When used in conjunction with the Orthopedic Salvage System or Comprehensive? Segmental Revision System, the Compress Device is designed to replace the distal and/or proximal femur and/or humerus in cases of severe bone loss. The Compress Device exemplifies Wolff’s Law – the principle that bone, when stressed, remodels to become stronger through dynamic bone compression. This creates a stable, bone-implant interface for biologic fixation1-3 and helps to prevent stress shielding.?
