1. Lumbar disc Extrusion – an observational study Part 3 Vinod Naneria Recurrences on MRI Girish Yeotikar Arjun Wadhwani Choithram Hospital & Research centre, Indore,
2. Purpose of presentation• Conservative treatment is well accepted method of treatment of PID.• There is no need to frighten the patient for possible hypothetical complications.• In our experience, a mono radiculopathy never deteriorates to poly neuropathy.• Poly neuropathy is a separate incident in the cases of pre-existing disc pathology.
3. Recurrence – after surgery• Recurrence has been noted to occur in 5 to 15% of cases surgically treated for primary lumbar disc herniation.• Recurrence after surgery for recurrence increased to 27%.• Incidence of recurrence is very high in cases operated for annular tear and is lowest when there is extruded disc fragment.
4. Recurrent lumbar disc herniation after discectomy: outcome of repeat discectomy. Dai LY, Zhou Q, Yao WF, Shen L. Surg Neurol. 2005 Sep;64(3):226-31;No factors such as age, sex, traumatic events, timesof prior surgery, level of herniation, side ofrecurrence, pain-free interval, duration of recurrencesymptoms, walking capacity, the preoperative JOAscore, associated spinal stenosis, procedures ofrevision surgery, and dural tear were found to be ofpredictive value for a prognosis of revision surgeryfor recurrent disc herniation.
5. Surgery -complications• Discectomy-related complications occur in 15 to 30% of cases and include haemorrhage, soft-tissue infection, nerve root injury, dural tear, recurrent or residual disc herniation, epidural scar formation, discitis, arachnoiditis, pseudomeningocele, facet joint fracture (iatrogenic or stress related), spinal stenosis, and epidural hematoma, mechanical instability.
6. Reference• Carragee, et al., prospectively evaluated disc herniation types, rate of re-herniation, and rate of reoperation. They divided disc herniations into four shape-based groups:• 1) fragment–fissure herniations (disc fragment and small anular defect);• 2) fragment–defect herniations (large disc fragment with massive posterior annular tear);• 3) fragment contained discs (incomplete anular tear);• 4) absence of fragment-contained herniations (annular prolapse).
7. Reference• Of the four groups, the fragment–fissure type herniations were associated with the best outcomes, lowest rate of re-herniation (1%), and required the fewest re-operative procedures (1%).• Those with annular prolapse were associated with the worst outcomes, with 38% of patients experiencing recurrent or persistent symptoms.

10. Comments• First attack in 2007 – with a large disc protrusion with EHL weakness.• Improved clinically• Recurrence in Feb 2011 without any deficit.• Finally – disc extrusion occur in Sept 2011 without any deficit.• Off duty for a month in Feb 2011 and another month in Sept 2011.• Last follow up – Sept 2012 - Happy
11. Case summary - 2
12. comments• Three years follow up• First follow up MRI showed reduction in size and absorption a large piece of extruded disc in three months time.• Recurrence of back pain and further extrusion at same level in Jan 2011.• Some reduction in size in April 2011.• Recurrence can occur at the same level.

31. comments• Initial MRI just had a contended disc at L5 – S1 in 2008.• Recurrence with multiple level disc in Nov – 2011. No neurological deficit.• Recurrence in May 2012 with extrusion of L5 – S1 disc and quadaequina with temporary loss of bladder control.• Prompt surgery with removal of loose piece from L5 – S1 space and discoidectomy at L4 – L5 relieved her.• Improving neurological status at last follow up Sept 2012.
