Biomechanical evaluation of fixation techniques for bridging segmental mandibular defects.
OBJECTIVE To compare biomechanical properties of currently available plating systems used to reconstruct segmental mandibular defects. DESIGN Controlled in vitro investigation. SETTING Academic medical center laboratory. INTERVENTIONS Thirty-two polyurethane mandibles were equally divided among 4 groups: mandibles with a 4-cm lateral segmental defect that was bridged with a (1) 3.0-mm loc...
متن کاملBiomechanical analysis of occipitocervical stability afforded by three fixation techniques.
BACKGROUND CONTEXT Occipital condyle screws appear to be a novel technique that demands biomechanical consideration. It has the potential to achieve fixation anterior to the axis of rotation while offering a point of fixation in line with the C1/C2 screws. PURPOSE To compare the segmental stability and range of motion (ROM) of standard occipitocervical (OC) screw/rod and plate constructs vers...
متن کاملCoronal fractures of the distal femoral condyle: a biomechanical evaluation of four internal fixation constructs.
This study evaluated different fixation methods in posterior femoral condyle coronal fractures. A standardised osteotomy was created in synthetic composite femurs and fixed with one of four methods (one 3.5 mm diameter screw, two 3.5 mm screws, one 6.5 mm screw, two 6.5 mm screws). The stiffness and mean loads to specified displacements were measured. The stiffness of two 6.5 mm screws was sign...
متن کاملOccipitocervical fixation using occipital bone hooks and cervical lateral mass screws: analysis of 16 cases.
AIM We present a series of 16 patients who underwent occipitocervical fixation with occipital bone hooks used as a substitute for occipital screws for the treatment of occipitocervical instability. MATERIAL AND METHODS In this technique; instrumentation was started following the decompression with insertion of screws into lateral masses. At the occipital level, two symmetrical burr holes were...
متن کاملOccipital Condyle Fractures
RECOMMENDATIONS DIAGNOSTIC: Standards: There is insufficient evidence to support diagnostic standards. Guidelines: Computed tomographic imaging is recommended for establishing the diagnosis of occipital condyle fractures. Clinical suspicion should be raised by the presence of one or more of the following criteria: blunt trauma patients sustaining high-energy craniocervical injuries, altered con...
