About Orthopedic Sizing Trials for Joint Replacement

Matching the correct medical implant size to the patient’s unique joint and bone structure is a critical step for successful joint replacement surgery. From patient to patient, there is a variation in bone and joint size, just like we see with different feet sizes or other anatomy from person to person. In many joint replacement surgeries such as knee or hip implants and others, patients are fitted with the correct implant size to match their specific bone and joint. Orthopedic joint replacement implant manufacturers provide different sized orthopedic trial implants to help the surgeon determine the proper fit for the implant and the patient. During joint replacement surgery, the surgeon will use the orthopedic sizing trial to ensure the appropriately sized medical implant matches the patient for joint replacement. Orthopedic trials are typically color-coded to match corresponding implant sizes and are sterilized after surgery using steam autoclave for re-use.

Why Radel® & Heat Stabilized Polypro for Hip, Knee & Shoulder Orthopedic Sizing Trials?

Orthopedic sizing trials require materials that can handle repeated steam sterilization cycles, biocompatibility, and excellent dimensional stability.

radel r5500 orthopedic sizing trials for joint replacement hip, knee, shoulder

Two materials that fit these parameters include Radel® R5500 PPSU Polyphenylsulfone & Propylux® HS Heat Stabilized Polypropylene; Radel® has become the industry standard for orthopedic sizing trials, with Propylux® HS becoming a popular alternative. In addition to both materials handling repeated sterilization, they are also FDA, USP Class VI & ISO 10993-5 compliant and offer excellent dimensional stability. Radel® & Propylux® are available in a wide range of standardized commercially available colors.

Common Medical Grade Plastics used in Orthopedic Applications by Sterilization Method

Radel® is excellent for the five most common sterilization methods: Ethyle Oxide Gas (ETO), Steam, Dry Heat, Plasma & Gamma Radiation, which is the best out of the most commonly used orthopedic sizing trial plastics. Propylux® HS is excellent for ETO & Steam and good for Plasma. Below is a chart showing four common medical-grade plastics used in orthopedic applications by sterilization method.

Material	Ethylene Oxide Gas / ETO	Steam 121 C / 134 C	Dry Heat 160 C	Plasma	Gamma Radiation
PPSU - Radel®	Excellent	Excellent	Excellent	Excellent	Excellent
