Patient guide

Conditions we treat

A plain-language description of each condition and the treatment options we offer. The right treatment for any one person depends on their symptoms, imaging and overall health, and is decided together at consultation.

8 conditions

Spine

Conditions of the cervical, thoracic and lumbar spine.

Spine surgery
  • Lumbar spinal stenosis

    Narrowing of the spinal canal in the low back that causes leg pain, heaviness or numbness with walking or standing, often eased by sitting or bending forward.

    OptionsDecompression (laminectomy or laminotomy), with fusion if the spine is unstable

  • Disc herniation and sciatica

    Disc material pressing on a nerve root, causing pain that spreads down the leg (sciatica) or, in the neck, into the arm. Many cases improve within weeks.

    OptionsMicrodiscectomy when pain persists or weakness develops

  • Degenerative cervical myelopathy

    Compression of the spinal cord in the neck that can cause hand clumsiness, imbalance and difficulty walking. It tends to progress, so early assessment matters.

    OptionsACDF, corpectomy, laminoplasty, or laminectomy and fusion

  • Radiculopathy (pinched nerve)

    Compression of a nerve root causing pain, numbness, tingling or weakness in an arm or leg.

    OptionsIn the neck, ACDF or posterior foraminotomy. In the low back, microdiscectomy or decompression

  • Spondylolisthesis

    Slippage of one vertebra relative to the next, which can narrow the space for nerves and cause back and leg pain.

    OptionsDecompression, with or without fusion

  • Degenerative disc disease

    Age-related changes in the discs and joints of the spine. These are very common on imaging and often cause no symptoms. Surgery is considered when they compress the nerves or spinal cord.

    OptionsTreated according to the resulting nerve or spinal cord compression

  • Spinal fractures

    Traumatic or osteoporotic fractures of the vertebrae, assessed for stability and for pressure on the nerves.

    OptionsObservation, bracing, or surgical stabilization

  • Chronic neck and back pain

    Long-standing pain without nerve compression rarely improves with surgery. We assess whether a structural, treatable cause is present and recommend non-surgical care when it is not.

    OptionsUsually non-surgical care

6 conditions

Neuro-oncology

Tumours of the brain and spine.

Neuro-oncology
  • Meningioma

    Usually benign tumours arising from the membranes that cover the brain and spinal cord. Many grow slowly.

    OptionsObservation with serial imaging, surgical resection or stereotactic radiosurgery

  • Glioma and glioblastoma

    Tumours arising from the brain’s glial cells, ranging from slow-growing low-grade gliomas to glioblastoma.

    OptionsBiopsy or maximal safe resection, followed by radiation and chemotherapy as indicated

  • Brain metastases

    Tumours that have spread to the brain from cancer elsewhere in the body.

    OptionsSurgical resection, stereotactic radiosurgery or both

  • Intradural spinal tumours

    Tumours inside the covering of the spinal cord, such as meningiomas and nerve sheath tumours, which can cause pain, numbness or weakness.

    OptionsMicrosurgical resection

  • Spinal metastases

    Cancer that has spread to the vertebrae, which may cause pain, instability or spinal cord compression.

    OptionsDecompression and stabilization, usually combined with radiation

  • Incidental brain findings

    Lesions found on a scan done for another reason.

    OptionsAssessment, surveillance imaging or biopsy

8 conditions

Cerebrovascular

Conditions of the blood vessels of the brain and neck.

Cerebrovascular care
  • Brain aneurysm

    A weak, bulging area of a brain artery. Many are found incidentally, and small aneurysms are often safely monitored.

    OptionsSurveillance imaging, coiling (with balloon or stent assistance) or flow diversion

  • Carotid stenosis

    Narrowing of the carotid artery in the neck, which raises the risk of stroke.

    OptionsMedical therapy, with carotid stenting for selected patients

  • AVM and dural arteriovenous fistula

    Abnormal connections between arteries and veins in or around the brain that can cause bleeding, seizures or pulsatile tinnitus.

    OptionsObservation, embolization, surgery or radiosurgery, often in combination

  • Pulsatile tinnitus

    A rhythmic sound in the ear that keeps time with the heartbeat. In some patients it is caused by venous sinus stenosis or a dural fistula.

    OptionsVenous sinus stenting or embolization when a treatable cause is found

  • Idiopathic intracranial hypertension (IIH)

    Raised pressure around the brain without another identifiable cause. It typically causes headaches and can threaten vision.

    OptionsVenous sinus stenting for selected patients with venous sinus stenosis, alongside care from neurology and ophthalmology

  • Acute ischemic stroke

    A blocked artery supplying the brain. Suspected stroke is an emergency. Call 911.

    OptionsEndovascular thrombectomy for large-artery blockages, through the emergency department

  • Aneurysmal subarachnoid hemorrhage

    Bleeding around the brain from a ruptured aneurysm. This is a medical emergency.

    OptionsEmergency aneurysm treatment, usually by coiling, through the emergency department

  • Intracerebral hemorrhage

    Bleeding within the brain tissue.

    OptionsAssessment for an underlying vascular cause, and follow-up

5 conditions

Trauma and general

Injury, bleeding and cerebrospinal fluid disorders.

Trauma and urgent care
  • Head injury

    Traumatic brain injury that needs neurosurgical assessment, imaging review or follow-up.

    OptionsAssessment and follow-up. Surgery when there is significant bleeding or pressure on the brain

  • Chronic subdural hematoma

    A collection of old blood between the brain and its covering, often after a minor fall and most common in older adults.

    OptionsObservation, burr-hole drainage, or middle meningeal artery embolization in selected patients

  • Hydrocephalus

    A build-up of cerebrospinal fluid in the brain’s ventricles.

    OptionsVentriculoperitoneal shunt or endoscopic third ventriculostomy

  • Shunt malfunction

    Blockage or failure of a shunt that drains cerebrospinal fluid, which can cause headache, drowsiness or vomiting.

    OptionsShunt assessment and revision

  • Spinal cord injury

    Injury to the spinal cord from trauma.

    OptionsAssessment and follow-up after acute care

No conditions match your search. Try another term, or contact our office.

A sudden severe headache, new weakness or numbness, trouble speaking, loss of bladder or bowel control, or loss of consciousness is an emergency. Call 911 or go to the nearest emergency department.
