Dead-space management, following dead bone resection, is an important element of successful chronic osteomyelitis treatment. This study compared two different biodegradable antibiotic carriers used for dead-space management, and reviewed clinical and radiological outcomes. All cases underwent single-stage surgery and had a minimum one-year follow-up. A total of 179 patients received preformed calcium sulphate pellets containing 4% tobramycin (Group OT), and 180 patients had an injectable calcium sulphate/nanocrystalline hydroxyapatite ceramic containing gentamicin (Group CG). Outcome measures were infection recurrence, wound leakage, and subsequent fracture involving the treated segment. Bone-void filling was assessed radiologically at a minimum of six months post-surgery.Aims
Methods
Mesenchymal stromal/stem cells (MSCs) are increasingly recognized as regulators of immune cells during disease or tissue repair. During these situations, the extracellular matrix (ECM) is very dynamic and therefore, our studies aim to understand how ECM influences the activity of MSCs. Human MSCs cultured on tissue culture plastic (TCP) and encapsulated within collagen type I, fibrin, or mixed Collagen-Fibrin were exposed to low dose TNFα and IFNɣ. Transcription profiles were examined using bulk RNA sequencing (RNAseq) after 24h of treatment. ELISA, Western blot, qPCR and immunofluorescence were employed to validate RNAseq results and to investigate the significance of transcriptional changes. Flow cytometry evaluated monocyte/macrophage phenotype.Abstract
Objectives
Methods
To investigate factors that contribute to patient decisions regarding attendance for arthroplasty during the COVID-19 pandemic. A postal questionnaire was distributed to patients on the waiting list for hip or knee arthroplasty in a single tertiary centre within the UK. Patient factors that may have influenced the decision to attend for arthroplasty, global quality of life (QoL) (EuroQol five-dimension three-level (EQ-5D-3L)), and joint-specific QoL (Oxford Hip or Knee Score) were assessed. Patients were asked at which ‘COVID-alert’ level they would be willing to attend an NHS and a “COVID-light” hospital for arthroplasty. Independent predictors were assessed using multivariate logistic regression.Aims
Methods
The aim of this study was to assess the clinical application of, and optimize the variables used in, the BACH classification of long-bone osteomyelitis. A total of 30 clinicians from a variety of specialities classified 20 anonymized cases of long-bone osteomyelitis using BACH. Cases were derived from patients who presented to specialist centres in the United Kingdom between October 2016 and April 2017. Accuracy and Fleiss’ kappa (Fκ) were calculated for each variable. Bone involvement (B-variable) was assessed further by nine clinicians who classified ten additional cases of long bone osteomyelitis using a 3D clinical imaging package. Thresholds for defining multidrug-resistant (MDR) isolates were optimized using results from a further analysis of 253 long bone osteomyelitis cases.Objectives
Methods
This case series aims to describe the clinical consequences of juxta-physeal sub-acute osteomyelitis in children, specifically growth and limb deformity. All children diagnosed with osteomyelitis between 2014 and 2016 at a single University Teaching Hospital in the UK were included. Juxta-physeal sub-acute osteomyelitis was identified using magnetic resonance imaging obtained within 48-hours of presentation. These cases were followed up prospectively on a regular basis in the outpatient clinic. Any clinical evidence of limb or growth deformity was evaluated using long-leg standing radiographs.Aims
