Unicortical versus bicortical locked plate fixation in midshaft clavicle fractures.
Higher rates of poor outcomes in displaced midshaft clavicle fractures treated nonoperatively have recently been reported. Along with expanding indications for operative fixation and increasing application of locked plate constructs, it is unknown whether complications related to bicortical penetration of the clavicle can be avoided using unicortical fixation. The purpose of this study is to co...
متن کاملBiomechanical comparison of bicortical versus unicortical screw placement of proximal tibia locking plates: a cadaveric model.
OBJECTIVE The purpose of this study was to compare the biomechanical properties of bicortical with unicortical screws in a proximal tibial fracture cadaveric model. SETTING Biomechanics laboratory at a Level 1 trauma center. PATIENTS/PARTICIPANTS Eight pairs (4 male and 4 female) of elderly (average age, 79 years; range, 63 to 104 years) cadaveric tibiae. INTERVENTION Osteotomies were per...
متن کاملA biomechanical study comparing plate fixation using unicortical and bicortical screws in transverse metacarpal fracture models subjected to cyclic loading.
The use of bicortical screws to fix metacarpal fractures has been suggested to provide no added biomechanical advantage over unicortical screw fixation. However, this was only demonstrated in static loading regimes, which may not be representative of biological conditions. The present study was done to determine whether similar outcomes are obtained when cyclic loading is applied. Transverse mi...
متن کاملBiomechanical Comparison of Bicortical, Unicortical, and Unicortical Far-Cortex-Abutting Screw Fixations in Plated Comminuted Midshaft Clavicle Fractures.
PURPOSE The objective of this study was to assess the biomechanical properties of bicortical locking screws, unicortical locking screws, and unicortical far-cortex-abutting locking screw fixation in a cadaver model of comminuted midshaft clavicle fractures stabilized with a locking plate placed on the superior surface of the clavicle. METHODS Nine pairs of adult fresh-frozen cadaver clavicles...
متن کاملBiomechanical Evaluation of Anterior Cervical Spine Fixation Devices
The anterior cervical plate fixation systems have been widely used in treatment of complex spinal disorders such as traumatic lesion, disc hernination, tumor, spondylosis, arthritides, and others. Combined with bone graft or other fusion techniques the satisfactory outcomes were higher than 88% (Clements 1990, Naito 1993,Bose 1998, Schneeberger 1999). Among the screw plate fixation systems, Cas...
