Small Frag Flashcards
(21 cards)
What does LCP stand for?
Locking Compression Plate
What do we aim for with internal fixation?
Reduction
Stable fixation
Early functional mobilisation
Preservation of blood supply
What is a COMBI bone plate hole?
One side of the hole is threaded, the other is smooth
The compression is always directed to the middle of the plate due to what?
The combi holes are reverse on the other half of the plate
How does the conventional screw act on the plate?
It acts by compressing the plate to the bone
How does the locking screw work on the plate?
It is mechanically anchored to the plate without compression
What’s are the differences between locking screws and vortex screws?
Locking screws have a threaded head, a larger core diameter, creates a fixed angle
Cortex screws have a smooth head, smaller core diameter and have a variable angle implantation
What size implants are in the small frag?
2.7mm, 3.5mm and 4.00mm
What’s the difference between an LC-DCP and a DCP?
The LC-DCP has grooves underneath to reduce tissue damage to the periosteum.
Also provides biderectional compression and more stiff
What are the screws available in small frag?
2.7 cortex
2.7 locking
3.5 cortex
3.5 locking
4 cancellous
What is the drill bit and drive type for the 2.7mm cortex screw?
2.00mm drill bit and 2.5 hex drive
What is the drill bit and drive type for the 2.7mm locking screw?
2mm drill bit with a T8 stardrive
What is the drill bit and drive type for a 3.5 cortex screw?
2.5mm drill bit with a 2.5 hex
What is the drill bit and drive type for a 3.5 locking screw?
2.8 drill bit with a T15 stardrive
What is the drill bit and drive type for the 4.00mm cancellous screw?
2.5 drill bit with a 2.5 hex
What drive type to the cortex and cancellous screws use in small frag?
2.5mm hex drive
What screw should generally be used first to compress the plate to bone?
A cortex screw
What torque limiter is used for 3.5mm locking screws?
1.5Nm
What torque limiter is used with 2.7 locking screws?
.8Nm (with red on it)
What are some of the plates found in small frag?
- LCP Locking compression 3.5
- LCP One third tubular plate
- LCP Reconstruction plate 3.5
- LCP t-plate right angle 3.5
- LCP proximal humerus plate 6holehead 3.5
- LCP t plate oblique left/oblique right
What size holes do the compression plates come in in small frag?
Ranging from 5-14 (excluding 7,11,13)
