Absorbable plates are used widely for fixation of facial bone fractures. Compared to conventional titanium plating systems, absorbable plates have many favorable traits. They are not palpable after plate absorption, which obviates the need for plate removal. Absorbable plate-related infections are relatively uncommon at less than 5% of patients undergoing fixation of facial bone fractures. The ...

The attachment of an implant material to bone relates to surface roughness and surface chemistry. There is a relatively low chemical bonding strength of so-called bioactive surfaces. Hydroxyapatite interfaces typically have an interfacial tensile strength of 0.15-1.5 MPa. An attachment force similar to that of bioactive surfaces might also be reached through mechanical interlock with ordinary b...

Osseous defects of the jaws following trauma, cysts, infection or congenital deformity may show poor osteogenesis and the affected area may never be completely filled with bone. It is widely accepted in guided tissue regeneration that physically halting soft connective tissue proliferation into bone allows bone regeneration. This concept is called the "osteopromotion principle." The purpose of ...

Abstract: The aim of the present study was to evaluate histologically vertical bone regeneration outcomes after using bovine bone graft material in block and granular forms. The buccal bony plates of the outer mandibles of ten New Zealand rabbits received BioOss® blocks that were immobilized using orthopedic mini-plates and other ten received granular forms that was gently packed and stabilized...

P. K. Saha, F. W. Wehrli University of Pennsylvania, Philadelphia, PA 19104, United States SYNOPSIS: Trabecular bone (TB) is a network of interconnected struts and plates. During remodeling the bone responds to the forces to which it is subjected and the trabeculae thus follow major stress lines (Wolff’s law). Trabecular anisotropy can be expressed in terms of the fabric tensor. Next to volume ...

The purpose of the present study was to compare the results and plate fit of periprosthetic and non-periprosthetic distal femur fractures fixed with locking plates. Twenty-one periprosthetic fractures above a TKA and 27 non-periprosthetic fractures were retrospectively reviewed. The primary healing rate, bone union time, clinical and radiographic results, complications, and additional surgeries...

Complex periarticular fractures of the long bones are difficult to treat. Classic intramedullary osteosynthesis do not provide a stable fixation (Wiss et al., 1986), while open reduction and rigid fixation by classic plates (recommended in the 60s-70s) is requiring large incisions with important deperiostation. Potential complications as infections, consolidation delays and construct damage due...

The mechanical stimuli resulting from weight loading play an important role in mature bone remodeling. However, the effect of weight loading on the developmental process in young bones is less well understood. In this work, chicks were loaded with bags weighing 10% of their body weight during their rapid growth phase. The increased load reduced the length and diameter of the long bones. The ave...

Microscopy imaging of mouse growth plates is extensively used in biology to understand the effect of specific molecules on various stages of normal bone development and on bone disease. Until now, such image analysis has been conducted by manual detection. In fact, when existing automated detection techniques were applied, morphological variations across the growth plate and heterogeneity of im...
