Operative Technique Freehand Distal Locking The freehand technique is used to insert Fully Threaded Locking Screws into both distal M/L holes in the nail. Rotational alignment must be checked prior to locking the nail statically. Multiple locking techniques and radiolucent drill devices are available for freehand locking. The critical step with any freehand locking technique, proximal or distal, is to visualize a perfectly round locking hole with the C-Arm. The center-tipped Ø4.2×180 Drill (1806-4270S) is held at an oblique angle to the center of the locking hole (Fig. 32 & 33). Upon X-Ray verification, the Drill is placed perpendicular to the nail and drilled through the lateral and medial cortex. Confirm in both the A/P and M/L planes by X-Ray that the Drill passes through the hole in the nail (Fig. 34). Fig. 32 Fig. 33 After drilling both cortices, the screw length may be read directly off of the Screw Scale, Long (1806- 0365) at the green ring on the center tipped Drill (Fig. 35). As with proximal locking the position of the end of the drill is equal to the end of the screw as they relate to the far cortex. Alternatively, the Screw Gauge (1806-0480) for Freehand technique can be used instead of the 50mm Fig. 34 Fig. 35 Screw Scale, Long to determine the screw length. Routine Locking Screw insertion is employed with the assembled Long Screwdriver Shaft and Teardrop Handle. Repeat the procedure for the other distal Locking Screw (Fig. 36). Fig. 36 20
Operative Technique End Cap Insertion After removal of the Target Device, an End Cap may be used. Four different sizes of End Caps are available to adjust the nail length and to reduce the potential for bony ingrowth into the proximal thread of the nail (Fig. 37). Standard +5mm +10mm +15mm The End Cap is inserted with the Long Screwdriver Shaft and Teardrop Handle after intra-operative radiographs show satisfactory reduction and hardware implantation (Fig. 38 & 39). Fully seat the End Cap to minimize the potential for loosening (Fig. 40). Fig. 37 The wound is closed in the usual manner. Fig. 38 Fig. 39 Fig. 40 21
