Our aim was to investigate whether nitric oxide synthase (NOS) isoforms, responsible for the generation of NO, are expressed during the healing of fractures. To localise the sites of expression compared with those in normal bone we made standardised, stabilised, unilateral tibial fractures in male Wistar rats. Immunostaining was used to determine the(More)
BACKGROUND Clavicle fractures account for around 4% of all fractures and up to 44% of fractures of the shoulder girdle. Fractures of the middle third (or mid-shaft) account for approximately 80% of all clavicle fractures. Management of this group of fractures is often challenging and the outcome can be unsatisfactory. In particular it is not clear whether(More)
Aseptic loosening is a major cause of failure of total hip arthroplasty. The adverse tissue response to prosthetic wear particles, with activation of cytokine and prostanoid production, contributes to bone loss around the implants. We have investigated the possibility that inducible nitric oxide synthase (iNOS) and cyclo-oxygenase-2 (COX-2) are expressed in(More)
BACKGROUND Reviewing litigation brought against health institutions is a clinical governance issue and can help to prevent further cases. While large-scale databases are rare, the British National Health Service Litigation Authority deals with claims brought against all public health trusts in England. METHODS We reviewed all 2312 successful cases(More)
Nitric oxide is emerging as one of the most studied molecules in many aspects of human physiology and pathophysiology. Because of the inflammatory nature of aseptic loosening of total hip replacement, it is likely that nitric oxide plays a major role in this condition as well. Nitric oxide is known to interact with cyclooxygenase enzymes that produce(More)
Age-related changes in the expression of the growth associated protein GAP-43/B-50, and the neuropeptides substance P and calcitonin gene-related peptide (CGRP) were investigated in the sensory neurones of rat dorsal root ganglia, dorsal horns of the spinal cord and subintimal knee synovium. The two time-points studied were 2 months (young adults) and(More)
An experimental model of fracture healing has been used to investigate whether nitric oxide mediated vascular reactivity, determined using laser Doppler flowmetry, is present in bone after a fracture. Times corresponding to Days 0, 1, 3, 7, 14, and 28 after fracture were used to study the injured and contralateral limbs in response to bolus intravenous(More)
There is an inability to properly record and archive findings of arthroscopic procedures. We have developed an interactive, free Web-based operative note template that allows the surgeon to draw findings on diagrams of the joints commonly undergoing arthroscopy, type the findings, and then print as many copies as required. The use of the forms has allowed(More)
The treatment of distal humeral periprosthetic fractures is not widely described in the literature. We present a difficult clinical scenario of a 72-year-old man who sustained a displaced distal humeral periprosthetic fracture about a Polarus Plus intramedullary nail. In this case, stable fixation was achieved using bicondylar Acumed Mayo congruent Plates(More)
Good short term results have led to increased use of synthetic ligaments for acute and chronic acromioclavicular joint (ACJ) disruption. They have proved quite safe in the short term but we present two cases of osteolysis following ACJ reconstruction using a synthetic ligament, reminding surgeons of potential complications with artificial ligaments. A high(More)
