Modified Tension band& longitudinal K .wires fixation versus Circumferential Cerculage wire in treatment of patellar Fractures.

Abstract

Fracture of patella comprises approximately 1% of all skeletal injuries. We managed 32 patients with closed transverse patellar fractures in a prospective study during the period between November 2006 and December 2008(with mean follow up one year) at al Sader, al Hakeem and al Manathera hospitals .All cases were treated by open reduction and internal fixation. There were 16 cases randomly fixed by modified tension band and longitudinal Kirschner wires (MTB&LKW) method and 16 randomly fixed by circumferential cerculage wire (CCW) in patients' age (20-50 years). The results were assessed by a Lysholm & Gillquist score. Regarding (MTB&LKW) method, the outcome was excellent in 50%, good in 37, 5 %, and fair in 12,5%case but the outcome was excellent in31,75%,good in25%, fair in 25% and poor in 18,25 % with (CCW) method. We concluded that the (MTB&LKW) fixation method is superior to (CCW) method in that it shortens the average time for union and allowed less fracture displacement than did other method. The aim of the study is to determine whether modified tension band fixation method results in better outcomes compared with those after circumferential Cerculage wire fixation method in the treatment of closed patellar fractures.
