Lumbar pain, important cause of complaints and loss of working days in the active population, is originated in 30% of cases by arthrosis in facet joints, which are small joints in the posterior surface of vertebrae, establishing contact between consecutive vertebrae and stabilizing the spine. Pain caused by such arthroses in the lower back, often irradiating to the buttock region, above the knee, may be alleviated and controlled by an approach directed to the facet joints or the medial branches of lumbar nerves, through infiltration or denervation, guided by image – procedures that are available in the Pain Unit of Hospital da Luz Arrábida. “Infiltration may temporarily alleviate low back pain, allowing adequate rehabilitation activity viewing to resume daily life activities without pain complaints. In the absence of improvement after more conventional therapy, facet joint denervation may be performed to provide relief for long-lasting symptoms”, explains anaesthesiologist Humberto Costa Rebelo . These procedures are performed in the Unit of Pain Treatment of Hospital da Luz Arrábida in cases where conventional medication does not work. Besides complaint improvement, it allows a faster return to professional daily activity.
