OBJECTIVE: To summarize literature on clinic research of locking compression plate (LCP) on fracture of distal radius, proximal humeral fracture, tibia fracture and other fracture.DATA SOURCE: The first author retrieved literatures from PubMed database (http://www.ncbi.nlm.nih.gov/PubMed and CNKI database (www.cnki.net/index.htm) published between June 1992 and May 2009 with the key words of "LCP, Fracture, Therapy,Review".DATA SELECTION: Inclusion criteria: cases undergoing LCP internal fixation; clinical of LCP internal fixation. Repetitive studies were excluded.MAIN OUTCOME MEASURES: A total of 127 literatures were selected and primarily collected by reading titles and abstract. A total of 51 literatures unrelated to study objective, and 35 studies of repetitive contents were excluded. Finally, 41 literatures were included for analysis, containing review, commentary, treatise and clinical report.RESULTS: LCP internal fixation was applied in clinical broadly in recent years. Therapeutic efficacy was significantly better than common internal fixation system. LCP internal fixation depended on minimal invasion LCP internal fixation, with characteristics of small wound, simple operation, stable internal fixation and fracture anatomical reduction. It could replace external fixation to some extents. The stability was bigger compared with the external fixation. However, intramedullary pin fixation should be firstly selected for lower limb cadre fracture. There were few studies on this aspect. Controlled studies should be performed in the future.CONCLUSION: LCP was invented as a new technology which was transition from mechanics of machinery to biomechanics. The method makes good contribution to orthopaedics by advocating elasticity, reducing hurt and promoting callus.
