The management of injury to the distal tibiofibular syndesmosis remains controversial in the treatment of ankle fractures. Operative fixation usually involves the insertion of a metallic diastasis screw. There are a variety of options for the position and characterisation of the screw, the type of cortical fixation, and whether the screw should be removed prior to weight-bearing. This paper reviews the relevant anatomy, the clinical and radiological diagnosis and the mechanism of trauma and alternative methods of treatment for injuries to the syndesmosis.

Metastatic spinal cord compression is compression of the spinal cord or cauda equina as a result of metastatic deposits in the spinal column. It affects approximately 4000 cases per year in England and Wales. Prompt identification and treatment of metastatic spinal cord compression is necessary to prevent irreversible neurological injury, treat pain and maintain patients' mobility, function and independence. Survival of patients with common malignancies has improved significantly with the ongoing development of radiotherapy and chemotherapy, as well as improved surgical treatment of resectable primary tumours. This article outlines the clinical approach to presentation, pathophysiology, diagnosis and management.

Total knee replacement (TKR) achieves an immediate and exceptional restoration in the quality of life that is comparable only to a few other procedures. It has been suggested that the most common cause of revision TKR is error in surgical technique, from malpositioning of the components which results in a poorer post-operative outcome. Based on the theoretical assumption that the use of computer-assisted systems (CAS) in TKRs may improve implant alignment and thus implant longevity, the use of this technology is becoming increasingly popular. This article (a) reviews whether computer-assisted TKR (CASTKR) results in improved prosthesis alignment compared with the conventional technique, (b) assesses the functional and clinical outcomes of CASTKR and (c) evaluates the cost-effectiveness of using this technology.Résumé La prothèse totale du genou (TKR) permet de restaurer une qualité de vie comparable à peu d'autres techniques. Il est courant de penser que la cause la plus habituelle de reprise des prothèses du genou est secondaire à une erreur technique du fait d'un mauvais positionnement des composants. Sur le plan théorique, l'utilisation de la navigation (CAS) permet d'améliorer l'alignement des implants et donc la longévité de la prothèse. Cette technique devenant de plus en plus populaire. Cet article permet d'analyser les résultats en fonction de l'utilisation de la navigation comparée à une technique conventionnelle, avec évaluation clinique, fonctionnelle (CATKR) ainsi que le rapport coût/utilité de cette technique.

Aims In the UK, deaths associated with COVID-19 have occurred in two waves. Evidence has shown an increase in 30-day mortality for hip fracture patients co-infected with COVID-19. However, there are no studies analysing mortality trends between the first two waves of the UK pandemic. Additionally, hospital versus community acquired COVID-19 infection between the two waves has not been analysed. Furthermore, predictive factors of 30-day mortality have not been fully evaluated. Methods Data from two audits conducted by the CHIP collaborative group were used: a published regional audit in England of nine hospitals providing the COVID-19 negative cases and an unpublished UK national audit of 43 hospitals, which provided the COVID-19 positive cases. Data collection for the COVID-19 positive cases was from 23 March to 31 December 2020. September 1, 2020 was used to define the transition between the two waves. Results There were 517 COVID-19 positive hip fracture patients and 1445 COVID-19 negative hip fracture patients. Overall, 30-day mortality rates were 5.7% in the COVID-19 negative group and 22.4% in the COVID-19 positive patients ( p < 0.001). A difference in survival function between the first and second waves was found ( p = 0.038). To allow for significant demographic differences, a matched analysis of 185 patients found a 26.5% 30-day mortality in the first wave compared to 21.1% in the second wave ( p = 0.222). Within the COVID-19 positive groups, the virus was hospital acquired in 66.7% of cases in the first wave and 72.8% of cases in the second wave ( p = 0.130). Independent predictors of mortality were found to include COVID-19 positive status, AMTS ≤ 6, male gender and age. Conclusion There was a reduction in 30-day mortality for hip fracture patients co-infected with COVID-19 between the two UK pandemic waves but this was not statistically significant. There was no reduction in hospital acquired COVID-19 infection between the two waves.
