To evaluate the clinical effectiveness of special fracture block reduction device in mininally invasive treatment for Schatzker typeⅡand Ⅲ tibial plateau fractures.

From August 2019 to now, eight patients admitted to the Department of Orthopedic Surgery of Yuebei People′s Hospital Affiliated to Shantou University who suffered from Schatzker typeⅡand Ⅲ tibial plateau fractures were included into the study, there were four cases of typeⅡand four cases of type Ⅲ.All patients were treated with special fracture block reduction device .The treatment was evaluated according to the surgical time and blood loss, and functional outcomes were evaluated according to HHS scores and Rasmussen radiological scoring system. Time to get out of bed and load was scored.

All 8 patients were followed up for 10.00-14.00 months, with an average of (11.50±1.32 ) months. Time to get out of bed and load was 5 to 8 weeks, with an average of(5.88±1.05) weeks. All the fratures healed within 10 months postoperatively.At the last follow-up, the flexion of knee joint was 95.00° to 125.00 °, with an average of (111.00±10.69)°. The satisfaction rate was 100% according to Rasmussen radiological scoring system, and the mean HHS score was 78.00 to 90.00 points, with an average of (84.25±4.89) points.

Special fracture block reduction device is tested to be a feasible and worthwhile alternative for Schatzker typeⅡand Ⅲ tibial plateau fractures.
