Hip Joint Implants

Many advances have been made in the field of hip joint replacement devices over the last 50 years, allowing hundreds of thousands of patients to lead normal and active lives.The technical documentation for hip joint implants requires the verification of device characteristics on the basis of standardized test procedures. Orthotek can conduct these tests with high precesion for both modular and non-modular hip implant systems.
