A cannulated retrograde reamer configured to be disposed over a guidewire that is adjustable to create tunnels of multiple different diameters. The cannulated retrograde reamer substantially reduces the risk of tunnel malposition and/or misalignment, and can be adjusted to create a range of tunnel diameters, thereby allowing inventory levels to be reduced for a surgical case.

Surgical instrument

A cannulated retrograde reamer is adjustable to create tunnels of multiple different diameters. The cannulated retrograde reamer has a first tubular shaft and a second tubular shaft disposed about the first tubular shaft. A cutting member is pivotably coupled to the distal end of the first tubular shaft. The distal end of the second tubular shaft is configured to engage and disengage the proximal end of the cutting member by the rotation and axial movement of the second tubular shaft relative to the first tubular shaft to open and close the cutting member. The cannulated retrograde reamer substantially reduces the risk of tunnel malposition and/or misalignment, and can be adjusted to create a range of tunnel diameters, thereby allowing inventory levels to be reduced for a surgical case.
