The PURIST Orthopedic Leg Positioner is designed to boost efficiency and surgeon control throughout the direct anterior Total Hip Replacement (THR) procedure. It is a surgical leg holder that enables all essential leg movements for direct anterior THR in a condensed and efficient manner.
How PURIST Orthopedic Leg Positioner works
The PURIST Orthopedic Leg Positioner streamlines procedures, supports repeatability, and frees the hands of the surgical team. It is fixed on a mobile base with large casters, making mobility effortless and allowing it to pair with any general surgical table.
Why PURIST Orthopedic Leg Positioner?
It is built to perform independent Direct Anterior (THR) movements on a graduated scale and its enhanced design allows the surgeon to control traction and rotation intra-operatively with precision and without help from non-sterile personnel. Its quick setup, staff-friendly operation, and small footprint make the PURIST popular with busy operating room (OR) teams. Combine the PURIST with any standard OR table to build a superior leg positioning system.
A dedicated orthopedic table is typically expensive, bulky, and challenging to move about the OR and even into storage. The PURIST Orthopedic Leg Positioner offers meticulous surgical positioning capabilities such as independent traction, rotation, extension, and ab/adduction controls, with a smaller footprint, making storage simple.
It is fixed on a mobile base with large casters, making mobility effortless. Easy to store, generally low maintenance, and flexibility to pair with any general surgical table.

The PURIST has controls for fine and gross traction. Fine traction is controlled with the traction hand wheel, and gross traction is controlled by pulling the red handle. Traction, measured in millimeters of length, can be applied from 0 mm to 130 mm. Most surgeons use less than 80mm of traction.
180° of internal or external rotation of the patient’s foot/leg is available. Rotation is controlled in increments of 10 degrees. High levels of external rotation will be used during a Direct Anterior THA case.
The PURIST is capable of 31.5 inches of leg extension. The PURIST traction boot slides along a straight pendulum attached to a gas piston. When a patient’s leg is attached, the pendulum will automatically swing out and follow the natural arc of the leg. The gas strut supports this compensating movement. The patient’s leg can be positioned at infinite positions along the pendulum using a hand wheel that executes the leg extension. The PURIST automatically removes traction during extension and restores traction at 0° extension as a safety feature.
40° of Ab- or Ad-duction is available (80° total). Ab/Adduction is controlled in increments of 10 degrees in either direction using an extendable lever handle. The added length of the extendable lever will give the operator more leverage. The amount of Ab/Adduction can be read on the back of the PURIST.

Are you interested in becoming certified to use the ARCH or even becoming a trainer of other users? Welcome to the ARCH Training Certification Program. We are glad you want to become our equipment's certified user or trainer. STERIS’ certification program for users and trainers is divided into the three tiers below.
This refers to medical professionals who operate the device in the operating room. Level 1 equipment users should know all the information in the following documents. The Level 1 Certification Form can be used if necessary but is not required.
This level is for advanced users, STERIS employees, and third-party representatives who will be in-servicing Level 1 users on the proper use of the ARCH. Level 2 trainers must meet all Level 2 Certification Form requirements.
This level is for STERIS employees and third-party representatives ONLY with the certification to train Level 2 trainers. In addition to all requirements necessary to achieve Level 2 certification, Level 3 trainers must also meet the requirements outlined in the Level 3 Certification Form.
Please click the CONTACT link below and send us a request to start your certification training today.
A: No. Both the ARCH and PURIST systems use femoral support under the patient’s thigh, which acts as a fulcrum to elevate the proximal end of the femur during leg extension.
The Perineal Operative Post and Direct Anterior Approach (DAA) Top 360 accessories have femoral supports with variable heights. Increasing the height of the femoral support will increase the anterior movement of the proximal end of the femur during leg extension. The DAA Top 360 tabletop accessory offers the widest range of femoral support height adjustment, and the height can be changed intraoperatively through the drape.
A: It depends on the surgeon's preference and OR setting. We have PURIST and ARCH users who are very satisfied with the performance of their leg positioning system of choice. The PURIST is designed specifically for anterior hip replacement, and the ARCH can be used for anterior hip replacement and femoral fractures.
ARCH Advantages
PURIST Advantages
For surgeons who currently use full-size fracture tables and are looking for firm, sturdy control of the leg, we usually recommend the ARCH. For surgeons looking for a light, ergonomic, staff-friendly device, we usually recommend the PURIST. However, this is highly variable and depends on individual surgeon preferences, staff familiarity with the anterior approach, surgical volume, geographic location, facility size, etc. Contact us for more information.
A: Neither the ARCH nor the PURIST is designed for hip arthroscopy.
A: Yes, ARCH and PURIST are compatible with most general surgical tables. Over the last 10+ years, we have had very few situations in which our accessories did not fit!
Both our ARCH and PURIST systems are free-standing devices, and the accessories attach to the OR table siderails. Siderail dimensions can vary depending on the country, but this is not a problem. We offer various siderail attachments to fit different types of siderails. Our accessories are currently used in markets with different sizes of siderails, such as the USA, Europe, Australia, and Japan.
There is no need to pair our systems with a traction table. More basic OR tables, such as the STERIS 5095 or AMSCO 3085 SP, are preferred because they have fewer metal structures that could interfere with intraoperative imaging.
A: Follow all requirements of the OR table used. We recommend orienting the table when possible so the long portion of the table base will be situated under the patient’s center of gravity and pointing toward the ARCH or PURIST. This usually provides increased stability. Ensure there is adequate clearance for the C-arm to maneuver into place. Watch the ARCH In-Service Video or PURIST In-Service Video for more info.
A: According to FDA and MDR regulations, ARCH and PURIST are classified as class I medical devices.
A: The ARCH, PURIST, DAA Top 360, OLH, and POP are all designed for patient weights up to 500 lb. (227 kg). However, if the patient weight limit of the OR table is lower than this, the table weight limit takes priority. Ensure to check the orientation of the OR table, as different orientations often have different weight limits. Refer to the OR table user manual to ensure you operate within their specifications.
A: No, the PURIST does not have patient height requirements.
A: About 7’5” (226cm). As leg length and total height are not perfectly correlated, this is an estimated maximum height.
A: Yes. The ARCH, PURIST, and Opposite Leg Holder (OLH) all have a size medium boot in their standard configurations. We also offer a size small boot that can be purchased separately.
A: 61 cm (2’) x 91 cm (3’)
A: Yes, the black perineal post pad is designed to be reusable. Its closed-pore design allows the sealed surface to be easily cleaned. However, we recommend replacement after every 10 cases.
A: No. However, we offer a variety of single-use products that increase patient safety and efficiency, especially in Direct Anterior THA cases.
