Plain-English summary
American Contract Systems, Inc. is recalling four models of medical device convenience kits nationwide in Colorado: Lower Extremity Models NCEX20I and NCEX20J, and Total Knee Pack Models NCTK31K and NCTK31L. All kits contain Specialist Blend Cast Padding (Item QTX30-322NS). Approximately 850 kits are affected.
Test results show that ethylene oxide and ethylene chlorohydrin (EO/ECH) residuals in the cast padding component exceeded acceptable limits. These elevated residuals may lead to a loss or lack of functionality in the cast padding, which could result in delayed or prolonged treatment, procedures, or therapy.
Patients or healthcare facilities who have received or are using these kits should contact American Contract Systems, Inc. for further guidance. The specific lot numbers and expiration dates for each model are documented in the FDA recall notice Z-1916-2025.
