The study deals with the determination of mechanical properties, namely resistance to bending forces, of flexible buttress osteosynthesis using two different bone-implant constructs stabilizing experimental segmental femoral bone defects (segmental ostectomy) in a miniature pig ex vivo model using 4.5 mm titanium LCP and a 3 mm intramedullary pin (“plate and rod” construct) (PR-LCP), versus the...

early osteointegration. On-growth of bone to porous coated prostheses is influenced by many factors such as the composition and topography of the surface, as well as the local biological and mechanical environment in the immediately adjacent bone. Given that the short stem femoral implant is orientated in a more oblique to transverse trajectory, it might be subjected to greater bending moments ...

BACKGROUND The current method of treatment for persistent internal rotation due to the medial rotation contracture in patients with obstetric brachial plexus injury is humeral derotational osteotomy. While this procedure places the arm in a more functional position, it does not attend to the abnormal glenohumeral joint. Poor positioning of the humeral head secondary to elevation and rotation of...

Bone marrow derived mesenchymal stem cells (BMSC) represent an attractive cell population for tissue engineering purpose. The objective of this study was to determine whether the addition of recombinant human bone morphogenetic protein (rhBMP-2) and insulin-like growth factor (IGF-1) to a silica-coated calcium hydroxyapatite (HASi) - rabbit bone marrow derived mesenchymal stem cell (rBMSC) cons...

BACKGROUND The most common sequelae after surgical removal of mandibular third molar are pain, trismus, swelling, and dysphagia. However, these symptoms can also signal the onset of surgical site infection and alveoli osteitis. The aim of this study was to evaluate the efficacy of prophylactic amoxicillin/clavulanic acid and levofloxacin and preemptive therapy of amoxicillin/clavulanic acid in ...

IMPORTANCE Pediatric jaw cysts represent a rarely symptomatic clinical entity and are not well addressed in the otolaryngology literature. It is important that otolaryngologists should be familiar with these lesions, which can manifest as jaw swelling or as paranasal sinus abnormalities. OBJECTIVE To review the clinical presentation, radiologic features, management, and outcomes of jaw cysts ...

Grayton, J. 40 CASE REPORT A 27 month-old, castrated, male domestic short hair cat was presented with acute onset of non-weight-bearing right pelvic limb lameness of four hours duration. The cat was kept indoors and had no history of trauma. Pain was elicited on manipulation of the right pelvic limb. At first the lameness appeared to be centered at the tarsus; radiographs of the right tarsus we...

BACKGROUND Though used for over a century, structural bone allografts suffer from a high rate of mechanical failure due to limited graft revitalization even after extended periods in vivo. Novel strategies that aim to improve graft incorporation are lacking but necessary to improve the long-term clinical outcome of patients receiving bone allografts. The current study evaluated the effect of lo...
