Objective:
To prospectively evaluate the clinical result of Cable-Pin system in the treatment of olecranon fractures and compare with tension band wiring (TBW) method.
Methods:
From March 2008 to June 2010,65 patients with olecranon fractures were divided into two groups: 32 patients in Cable-Pin group were treated with Cable-Pin system, including 18 males and 14 females, ranging in age from 21 to 69 years, with an average of (53.69 +/- 13.42) years; 33 patients in TBW group were treated with Kirschner tension bend, including 20 males and 13 females, ranging in age from 20 to 70 years, with an average of (53.18 +/- 13.36) years. The incision length, operation time, the amounts of hemoglobin after operation, fracture healing time, complications and HSS elbow scores were recorded and analyzed statistically. The follow-up period ranged from 12 to 24 months, with an average period of 18.4 months.
Results:
There were statistical differences (P<0.05) in fracture healing time (t= 2.588, P=0.012), complication rate (chi2=4.534, P=0.033) and HSS elbow joint scores (Z=-2.039, P=0.041) between two groups, which all were superior to TBW in Cable-Pin group. There was no statistical differences (P>0.05) in the length of incision (t= 0.416, P=0.679), operation time (t=0.816, P=0.417) and the postoperative amounts of hemoglobin (t=-0.553, P=0.294) between two groups.
Conclusion:
Cable-Pin system is an easy and reliable method for the treatment of olecranon fractures with less complications and better functions than TBW.
