Lumbar canal stenosis:a patient
Written by:Julian is 68 years and for 3 years suffering from back pain. Besides a few months ago that whenever he walks right leg hurts. Now also left him injured, has ramps in the legs. Believes that much more tired than before. Le utterly legs. He has consulted the GP and this rule after vascular problems, has sent you the neurosurgeon.
-¿Que tal
?
- Well, but I lose leg strength. Whenever I can walk less. I've brought a lumbar magnetic resonance imaging.
-Look, what is observed in the resonance is having a Lumbar Canal Stenosis. (Figure 1). A lumbar narrow channel due to osteoarthritis. These are surgical cases if the disease is progressive, if every time you walk less range without pain and loses leg strength. Besides the lumbar resonance is important electromyogram, to inform us of the importance of injury to the nerves of the lower extremities. If they fail all treatments including the pharmacological, rehabilitation and radiofrequency rhizotomy, advise surgical intervention.
-¿In the intervention consisting
?
-is called decompressive laminectomy. We conducted a“windows” in the back of the vertebra bone marrow to have space, is free from the oppression of the bone. We try to leave the bone of the middle part, the spinous apophyses, to minimize instability and thus avoid the use of screws. (Figure 2 )
-¿, is very dangerous
?
-Thanks to modern techniques and fixation through the spinous processes this technique is quite grateful, without the vertebral mobility miss and reducing both incision and possible complications. (Figure 3)
