We report a 30-year-old patient who was involved in a high-velocity road traffic accident and developed a left-sided hemiparesis, which was noted in the post-operative period following bilateral femoral intramedullary nailing. CT scanning of the brain revealed infarcts in the right frontal and parietal lobes in the distribution of the right middle cerebral artery. CT angiography showed occlusion of the right internal carotid artery consistent with internal carotid artery dissection. He was anticoagulated and nine months later was able to walk independently. An awareness of this injury is needed to diagnose blunt trauma to the internal carotid artery. Even in the absence of obvious neck trauma, carotid artery dissection should be suspected in patients with a neurological deficit in the peri-operative period

Introduction

Virtual fracture clinics (VFCs) are being increasingly used to offer safe and efficient orthopaedic review without the requirement for face-to-face contact. With the onset of the COVID-19 pandemic, we sought to develop an online referral pathway that would allow us to provide definitive orthopaedic management plans and reduce face-to-face contact at the fracture clinics.

Surgeons are at risk from both hepatitis B and human immunodeficiency viruses. While vaccines have been developed against the former, barrier methods remain the mainstay of protection. Puncture wounds of the hand are a potential source of contamination; the protection afforded by surgical gloves has been investigated. Gloves from 280 orthopaedic operations for trauma were tested for perforations; one or more was found after 30% of the operations in gloves worn by the surgeon or scrub nurse. About 60% of the perforations were noticed at the time of penetration and most affected the dominant thumb and index finger. Puncture was more common during operations lasting more than one hour. The incidence of perforation was 19% for the outer of double gloves, 14% for a single glove and 6% for the inner of double gloves. These results indicate that surgical gloves function poorly as a protective barrier, especially in difficult, lengthy, fracture surgery. The practice of double-gloving confers increased but not absolute protection

The surgical correction of scoliosis in adolescents involves considerable trauma to bone and muscle which, together with hypotensive anaesthesia, might be expected to compromise renal function. Our recent observation of acute renal failure in two such patients prompted a prospective study of renal function following 52 operations in 43 patients. Despite hypotension, blood loss, muscle damage and evidence of fat embolism, renal function was unaltered in all patients, and there was no impairment of spinal cord function. Careful attention was paid to the maintenance of circulating volume which is essential to protect renal perfusion

The use of robots in orthopaedic surgery is an emerging field that is gaining momentum. It has the potential for significant improvements in surgical planning, accuracy of component implantation and patient safety. Advocates of robot-assisted systems describe better patient outcomes through improved pre-operative planning and enhanced execution of surgery. However, costs, limited availability, a lack of evidence regarding the efficiency and safety of such systems and an absence of long-term high-impact studies have restricted the widespread implementation of these systems. We have reviewed the literature on the efficacy, safety and current understanding of the use of robotics in orthopaedics.

Aims

The aim of this study was to inform a definitive trial which could determine the clinical effectiveness of the X-Bolt Dynamic Hip Plating System compared with the sliding hip screw for patients with complex pertrochanteric fragility fractures of the femur.

Aims

The aim of this study was to assess the current evidence relating to the benefits of virtual reality (VR) simulation in orthopaedic surgical training, and to identify areas of future research.

A major pathway of closed soft-tissue injury is failure of microvascular perfusion combined with a persistently enhanced inflammatory response. We therefore tested the hypothesis that hypertonic hydroxyethyl starch (HS/HES) effectively restores microcirculation and reduces leukocyte adherence after closed soft-tissue injury. We induced closed soft-tissue injury in the hindlimbs of 14 male isoflurane-anaesthetised rats. Seven traumatised animals received 7.5% sodium chloride-6% HS/HES and seven isovolaemic 0.9% saline (NS). Six non-injured animals did not receive any additional fluid and acted as a control group. The microcirculation of the extensor digitorum longus muscle (EDL) was quantitatively analysed two hours after trauma using intravital microscopy and laser Doppler flowmetry, i.e. erythrocyte flux. Oedema was assessed by the wet-to-dry-weight ratio of the EDL. In NS-treated animals closed soft-tissue injury resulted in massive reduction of functional capillary density (FCD) and a marked increase in microvascular permeability and leukocyte-endothelial cell interaction as compared with the control group. By contrast, HS/HES was effective in restoring the FCD to 94% of values found in the control group. In addition, leukocyte rolling decreased almost to control levels and leukocyte adherence was found to be reduced by ~50%. Erythrocyte flux in NS-treated animals decreased to 90 ± 8% (mean . sem. ), whereas values in the HS/HES group significantly increased to 137 ± 3% compared with the baseline flux. Oedema in the HS/HES group (1.06 ± 0.02) was significantly decreased compared with the NS-group (1.12 ± 0.01). HS/HES effectively restores nutritive perfusion, decreases leukocyte adherence, improves endothelial integrity and attenuates oedema, thereby restricting tissue damage evolving secondary to closed soft-tissue injury. It appears to be an effective intervention, supporting nutritional blood flow by reducing trauma-induced microvascular dysfunction
