The success rate of orthopaedic implants is strongly dependent on the initial fixation, but the objective intra-operative assessment of primary stability of cementless implants is still a challenge and, moreover, excessive press-fitting of the implant can cause intraoperative fractures. In a series of in vitro and in vivo experiments the change in the frequency response function (FRF) of the hi...
Multimodality imaging has emerged as a common technological approach used in both preclinical and clinical research. Advanced techniques that combine in vivo optical and μCT imaging allow the visualization of biological phenomena in an anatomical context. These imaging modalities may be especially useful to study conditions that impact bone. In particular, orthopaedic implant infections are an ...
In the last decade, Calcium Titanate has been introduced as a bioceramic with acceptable mechanical and biological properties for orthopaedic implant applications. In this study, CaTiO3 nano-structure coating was produced by sol-gel dip-coating route for biomedical applications. Calcium nitrate and titanium isopropoxide were used as a precursor. After coating process, the specimen was subject...
BACKGROUND Surgical site infections can follow clean orthopaedic operations and can cause serious morbidity, mortality and increased resource utilization. Despite this, there are few studies on risk factors for surgical site infections in the Nigerian orthopaedic literature. We conducted a prospective study to determine the host and environmental risk factors for surgical site infections follow...
PURPOSE. To investigate consultant surgeons' knowledge about the costs of implants for various joint surgeries. METHODS. Questionnaires were distributed to consultant orthopaedic surgeons at 2 hospitals. Respondents were asked to estimate the implant costs of any brand for low-demand and high-demand total hip replacement (THR), total knee replacement (TKR), uni-compartmental knee replacement, a...
BACKGROUND Recent advances in non-invasive optical, radiographic and μCT imaging provide an opportunity to monitor biological processes longitudinally in an anatomical context. One particularly relevant application for combining these modalities is to study orthopaedic implant infections. These infections are characterized by the formation of persistent bacterial biofilms on the implanted mater...
INTRODUCTION: Osseointegration is crucial for early fixation as well as long-term success of orthopaedic implants. Contaminants, such as bacterial debris and manufacturing residues, can remain on an implant surface after sterilization procedures and inhibit osseointegration [1]. Bacterial debris contains pathogen associated molecular patterns (PAMPs), which are molecular motifs that activate th...
