Ankle clonus Clonus is a set of involuntary and rhythmic muscular contractions and relaxations. Clonus is a sign of certain neurological conditions, particularly associated with upper motor neuron lesions involving descending motor pathways, and in many cases is accompanied by spasticity (another form of hyperexcitability).

axial compression and rotation of cervical spine to the side of symptoms causes pain Stellwag's sign: Karl Stellwag von Carion: endocrinology: thyrotoxicosis: infrequent and/or incomplete blinking, accompanied by Dalrymple's sign: Still's murmur: Sir George Frederick Still: paediatric cardiology: subaortic stenosis, small Ventricular septal defect
Ankle problems occur frequently, having symptoms of pain or discomfort in the ankles. [1] [2] Mild ankle pain can often be cured by home treatments, although these may be slow to take effect. Specialized physicians are needed if the condition is severe, especially if it has been caused by injury. [2]
The major tissues affected are nerves and muscles, where irreversible damage starts to occur after 4–6 hours of cessation of blood supply. [4] Skeletal muscle, the major tissue affected, is still relatively resistant to infarction compared to the heart and brain because its ability to rely on anaerobic metabolism by glycogen stored in the cells may supply the muscle tissue long enough for ...
Myoclonus is a brief, involuntary, irregular (lacking rhythm) twitching of a muscle, a joint, or a group of muscles, different from clonus, which is rhythmic or regular. Myoclonus (myo-"muscle", clonus "spasm") describes a medical sign and, generally, is not a diagnosis of a disease.
Avascular necrosis (AVN), also called osteonecrosis or bone infarction, is death of bone tissue due to interruption of the blood supply. [1] Early on, there may be no symptoms. [1] Gradually joint pain may develop, which may limit the person's ability to move. [1] Complications may include collapse of the bone or nearby joint surface. [1]

Gorham's disease (pronounced GOR-amz), also known as Gorham vanishing bone disease and phantom bone disease, [1] is a very rare skeletal condition of unknown cause.It is characterized by the uncontrolled proliferation of distended, thin-walled vascular or lymphatic channels within bone, which leads to resorption and replacement of bone with angiomas and/or fibrosis.
