title: [Case-control study on cable-pin system in the treatment of olecranon fractures].
abstract: 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.
  
  
  CONCLUSIONS
  Cable-Pin system is an easy and reliable method for the treatment of olecranon fractures with less complications and better functions than TBW.
