The Synthes 312.67 Double Drill Sleeve 3.2/6.5 mm is a precision guide instrument used in large fragment orthopedic surgery, especially when using Locking Compression Plates (LCP). As a double drill sleeve, it accommodates two different drill bit sizes (3.2 mm and 6.5 mm) within a single sleeve guide, allowing the surgeon to use either drill according to the screw or pilot requirements without switching to separate guides. This helps maintain alignment and support during drilling, especially when preparing holes for screws of different diameters in the same operative field, reducing the risk of misalignment or drift that could lead to screw pull out or plate misfit.

With an overall length of about 6‑1/2 inches, the Synthes 312.67 and sleeve shaft lengths of ~1‑9/16 to 2 inches, the instrument provides sufficient reach and stability in the soft tissue corridor while maintaining control and visibility. The two sleeves (3.2 mm and 6.5 mm) are likely mounted in series or nested in a way that they align properly with the plate holes and ensure that the drill bit remains centered. This reduces the chance of heat generation, deviation of the drill bit, and inadvertent damage to surrounding bone or soft tissue. Also, being part of the Synthes Large Fragment LCP set means that its tolerances are likely high, materials are surgical‐grade (stainless steel), and finishing is precise to allow smooth drill insertion and removal, sterilization, and reliable re‑use.

Clinically, this double drill sleeve is a time‑saving and safety enhancing tool. Surgeons benefit from having one guide that can handle two commonly used drill sizes instead of swapping sleeves or guides, which streamlines the procedural workflow, reduces instrument clutter, and limits operative time. In addition, drill sleeves help protect soft tissues (muscles, periosteum) during drilling and guide the drill bit straight into plate holes, improving fixation strength and reducing screw misplacement. However, as with all orthopedic instrumentation, meticulous inspection before use is needed: check for burrs or damage in the inner bore, ensure the sleeve alignment is accurate, verify the two sleeve diameter interfaces are not worn, and ensure the instrument has been properly sterilized. Worn sleeves can lead to drill wobble or mismatch, which could compromise screw trajectory or stability.
