Do age, gender, and region affect tibial slope? A multi-center study.

INTRODUCTION: Tibial slope is a parameter that is important to recognize in knee kinematics and knee surgery. A very wide range of values governing posterior tibial slope exist in the literature. This study is based on the hypothesis that age, gender and region may have an effect on the tibial slope. MATERIALS AND METHODS: A total of 1800 lateral knee radiographies from five different countries [Turkey, Germany, Italy, Spain, and the United Kingdom (UK)] were utilized to measure the native posterior tibial slope. Participants were categorized in deciles with each decade of age after 40 years determined as a separate age group. Accordingly, four different age categories were formed in total, namely, the 40- to 49-, 50- to 59-, 60-69, and 70- to 79-year-old groups. Patients with severe knee osteoarthritis, those with a history of arthroscopic and open surgery around the knee, and those with severe morbid obesity and those outside the specified age group were excluded from the study. The angle between the line tangential to the medial tibial plateau and the proximal anatomical axis of the tibia was measured. RESULTS: The tibial slope values of both males and females in the Turkish population were found to be higher than those in other populations. It was observed that tibial slope values increased with age in females in all populations, except for those in the Spanish and UK populations. In the male population, it was found that tibial slope values increased with age in all populations except in the Spanish population. CONCLUSIONS: Region, age, and gender affect tibial slope in different populations in various ways. Our study shows that the region an individual lives in and living conditions affect the tibial slope.

The anatomical shape of the proximal femur correlates with the distal femur anatomy.

PURPOSE: In the case of stemmed implants for lower limb joint arthroplasty procedures, implant stability and survivorship generally rely on the strength of fixation in the medullary canal regardless of whether the procedure is primary or revision surgery. This study aimed to investigate the relationship between the proximal (Dorr classification) and distal (Citak classification) femoral canal geometry classification systems. METHODS: A total of 200 patients who received standing long leg radiographs (hip to ankle) at our institution were identified using our institutional electronic radiology database. Patients were recruited into 4 groups. There were 100 male and 100 female patients with each of those being split into 50 right-sided and 50 left-sided long-leg standing anteroposterior (AP) radiographs. Two independent, blinded observers reviewed each radiograph on two separate occasions, with a minimum of a one-week interval between sittings to review each respective radiograph. RESULTS: No statistically significant correlation was found between demographic data and clinical measurements. A statistically significant correlation was found between the patient's age and BMI results and Citak and Dorr measurements. There was excellent inter-observer and intra-observer agreement for the Citak and Dorr Classifications. The mean Cronbach's α coefficient was 0.96 (range 0.93-0.98) for the Citak Classification and 0.95 (range 0.83-0.97) for the Dorr Classification. There was also an excellent intra-observer agreement with 95% average pairwise per cent agreement for the Citak Classification and 95% average pairwise per cent agreement for the Dorr classification. A statistically significant positive correlation was found between Dorr Calcar Isthmus and Citak Ratio (p < 0.05). CONCLUSION: In this study, the Dorr and Citak classifications are put into relation to each other for the first time. The morphology of the femur was investigated in its entirety and it was shown that there was a positive correlation between the anatomical shape of the proximal and distal medullary canals.

Total fibula dislocation: A rare variant of a Bosworth fracture-dislocation injury.

To our knowledge and from our review of the literature, this is a previously unreported variant of a Bosworth fracture - total fibula dislocation. A 45 year old male presented after a high energy external rotation injury to his lower leg and was diagnosed with a total fibula dislocation with the distal fibula dislocated and incarcerated posteriorly to the tibia. Definitive management was operative with fixation of the proximal tibiofibular joint and repair of the posterolateral corner structures as well as fixation distally of the syndesmosis injury. A graded rehabilitation programme was followed and 6 months postoperatively the patient was hill walking and jogging. Bosworth fracture-dislocations are rare injuries that can often be missed during the initial presentation, especially when there is no fracture associated with a dislocation. An underappreciation for the severity of this injury can have major sequelae and the clinician should have a high index of suspicion when diagnosing this injury. An appreciation for Bosworth fracture dislocations and their variations are important for the trauma surgeon.

Acute Fracture Neck of Femur Among Inpatients: Severe Injuries Which Need to be Taken Seriously.

OBJECTIVES: This study assesses fall prevention measures and subsequent incident reporting of falls resulting in an "inpatient fracture neck of femur (FNOF)" within a single NHS Trust, with the aim of identifying potential areas of improvement and changing practice within a Trust. METHODS: Forty patients (mean age, 82.6 years) sustained an injury while being treated in hospital for an unrelated cause between January 2012 and June 2013. Case notes and incident reports were analyzed retrospectively. RESULTS: Thirty-three (82.5%) of 40 patients had at least 1 fall screen on admission, with 27 patients (81.8%) identified as a fall risk. Fifteen patients (37.5%) had at least one fall before sustaining a FNOF. Fifteen falls occurred between midnight-0500 hours and only 4 falls were witnessed. Thirty-nine of 40 falls were reported, but none were rated as "severe" injuries. Twenty-eight (71.8%) of 39 patients had a root cause analysis performed for the injury, but only 10 root cause analyses (25.6%) produced an action plan. Fifty percent of patients died within 1 year of injury. CONCLUSION: Accurate fall risk assessments and adequate patient supervision are essential to minimize risks of falls, as the inpatient FNOF is linked to a higher mortality rate than patients injured in the community. A standardized method of analyzing such incidents and dissemination of the results of investigation are also required to reduce the risk of similar incidents from occurring within the hospital environment.

