BACKGROUND Fixation of radial neck fractures can be achieved with a plate and screw construct or with two screws. This study evaluated the biomechanical properties of three different fixation methods following radial neck fractures. METHODS Twenty-four fourth-generation composite radii were sawed to simulate an unstable radial neck fracture. They were then instrumented with a plate and screw ...

BACKGROUND The management of periprosthetic femoral fractures after total hip and knee replacement remains difficult and controversial. This study was performed to determine the results of Mennen plate fixation for the treatment of periprosthetic femoral fractures. METHODS This retrospective multicenter study consists of a review of a consecutive series of thirty-five patients in whom a total...

An ideal bone plate for internal fixation of bone fractures should have good biomechanical properties and biocompatibility. In this study, we prepared a new nondegradable bone plate composed of a ternary nano-hydroxyapatite/polyamide 66/glass fiber (n-HA/PA66/GF) composite. A breakage area on the n-HA/PA66/GF plate surface was characterized by scanning electron microscopy. Its mechanical proper...

doi:10.3415/VCOT-12-12-0154 Our first issue of VCOT for this year contains several papers pertaining to the study of fracture morphology, and the stabilization of fractures with bone plates (1-3). In addition, Herten and colleagues describe the characterization of mesenchymal stem cells isolated from bone marrow by a point-of-care device; these cells had osteogenic potential that could be expec...

We present a rare clinical case of a 90-year-old female who sustained a proximal femoral neck fracture following long-standing hip arthrodesis. Since the fracture occurred relatively proximally and involved the pelvis, double-plate fixation was chosen to achieve rigid fixation. The reconstruction plate was placed at the posterior and anterior columns individually through single vertical incisio...

A 22-year-old man was hospitalized with a sternoclavicular joint (SCJ) dislocation caused by a traffic accident. Surgical reduction and fixation of the SCJ were performed using a T-plate. SCJ dislocation is rare, accounting for less than 1% of all dislocations, and is usually treated conservatively, although severe cases may require surgery. Surgery typically involves joint reduction and fixati...

Distal humeral fractures in adults are relatively uncommon injuries that require operative intervention in the majority of cases. Dual plate fixation, with placement of a separate strong plate on each column and orientation of the plates either at 90° or 180° to each other, is indicated for all adult fractures involving both columns of the distal part of the humerus. Acute total elbow arthropla...

We used decision-analysis modeling to determine the most cost-effective fixation device among Herbert screws, AO screws, and the Luhr plate for first metatarsophalangeal joint arthrodesis. The model considered patient-reported outcomes at minimum 2-year follow-up, patient charges for the entire course of care, and event and outcome incidences within each fixation group. AO screws had the lowest...

OBJECTIVES Uniaxial, first-generation locking plates have become increasingly popular for fixation of supracondylar femur fractures. Polyaxial plates are currently available, which allow for variable-angle screw insertion; however, the biomechanical integrity of these new locking constructs is yet unproven. This study compares the mechanical stability of a conventional locking plate with that o...
