Objective: to explore the locking plate external treatment of clavicle, foot radius, tibiofibula fracture treatment of clinical efficacy. Methods: select 64 cases whose patients have fracture of collarbone, radius and ulna, or tibiofibula in our hospital from January, 2014 to May, 2014 as the research object. Take the comparison research method and divide the patients into comparison group and observation group; each group has 32 cases; the comparison group treats with locking plate internal regular treatment, the observation group takes the locking plate external treatment. compare two groups of patients after treatment of each index and explore the locking plate external in clavicle, foot radius, the clinical application value of tibiofibula fractures. Results: observation group’s incision length, intraoperative blood loss, operating time, and fracture healing time data associates with the control group difference was statistically significant (P
