3 Femoral Preparation Canal Reaming for a Straight Stem: Obtaining a clear access to the femoral canal is essential to ensure proper alignment of revision stem. After careful removal of the previous stem, cement, and debris, the femoral canal is gradually reamed by attaching the T-handle or power device to the Straight Reamer . Based on the stem size determined preoperatively, start reaming with the smallest size or at least 2 mm smaller than predicted stem size until appropriate depth is obtained. Offered reamer size increment is 0.5 mm in diameter. It is recommended that at least 0.5 mm press-fit for normal bone quality. Occasionally, a line-to-line reaming may be required to treat a hard bone. Canal Reaming for a Curved Stem: When preparing the femoral canal for a 230 mm curved stem, utilize the flexible reaming assembly ( Guide Wire, Flexible Reamer Shaft and Flexible Reamer Head ) to follow the nature bow of the femur. Advance the flexible reamer into the canal, making sure it passes through diaphysis. Fluoroscopy may be used to ensure the appropriate depth and direction during reaming process. Sequentially reaming by 0.5 mm increment until the anticipated diameter and depth is achieved.
