Finite element (FE) methods are widely used in electrical impedance tomography (EIT) to enable rapid image reconstruction of different tissues based on their electrical conductivity. For EIT of brain function, anatomically-accurate (head-shaped) FE meshes have been shown to improve the quality of the reconstructed images. Unfortunately, given the lack of a… (More)
Lateral unicompartment knee replacements are performed infrequently in the United Kingdom. This study evaluates the experience of two knee surgeons in a District General Hospital for all lateral unicompartmental arthroplasties performed between October 2007 and August 2011. Two different implants were used in this time period, the Oxford domed and the… (More)
Total hip and knee replacements (THR and TKR) are a common procedure. Transfusion rates have fallen in the literature over the past decade, and this study aimed to quantify the transfusion rates and identify the clinical transfusion threshold in our centre, which uses a multimodal enhanced recovery after surgery (ERAS) programme. A retrospective review of… (More)
Reconstruction of images in Electrical Impedance Tomography (EIT) of brain function in the adult head benefits from the use of accurate numerical models, which may utilize meshes created by the Finite Element Method (FEM). Previously, these have been produced by manual segmentation and parametric representation of surfaces which were later meshed, but this… (More)
OBJECTIVE This study was undertaken to evaluate the use of digital tomosynthesis (tomogram) for diagnosis of suspected fracture neck of femur (NOF). We hypothesised that the use of cross-sectional imaging (MRI/CT) could be reduced by using tomogram to separate the patients with suspected NOF fractures that require MRI/CT scan from those who do not. … (More)
Unstable 4 part pertrochanteric fractures without lateral cortical support presents considerable technical problem in treatment with high risk of failure with any implant. Anatomical or slight valgus reduction and subchondral central position of the lag screw (TAD <25 mm) reduces the chance of screw cut out and other complications.
To improve SHO confidence in corneal foreign body removal, a novel training phantom is proposed. This phantom is a polyvinyl and gelatine-based model, easily fabricated in the emergency department (ED). Use of the phantom results in a significant improvement in SHO confidence, and therefore, makes a useful, cost-effective adjunct for ED training.
Sciatic nerve palsy has been well documented and reported, following primary and revision hip replacement. It can also occur following dislocation of hip replacement. The incidence of sciatic nerve palsy in dislocated hip replacement is <0.1%. However, new onset sciatic nerve palsy following a closed reduction of dislocated hip replacement is even rarer. We… (More)
Primary repair of pectoralis major tendon with bony tunnels and anchor sutures in the proximal humerus creates a potential weakness and stress riser leading to increased risk of periprosthetic fracture and nerve damage at the site of weakness with subsequent injury, if not allowed to heal satisfactorily with adequate period of rest.
The patient had a total knee replacement for arthritis secondary to Stills disease performed 35 years earlier, with 20 years of good function followed by 15 years of progressively worsening knee pain. A revision was completed, which improved the patient's quality of life and objective knee scores, with an increase in Oxford Knee Score from 22 to 42 and… (More)
