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.
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 ...
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.

The constellation of symptoms caused by craniocervical instability is known as "cervico-medullary syndrome" [4] and includes: [5] [6] [7] Anxiety disorder; Bobble-head doll syndrome, a sensation that the skull may fall off the cervical spine; Clumsiness and motor delay; Cognitive and memory decline; Double or blurred vision; Dysphagia, or the ...
Ehlers-Danlos syndrome is a genetic disorder in humans and animals which can cause connective tissue disorders, hyper mobility, bruising, and a range of other issues. ... The Future For This Cat ...
People with joint hypermobility may develop other conditions caused by their unstable joints. [6] [7] These conditions include: Subluxations or dislocations, especially in the shoulder; Joint instability causing frequent sprains, tendinitis, or bursitis when doing activities that would not affect others. However, a 2018 study reports that while ...
Piano key sign: Dorsal DRUJ instability can cause a protruding ulna head, which can be pressed down. When you release the pressure, it will spring back in position again, just like a piano key. DRUJ stress test: With this provocation maneuver, the wrist is held in pronated or supinated position, while the physician attempts to manipulate the ...
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 ...
