Abstract Numerous biomechanical studies using osteoarticular complex need frozen cadaveric specimens. Some of these studies deal with the resistance of the tendinous structures, for example the resistance of some autografts, such as the patellar ligament and the semitendinosus and gracilis tendons for reconstruction of the anterior cruciate ligament. The(More)
Our aim was to build and assess a static mandibular simulator capable of reproducing various masticatory exercises as closely as possible to physiological situations. Unlike existing devices that reproduce a small number of exercises and of muscular bundles, our simulator is able to reproduce all types of effort in the sagittal plane and integrates eleven(More)
PURPOSE OF THE STUDY Analysis of the anatomic relations of the humeral head and the glenoid cavity is particularly important for clinical study of shoulder arthroplasty and glenohumeral instability. Analysis of humeral retroversion and glenoid retroversion is quite difficult and data in the literature are scarse. We conducted a computed tomography (CT)(More)
With a cadaveric model, we studied the effects on the superior labrum-biceps tendon complex of a fall on the outstretched hand to assess one of the supposed mechanisms of creation of superior labrum anterior-posterior (SLAP) lesions. Ten shoulders were used to simulate either a forward or a backward fall with a custom shoulder-testing apparatus capable of(More)
The authors present an original fixation technique for olecranon fractures in children, achievable without opening the fracture site. The standard method of Kirschner wire fixation with tension band wiring is replaced by a threaded pin stabilization with adjustable lock effect. An olecranon fracture model was used to compare the mechanical properties of(More)
The purpose of this study is to determine the external forces that are brought to bear on the mandible during 14 masticatory tasks, exerted in three defined mandibular positions. A static two-dimensional mandibular model is presented, taking into account projections in the sagittal plane of the forces exerted by six muscle groups and the joint reaction(More)
PURPOSE OF THE STUDY We have compared three systems for osteosynthesis of proximal humeral fractures on a four-fragment fracture model: Plate with tuberosity screwing (P), Kirschner wires with bone sutures (K) and an original implant, the "bilboquet" (Stryker) (B), composed of a hook for the head supported on a diaphyseal stem.
