Standard Specification for Intramedullary Reamers

ABSTRACT
This specification provides requirements for material, dimensions and tolerances, finish and marking, and care and handling for reamers intended to cut a cylindrical path along the medullary canal of diaphyseal bone. Intramedullary reamers are commonly used to prepare the medullary canal for the insertion of intramedullary fixation devices (IMFD). As such, the relationship between the intramedullary reamer diameter and the IMFD's diameter are considered. In general, intramedullary reamers consist of two types: one-piece reamer—a design where the reamer shaft and cutting head are permanently attached to each other; and Modular Reamer—a design where the reamer shaft and cutting head are two separate components, fixed to each other temporarily at the time of use via a geometric connection, for example, dovetail joint.
SCOPE
1.1 This specification provides requirements for material, dimensions and tolerances, finish and marking, and care and handling for reamers intended to cut a cylindrical path along the medullary canal of diaphyseal bone.  
1.2 Intramedullary reamers are commonly used to prepare the medullary canal for the insertion of intramedullary fixation devices (IMFD). As such, the relationship between the intramedullary reamer diameter and the IMFD's diameter are considered.  
1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

Standard Specification for
Intramedullary Reamers
This standard is issued under the fixed designation F1611; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A
superscript epsilon (´) indicates an editorial change since the last revision or reapproval.
