No, but I put this together based on available info:

More On Bone Structure

Recently Dr. Michael Hales published in the Strength and Conditioning Journal defined the differences between a short and long torso, and short and long arms. By using a tape measure and the assistance of a lifting buddy, you can measure which deadlift style might be best for you.

Step 1 – Measure the length of your torso starting at the greater trochanter to the top of your head. The greater trochanter is the bony protrusion at the top of your thigh. This measurement should be taken vertically, and not at an angle.
Step 2 – Measure your arm length starting at the bony part located at the top of the shoulder, to the end of the tip of your middle finger. Make sure your arm is straight when taking this measurement.
Step 3 – Measure your height. (Don’t guess)

Torso length. Divide your torso length (in inches) by your height in inches.

Short torso – If this calculated ratio is less than 47%, you have a short torso.
Long torso – If this calculated ratio is greater than 47%, you have a long torso.

Arm length. Divide your arm length (in inches) by your height in inches.

Short arms – If this calculated ratio is less than 38%, you have short arms.
Long arms – If this calculated ratio is greater than 38%, you have long arms.

Comparing Torso And Arm Size To Determine Which Deadlift Style Is Best For You

Now that you have calculated your torso and arm size, use the following chart to determine if you are better suited for conventional or sumo deadlifts:

Short Arms and Short Torso – Either Conventional or Sumo
Short Arms and Average Torso – Sumo Deadlift
Short Arms and Long Torso – Sumo Deadlift

Average Arms and Short Torso – Conventional Deadlift
Average Arms and Average Torso – Either Conventional or Sumo
Average Arms and Long Torso – Sumo Deadlift

Long Arms and Short Torso – Conventional Deadlift
Long Arms and Average Torso – Conventional Deadlift
Long Arms and Long Torso – Either Conventional or Sumo
