Femoral Shaft Frx: Reaming vs Non Reaming: - Wheeless' …
two reamers on femoral IM pressure increases and fat intravasation; - AO and Howmedica reamers were tested in four groups with different combinations of driving speed and revolution rate per minute in both femurs in a sheep model.
Intramedullary reamer failure in orthopaedic surgery: Two case …
Jun 7, 2023 · We present two cases of reamer failure during femoral nailing which illustrate the rare occurrence of intraoperative instrument failure. Our report also underscores the importance of routinely inspecting reaming equipment and provides …
Femoral Reaming: for THR - Wheeless' Textbook of Orthopaedics
- goal: ream close to endosteal cortex, which has strongest cancellous bone; - enter medullary canal w/ curet, & ensure that there are no perforations; - this is esp important w/ osteoporotic bone; - to enlarge medullary canal of diaphysis, use of medullary nail reamers may be necessary;

Surgical Technique
In many cases, due to femoral deformity, an extended trochanteric osteotomy could be performed to facilitate more direct access down the femoral canal. The 140 mm length Distal Starter Reamer is designed to obtain clear access to the femoral canal prior to distal reaming.
An unpredictable complication of femoral reaming: When the reamer …
We report an unusual complication of trapped bone fragments between the reamer and the cortex during intramedullary nailing of a simple femur shaft fracture. All Attempts to withdraw the reamer were unsuccessful. The fragments had to be removed through an open incision.

Surgical Technique
Note: Femoral canal reamers are not included in the kit. If required, please see stem dimensional data (page 26) to aid in reamer selection. If reamers are required, using reamers in carefully increasing diameters is recommended to avoid unintended removal of proximal bone.
Antegrade nailing for Simple, transverse, middle 1/3 fractures
Overaggressive reaming should be avoided because it may cause heat necrosis of the femoral canal. This applies especially for narrow midshaft canals (9 mm or less in diameter).
The Reamer/Irrigator/Aspirator Reduces Femoral Canal Pressure …
Apr 19, 2008 · The reamer/irrigator/aspirator is a surgical instrument designed for use during femoral canal entry to increase the canal size and remove intramedullary fat and may prevent this pressure increase.
