PURPOSE OF REVIEW: To describe the practice of and recent developments in the osteo-odonto-keratoprosthesis. RECENT FINDINGS: Formal psychological assessment and support have been described. A sub-aqua system for fashioning the osteo-odonto-keratoprosthesis lamina; adoption of thicker laminae; use of bisphosphonate drugs; advances in laminar imaging; and use of bone augmentation and bone morphogenetic protein have been described for prevention, detection, and management of laminar resorption...

Functional outcomes and complications in otosclerosis surgery are governed by the surgeon's experience. Thus, teaching the procedure to residents to guide them through the learning process as quickly as possible is challenging. Artificial 3D-printed temporal bones are replacing cadaver specimens in many institutions to learn mastoidectomy, but these are not suitable for middle ear surgery training. The goal of this work was to adapt such an artificial temporal bone to aid the teaching of otosclerosis surgery and to evaluate this tool...

Autologous bone grafting is an established method to overcome bone deficiencies in primary total knee arthroplasty (TKA). However, recently, metal augments have been used by many surgeons. Although autologous bone grafting is a common technique, few large studies have described its success in achieving bone union in primary TKA. The goal of this study was to evaluate primary TKA with autologous bone grafting for tibial defects. A total of 68 knees that had undergone arthroplasty with autologous bone grafting with more than 1 year of follow-up were evaluated...

Complex glenoid deformities present the most difficult challenges in shoulder arthroplasty. These deformities may be caused by severe degenerative or congenital deformity, posttraumatic anatomy, tumor, or, in most cases, bone loss after glenoid failure in anatomical total shoulder arthroplasty. Methods of treating severe bone loss have included inlay and onlay bone-graft options with augmented fixation and, in severe cases, salvage hemiarthroplasty with limited goal expectations. Unfortunately, none of these methods has provided consistently satisfactory reproducible results...

The relationship between marrow adipose tissue (MAT) and bone health is poorly understood. We used running exercise to ask whether obesity-associated-MAT can be attenuated via exercise and whether this correlates with gains in bone quantity and quality. C57BL/6 mice were divided into diet-induced obesity (DIO n = 14) vs. low-fat diet (LFD n = 14). After 3 months, 16-week-old mice were allocated to an exercise intervention (LFD-E, DIO-E) or a control group (LFD, DIO) for 6 week (4 groups, n = 7/group)...

INTRODUCTION: The role of surgery in skeletal metastasis is to reduce morbidity and improve the quality of life in terminally ill patients. We report our experience with patients who underwent skeletal reconstructive surgery for metastatic bone tumour of the femur. MATERIALS AND METHODS: Twenty nine operations for skeletal metastasis of the femur performed in our centre between 2009 and 2015 were included in this study. We evaluated the choice of implant, complications, survival rate and functional outcome...

Chronic Myeloid Leukemia (CML) is characterized by translocations between chromosomes 9 and 22, resulting in expression of Bcr-abl oncogenes. Although the clinical course of CML was revolutionized by development of Bcr-abl-directed tyrosine kinase inhibitors (TKIs), CML is not cured by these agents. Specifically, the majority of subjects relapsed in clinical trials attempting TKI discontinuation, suggesting persistence of leukemia stem cells (LSCs) even in molecular remission. Identifying mechanisms of CML-LSC persistence may suggest rationale therapeutic targets to augment TKI efficacy and lead to cure...

BACKGROUND AND OBJECTIVE: 5-Fluorouracil (5-FU) is a first-line chemotherapeutic drug in colorectal cancer. However, intravenous administration of 5-FU at the dose of 7-12mg/kg exhibits curbs like short half-life (20min) and toxic side-effects on bone marrow cells. Therefore, in present investigation, 5-FU was conjugated to poly (ethylene glycol) anchored recombinant human serum albumin nanoparticles (5-FU-rHSA-PEG-NPs) to improve the pharmacokinetic and therapeutic profiles. METHODS AND RESULTS: The mean particle size of 5-FU-rHSA-NPs was measured to be 44...

