Operative Technique Static Locking Mode For static locking of the S2 Femoral Nail Compression, both proximal M/L Locking Screws must be used when ever possible. The Long Tissue Protection Sleeve together with the Long Drill Sleeve and the Long Trocar are positioned through the most distal static locking hole on the Target Device. A small skin incision is made, and the assembly is pushed through, until the Tissue Protection Sleeve is in contact with the lateral cortex of the femur (Fig. 26). The Trocar is removed, while the Tissue Protection Sleeve and the Drill Sleeve remain in position. Fig. 26 To ensure accurate drilling, and easy determination of screw length, use the center tipped, calibrated Ø4.2×340 Drill (1806-4260S). The centered Drill is forwarded through the Drill Sleeve and pushed onto the cortex. After drilling both cortices, the screw length may be read directly off of the calibrated Drill at the end of the Drill Sleeve, Long (Fig. 27). If measurement with the Long Screw Gauge (1806- 0325), is preferred, first remove the Long Drill Sleeve, and read the screw length directly at the end of the Long Tissue Protection Sleeve (Fig. 28). Caution: Make sure the Tissue Protection Sleeve/Drill Sleeve Assembly is seated on bone prior to selecting final screw length. Note: The position of the end of the Drill as it relates to the far cortex is equal to where the end of the screw will be. Therefore, if the end of the Drill is 3mm beyond the far cortex, the end of the screw will also be 3mm beyond. Note: The Screw Gauge, Long is calibrated so that with the bend at the end pulled back flush with the far cortex, the screw tip will end 3mm beyond the far cortex (Fig. 28). 18 50mm Fig. 27 Fig. 28
Operative Technique When the Drill Sleeve is removed, the correct Locking Screw is inserted through the Tissue Protection Sleeve using the Screwdriver Shaft, Long (1806-0227) with Teardrop Handle (702429). The screw is advanced through both cortices. The screw is near its’ proper seating position when the groove around the shaft of the screwdriver is approaching the end of the Tissue Protection Sleeve (Fig. 29). Caution: The coupling of Elastosil handles contains a mechanism with one or multiple ball bearings. In case of applied axial stress on the Elastosil handle, those components are pressed into the surrounding cylinder resulting in a complete blockage of the device and possible bending. Fig. 29 To avoid intra-operative complications and secure long-term functionality, we mandate that Elastosil handles be used only for their intended use. DO NOT HIT hit on them. Repeat the locking procedure for the other statically positioned M/L Locking Screw (Fig. 30). Caution: In unstable fracture patterns, static locking should always be performed with at least two Locking Screws proximally and two Locking Screws distally. Fig. 30 Note: If secondary dynamisation is planned, the most proximal M/L Locking Screw may be inserted in the dynamic position of the oblong hole (Fig. 31). This allows for controlled dynamisation of the fracture in cases of delayed union after removal of the most distal proximal Locking Screw. Fig. 31 19
