Hemispherectomy is a surgery that is performed by a neurosurgeon where an unhealthy hemisphere of the brain is disconnected or removed. There are two types of hemispherectomy. Functional hemispherectomy refers to when the diseased brain is simply disconnected so that it can no longer send signals to the rest of the brain and body.
There are normally two sesamoid bones on each foot; sometimes sesamoids can be bipartite, which means they each comprise two separate pieces. The sesamoids are roughly the size of jelly beans. The sesamoid bones act as a fulcrum for the flexor tendons, the tendons which bend the big toe downward. Symptoms include inflammation and pain.

An Oregon baby underwent surgery to remove half of his brain due to a rare disorder and seizures. Jackson Williamson was just 3 months old when he started suffering seizures.
Neurosurgery can range from removing an entire hemisphere (hemispherectomy), a small lesionectomy, or multiple transections to try to disconnect the abnormal tissue from the rest of the brain (multiple subpial transsections). Physical therapy should be considered for infants and children with muscle weakness.
A surgeon working in Scotland has developed a way to remove brain tumours the size of apples through patients’ eyebrows in what is believed to be a world-first for the procedure.
Selective dorsal rhizotomy can alleviate contractures caused by spasticity from before the surgery takes place; also it prevents any more contractures or spasticity from occurring in the future. With or without rhizotomy, the only way contractures can ever be relieved is via orthopaedic surgery. Fixed orthopaedic deformities of the legs caused ...
