The efficacy of tibial shaft fractures treated with interlocking nails / 中国医师进修杂志

ABSTRACT

Objective To investigate the difference of efficacy of interlocking nails and dynamic compression plate in tibial shaft fractures.Methods The clinical data of 137 cases with tibial shaft fractures were reviewed retrospectively.They were divided into two groups according to the various treatments which included interlocking nails group(72 cases with 79 fractures) and dynamic compression plate group(65 cases with 70 fractures).The efficacy,healing fineness rate,function score after operation and complications were compared.Results After operation,the patients were followed up 21.4 months on average.The postoperative callus time,weight-bearing limb time,healing time and postoperative fixation time taken in interlocking nails group was shorter than that in dynamic compression plate group [(2.36 ± 0.46) months vs.(3.12 ± 0.57) months,(2.42 ± 0.51) months vs.(3.14 ± 0.63) months,(7.65 ± 1.29) months vs.(9.33 ±1.54) months,(12.64 ± 3.76) months vs.(16.38 ± 3.15) months],and there was significant difference (P＜ 0.05).The healing fineness rate was 97.5％(77/79) in interlocking nails group,and 92.9％(65/70) in dynamic compression plate group,and there was nosignificant difference (x2 =1.76,P ＞0.05).The incidence of comphcations in interlocking nails group was higher than that in dynamic compression plate group[25％(2H9) vs.12.9％(9H0)],and there was significant difference(P ＜ 0.05).Condmions Interlocking nails have better biomechanical features with high union rate,low infective rate and good recovery of joint function.The clinical result of interlocking nails for the tibial shaft fractures is also better than that of dynamic compression plate.
