Objectives:   The   objectives   of   present   study   were   to   find   out   the   measurements   of   Platymeric   index,   Robusticity   index,   and   Foraminal   index,   for   both   right and   left   femurs.   Our   study   was   also   aimed   at   estimation   of   total   length   of   femur   from   Platymeric   index   and   so,   an   attempt   was   made   to   find   out   the accuracy   of   correlation   between   total   length   of   femur   and   Platymeric   index   among   West   Bengal   population.   The   present   study   was   also   designed      to   reveal the number and position of nutrient foramina in respect to the proximal end of femur of both sides. Materials   and   Methods:   The    study   was   undertaken   in   66   adult   intact   human   femurs   obtained   from   Department   of   Anatomy   of   different   Kolkata   based medical colleges, for fulfilling objectives. Bone scale and sliding caliper were used to find out the measurements. Results:   Mean   ±   SD   of   Total   length   of   right   and   left   femur   were   42.44   ±   2.87cm   and   41.85   ±   3.34cm   accordingly.   Robusticity   index   of   left   femur   was   12.50 ±0.83   and   right   was   12.36   ±0.99.   Platymeric      index   of   left   and   right   femur   were   accordingly   89.76   ±9.57   and   93.94   ±14.95   and   Foraminal   index   ranged between   36.28   –   54.98   for   the   left   side   and   33.33   –   62.5   for   the   right   side.   Regression   equation   formula   for   calculating   Total   length   was   Y   =   0.2243   ˣ   X   + 20.69   by   taking   Platymeric   index   as   independent   variable   i.e.   X   and   Total   length   as   dependent   variable   i.e.   Y.   Among   the   total   femurs   examined,   3   showed triple   foramina   and   19   femurs   had   double   foramina.   4   femurs   had   no   nutrient   foramina;   others   had   single   foramina.   All   nutrient   foramina   were   directed proximally. Conclusion:   The   present   study   is   useful   in   calculating   the   length   of   a   long   bone   from   a   given   fragment   which   is   important   mainly   for   medicolegal   and anthropological   purposes.   Morphometric   data   is   important   for   determination   of   sex,   race,   as   well   as   to   radiologists,   rheumatologist   and   orthopedic surgeons for diagnosis and planning of treatment.
