Category: Bunion; Other Introduction/Purpose: Minimally invasive surgery for hallux valgus deformity is gaining popularity over the traditional Open scarf osteotomy. Emerging evidences are showing similar clinical outcomes but further studies are needed to ascertain this. The aim of this study was to assess the feasibility of conducting a randomised controlled trial to compare the patient recorded and clinical outcomes for the surgical management of Hallux Valgus between open scarf osteotomy (OS) and minimally invasive chevron osteotomy (MICA). Methods: Patients suitable for surgical correction were invited to participate. Post op rehabilitation was standardised for both groups. Patients completed a validated questionnaire (Manchester Oxford Foot questionnaire and EQ-5D) preoperatively and post operatively at 6 months and 1 year. Radiological parameters and range of motion were measure pre and post operatively. A total of 41 patients were eligible for the study, 31 were successfully recruited and operated between Dec 2017 and June 2022. Results: 17 patients were randomised to MIS (15 female, mean age 51 years) and 14 to OS (13 female, mean age 51 years). Both groups have a significant improvement in the MOXFQ parameters (walking, pain and social) at 6m and 12m, as well as radiological parameters. VAS improved for OS at 6m (p=0.048) and 12m (p=0.025) but only improvement at 6m was seen for MICA (p=0.059 and p=0.054 at 12m). There was no improvement in EQ-5D in either group at 12 months and no difference in surgical time (p=0.53).There was a higher number of complication in the MICA group with 5 removal of metalwork (29.4%) and 2 superficial infections (11.8%) vs none in the OS group. Conclusion: Both surgical options show similar clinical results but higher complication rate was seen with MICA. A larger study is needed to evaluate further.

Background The principles of global surgery should be taught as a part of the core curriculum in medical schools. The need for medical students to be familiar with the topic is increasing in acceptance. There is, however, a paucity of data on how medical students are exposed to global surgery. This study aims to evaluate exposure of medical students to global surgery, awareness of the key messages of the Lancet Commission on Global Surgery, global surgery career aspirations and barriers to said aspirations. Methods ISOMERS was a multi-centre, online, cross-sectional survey of final year medical students globally. The questionnaire utilised a combination of Likert-scale, multiple-choice, and free text questions. Results In this study, 1593 final year medical students from 144 medical schools in 20 countries participated. The majority ( n  = 869/1496, 58.1%) believed global surgery to be relevant, despite 17.7% ( n  = 271/1535) having any exposure to global surgery. Most participants ( n  = 1187/1476, 80.4%) wanted additional resources on global surgery. Difficulty in providing appropriate care for patients living abroad ( n  = 854/1242, 68.8%) was the most common perceived barrier to a career in global surgery. Conclusions Participants believed global surgery was a relevant topic for medical students and wanted additional resources that they could access on global surgery. It is critical for medical students to become aware that global surgery is a field that aims to address inequity in surgical care not just internationally, but nationally and locally as well.

BackgroundHyponatraemia often occurs after subarachnoid haemorrhage (SAH). However, its clinical significance and optimal management are uncertain. We audited the screening, investigation and management of hyponatraemia after SAH.MethodsWe prospectively identified consecutive patients with spontaneous SAH admitted to neurosurgical units in the United Kingdom or Ireland. We reviewed medical records daily from admission to discharge, 21 days or death and extracted all measurements of serum sodium to identify hyponatraemia (<135 mmol/L). Main outcomes were death/dependency at discharge or 21 days and admission duration >10 days. Associations of hyponatraemia with outcome were assessed using logistic regression with adjustment for predictors of outcome after SAH and admission duration. We assessed hyponatraemia-free survival using multivariable Cox regression.Results175/407 (43%) patients admitted to 24 neurosurgical units developed hyponatraemia. 5976 serum sodium measurements were made. Serum osmolality, urine osmolality and urine sodium were measured in 30/166 (18%) hyponatraemic patients with complete data. The most frequently target daily fluid intake was >3 L and this did not differ during hyponatraemic or non-hyponatraemic episodes. 26% (n/N=42/164) patients with hyponatraemia received sodium supplementation. 133 (35%) patients were dead or dependent within the study period and 240 (68%) patients had hospital admission for over 10 days. In the multivariable analyses, hyponatraemia was associated with less dependency (adjusted OR (aOR)=0.35 (95% CI 0.17 to 0.69)) but longer admissions (aOR=3.2 (1.8 to 5.7)). World Federation of Neurosurgical Societies grade I–III, modified Fisher 2–4 and posterior circulation aneurysms were associated with greater hazards of hyponatraemia.ConclusionsIn this comprehensive multicentre prospective-adjusted analysis of patients with SAH, hyponatraemia was investigated inconsistently and, for most patients, was not associated with changes in management or clinical outcome. This work establishes a basis for the development of evidence-based SAH-specific guidance for targeted screening, investigation and management of high-risk patients to minimise the impact of hyponatraemia on admission duration and to improve consistency of patient care.
