      Indian population.

AB  - A three dimensional triangular space 'the Kambin's triangle (KT)' present on the 
      dorsolateral aspect of the intervertebral disc, is considered to be a safe area 
      for transforaminal approaches. It allows access to the exiting and traversing 
      nerve roots, the thecal sac and to the intervertebral disc spaces. Our aim was to 
      calculate the area of the triangle by measuring the height and base at all the 
      intervertebral spaces bilaterally in the lumbar region in North West Indian 
      cadavers and to assess the diameter of circle inscribed within this triangle 
      which will correspond to the size of cannula inserted for the minimally invasive 
      transforaminal approaches in this population. Five randomly chosen adult cadavers 
      were used for this study. After clearing the area, the exiting nerve was 
      identified. The height and base of the bony KTs (n=40) were measured with the 
      help of digital Vernier's calliper (accuracy 0.02 mm) to calculate the area of 
      the KT. There is a steady increase in the area of the bony KT reaching maximum at 
      the level of L4-5 intervertebral space. Statistically there were no differences 
      in the calculated areas between right and left side. The mean diameter of 
      inscribed circle within the triangle also showed gradual increase from 5.82 mm at 
      L1-2 level, reaching maximum value of 7.26 mm at L4-5 level on the right side 
      while on the left side the values were 5.66 mm and 8.16 mm respectively. Careful 
      anatomical consideration is of utmost importance in transforaminal approaches 
      during surgical or interventional procedures in this region. Cannula having 
      external diameter ranging 6-8 mm is recommended for any interventional approach 
      through Kambin's space.
