Clinical Effects Of Single Plate And Combined Double Plates In The Treatment Of Middle And Lower Humeral Shaft Fractures

Objective:To compare the effectiveness of the single plate and combined double plates in the treatment of middle and lower humeral shaft fractures.Methods: Fourty-nine patients with middle and lower humeral shaft fractures were treated with single or combined double plates and followed.There were 27 male and 22 female patients,aged from 22 to 76(44.47±15.53)years old,12 cases of type A,22 cases of type B and 15 cases of type C.There were 21 cases in the single plate group,including 12 males,10 females,7 cases of type A,9 cases of type B and 5 cases of type C.There were 28 cases in the combined double plates group,including 15 males,12 females,5 cases of type A,13 cases of type B and 10 cases of type C.A retrospective study was performed to compare the outcomes of two methods regarding operation time,perioperative blood loss,fracture healing time,complications and MEPS(Mayo elbow performance score).Results: Fourty-nine patients were followed with more than 12 months.There were significant differences between the two groups in the number of internal fixation failure and Mayo elbow score(P<0.05).However,perioperative blood loss,the operative time,the fracture healing time and number of radial nerve injury had no differences(P>0.05).Conclusion :In treatment of the middle and lower humeral shaft fractures,the combined double plates fixation have better affected limb function and more remarkable the operation effect than the single plate fixation.
