RISThe Effect of Screw Pullout Rate on Screw Purchase in Synthetic Cancellous Bone
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Clinically, orthopaedic fracture fixation constructs are mounted using screws inserted into cancellous bone, while biomechanical studies are increasingly using commercially available synthetic bones. ...
Cortical Screw Pullout Strength and Effective Shear Stress in Synthetic Third Generation Composite Femurs
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Background: The use of artificial bone analogs in biomechanical testing of orthopaedic fracture fixation devices has increased, particularly due to the recent development of commercially available ...
Cortical Screw Purchase in Synthetic and Human Femurs
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Biomechanical investigations of orthopedic fracture fixation constructs increasingly use analogs like the third and fourth generation composite femurs. However, no study has directly compared cortical ...
The Biomechanical Effect of Torsion on Humeral Shaft Repair Techniques for Completed Pathological Fractures
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In the presence of a tumor defect, completed humeral shaft fractures continue to be a major surgical challenge since there is no “gold standard” treatment. This is due, in part, to the fact ...
The Biomechanical Consequence of Insufficient Femoral Component Lateralization and Exposed Cancellous Bone in Hip Resurfacing Arthroplasty
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Insufficient lateralization of the femoral component coupled with exposed reamed cancellous bone has been speculated to predispose to femoral neck fracture. The current study examined the effect ...
A Preliminary Biomechanical Assessment of a Polymer Composite Hip Implant Using an Infrared Thermography Technique Validated by Strain Gage Measurements
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: With the resurgence of composite materials in orthopaedic applications, a rigorous assessment of stress is needed to predict any failure of bone-implant systems. For current biomechanics research, ...
Biomechanical Measurements of Torsion-Tension Coupling in Human Cadaveric Femurs
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The mechanical behavior of human femurs has been described in the literature with regard to torsion and tension but only as independent measurements. However, in this study, human femurs were ...
A Biomechanical and Finite Element Analysis of Femoral Neck Notching During Hip Resurfacing
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Hip resurfacing is an alternative to total hip arthroplasty in which the femoral head surface is replaced with a metallic shell, thus preserving most of the proximal femoral bone stock. ...
Biomechanical Measurements of Surgical Drilling Force and Torque in Human Versus Artificial Femurs
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Few experimental studies have examined surgical drilling in human bone, and no studies have inquired into this aspect for a popular commercially-available artificial bone used in biomechanical ...
Linear and Torsional Mechanical Characteristics of Intact and Reconstructed Scapholunate Ligaments
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The mechanical behavior of human scapholunate ligaments is not well understood. Presently, intact scapholunate specimens were mechanically tested in linear distraction and torsion. Fresh bovine ...
