Purpose: To evaluate the use of locked Compression Plate (L.C.P.) in metaphyseal long bones fractures, and report our preliminary results.

Materials and Methods: 23 patients 14–82 years old with long bones metaphyseal fractures underwent surgery with the use of L.C.P. between January 2004 and August 2004. Four patients were adolescents.

7 patients had Supracondylar femoral fracture. One of them had the fracture at the tip of IMN. 11 patients had distal Tibia, one had proximal+midshaft tibia and 4 had distal humerus fractures. All plates were prebended to fit the area of the fracture using a skeleton model. The plates were inserted percutaneously with reduction of the fracture.

Partial weight bearing started after 6 weeks and full weight bearing started after 12 weeks.

Results: Unuion was seen in x-ray after 6 to 12 week in 95% of patients. 20 patients regained full range of motion of the adjacent joints at 3 months follow-up.

Complications: One patient developed compartment Syndrome in a high energy tibial fracture. One patient developed deep infection at the site of fibular plate not affecting the L.C.P. at the tibia. One patient developed temporary weakness of extensor Hallucis longus.

Conclusions: L.C.P. proved to be effective in fixation of meta-epiphyseal zones which are difficult in IMN fixation. The use of this plate enables fixation of long bones in adolescents with open growth plate. The locking system enables good fixation of osteoporotic bones and in periprosthetic fracture. The high primary stability in combination with newly developed minimal-invasive techniques (MIPO = minimal invasive plate osteosynthesis) are the bases for a rapid bony consolidation, a low complication rate and good functional results.
