How does a locking compression plate work?
A locking plate does not have to precisely contact the underlying bone in all areas. When screws are tightened, they “lock” to the threaded screw holes of the plate, stabilizing the segments without pulling the bone to the plate. Locking screws make it impossible for screw insertion to alter the reduction.
When should you lock your plates?
The indications for use of locking plates include the following: (1) metaphyseal and intra-articular fractures; (2) highly comminuted fractures, particularly those involving diaphyseal and metaphyseal bone; (3) osteoporotic bone; (4) proximal tibia and distal femur fractures; and (5) periprosthetic fractures.
What is a locked plate?
Locking plates are fracture fixation devices with threaded screw holes, which allow screws to thread to the plate and function as a fixed-angle device 1 – 3. These plates may have a mixture of holes that allow placement of both locking and traditional nonlocking screws (so-called combi plates) 4 , 5.
What contributes to stiffness of locking plate?
It has been shown that the main factors affecting the stiffness of LCP include working length, number of screws, distance from the plate to the bone, and length of the plates ; while construct stiffness is greatly affected by the fracture gap .
What is LCP in Ortho?
Locking compression plate (LCP) has conventionally been the most extensively employed plate in internal fixation bone implants used in orthopaedic applications. LCP is usually made up of non-biodegradable materials that have a higher mechanical capability.
What are LCP plates?
The Locking Compression Plate (LCP) is a new screw-plate system that offers the possibility of inserting conventional and locking head screws into the specially designed combination holes. It represents a further development of the PC-Fix and the LISS and was released for clinical application in March 2000.
What is LCP in surgery?
The Locking Compression Plate (LCP) Combining Conventional and Locked Plating Techniques. The combination of conventional compression plating and locked plating techniques enhances plate osteosynthesis.
What is DCS Ortho?
The DCS is a versatile plate which can be applied in a bridging mode (fragmentary supracondylar fracture component) and with compression (simple supracondylar fracture component). Any fractures of the articular block are first addressed under direct vision using standard techniques of interfragmentary compression.
How is CRIF done?
CRIF is a surgery. Your healthcare provider moves the broken bones in your leg, ankle, or foot into correct position. He or she is able to do this without an incision being made over the break. Pins and wires are used to hold the pieces of bone in place.
What are ORIF plates made of?
How Is ORIF Surgery Performed? During the surgery, your bone fragments will be repositioned into normal alignment. The bone fragments are held together with hardware such as plates, screws, or wires. The implants are made from stainless steel or titanium because these are strong and durable metals.
What is a Locking Compression Plate (LCP)?
The Locking Compression Plate (LCP) system offers a number of advantages in fracture fixation combining angular stability through the use of locking screws with traditional fixation techniques. This makes the implant particularly suitable for use in poor bone stock and complex joint fractures, especially in the epimetaphyseal area.
What are the advantages of a locking plate/screw system?
There are several advantages to a locking plate/screw system: A locking plate does not have to precisely contact the underlying bone in all areas. When screws are tightened, they “lock” to the threaded screw holes of the plate, stabilizing the segments without pulling the bone to the plate.
How does the locking plate work?
The locking plate has a corresponding threaded plate hole. During insertion the locking head screw engages and locks into the threaded plate hole.
What is the purpose of a locking reconstruction plate?
The plate and screws provide adequate rigidity and do not depend on the underlying bone (load bearing osteosynthesis) when using a locking reconstruction plate 2.4. On each side of the fracture, the screws are locked into the plate as well as into the bone.
