One-stage minimally invasive surgery for femoral and ipsilateral tibial plateau fractures with a rapid reductor / 中华创伤骨科杂志

ABSTRACT

Objective To investigate the fixation sequence,key points and clinical value of a new minimally invasive surgery for one-stage treatment of femoral and ipsilateral tibial plateau fractures with a rapid reductor.Methods From October 2015 to January 2017,5 patients with femoral and ipsilateral tibial plateau fractures received surgery at our department.They were 4 men and one woman,aged from 23 to 65 years (mean,45.5 years).The femoral fractures were type A in 2 cases,type B in 2 cases and type C in one case according to AO/OTA classification.The tibial plateau fractures were type Ⅴ in 2 cases and type Ⅵ in 3 according to Schatzker classification.After the tibial plateau fractures were first fixated,Kirschner wires were inserted via the femoral condyle and distal tibia.A rapid reductor was used to reduce the tibial plateau and dual plates were implanted by percutaneous minimally invasive internal fixation.Then the same set of rapid reductor was used to treat femoral fractures by antegrade femoral nailing.The bone traction was completed via the femoral condyle and anterior superior iliac spine.The operative time,bone union time,knee functional recovery and hospital stay were recorded.Results The 5 patients were followed up for an average of 10 months (from 7 to 17 months).No delayed union,nonunion or malunion happened of either femoral or tibial plateau fractures.The healing time for femoral fractures ranged from 4 to 8 months,averaging 5.5 months;the union time for tibial plateau fractures ranged from 10 to 14 weeks,averaging 12.0 weeks.The knee flexion averaged 110° (from 95° to 130°).The overall functional recovery was rated as excellent in 2 cases and good in 3 according to the Karlstr(o)m & Olerud criteria.The average hospital stay was 18 days(from 13 to 32 days).Conclusion Minimally invasive surgery with a rapid reductor can treat femoral and ipsilateral tibial plateau fractures at one stage,leading to fine functional recovery of the knee and greatly reduced hospital stay in particular.
