longer sustain.
Lentigo in cats is a common dermatological condition characterized by the presence of small, flat, brownish spots on the skin — particularly around the lips, nose, and eyelid margins. Unlike in ...
Cats may be poisoned by many chemicals usually considered safe by their human guardians, [citation needed] because their livers are less effective at some forms of detoxification. [31] [32] Some of the most common causes of poisoning in cats are antifreeze and rodent baits. [33] Cats may be particularly sensitive to environmental pollutants. [34]
A recessive autosomal (non-sex linked) form of feline cutaneous asthenia has been identified in Siamese cats and related breeds. In the homozygous state, it is apparently lethal. Feline cutaneous asthenia is similar to the Ehlers–Danlos syndrome of humans. Cats with cutaneous asthenia cannot be grasped by the scruff, as this may tear away.
