What intervention is commonly indicated to address a tethered spinal cord?

• A. Surgical release of cord
• B. Physical therapy alone
• C. Observation without intervention
• D. Chemotherapy

Answer: (A)

Tethered spinal cord causes the spinal cord to be abnormally stretched, especially as a person grows, leading to progressive neurological symptoms. The intervention that directly addresses this problem is detethering surgery—surgically releasing the cord from its abnormal attachments (such as a tight filum terminale or lipomyelomeningocele). This relieves traction on the cord and aims to halt or reverse worsening deficits, making it the standard treatment when symptoms or risk of progression are present. Physical therapy can improve strength and mobility, but it does not remove the tether, so it doesn’t solve the underlying cause. Observation without intervention may be considered in some cases, but if there are signs or risk of progression, delaying surgery allows continued traction and potential deterioration. Chemotherapy has no role in treating tethered spinal cord.
