Operative Technique Apposition/Compression Locking Mode In transverse, axially stable fracture patterns, active apposition/compression increases fracture stability, may enhance fracture healing, and may allow for early weight bearing. The S2 Femoral Nail, Compression provides the option to treat a femur fracture with active mechanical apposition/ compression prior to leaving the operating room. 10mm Caution: Distal locking with at least two Fully Threaded Locking Screws must be performed prior to applying active, controlled apposition/compression to the fracture site (see page 22, Fig. 42). Fig. 46 If active apposition/compression is required, a Partially Threaded Locking Screw (Shaft Screw) is inserted via the Target Device in the dynamic position of the oblong hole. This will allow for a maximum of 10mm of active, controlled apposition/compression. In order to insert the Partially Threaded Screw (Shaft Screw), drill both cortices with the Ø4.2×340 Drill (1806-4260S). Next, drill the near cortex, ONLY, with the Ø5×230mm Drill (1806-5000S). Note: After the opposite cortex is drilled with the Ø4.2×340mm Drill, the correct screw length can be read directly off of the calibrated Drill at the end of the Drill Sleeve (Fig. 46) After the Shaft Screw is inserted, the Nail Holding Screw securing the nail to the insertion post is removed, leaving the insertion post intact with the nail (Fig. 47). This will act as a guide for the Compression Screw. The Compression Screw is inserted with the Long Screwdriver Shaft and Teardrop Handle through the insertion post (Fig. 48). As The Compression Screw is advanced against the 5mm Partially Threaded (Shaft Screw), it draws the distal fracture fragment toward the fracture site, employing active apposition/compression. Note: Apposition/compression must be carried out under X-Ray control. Over compression may cause the nail or the Shaft Screw to fail. Fig. 47 Fig. 48 Note: After inserting the Compression Screw, the End Cap can no longer be used. 24
Operative Technique Nail Removal Nail removal is an elective procedure. The End Cap or the Compression Screw is removed with the Long Screwdriver Shaft and Teardrop Handle (Fig. 49). The Universal Rod is inserted into the driving end of the nail. All Locking Screws are removed with the Long Screwdriver Shaft and Teardrop Handle (Fig. 50). The optional Long Screw Capture Sleeve may be used on the Screwdriver Shaft. The Slotted Hammer is used to extract the nail in a controlled manner (Fig. 51). A captured Sliding Hammer (1806-0175) is available as an optional addition to the basic instrument set. Fig. 49 Fig. 50 Fig. 51 25
