Fatigue strength of common tibial intramedullary nail distal locking screws
BACKGROUND Premature failure of either the nail and/or locking screws with unstable fracture patterns may lead to angulation, shortening, malunion, and IM nail migration. Up to thirty percent of all unreamed nail locking screws can break after initial weight bearing is allowed at 8-10 weeks if union has not occurred. The primary problem this presents is hardware removal during revision surgery....
متن کاملDistal Locking Screws for Intramedullary Nailing of Tibial Fractures.
Recently introduced tibial intramedullary nails allow a number of distal screws to be used to reduce the incidence of malalignment and loss of fixation of distal metaphyseal fractures. However, the number of screws and the type of screw configuration to be used remains obscure. This biomechanical study was performed to address this question. Thirty-six Expert tibial nails (Synthes, Oberdorf, Sw...
متن کاملThe Role of Biplanar Distal Locking in Intramedullary Nailing of Tibial Shaft Fractures
Background: To compare the union times of the uncomplicated tibial shaft fractures, which were distally locked by twocoronal and one sagittal screws and by only two coronal screws.Methods: 45 patients with tibial shaft treated with intramedullary nailing included in this study. 23 of 45 fractureswere treated with uniplanar two distal interlocking (Group 1) and 22 fractures were treated with bip...

متن کاملBiomechanical comparison of distal locking screws for distal tibia fracture intramedullary nailing
Background: Newer generation intramedullary (IM) tibial nails provide several distal interlocking screw options. The objectives were to determine: 1) if the new oblique interlocking option provides superior stability, 2) which screw orientation/ configuration is the most biomechanically stable, and 3) if three distal interlocking screws provide better stability. Methods: A preliminary experimen...
