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 stenosiswith bilateral stenosis

? Lysis dilema always

Full facet sign on MRI

Investigation MRI

DYNAMIC X RAY IN LAT VIEW

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.

Decompression + TLIF by using tubular retractor

Cage insertion

Post op

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).
