The PURIST
Leg Positioning System™

Measurable, reproducible positioning for anterior hip replacement

  • Staff-friendly operation with a small storage footprint
  • Compatible with existing OR tables
  • Can be operated by surgeon through sterile drape

Anterior approach hip replacement places specific demands on patient positioning.

Femoral exposure and implant placement require controlled extension, external rotation, and adduction of the operative limb — often with dynamic intraoperative adjustments as the procedure progresses.

PURIST exists to support those demands with predictable, repeatable positioning that remains stable under load.

System overview

The PURIST enables all essential leg movements for anterior THR in a condensed and efficient system.

It is built to perform independent DA THR movements on a graduated scale, allowing precise intraoperative control of traction and rotation. Traction and rotation can be adjusted simultaneously, either directly by the surgeon, or by other personnel.

The system is designed to behave consistently throughout the procedure, supporting reproducible positioning rather than intermittent correction.

Intraoperative control & workflow impact

  • Effortless leg movements
  • Simultaneous adjustment of traction and rotation
  • Graduated, predictable adjustments rather than coarse repositioning
  • Surgeon can control traction and rotation through the drape
  • Most of the functions can be measured in mm or degrees

By providing a precise and operator-friendly system for repeatable positioning, the PURIST supports a smoother workflow for surgical teams performing DA THR procedures.

Product Specification
"I have been using the PURIST leg positioning system for the past few years at both hospitals in our community. I routinely do my total hips DA, and the PURIST is my preferred means of positioning.  Use of the PURIST is quick and easy, and it has a very small footprint which makes for expeditious room set-up and turnover.  I have used other positioning devices, including having extensive experience with the ARCH system.  After using the PURIST, I am spoiled.  It is simple, reliable, and in my opinion, indispensable for efficient OR work flow."
David R. Dietrich, MD Gulf Coast Regional Medical Center, Panama City, FL, USA
"The Purist Leg Positioning System has completely transformed the way I perform Direct Anterior Approach (DAA) total hip replacements. I use it for every single case because it makes the procedure more efficient, predictable, and precise. The system saves me valuable time in the operating room while ensuring optimal positioning, which directly benefits my patients. It’s easy to use, reliable, and enhances surgical consistency—allowing me to focus on delivering the best possible outcomes.  I highly recommend it for any surgeon performing DAA hip replacements."
Supreet Bajwa, MDWockhardt Hospital, Mumbai, India
“The PURIST leg positioner for anterior hip surgery is an  effective alternative to bigger, more expensive fracture tables.  It is small in size and doesn’t take up much floor space and can work with any standard operating table.  Setting up the table is easy and easily taught. X-ray and fluoro are easy to obtain with no obstruction.  Working the leg positioner can be taught easily to OR personnel and executed by them safely. Exposure to the hip is equivalent with other systems.  I believe the cost of the positioner is much lower than self-standing traction tables making it a more feasible option for smaller, lower volume hospitals or surgery centers.”
