ABSTRACT

Objective To study the methods and clinical effect of lateral less invasive stabilization system(LISS)plate combined with medial buttress plate in distal femoral fractures patients with comminuted medial cortex.Methods The clinical data of 25 distal femoral fractures patients with comminuted medial cortex from June 2014 to December 2015 were retrospectively analyzed, and all patients were treated with lateral LISS plate combined with medial buttress plate. According to the AO fracture classification,A3 type was in 10 cases,C2 type was in 9 cases,and C3 type was in 6 cases.The knee joint function at 3,6 and 12 months after operation was evaluated according to American hospital for special surgery (HSS) knee joint function score, and the clinical effect was evaluated 12 months after operation.Results The patients were followed up 18-36 months,with an average of 23.4 months.The operation time was (80 ± 22) min, intraoperative bleeding was (395 ± 56) ml, and the average hospitalization time after operation was 5.6 d.All patients got bone union,and the bone union time was 16-30 months,with an average of 18.7 months.All patients had no incision infection,no fracture and delayed union.The HSS knee joint function scores at 3,6 and 12 months were(84.3 ± 7.8),(89.3 ± 7.2) and(97.9 ± 4.3)scores.The incidence of complications was 24%(6/25),and the excellent and good rate was 84%(21/25).Patients felt satisfied.Conclusions The clinical effect of lateral LISS plate combined with medial buttress plate in distal femoral fractures patients with comminuted medial cortex is good.
