Lumbar Interbody Fusion Conducted on a Porcine Model with a Bioresorbable Ceramic/Biopolymer Hybrid Implant Enriched with Hyperstable Fibroblast Growth Factor 2.

Many growth factors have been studied as additives accelerating lumbar fusion rates in different animal models. However, their low hydrolytic and thermal stability both in vitro and in vivo limits their workability and use. In the proposed work, a stabilized vasculogenic and prohealing fibroblast growth factor-2 (FGF2-STAB) exhibiting a functional half-life in vitro at 37 °C more than 20 days was applied for lumbar fusion in combination with a bioresorbable scaffold on porcine models.

Ex-vivo biomechanical testing of pig femur diaphysis B type fracture fixed by novel biodegradable bone glue.

Aims: The aim of this study was to answer the question whether our newly developed injectable biodegradable "self-setting" polymer-composite as a bone adhesive is a good "bone-glue" candidate to efficiently fix comminuted fractures of pig femoral bones used as an ex-vivo experimental model.

Methods: Mechanical properties of adhesive prepared from α-tricalcium phosphate (TCP) powder and thermogelling copolymer were optimized by selecting the appropriate composition with adhesion enhancers based on dopamine and sodium iodinate. Setting time and injectability were controlled by rheology.

[Importance of Skull X-ray in Head Trauma].

PURPOSE OF THE STUDY The aim of our study is to show the pitfalls of performing skull X-rays in patients with head injuries and the lack of accuracy of this examination nowadays, and to clarify the current trend in the MTBI investigation algorithm. MATERIAL AND METHODS A retrospective study of 3,950 patients treated for acute head injury at the Department of Trauma Surgery (University Hospital Brno) in the period from 2015 to 2016. Inclusion criteria were the following: mild brain injury (GCS = 15), primary skull X-ray design in head injury diagnosis.

[Effect of Negative Pressure Wound Therapy on Infectious Complications in Grade III Open Fractures].

Unlabelled: PURPOSE OF THE STUDY Grade III open fractures are associated with infectious complications in 25-66% of injuries. Negative pressure wound therapy (NPWT) applied to an injured soft tissue coverage provides an impermeable barrier between the injured structures and the external environment, in addition to early secretion draining and a positive effect on the site of application. All this also prevents secondary bacterial contamination.
