Extremity Lock™ is a patient immobilization solution designed to support stable, reproducible positioning of arms, legs, hands, feet, knees, and shoulders during radiotherapy—anatomical regions that have historically posed challenges and were often underserved by standardized positioning solutions.
Extremity treatments frequently rely on improvised setups that introduce variability, inefficiency, and risk. Extremity Lock™ was developed to provide a consistent, standardized approach for these difficult-to-position regions, helping Radiation Therapists achieve reliable immobilization while supporting faster treatment delivery and improved patient safety.
Extremity Lock™ is optimized to support patient setup for both traditional radiotherapy treatments for cancer and low-dose radiotherapy (LDRT) workflows for benign conditions, where consistent positioning and efficient daily delivery are important.
By providing standardized immobilization for these anatomically challenging regions, Extremity Lock™ supports reproducible setup across fractions and efficient daily treatment delivery.

Before Extremity Lock™, many extremity and peripheral anatomy treatments depended on ad hoc positioning methods that varied between therapists and across fractions—often increasing setup time and uncertainty.
Extremity Lock™ introduces a purpose-built approach that helps therapists position patients efficiently and consistently, supporting shorter setup times and smoother treatment delivery.
Standardized immobilization approach for arms, legs, hands, feet, knees, and shoulders
Simple, intuitive setup requiring minimal adjustment
Easy handling during application and removal
Reproducible extremity positioning across fractions
Clear positioning logic that supports repeatable results
Reduced setup time compared to improvised extremity supports
Designed to integrate with IGRT workflows where applicable and common extremity & peripheral anatomy treatment workflows
Imaging-compatible materials suitable for planning and verification
Patient safety is especially important when treating extremities and peripheral anatomy, where unintended movement or unstable positioning can compromise delivery.
Together, these features contribute to increased patient safety and more predictable treatment sessions.
Secure immobilization designed to minimize unintended movement
Stable positioning that reduces the need for repositioning once the patient is set
Comfortable support that accommodates a range of anatomies
Reduced handling and adjustment during setup, supporting safer patient positioning
CDR Systems positioning and immobilization solutions are designed to integrate into modern radiotherapy environments, including gantry-based and bore-based systems, and to support common clinical workflows such as CT (including 4D-CT where applicable), MRI (where applicable), PET-CT, and on-board imaging (kV/MV, CBCT), across techniques including IMRT, VMAT, SRS, SBRT, and related approaches.
Extremity Lock™ is intended for use by Radiation Therapists and Radiation Oncology teamsdelivering radiotherapy to extremity and peripheral anatomical regions, including arms, legs, hands, feet, knees, and shoulders.
Extremity Lock™ introduces a standardized, therapist-friendly approach to extremity immobilization—helping reduce setup variability, support faster treatment delivery, and enhance patient safety across cancer radiotherapy and low-dose radiotherapy workflows for benign conditions.
