Patella fractures treated with cannulated lag screws and fiberwire have a high union rate and low rate of implant removal
Injury Oct 05, 2019
Busel G, Barrick B, Auston D, et al. - The results of open reduction internal fixation of patella fractures (OTA 34 A-C) using cannulated lag screws and FiberWire (Arthrex, Naples, FL, USA) with regard to union and symptomatic implant removal were reported via performing retrospective review of prospectively collected database. From urban level 1 trauma center and level 2 trauma center, researchers obtained data of 387 patients with displaced intra-articular patella fractures (OTA 34 A-C) treated with ORIF by cannulated lag screws and FiberWire tension band/cerclage between January 1, 2009, and August 1, 2018; Average age was 57.7 years (range 21-86) and average follow up period was 20.6 months (range 6-98 months). The average time to clinical and radiographic union was 3.1 months (range 3-7 months). Outcomes revealed a high rate of primary union (96%) and a low rate of symptomatic implant removal (8%) in correlation with the treatment of patella fractures using cannulated lag screws and FiberWire. With an equivalent rate of fracture union, the implant removal rate compares favorably with alternative constructs.
