21.5 cm, 8%”
double ended
The 11-921-21 is an Alderdyce pattern elevator, a double ended instrument measuring 21.5 cm, or roughly 8 inches, designed for periosteal elevation and controlled tissue handling during bone exposure. The Alderdyce pattern has a place in surgical sets where a dependable, straightforward elevator is needed for lifting periosteum cleanly away from the underlying bone surface.
Its double ended construction allows the surgeon to work with two tip configurations from a single instrument, which can reduce the number of tools required on the tray during a procedure that involves both broad and more targeted elevation.
As part of our bone surgery instruments, the Alderdyce elevator supports procedures where clean separation of periosteum from bone is necessary before further bone work, such as plating, grafting, or reconstructive steps, can proceed.
Double ended design for versatility during periosteal elevation
21.5 cm overall length for mid range surgical access
Established elevator pattern used for controlled bone exposure
Slim shaft profile supports precise handling near bone surfaces
A dependable periosteal elevator is a mainstay of any bone surgery set, and the Alderdyce pattern offers surgeons a familiar, well proportioned option for procedures that require clean, controlled exposure of the underlying bone.
