Minimally invasive reduction and fixation for fractures of tibial intercondylar spine with Zhang's reduction device / 中华创伤骨科杂志

ABSTRACT

Objective To discuss the clinical effects of minimally invasive reduction and fixation with Zhang's reduction device for fractures of tibial intercondylar spine.Methods Five patients with tibial intercondylar spine fracture underwent treatment and reduction with Zhang's reduction device from December 2018 to February 2019 at Orthopedic Trauma Center,The Third Hospital of Hebei Medical University.They were 3 men and 2 women,aged from 25 to 56 years (average,43 years).The left side was affected in 2 cases and the right side in 3.By the Meyers classification,there were 2 cases of type Ⅱ and 3 ones of type Ⅲ.All the patients underwent the same surgical procedures and postoperative treatment.Their operation time,amount of bleeding,number of fluoroscopy required for insertion of guide pin,postoperative complications,fracture healing and knee joint range of motion at the last follow-up were recorded.Results The operation time for the 5 patients averaged 50.0 min,amount of bleeding 23.0 mL,and number of fluoroscopy required for insertion of guide pin 12.6 times.Their knee joint range of motion at the last follow-up ranged from 0° to 136.0°.All the incisions obtained primary union with no infection.Their hospitalization time ranged from 7 to 15 d (average,10.5 d).They obtained an average follow-up of 4.3 months (from 2 to 6months).All the fractures achieved union with no malunion,nonunion or refracture.Conclusions The minimally invasive reduction and fixation with Zhang's reduction device for fractures of tibial intercondylar spine can lead to satisfactory clinical effects.It is less invasive than open reduction and simpler than arthroscopic surgery so that it is more appropriate to be popularized in primary hospitals.However,this method has not been widely applied in clinic and more clinical trials are needed.
