Patella fractures treated with cannulated lag screws and fiberwire have a high union rate and low rate of implant removal
Injury Nov 13, 2019
Busel G, Barrick B, Auston D, et al. - Researchers sought to describe the outcomes of open reduction internal fixation of patella fractures using cannulated lag screws and FiberWire with regard to union and symptomatic implant removal. From prospectively collected database, they identified 387 consecutive patients; of these 50 fractures were included in the final analysis. Outcomes support the potential value of using cannulated lag screws and FiberWire for treating patella fractures with a high rate of primary union (96%) and a low rate of symptomatic implant removal (8%). The implant removal rate compares favorably with alternative constructs, with an equivalent rate of fracture union. They identified hardware irritation as a major cause of reoperation in the fixation of patella fractures. A powerful adjunct to the screw fixation of the transverse patella fracture is suture cerclage with no increased rate in hardware irritation. This resulted in lower levels of hardware removal. With the utilization of the suture cerclage in the treatment of transverse patella fractures, a high union rate is expected.
