Observation Effect on Modified Kirschner Wire and Tension Band Fixation for the Treatment of A Type and B 2 Type Hand to Bone Fracture

Objective To explore the clinical effect on modified Kirschner wire and tension band fixation for the treatment of A type and B 2 type of metacarpal shaft fracture. Methods Selected 100 cases with type A and type B 2 of metacarpal fractures from June 2010 to June 2013 in our hospital. According to the order number was divided into control group and observation group,each group of 50 cases. The control group used the traditional Kirschner wire and tension band fixation treatment,observation group were treated with modified Kirschner wire and tension band fixation. Observations two groups of fracture healing time and the incidence of complications. Results All patients were followed up for 3 to 12 months,In observation group,the fracture healing time was(4.5 ±1.6)weeks,shorter than that of control group(8.2±1.4)weeks; In the control group,7 cases(14%) were delayed union and 6 cases(12%) were infected. In the observation group,1 cases(2%) were delayed union and 5 cases(10%) were infected. The incidence of complication in observation group was lower than that in control group,P0.05,had difference statistically significance. Conclusion The modified Kirschner wire and tension band fixation for type A and type B 2 can promote the healing of the fracture of metacarpal shaft fracture,reduce the postoperative complications,curative effect.
