Dr Sachin Pathak Associate Spine Surgeon Oyster and Pearl Hospitals, Pune
Gr 1 lumbar spondylolisthesis Traetment plan Degenerative Only decompression will increase more instability Interspinus devices : Traditional fixation fusion with TLIF MISS
How to select case for MISS Mono radiculopathy with predominant back pain due to instability Not useful in multilevel severe lumbar canal stenosis with bilateral stenosis ? Lysis dilema always Full facet sign on MRI
Total 22 cases of gr 1 listhesis Mean age group 39
Advantages Reduced intraoperative Blood Loss Reduced postoperative drain Less Post operative Back pain Less Pain during Rehabilitation Reduced hospital Stay Less multifidus muscle atrophy Decreased incidence of surgical site infections
Procedure Step 1 Mark pedicles and entry points made using trocars percutaneously. Dilators are inserted and screws and rods inserted bilaterally same procerdure used. The side from where disc is removed a larger incision taken and tubular retractors used to remove disc and insert cage.
Under GA prone position Operative time 2hr 30 min initial cases Now 1hr 30 min Avg Blood loss 50 cc anasthesia and analgesia requirement was less during procedure No drain
Mobilised after 48 hrs Pain controlled by dynapar and paracetamol Hospital stay 3 days
Problems I have faced initially Scared for c arm exposure 2 cases I have to open paraspinally as rod introducer broken Screws not like mirror image on xray ? Decompressed completely or not
I m happy about No dural leak in any case no Screw mal position giving rise to neuralgic pain or defecit Mobilization quick Pain over opt site drastically reduced
disadvantages Significant learning curve Pseudarthrosis could be due to the more difficult disc space preparation and grafting using tubular retractors Pedicle screw malposition, cage displacement and iatrogenic foraminal stenosis (14.2%) Increased radiation exposure Duration of surgery greater than conventional open technique (3 Hrs after training nearly 1-1.5hrs reduction in earlier time).
