LC-DCP is the latest plate and screw system developed by AO-ASIF group. There are many merits of LC-DCP with its unique contour and material. : Reduction of surface contact between plate and bone result in preserved vascularization and then improved bone consolidation. Compression can be achieved in either longitudinal direction and a lag screw can be inserted at greater inclination. In addition, pure titanium as an LC-DCP material display optimal biocompatibility and reduce the spread of bacteria and increase resistance against infection. Between June 1994 and September 1995, 39 patients with 40 long bone fractures were treated using LC-DCP.(24 femur, 13 humerus, 3 tibia) Follow-up averaged 12 months : Bone union was achieved in 32 cases(80%) The complications were 7 cases of metal failure, 7 cases of limited joint motion, 2 cases of nonunion,2 cases of delayed union and 2 cases of deep infection.
