R L4-5 Postero-lateral disc herniation and a common peroneal nerve entrapment of the right leg, how do we differentiate between these? Signs and symptoms only no tests Localised pain would be with the nerve entrapment, where as the disc bulge would affect all areas within the dermatome. The gait of the patient with the disc bulge would be highly antalgic and not with the nerve Flexion movements and sitting will cause pain with a disc. Dynamic lateral recess stenosis L5-S1 right side and erector spinae muscle strain on the right side would be differentiated with what signs and symptoms? E. spin musc pain can go up and down the back where as a stenosis would travel down the leg. Aggravated by static posture would aggravate both. Flexion would aggravate the e.spin mm but relieve the stenosis. Radicular pain would be associated with LRS Referred pain, with respect to reproducing the problem is not consistent, radicular pain is. Which condition is likely to be associated with a neurological deficit, early or classic instability? Classic Instability. Early instability may lie dormant for many years until a minor event triggers it. E.g. the patient simply picks something up and their back goes. Give 2 examples of orthopaedic conditions associated with classic instability – 1. stenosis and 2. spondylolisthesis, and 3. possibly disc. Spondylolisthesis is not a diagnosis, not a tissue in lesion. Lig problems, disc, mm, neurogenic claudication (all of the above basically) can lead to a spondy. DJD is also not a diagnosis or a tissue in lesion for the same reasons. Loose Back Syndrome – idiopathic hypermobility that usually occurs in young people particularly young women. Short lever adjustments only for these people. Refferred P or radicular p a) extend below the knee? NO above the knee and proximal to the elbow. Can, but not usually. Radicular P goes right to the end. b) Distribution? See above c) Symptoms: Localisation – radicular, superficial – rad, deep – referred. d) Sensory Changes – subjective if present e) Motor Changes – obj if present musc testing weakness - radicular f) Reflex changes: More with rad, less with ref g) Tension signs: SLR – more likey to be neg for ref, pos for rad.
