Flexible Monobloc Reamers

Christopher Finkemeier, Mark Lee, Andrew Oppy, Martin Hessmann


In response to various clinical demands (cutting performance, usability), new Flexible Monobloc Reamers have been developed to ream an intramedullary bone canal in preparation for insertion of implants.

The new monobloc reamers are provided in reamer diameters from 8 mm to 18 mm in 0.5 mm increments and in reamer lengths of 480 and 620 mm (Fig 1). Each reamer has a one-piece design with a flexible shaft. Compared with modular reamers there is no need for intraoperative reamer head exchange. All reamers have a hybrid reamer head design that incorporates both front- and side-cutting features. The deeply fluted reamer heads function to reduce intramedullary pressure and increase the flow of bone chips and marrow. A wear indicator in the Graphic Case allows surgeons to understand the extent of the reamer deterioration.

With the new Flexible Monobloc Reamers, surgeons can choose simplicity and enhanced usability for the reaming procedure that has the potential to be challenging and time consuming when using modular reamer system.
