AB  - OBJECTIVE: The aim of this anatomical study was to compare the effects of the 
      prone and lateral decubitus positions in endoscopic disc surgery on the Kambin's 
      triangle (KT) and neural foramina zones in the lumbosacral region. METHODS: The 
      study included 32 healthy volunteers (16 females and 16 males). Bilateral KT 
      areas (KTA) and neural foraminal areas (FA) of the L4-L5 and L5-S1 levels in the 
      prone and lateral decubitus positions were calculated depending on the freehand 
      region of interest measurements on magnetic resonance images. KTA and FA values 
      for each side and level in the prone and lateral decubitus positions were 
      compared. RESULTS: Mean left KTA value in the prone and right lateral decubitus 
      positions was 0.58 cm(2) and 0.69 cm(2), respectively, for L4-L5; and 0.69 cm(2) 
      and 0.78 cm(2), respectively, for L5-S1 levels. Mean right KTA values in the 
      prone and left lateral decubitus positions were 0.54 cm(2) and 0.65 cm(2) for 
      L4-L5; and 0.69 cm(2) and 0.81 cm(2) for L5-S1, respectively. The differences in 
      the KTA between prone and lateral decubitus positions for both levels and both 
      sides were statistically significant (p=0.05). Only the difference in the FA 
      between the prone and lateral decubitus positions at L5-S1 level on the right 
      side was statistically significant (p=0.05). CONCLUSION: The KTA is wider in the 
      lateral decubitus position than in the prone position at the levels of L4-L5 and 
      L5-S1.
