Objective: To compare and discuss the clinical effect and biomechanics between locking compression plate and interlocking intramedullary nail for treatment of humerus shaft fracture.
Methods: 112 cases of patients with humerus shaft fracture were selected and divided into the locking compression plate group (LCP group) with 58 patients and the interlocking intramedullary nail group (IIN group) with 54 patients. The different operation time, bleeding volume, the length of stay after operation, healing time, difference of complication and shoulder joint dysfunction were made a comparison between the LCP group and IIN group.
Results: The operation time of patients in IIN group was (77.17 ± 15.46) min, which was shorter than that of LCP group (97.20 ± 30.06) min, p<0.05; the bleeding volume of patients in IIN group was (110.59 ± 50.34) ml, which was significantly less than that in LCP group, p<0.01. Besides, in IIN group there were 4 patients (7.41%) with the acromion injury, which was not seen in LCP group (p<0.05). However, in IIN group there were 6 patients (11.11%) with the radial nerve palsy, which was not seen in IIN group (p<0.05). Compared with patients in IIN group, the recovery of shoulder joint function was due to the plate (p<0.05).
Conclusion: The operation time, intraoperative blood loss, and the rate of radial nerve palsy of patients in IIN group are superior to these in LCP group, which is more aligned with modern orthopaedic advocated by the “Biological Osteosynthesis” principle.Author(s): He ShengWei, Qinruixian, Li Bin, Du Guangyu, Sun Chuanxiu, Sun Xuegang, Binzhi Chen
