ABSTRACT
The plethora of anatomical variations in scientific literature has made it very difficult for health care
professionals like surgeons and interventionists to remember anatomical variations during the procedure
and there are high chances that the variations they are going to find during a procedure will always
be different from the one that is already reported in some or the other way. Finding similarities and
dissimilarities with previously reported versions of variations entirely depends on experience and education
of interventionists. The continuous addition of variations on one side adding to our existing scientific
knowledge but on other side It is almost impractical and herculean task to remember all variations and
continuous addition making it more difficult to distinguish the significant from not so significant facts
and apply these facts in clinical practice. Evidence based Anatomy can do justice to this situation but
robust studies related to anatomical variations are still lacking as we have plenty of case reports related to
anatomical variations having many scientific flaws. As an academic exercise reporting anatomical variations
may be fine but in the real world such things cause confusion and affect decision-making. We must try and
learn to draw a line and avoid adding gibberish to scientific literature as an extension of our professed moral
duty towards science.

1. Introduction
Anatomical variation is a presentation of body structure
with morphological features different from those described
in several anatomy textbooks as Normal.

Anatomical
variation is a divergence from what is generally perceived
as “normal anatomy” and that may or may not be
related to a disease state. “Normal” may have many
meanings depending on the context in which the term is
used. In context of human gross anatomy, whatever is
written in the book “Gray’s Anatomy: The Anatomical
Basis of Clinical Practice” is assumed to be normal by
most people. Anatomical variations includes any variation
in muscle structure, origin/insertions and innervation,

ligament attachments and morphology, branching patterns
of blood vessel , nerves and their course and positions,
and bone morphology and accessory bones, various
foramen/foramina etc. which are frequently documented
by anatomists during their routine dissection or clinicians
during surgeries.
As a fact No two humans can be exactly similar
externally and internally.

It is altogether a different matter
whether such differences are ‘significant’ in terms of
healthcare or not. A study found that experienced clinicians
reported seeing variations in their practice on a monthly
(39%), weekly (25%), and daily (21%) basis.

Reporting of
anatomical variations from all over the world has become
so extensive. In current era of preponderance of journals
and injudicious race of publishing articles, we are adding
anatomical variations irrespective of their significance or
