ABSTRACT

Objective To compare the clinical effect of dynamic compression plate (DCP) and limited contact dynamic compression plate (LC-DCP) fixation in the treatment of limbs long bone fracture,provide certain basis for the choice of clinical internal fixation.Methods The clinical data of 172 patients with limbs long bone fracture treated with DCP and LC-DCP fixation were retrospectively analyzed.One hundred and one cases in LC-DCP group,and 71 cases in DCP group,the operation time,intraoperative blood loss,hospitalization time,fracture healing time,incidence of nonunion,daily activity ability and joint function score and clinical curative effect in two groups were compared.Results The operation time,fracture healing time,incidence of nonunion in LC-DCP group were better than those in DCP group[(62 ± 13) min vs.(88 ±20) min,(60.0 ± 20.5) d vs.(85.0 ± 25.5) d,1.0％ (1/101) vs.7.0％ (5/71)],there were significant differences (P ＜ 0.05),but the intraoperative blood loss and hospitalization time between two groups had no significant difference (P ＞ 0.05).Barthel and Harris score in LC-DCP group were better than those in DCP group [(72.61 ± 8.63) scores vs.(52.58 ± 5.53) scores,(69.28 ± 7.63) scores vs.(55.07 ± 6.26) scores],there were significant differences (P ＜ 0.05).The excellent rate in LC-DCP group was better than that in DCP group [99.0％ (100/101) vs.90.1％ (64/71)],there was significant difference (x2 =15.71,P ＜ 0.01).Conclusion Limbs long bone fracture treat with LC-DCP,can improve clinical curative effect and reduce complications,improve the daily ability of joint function in patients and is worth using in clinic.
