Hello . . . my husband just had a 3D CT Myelogram this morning due to continued pain in back, numbness & tingling in billateral legs.  Written report states in conclusion, that there is a small ventral extradural defect at L2-3 with apparent nerve root cut off at the right.  His followup appt is not until Oct 29th for results, so I am trying to find out what that means, prior to appt., so that we may talk intelligently with his surgeon and know what to expect, what it means and what we can expect may be done about it.  His fusion at L4 & 5 was done Aprill 11th,2014 and had 3 consecutive surgeries within 5 weeks as he developed a hospital acqired infection, as well as 8 weeks of IV ABX.  He has not had any relief of pain since the initial surgery.Could I get an answer on what that means, what to expect and what can be done about what the Myelogram conclusion stated?

### output:

Hi, thank you for providing the brief history of your husband. As he has already undergone the spinal fusion at L4-L5 levels, and recurrent surgeries of the back it appears that the lumbar disc are not in good shape. Also, the MRI indicates the nerve root injury and needs a thorough examination. Besides, post surgery if he is not relieved of pain than the surgery couldn't help him due to muscle weakness which keeps on leading to nerve root compression. Also, to Control the symptoms of numbness, tingling and pain you can arrange a meeting with a physical therapist and undergo Therapeutic ultrasound therapy and TENS therapy for pain relief. Besides, exercises will help but before undergoing any exercises the surgical neurological assessment is advised. As the pain is chronic in nature instant recovery cannot be expected as well. Kindly keep the patience and meet up the surgeon to discuss further. In my clinical practice, such cases with spinal surgeries respond well to physical therapy. And slow, steady recovery is achieved.
