doi:10.3415/VCOT-12-12-0154 Our first issue of VCOT for this year contains several papers pertaining to the study of fracture morphology, and the stabilization of fractures with bone plates (1-3). In addition, Herten and colleagues describe the characterization of mesenchymal stem cells isolated from bone marrow by a point-of-care device; these cells had osteogenic potential that could be expec...

The objective of the current study was to compare quantitative data on the biomechanical analysis of different techniques for fixation of intercalary bone defects of the humerus, by means of consistently applied methodology on composite models. A total of 25 humeral specimens of composite models were used. An intercalary defect was created and reconstructed using plates, intramedullary nails, e...

The biomimetic approach mimicking in vivo micro environment is the key for developing functional tissue engineered constructs. In this study, we used a tripolymer combination consisting of a natural polymer, chitosan and two extracellular matrix components; collagen type 1 and hyaluronic acid to coat tissue culture plate to evaluate their effect on osteogenic differentiation of human bone marro...

Cell sheet engineering has emerged as a novel approach to effectively deliver seeding cells for tissue regeneration, and developing human bone marrow mesenchymal stem cell (hBMMSC) sheets with high osteogenic ability is a constant requirement from clinics for faster and higher-quality bone formation. In this work, we fabricated biocompatible and safe chitosan (CS)/hyaluronic acid (HA) nanoparti...

A grossly displaced segmental zygomatic arch fracture with marked ventro-lateral deviation of the left globe was diagnosed in a 3-month-old male German Shepherd dog following a bite injury. The fracture was approached via a modified lateral orbitotomy and a fragment of the lacrimal bone removed. The rostral portion of the fracture was stabilized with a 5-hole 2.0 dynamic compression plate bone ...

The pterygopalatine fossa (PPF) represents a major pathway of spread of malignancy and infection from the head and neck into the skull base. The ability to precisely locate tumor and infection on CT and MR imaging studies is crucial for performing biopsies and planning treatment. Determining the exact margins of the PPF is problematic, because they are not strictly defined even in the anatomic ...

The stability of segments after Le Fort I osteotomy first attracted the researcher's interest when the surgical concept was conceived. Prebent plates are the ultimate modification of plate systems in craniofacial surgery; they have two right angles and are available in different lengths for use in maxillary advancement surgery. For this research, cone-beam computed tomography (CBCT) images of a...

AIM The aim of this retrospective study was to evaluate the outcome of distal femoral fractures type C3 AO, using TARPO technique and plates with angular stability. MATERIAL AND METHODS The study included 17 fractures type C3 AO, with 4 open fractures: 1 type I, 1 type II, and 2 type IIIA with bone loss Gustilo. All patients were operated by TARPO technique using Less Invasive Stabilization S...

OBJECTIVES The aim of the study was to volumetrically assess alterations of the ridge contour after socket preservation and buccal overbuilding. MATERIAL AND METHODS In five beagle dogs, four extraction sites were subjected to one of the following treatments: Tx 1: The socket was filled with BioOss Collagen and covered with a free gingival autograft from the palate (SP). Tx 2: The buccal bone...

Osteoarthritic (OA) changes in knee joints can be assessed by analyzing the structure of trabecular bone (TB) in the tibia. This analysis is performed on TB regions selected manually by a human operator on x-ray images. Manual selection is time-consuming, tedious, and expensive. Even if a radiologist expert or highly trained person is available to select regions, high inter- and intraobserver v...