BACKGROUND: Immediate implant placement followed by an immediate restoration has proven to be a viable technique in the anterior maxillary region. PURPOSE: This prospective study evaluated the mid-long term (2-5 years) tissue changes around immediately placed and restored implants in the anterior maxilla using flapless surgery and simultaneous hard tissue augmentation.

OBJECTIVE: This research attempts to identify the part the hippocampus plays in accelerated fracture-healing after traumatic brain injury as well as to test functions of calcitonin gene-related peptide (CGRP) during this process. MATERIALS AND METHODS: Experiments were carried out on Male Sprague-Dawley rats that were split into four groups at random: TBI-fracture group, fracture-only group, TBI-only group, and control group. In the first week, blood specimen would be drawn from rats among the groups except those of the control group at three-time points (24, 72 and 168 hours) post-damage...

Background Iliac crest bone graft harvesting is routinely performed for upper extremity orthopedic procedures despite high complication rates associated with sensory nerve injury, hematoma, chronic pain, and fracture. Description of Technique Cancellous bone graft is harvested from the proximal tibia using a medial approach, minimizing donor site morbidity. Patients and Methods A retrospective review was undertaken of 14 patients who underwent cancellous proximal tibia bone graft harvesting to augment healing of wrist reconstruction, with 2 months minimum follow-up...

Socket preservation maintains bone volume post-extraction in anticipation of an implant placement or fixed partial denture pontic site. This procedure helps compensate for the resorption of the facial bone wall. Socket preservation should be considered when implant placement needs to be delayed for patient or site-related reasons. The ideal healing time before implant placement is six months. Socket preservation can reduce the need for later bone augmentation. By reducing bone resorption and accelerating bone formation it increases implant success and survival...

Cement augmentation in vertebrae (vertebroplasty) is usually used to restore mechanical strength after spinal fracture but could also be used as a prophylactic treatment. So far, the mechanical competence has been determined immediately post-treatment, without considering long-term effects of bone adaptation. In this work, we investigated such long-term effects of vertebroplasty on the stiffness of the augmented bone by means of computational simulation of bone adaptation. Using micro-finite element analysis, we determined sites of increased mechanical stress (stress raisers) and stress shielding and, based on the simulations, regions with increased or decreased bone loss due to augmentation...

PURPOSE: Structure-property relations, which relate the shape of the microstructure to physical properties such as transport or mechanical properties, need sensitive measures of structure. What are suitable fabric tensors to quantify the shape of anisotropic heterogeneous materials? The mean intercept length is among the most commonly used characteristics of anisotropy in porous media, e. g., of trabecular bone in medical physics. Yet, in this series of two papers we demonstrate that it has conceptual shortcomings that limit the validity of its results...

Bone marrow-derived mesenchymal stem cells (BM-MSCs) contribute to myocardial repair after myocardial infarction (MI) by secreting a panel of growth factors and cytokines. This study was to investigate the potential mechanisms of the nuclear casein kinase and cyclin-dependent kinase substrate 1 (NUCKS) in regulation of the profiles of BM-MSCs secretion and compare the therapeutic efficacy of NUCKS(-/-)- and wide type-BM-MSCs (WT-BM-MSCs) on MI. The secretion profiles between NUCKS(-/-)- and WT-BM-MSCs under hypoxia (1%O2) were analyzed...

REVIEW
J Breeze, M S Dover, R W Williams
Hypodontia is the term most commonly applied to the condition in which teeth congenitally fail to develop. Such cases differ from teeth that have been lost early or that have failed to erupt, although their initial presentation may be similar and therefore not recognised. The range of missing teeth and their physical and psychological results is large, and the difference in complexity in the management of a patient with isolated hypodontia compared with one with oligodontia or anodontia together with skeletal and orthognathic discrepancies should not be underestimated...
