- Spiral Blade:
- Transverse interlocking - (Standard Aiming Arm)
- accepts 4.9 mm locking bolt;
- static Locking:
- dynamic Locking:
- more proximal of the two holes;
- allows up to 8 mm of controlled axial movement, for
optimal fracture dynamization;
- optimally screw is 2 mm longer than diameter;
- use steinman pin w/ ruler to measure
Screw Length;
- Locking Sleeve: (Special Aiming Arm)
- permits angled insertion of a 4.9 mm Locking Bolt into
calcar,
for treating reverse oblique
Subtrochanteric Fractures, or as
an option for standard proximal locking;
- angled at 130 deg nail to screw angle;
- as w/ other techniques, 3.2 mm guide wire is passed into proximal
femur, & 13 mm cannulated drill bit is passed over this & reamed
to depth of 100 mm;
- use the URFN Broach to enlarge opening to greater than 15 mm
to accommodate the 130 deg locking sleeve;
- prior to assembly of insertion instruments, 130 deg locking sleeve
slides onto the proximal nail end;
- Locking Cap:
- 15 mm End Cap for 130 deg Locking Sleeve;
- securely locks 130 deg locking sleeve to the nail
- choice of 0, 10, & 20 mm sizes, provides option to extend nail
length, allowing optimal positioning of the locking bolt;
