Lumbar Disc Injury/Herniation from MVA

Understanding Lumbar Disc Injury/Herniation from MVA

Also known as: Herniated Disc, Slipped Disc, Lumbar HNP, Sciatica from Car Accident A lumbar disc injury from an MVA is damage to one of the shock-absorbing discs of the lower back — typically at L4-5 or L5-S1 — when axial loading combined with sudden flexion tears the annular fibers and allows the nucleus to herniate against a nerve root. The result, when the sciatic roots are involved, is radiculopathy — leg pain in a distribution pattern that follows the compressed nerve. Roughly 80-90% of lumbar disc herniations improve with conservative care over six to twelve weeks. Deep low back pain combined with sharp, burning, or electrical pain shooting into the buttock, thigh, calf, and sometimes the foot is the classic presentation.

Coughing, sneezing, bending forward, and prolonged sitting worsen it; lying down usually helps. Many patients pinpoint the moment their leg pain first appeared — often days or weeks after the accident — when they bent to put on shoes or stood up from a low chair. The accident is the clinically and legally relevant cause. Flexion-distraction (the Cox technique) is the cornerstone of our approach — it has specific evidence for lumbar radiculopathy.

McKenzie directional exercises centralize leg symptoms. Neural mobilization for the sciatic nerve, motor control exercise, and spinal decompression for acute radicular pain complete the protocol. When pain is severe, we co-manage with pain management for epidural steroid injections and coordinate with orthopedics or neurosurgery if red flags emerge. Neurologic findings are documented carefully at every visit.

We may recommend: flexion-distraction/Cox, spinal decompression, McKenzie protocol, Class IV laser, corrective exercise, DNS, TENS/e-stim Seek immediate care if: You develop saddle anesthesia, loss of bladder or bowel control, rapidly progressive leg weakness, or foot drop — these may indicate cauda equina syndrome and require emergency surgical evaluation.
