AB  - The mamillary (MP) and the accessory (AP) processes are two important anatomical 
      landmarks in the lumbar vertebral morphology. These two processes form the 
      mamillo-accessory notch (MAN) between them. In the living, the MP and the AP are 
      connected together by the mamillo-accessory ligament (MAL). The medial branches 
      of lumbar dorsal rami pass underneath the MAL. The MAL often undergoes varied 
      degrees of ossification with diverse notching at the junction of these two 
      processes, often with formation of a discrete foramen (MAF). Reports on the 
      distribution of these notches (MAN) and foramina (MAF) are very few and most of 
      them do not discuss such ossification in context of morphology of adjoining 
      structures in the vertebrae. Lumbar vertebral and sacral specimens were screened 
      for three different categories of narrowing at the mamillo-accessory junction: 
      firstly >1/2 notch, secondly (3/4) notch, and thirdly MAF and their distribution 
      patterns were mapped along the lumbar spine. Transverse dimensions of superior 
      facet articulating surfaces [length (a)] and widths of MPs [length (b)] were 
      recorded. Relative widths of the MPs were calculated as index M (a/b). Results 
      suggest associations between the degrees of assimilation of the MPs into the 
      facet joints, the index M values, and the different types of mamillo-accessory 
      junctional anatomy. This study may help to understand if MAN and MAF related 
      dorsal rami entrapment neuropathies arise merely due to osteoarthritic 
      ossification of the MAL or could also be accounted for by facet dimensions or 
      degree of MP-facet fusions that abut close to the mamillo-accessory junctions.