Global cancer surgery: delivering safe, affordable, and timely cancer surgery.

Surgery is essential for global cancer care in all resource settings. Of the 15.2 million new cases of cancer in 2015, over 80% of cases will need surgery, some several times. By 2030, we estimate that annually 45 million surgical procedures will be needed worldwide. Yet, less than 25% of patients with cancer worldwide actually get safe, affordable, or timely surgery. This Commission on global cancer surgery, building on Global Surgery 2030, has examined the state of global cancer surgery through an analysis of the burden of surgical disease and breadth of cancer surgery, economics and financing, factors for strengthening surgical systems for cancer with multiple-country studies, the research agenda, and the political factors that frame policy making in this area. We found wide equity and economic gaps in global cancer surgery. Many patients throughout the world do not have access to cancer surgery, and the failure to train more cancer surgeons and strengthen systems could result in as much as US $6.2 trillion in lost cumulative gross domestic product by 2030. Many of the key adjunct treatment modalities for cancer surgery--e.g., pathology and imaging--are also inadequate. Our analysis identified substantial issues, but also highlights solutions and innovations. Issues of access, a paucity of investment in public surgical systems, low investment in research, and training and education gaps are remarkably widespread. Solutions include better regulated public systems, international partnerships, super-centralisation of surgical services, novel surgical clinical trials, and new approaches to improve quality and scale up cancer surgical systems through education and training. Our key messages are directed at many global stakeholders, but the central message is that to deliver safe, affordable, and timely cancer surgery to all, surgery must be at the heart of global and national cancer control planning.

The inpatient fracture neck of femur: an important subgroup of patients.

Fractured neck of femur (FNOF) is an increasing problem for the National Health Service (NHS) with 61,508 recorded on the National Hip Fracture Database (NHFD) in 2012­2013 and treatment of such patients is estimated to cost the NHS £1.5 billion per year. Inpatients falling in hospital and sustain a FNOF have rarely been studied as a separate group of patients to assess standards of patient care, time to operative management, and patient mortality. Of 694 patients sustaining an acute FNOF at a single trust between January 2012 and June 2013, 40 patients (5.8%) sustained an inpatient FNOF. 19 patients (47.5%) were male and 15 patients (37.5%) had an ASA grade of 4 or 5, compared to 153 patients (23.4%) and 127 patients (19.4%) respectively of "community" FNOF. 39 of 40 patients received operative management. Patients with an "inpatient" FNOF were less likely to be admitted to an orthopaedic ward within 4 h (30%) and receive operative management within 48 h (65%) according to "Blue Book" standards. Results according to best practice tariff (BPT) were also significantly reduced for the "inpatient" FNOF group, with 23 patients (57.5%) receiving operative management within 36 h and only 19 patients (47.5%) achieving BPT compared to 76.5% and 72.5% respectively for "community" FNOF patients. Mortality among inpatients reached 40% at 120 days and 50% at 1 year, significantly higher than community FNOF patients after multivariate analysis. Patients sustaining an "inpatient" FNOF are more likely to have significant medical co-morbidity and require aggressive medical and surgical management, especially due to their increased risk of mortality post-operatively. Such injuries have direct and indirect financial implications to a health care trust, which can be minimised by prompt management of these patients. This study highlights the need for a standardised protocol of management of this important subgroup of patients and for further work on falls prevention strategies within the National Health Service.

The path towards universal health coverage in the Arab uprising countries Tunisia, Egypt, Libya, and Yemen.

The constitutions of many countries in the Arab world clearly highlight the role of governments in guaranteeing provision of health care as a right for all citizens. However, citizens still have inequitable health-care systems. One component of such inequity relates to restricted financial access to health-care services. The recent uprisings in the Arab world, commonly referred to as the Arab spring, created a sociopolitical momentum that should be used to achieve universal health coverage (UHC). At present, many countries of the Arab spring are considering health coverage as a priority in dialogues for new constitutions and national policy agendas. UHC is also the focus of advocacy campaigns of a number of non-governmental organisations and media outlets. As part of the health in the Arab world Series in The Lancet, this report has three overarching objectives. First, we present selected experiences of other countries that had similar social and political changes, and how these events affected their path towards UHC. Second, we present a brief overview of the development of health-care systems in the Arab world with regard to health-care coverage and financing, with a focus on Egypt, Libya, Tunisia, and Yemen. Third, we aim to integrate historical lessons with present contexts in a roadmap for action that addresses the challenges and opportunities for progression towards UHC.
