Critical Appraisal of SPORT RCT

This is a presentation on critical appraisal of SPORT RCT using the Graphic Approach to Epidemiology (GATE). It was presented at the Research methodology workshop at IOACON 2016, Kochi.
The SPORT study was a large multicenter randomized controlled trial comparing discectomy versus nonoperative care for lumbar disc herniations. The results of this study are analyzed critically. The study was marred with a high cross over rate making the interpretation of the results confusing. However, it is a landmark paper, and great lessons can be learned by critically analyzing the results. 
I find the GATE framework quite useful for critical appraisal of epidemiological studies. This method was developed by Prof. Rod Jackson from New Zealand.

Minimally invasive microdiscectomy – Surgical Video


This is a surgical video of minimally invasive microdiscectomy.

This is a common operation performed for persistent, severe sciatica due to lumbar disc herniation. Open microdiscectomy is the traditional way for performing this surgery, however, in the recent times, a minimally invasive approach has gained popularity.

Potential advantages of minimally invasive microdiscectomy are limited muscle injury, lesser pain and a shorter hospital stay.

Here we demonstrate a minimally invasive tubular microdiscectomy in a 22-year-old woman with right lower extremity radiculopathy of 6 months duration secondary to a right sided L4-5 disc herniation.
