Our patient was a journeyman framer on a multi-story residential project. The incident itself was unremarkable — a two-person carry of a sheathing bundle, an awkward pivot, an audible pop in his low back, and a wave of pain that ran down the back of his right thigh and into the outer foot by the end of the shift. He finished the day, drove home, slept badly, and called his foreman the next morning. He was sent to the on-site occupational clinic and started the workers' comp process.
By the time we saw him at LAOSS — about seven weeks after the injury, after the initial WC authorization for an orthopedic spine consult cleared — he had a textbook S1 radiculopathy. Sharp, electric pain down the posterior right leg, numbness on the outer foot, and a weak gastroc that buckled on toe-raises. His MRI, which had taken six weeks to authorize, showed a moderate-sized right paracentral L5-S1 disc herniation flattening the traversing S1 nerve root. History, exam, and imaging all agreed: this was a structural problem causing a neurological symptom in a patient who used his back for a living.
