Lumbar stenosis (narrowing of the spinal canal in the lower back) is one of the most common causes for spine-related disability and one of the main reasons for spinal surgery in older adults (Friedly et al., 2014).
Primary stenosis is a congenital condition; secondary stenosis can have several possible causes, such as accidents, arthritis, neurological pathologies, tumors etc. Degenerative stenosis is the most common cause. The segments of L4-L5 are the most frequently affected ones, followed by L3-L4, L5-S1 and L1-L2.
At the moment surgery and physiotherapy have similar outcome according to current literature. Therefore, full disclosure regarding which treatment, conservative and/or surgical, is essential to come to the most beneficial conclusion for the patient (Friedly et al., 2015). Other conservative treatments are steroid injections, physiotherapy, rest and pain medications.
