Modular Aiming Device (ModAD)
Intramedullary locked nailing of the tibia, femur, and humerus is a technically demanding procedure. To achieve distal locking accurately, in the least possible time, and with the least possible exposure to radiation is a major concern with the free-hand technique. The Modular Aiming Device (ModAD) enables distal and proximal locking for most common Synthes Titanium Intramedullary Nail Systems without the need for an image intensifier. It has been recognized that some deformation of locked intramedullary nails is inevitable as they are inserted, and that, therefore, a simple aiming arm, mounted on the proximal end of the nail alone, will not sufficiently provide accurate distal aiming. To compensate for insertional implant deformation, a proximally mounted radiation independent aiming device was developed. The ModAD System covers UHN, UFN/CFN and UTN/CTN (in TAN and stainless steel) and will be provided modular. The handling of the ModAD is similar to the existing Distal Aiming Device (DAD) for UTN which will be replaced by the ModAD.
