Synthes 357.389 Drill Sleeve 8.0/4.0mm Orthopedic

• Model: 357.389
• 8.0/4.0mm

The Synthes 357.389 drill sleeve is a guided instrument component designed to precisely control drilling during orthopedic surgery, particularly when placing or preparing for trochanteric fixation nails. The dual-diameter (8.0 mm external, 4.0 mm internal) configuration allows it to accommodate a 4.0 mm drill bit (or similar) while being stabilized through an 8.0 mm outer fit in the protection or guide sleeve. This design helps reduce lateral wobble and ensures accurate alignment of the drill bit with the pathway required by the nail system.

At approximately 164 mm in length, the sleeve is long enough to reach through soft tissue, guide over the nail or insertion pathway, and maintain an adequate working distance for both the surgeon and the drill. Its length strikes a balance between providing stability and allowing maneuverability. Being made of stainless steel gives it the needed rigidity and resistance to wear, while maintaining sterility and strength under repeated sterilization procedures.

In the context of the trochanteric fixation nail system, this drill sleeve’s role is to protect surrounding soft tissues and bone during drilling, to guide the bit so that it enters at the correct trajectory relative to the nail, and to protect the insertion site. By controlling drill bit drift and reducing unnecessary damage, it helps improve overall accuracy of screw or blade placement, which is critical for fixation stability, healing, and reduction of complications.
