Dr. David Steven surgically treats a wide range of neurological conditions, including:
Spinal Column & Spinal Cord Disorders
- Spinal Stenosis (Cervical, Lumbar): Narrowing of the spinal canal, which can put pressure on the spinal cord and nerves.
- Herniated Disc (Cervical, Thoracic, Lumbar): A condition where the soft inner portion of an intervertebral disc protrudes through the outer ring, potentially compressing nerves.
- Spinal Cord Tumors (Intramedullary, Extramedullary): Abnormal growths within or surrounding the spinal cord that may require surgical removal.
Peripheral Nerve Disorders (Surgical Management)
- Traumatic Nerve Injuries (requiring repair or grafting): Severe injuries to peripheral nerves that may benefit from surgical exploration, repair, or nerve grafting.
- Ulnar Nerve Entrapment (Cubital Tunnel Syndrome - surgical cases): Compression of the ulnar nerve at the elbow, potentially requiring surgical decompression or transposition.
- Carpal Tunnel Syndrome (severe cases requiring surgery): Compression of the median nerve at the wrist, where surgery (carpal tunnel release) may be indicated if conservative treatments fail.
Cerebrovascular Disorders (Requiring Surgical Intervention)
- Subarachnoid Hemorrhage (SAH): Bleeding into the space between the brain and the surrounding membrane, often caused by a ruptured aneurysm.
- Cavernous Malformations (Cavernomas): Clusters of abnormal, dilated blood vessels that can occur in the brain or spinal cord and may cause bleeding or seizures.
- Cerebral Aneurysms (Unruptured & Ruptured): A bulge or ballooning in a blood vessel in the brain, which can leak or rupture, causing a hemorrhagic stroke.
This list is not exhaustive. For personalized advice regarding your specific neurosurgical condition, please consult with Dr. David Steven.
- Second Opinion Consultations for Neurosurgical Conditions: Providing expert second opinions on complex diagnoses and proposed surgical or non-surgical treatment plans.
- Peripheral Nerve Tumor Resection (e.g., Schwannomas, Neurofibromas): Surgical removal of tumors arising from peripheral nerves.
- Hydrocephalus Management (VP Shunt, ETV - Endoscopic Third Ventriculostomy): Surgical treatment for abnormal accumulation of cerebrospinal fluid in the brain, including shunt placement/revision and endoscopic procedures.
- Syrinx (Syringomyelia) Decompression Surgery: Procedures to drain or shunt fluid-filled cavities (syrinxes) within the spinal cord.
- Arteriovenous Malformation (AVM) & Dural Fistula Treatment (Surgical Resection, Embolization, Radiosurgery Coordination): Multimodal approaches to treat abnormal connections between arteries and veins in the brain or spinal cord.
- Chiari Malformation Decompression: Surgical procedure to relieve pressure on the cerebellum and brainstem caused by Chiari malformation.
- Pre-Surgical Planning & Risk Assessment: Detailed evaluation to determine surgical candidacy, optimize patient condition before surgery, and discuss potential risks and benefits.
Note: This list provides a general overview. Neurosurgical treatment plans are highly individualized. Discuss with Dr. Steven for care relevant to your specific condition.

- Are consultations and neurosurgical procedures with Dr. Steven, a Neurosurgeon, covered by Ontario Health Insurance Plan (OHIP) in ON?
- Medically necessary consultations with a licensed Neurosurgeon like Dr. Steven, as well as most diagnostic imaging reviews and provincially insured neurosurgical procedures (e.g., for tumors, spine conditions, aneurysms), are generally covered by Ontario Health Insurance Plan (OHIP) in ON when a referral from a family doctor or another specialist is in place. Some advanced technologies, specific implantable devices, or purely elective/cosmetic procedures may have different coverage. It's crucial to discuss coverage specifics with Dr. Steven's office, the hospital's financial services, or Ontario Health Insurance Plan (OHIP) prior to any major procedure.
- Do I need a referral to see Dr. Steven, a Neurosurgeon?
- Yes, a referral from your family physician, an emergency room physician, or another specialist (like a neurologist or oncologist) is almost always required to see a Neurosurgeon such as Dr. Steven. Neurosurgical conditions are typically complex and require initial assessment and investigation before a neurosurgical consultation is appropriate. The referral ensures coordinated care and that you are directed to the right specialist.
- What are some common procedures a Neurosurgeon performs?
- Neurosurgeons perform a wide variety of intricate procedures. Common surgeries include craniotomies (opening the skull) for brain tumor removal, aneurysm clipping, or hematoma evacuation; spinal surgeries like laminectomies or discectomies for nerve decompression, and spinal fusions for instability; and placement of shunts for hydrocephalus. Dr. Steven would be able to discuss specific procedures relevant to your condition. Many neurosurgeons also have subspecialty interests, such as pediatric neurosurgery, spine surgery, or vascular neurosurgery.
- Does Dr. David Steven perform minimally invasive neurosurgery?
- Many neurosurgeons, including potentially Dr. Steven, utilize minimally invasive surgical (MIS) techniques when appropriate for the patient's condition. These techniques involve smaller incisions, specialized instruments, and often advanced imaging guidance, which can lead to reduced pain, shorter hospital stays, and faster recovery compared to traditional open surgery. You should ask Dr. Steven if minimally invasive options are suitable for your specific neurosurgical needs.
