2. • Plating of fractures began in 1895 when Lane first introduced a metal
plate for use in internal fixation.
• Lambotte in 1909 and then Sherman in 1912 introduced their
versions of the internal fracture fixation plate
in 1949 denis was 1st surgon to use
intrafragmentry compression achived
by achieved by tightening the
side screw
3. • since 1958 AO has devised a family of plates for long bone fracture
starting with round hole plates
• in 1969 DCP was developed
• in 1994 LC DCP was created
• in 2011 LCP with combination holes has came in to use
4. plates are like internal splints holding fractured end of bone
It has two mechanical function
1 transmit force from one end of bone to other bypassing the area of fracture
2 holding fracture fragment in proper alignment throughout healing process
5. • Goals:
• – Restoration of bony anatomy while respecting soft tissues
• – Stable fixation
• – Accelerated recovery
• – More predictable and potentially faster healing
• • Indications:
• – Displaced intra-articular fractures
• – Open fracture
• – Polytrauma
• – Associated neurovascular injury
• – Failure of closed treatment
16. Conventional and locking head screws can be used in the
same fracture fragment but this requires caution and
careful planning.
Once a locking head screw has been inserted into fracture
fragment, no (additional) conventional screws should be in-
serted into this side the fixation:
Only additional locking head screws may be used.
18. Failure of fixation with traditional plates starts at one screw due to toggle during loading which
may propogate to other screw .
similar phenomenpn dose not occure with locked plates due to load distributed more evenly
