There are several types of bone grafts, but most commonly an autograft (patient bone) or allograft (donor bone) are used. In an instrumented spinal fusion, instruments are used to stabilize the spine while the bones fuse. Read more

Pituitary Tumors – Symptoms and Treatment

The pituitary gland secretes hormones responsible for growth, metabolism regulation, fluid balance, testosterone/estrogen regulation, sperm/egg production, and milk production after birth. Tumors can grow inside of the gland and are rather common. Read more
