Abstract: Objective    To investigate the effect of the suture Nice knot tension band combined with lag screw fixation for simple transverse olecranon fracture.    Methods    From January 2016 to December 2020, 23 cases of simple transverse olecranon fracture were fixed with suture Nice knot tension band and lag screw. There were 14 cases of Mayo type IIA and Mayo 3 cases of type IIIA , as well as 6 cases of olecranon transverse osteotomy for comminuted fracture of intercondylar humerus. Elbow flexion and extension motion were started on the second day after operation. The fracture healing, limb function recovery and complications were recorded.   Results  All patients were followed up for 12 to 28 months, with an average follow-up of (17.5±2.7) months. There were no screw breakage and obvious discomfort caused by screw withdrawal stimulation. All the fractures healed, the average healing time was (2.3±0.5) months. At 3 months and 1 year postoperatively, the average flexion and extension range of elbow joint were (103.5±22.0) ° and (127.1±34.0) °, respectively. The average pronation range were (72.2±7.0) ° and (80.8±7.5) °, respectively. The average supination range were (70.9±6.7) °and (78.2±8.0) °,There were statistical difference between before operation and 3 months and 1 year  after operation (P<0.05). At the last follow-up, the Mayo elbow performance score averaged was (87.7±8.3), the excellent and good rate was 91.3%, the removal rate of internal fixation was 26.1%, of which, the required removal rate of internal fixation was 4.35%.    Conclusions    Suture Nice knot tension band and lag screw fixation for simple transverse olecranon fracture has the advantages of simple performance, rapid and satisfactory functional recovery of elbow joint, lest complications and lower removal rate of internal fixation.
