Alians Ulna 3/3
Indications
The implants of the Alians Ulna range are intended for ulnar shortening osteotomies in adults. Alians Ulna 3/3 brochure
Alians Ulna 3/3 surgical technique video
Technical features
- Monoaxial locking system
- Rack-and-pinion compression device
- Stabilization transfixation screw / compression screw
- Low-profile locking plate
Implant technical features
- Anatomically contoured implant: the edges and tips of the implant are rounded to minimize soft tissue irritation.
- Marks appearing on the implant :
- Proximal and distal ends
- Graduations for checking compression level
Monoaxial fixation
• Ø3.5 mm standard cortical screw for proximal oblong hole (CT3.5Lxx)
• Ø3.5 mm locking screw (SOT3.5Lxx)
• Ø2.8 mm standard cortical screw for pre-angled central hole (CT2.8Lxx): stabilization screw
• Ø2.8 mm lag screw for pre-angled central hole (QBT2.8Lxx) : compression screw
Monoaxial locking system
Features
- The threaded sections under the screw head and inside the hole have strictly the same characteristics (1) :
- Cylindrical internal thread profile,
- Cylindrical external thread profile,
- Screw head cap (2),
- Plate and screw made from the same material: titanium alloy.
Results
- Low profile construct:
- The screw head reaches a mechanical stop in the slot, insuring the locking (3),
- The screw head is buried in the plate.
- Construct limiting the risk of cold welding
- Construct allowing an optimized coaptation of both profiles when locking (4).
Cutting guide and compression device
Components
- 2 blocks (ANC670 and ANC671) allowing to manage the operated side (right or left) and the approach (lateral, dorsal or palmar/volar).
- 2 cutting guides (ANC171/1 and ANC171/2) enabling 2 to 6 mm resections. The indication 'DISTAL' is present on each cutting guide to ensure an appropriate positioning on the block.
