PURPOSE To evaluate the fixation strength at the interface between the Kerboull-type plate and bone cement in 6 experimental conditions. METHODS Experimental materials comprised a simulated acetabular block, a simulated Kerboulltype plate, a pressuriser cover, a pressuriser arm, and bone cement. The simulated Kerboull-type plate was placed on the simulated acetabular block, with the pressuris...

The fundamental problem in osteoporotic fracture treatment is significant decrease in bone mass and bone tissue density resulting in decreased firmness and elasticity of osteoporotic bone. Application of standard implants and standard surgical techniques in osteoporotic bone fracture treatment makes it almost impossible to achieve stable osteosynthesis sufficient for early mobility, verticaliza...

Distal fibula fractures are the most common injury of weight bearing bones. Several studies have shown the benefit of locking plates especially in osteoporotic bone. The aim of this biomechanical study was to test the anatomically shaped VariAx Distal Lateral Fibula Plate in comparison to a commonly used 1/3 Tubular Plate. The implants were assembled to bone surrogates simulating a comminuted f...

Abstract Introduction: Fractures in osteoporotic bones present a surgical challenge for fixation and are often associated with significant morbidity. Case presentation: We case of failed internal fracture femoral shaft 74-year-old patient osteoporosis. Fracture was undertaken using an extra medullary locking plate intramedullary cortical strut graft, hybrid technique, Locking Plate Allograft Co...

Despite increasing evidence that subchondral bone contributes to osteoarthritis (OA) pathogenesis, little is known about local changes in bone structure compared to cartilage degeneration. This study linked structural adaptation of subchondral bone with histological OA grade. Twenty-five osteochondral samples of macroscopically different degeneration were prepared from tibiae of 14 patients. Sa...

The loss of the buccal alveolar plate following tooth extraction in the maxillary anterior region is an especially challenging condition for the clinician. Immediate implant placement with a flapless approach has been suggested in order to reduce postextraction bone loss. In the presence of a significant vertical gap in the buccal plate after tooth extraction, most authors still recommend a bon...

BACKGROUND To assess the clinical feasibility of lingual bone guttering technique for surgical extraction of mandibular third molars. MATERIALS AND METHODS 20 patients with thick lingual cortical plate were included in the study. Surgical extraction of mandibular third molars by lingual bone guttering technique was performed in all the subjects. These subjects were evaluated for integrity of ...

The clinical case of figure 1 through figure 11 shows a series of impressive failures of plate fixation. The plates were repeatedly applied bridging a comminuted bone segment in a heavy patient. The biomechanical analysis elaborates why this happened and proposes an unconventional procedure to prevent this failure with a minimally invasive procedure. A plate bridging an open gap or a defect in ...
