This paper presents a flexible, vision-based test setup to perform 3D measurements of thin, sheet-like structures and indentation trials to obtain geometric properties and stiffness maps of biological soft tissues. The system is utilized for in vitro testing of cartilage-bone plugs to acquire a “gold standard” which will be used to validate MRI measurements of cartilage properties.

Accurate knowledge of biomechanical characteristics of tissues is essential for developing realistic computer-based surgical simulators incorporating haptic feedback, as well as for the design of surgical robots and tools. As simulation technologies continue to be capable of modeling more complex behavior, an in vivo tissue property database is needed. Most past and current biomechanical resear...

BACKGROUND Elastic stable intramedullary nailing (ESIN) is accepted widely for treatment of diaphyseal femur fractures in children. However, complication rates of 10 to 50 % are described due to shortening or axial deviation, especially in older or heavier children. Biomechanical in vitro testing was performed to determine whether two modified osteosyntheses with end caps or a third nail could ...

STUDY DESIGN This study is a systematic review of published biomechanical studies involving pedicle screw-based posterior dynamic stabilization devices (PDS) with a special focus on kinematics and load transmission through the functional spine unit (FSU). METHODS A literature search was performed via the PubMed online database from 1990 to 2008 using the following key words: "biomechanics," "...

background patients who have shoulder pain usually have compensatory or contributory deviation of shoulder motion during arm elevation. in the traditional scapulohumeral rhythm, the share of the acromioclavicular (ac) and the sternoclavicular (sc) joint movements and also the role of ac internal rotation angle are unknown. objectives the main purpose of this study was to measure and compare the...

INTRODUCTION Extra-focal or external fixation is the method of fracture fixation through the healthy part of the bone using pins or wires. OBJECTIVE The aim was to determine which external splints (Ortofix, Mitković, Charnley and Ilizarov) had the best biomechanical properties in primary stabilization of spiral, transverse and commutative bone fractures. METHODS To determine the investigati...

Implant surface characterization and biomechanical testing were made to evaluate the effect of different surface treatments along with different implant bulk configurations expressed as biomechanical fixation at early implantation times. Three implant surfaces, namely bioactive ceramic electrodeposition (ED), alumina-blasted/acid etched (AB/AE), and resorbable blasting media (RBM) were fabricat...

Cross-links increase the stability of screw-rod systems in biomechanical testing. The aim this systemic review was to find evidence pertaining additional benefit implantation cross-links clinical practice regard different spinal diseases. Therefore, a systematic literature analysis two online databases performed according PRISMA statement. Inclusion criteria were prospective and retrospective s...

Both medial and anterolateral plate applications have been described for the treatment of distal tibia fractures, each with distinct advantages and disadvantages. The objective of this study was to compare the biomechanical properties of medial and anterolateral plating constructs used to stabilize simulated varus and valgus fracture patterns of the distal tibia. In 16 synthetic tibia models, a...
