Osgood-Schlatter condition is a common knee injury in young athletes. It's caused by an irritation of the tibial tubercle, the bump on the lower end of your thigh bone where it meets your knee. In most cases, this bump becomes inflamed and tender when you put weight on it during sports or other activities. The pain can be severe enough to keep you from playing sports or doing other things that make use of your kne  Read More

Panmyelopathy describes a collection of symptoms that result from severe spinal compression. When something compresses (squeezes) the spinal cord, it can’t function properly. That can lead to pain, loss of feeling, or difficulty moving certain parts of the body. 1. The spine encases the spinal cord — a collection of nerves that carry messages between your brain and body. 2. Usually, the bones of  Read More

Although researchers have been able to establish a clear syndrome with characteristic or “core” symptoms, much about the disorder is not fully understood. Several factors including the small number of identified cases, the lack of large clinical studies, and the possibility of other genes influencing the disorder prevent physicians from developing a complete picture of the potential associated symptoms and prognosis. Therefore, it  Read More

There is no one specific test for diagnosing relapsing polychond  Read More

Conservative treatments — such as rest, ice, and physical therapy — sometimes are all that's needed to recover from a rotator cuff disease or injury. If your injury is severe, you might need surgery. 1. Therapy Physical therapy is usually one of the first treatments suggested. Exercises tailored to the specific location of your rotator cuff injury can help restore flexibility and strength to your should  Read More

Symptoms of Roussy-Lévy Syndrome are similar to other hereditary motor sensory neuropathies in that there is weakness and atrophy of the leg muscles with some loss of feeling. People with this syndrome have difficulty walking and a lack of reflexes and deformity of the foot or feet (pes cavus).

The condition was first reported by Dyggve, Melchior and Clausen in 1962 in three of eight siblings where the father was the mother's paternal uncle. Because of physical appearance and the present of acid mucopolysaccharides in the urine, Dyggve believed that their affected pat  Read More

Spinal muscular atrophy type 3 is an inherited progressive neurodegenerative disease. SMA is caused by alterations (mutations) in the genes that make proteins needed to support motor neuron function. The degree of genetic involvement determines what type of SMA you have as well as the severity of symptoms.1 Since SMA is a genetic condition, there are no specific lifestyle factors known to cause or prevent it.  Read More

Familial hypophosphatemia is a rare inherited disorder characterized by impaired transport of phosphate and often altered vitamin-D metabolism in the kidneys. In addition, phosphate may not be well-absorbed in the intestines. The hypophosphatemia resulting from these impairments can lead to a skeletal defect called osteomalacia, which can be considered a softening of bones. Familial hypophosphatemia also results in rickets, a childhood bone di  Read More
