- Discussion:
- Miss A Nail Aiming Jig permits single or dual, 7.0 mm cannulated screw or 6.5 mm cancellous screw fixation of the femoral neck frx before nail insertion, for a sound surgical approach to a demanding clinical situation;
- may be placed anterior (or anterior and posterior) to path of nail;
- permits screw insertion at one of four nail screw angles:
- 100, 110, 120, or 130 deg;
- Technique:
- using standard techniques for entering the piriformis fossa and use the 13 mm cannulated reaminer to 100 mm;
- connect the URFN Insertion Handle to the Dummy nail for Miss A Nail;
- manually insert the nail into the proximal femur until the slot of the Dummy nail is in line with the femoral neck axis;
- choose the angle of insertion;
- insert the 5.6 mm/3.2 mm wire sleeve (for 6.5 mm cancellous bone screw) or 5.6 mm/2.0 mm wire sleeve (for 7.0 stainless steel cannulated screws) into the superior bushing of the Miss A Nail Jig;
- for 7.0 mm Stainless Steel Cannulated Screws, insert the 2.0 mm threaded Guide Wire, 300 mm, thru wire sleeve into femoral head;
- drill for the stainless steel screws using the extra long, 4.5 mm cannulated drill bit, and tap as needed;
- following IM nail insertion, a 4.9 mm locking bolt may be inserted
