A multicenter observational study on the distribution of orthopaedic fracture types across 17 low- and middle-income countries

How does trauma secondary to unexpected extreme weather affect orthopaedic surgery departments? An epidemiological study on the Filomena snowstorm

INTRODUCTION

Trauma secondary to extreme weather events may heavily impact the normal activity of orthopaedic surgery departments, especially in places not prepared to deal with them. The Filomena snowstorm, which happened in January 2021, has been one of the greatest snowstorms ever in Spain. During it, the constant influx of trauma patients made the Orthopaedic Emergencies Department (OED) to collapse. The primary objective of this study was to describe the orthopaedic injuries and changes in fracture's epidemiology observed during this exceptional period. Secondary objectives were to analyse the collected variables in order to minimize the future impact of these unexpected extreme weather events.

MATERIALS AND METHODS

Retrospective cohort study between patients that came to the OED during the snowstorm (Filomena group) and those who came on the same period of the previous year (Control group). The following data were collected: age, sex, injury location, injury mechanism, diagnosis, AO/OTA fracture classification, treatment type (conservative vs surgical) and delay to surgical treatment.

RESULTS

A total of 1237 patients were included in total, 655 patients from the Filomena group and 582 from the Control group. One in two patients in the Filomena group sustained a fracture (50.7% vs 23.2%). The most frequent diagnosis on the Filomena group was distal radius fracture (16.2%), five times more frequent than in the Control group (3.4%). A significant increment was also observed in the incidence of ankle (21.7%) and proximal humerus (33%) fractures. In Filomena, surgically treated fractures increased by 168%, being more severe, as C-type fractures were more prevalent (23% vs 13%). Mean delay to surgery was 6.78 days during the snowstorm.

CONCLUSION

Unexpected snowstorms entail an exponential rise in orthopaedic care demand and OED pressures. A significant increment in orthopaedic trauma surgery, up to 168% more, particularly distal radius, proximal humerus and ankle fractures it is to be expected, which will imply elective surgery cancellation, damaging patients and increasing costs.

Patterns of orthopedic and trauma admissions to a tertiary teaching and referral health facility in Kenya: Chart review

Tertiary hospitals in resource-limited countries should treat referred patients but in reality, are the first level of care for the vast majority of patients. As a result, the tertiary facility effectively functions as a primary health care facility. The urban phenomenon of widespread self-referral is associated with low rates of formal referral from peripheral health facilities. The study objective was to determine the patterns of orthopaedic and trauma admissions to Kenyatta National Hospital. This was descriptive study design. 905 patient charts were reviewed in 2021. The mean age was 33.8 years (SD 16.5) with range of 1-93 years. Majority 66.3% were between 25-64 years with those above 65 years being 40 (4.4%). Children 0-14 years comprised 10.9% of the admissions. Of the 905 admissions, 80.7% were accident and trauma-related admissions while 17.1% were non-trauma related admissions. About 50.1% were facility referrals while 49.9% were walk-ins. Majority of admissions were through Accident and Emergency Department 78.1%, Corporate Outpatient Care 14.9% and orthopedic Clinic 7.0%. About 78.7% were emergency admissions while 20.8% were elective admissions. Approximately 48.5% were due to Road Traffic Accidents and 20.9% due to falls. Close to 44.8% were casual workers and 20.2% unemployed. About 34.0% attained primary education and 35.0% secondary education. About 33.2% of female admissions were due to non-trauma conditions as compared to male admissions (12.8%) (p<0.001). Admissions for those aged 25-64 years were 3.5 more likely to have emergency admission as compared to those aged 0-14 years. Male were 65.1% less likely to have elective admissions compared to female (p<0.001). Whereas lower limb injuries and non-trauma related conditions were the most commonly admitted conditions, Lower limb injury and spine cases were mostly facility referred while non-trauma conditions were walk-in patients. Vast majority (89.2%) of admissions were from Nairobi Metropolitan region.

Screw-only fibular construct for Weber B ankle fractures: A retrospective clinical and cost comparison to assess feasibility for resource-limited settings

INTRODUCTION

Ankle fractures are one of the most common injuries sustained worldwide, with the majority being isolated lateral malleolus fractures. The majority of the world's population live in Low and Middle Income Countries (LMIC), where implant cost may limit surgical treatment of ankle fractures. We investigate if Weber B ankle fractures could be effectively treated with a lower-cost technique using two screws between the fibula and the tibia to neutralize an interfragmentary lag screw.

METHODS

After IRB approval, consecutive patients from January 1, 2020 to December 31, 2020 with Weber-B ankle fractures were treated using AO technique (AOT) with plate osteosynthesis neutralizing an interfragmentary screw. Syndesmotic injuries, as well as injuries to the medial malleolus or foot were treated according to the surgeon's preferences. From January 1, 2021 to December 31, 2021 these injuries were treated with a screw-only technique (SOT) with two fibula pro tibia screws to neutralize an interfragmentary screw. Patient demographics including age, sex, BMI, smoking status, associated rheumatoid arthritis, and associated diabetes mellitus were recorded. The primary outcome variable was a stable radiographic mortise at six weeks post-surgery, secondary outcome variables included clinical union, infection, hardware removal, and implant cost for lateral malleolar fixation charged to the hospital.

RESULTS

Seventeen AOT and 10 SOT constructs were included. Demographic characteristics were similar between groups. All fractures maintained a stable mortise with clinical union at 6 weeks without infection. There was a statistically significant difference in hardware removal (17.6% AOT, 50% SOT, p = 0.012). The average implant cost to the hospital of the lateral malleolar fixation was significantly less in the SOT group ($592 (SD $229)), compared to the AOT group ($1,949.97 (SD $562)), (p < 0.0001).

CONCLUSION

We introduce proof of concept of a novel lower-cost fixation strategy for Weber B ankle fractures that maintained a stable mortise with clinical union at six weeks post-surgery. However, there was a significantly higher rate of hardware removal following fixation with a screw-only construct.

The global burden of fragility fractures - what are the differences, and where are the gaps

The current burden of fragility fractures is enormous, and it is set to increase rapidly in the coming decades as humankind enters a new demographic era. The purpose of this review is to consider, in different settings: • The human and economic toll of fragility fractures. • Risk factors for fragility fractures. • Current acute management of fragility fractures. • Current care gaps in both secondary and primary fracture prevention. A summary of global, regional, and national initiatives to improve the quality of care is provided, in addition to proposals for the research agenda. Systematic approaches to improve the acute care, rehabilitation and prevention of fragility fractures need to be developed and implemented rapidly and at scale in high-, middle- and low-income countries throughout the world. This must be an essential component of our response to the ageing of the global population during the remainder of the current United Nations - World Health Organization "Decade of Healthy Ageing".

Feasibility of delivering foot and ankle surgical courses in a partnership in Eastern, Central and Sothern Africa

BACKGROUND

Foot and ankle pathology if not treated appropriately and in a timely manner can adversely affect both disability and quality adjusted life years. More so in the low- and middle-income countries where ambulation is the predominant means of getting around for the majority of the population in order to earn a livelihood. This has necessitated the equipping of the new generation of orthopaedic surgeons with the expertise and skills set to manage these conditions. To address this need, surgeons from the British Orthopaedic Foot & Ankle Society (BOFAS) and College of Surgeons of Eastern, Central and Southern Africa (COSECSA) transferred the "Principles of Foot and Ankle Surgery" course to an African regional setting. The course was offered to surgical trainees from 14-member countries of the COSECSA region and previously in the UK. The faculty was drawn from practicing surgeons experienced in both surgical education and foot and ankle surgery. The course comprises didactic lectures, case-based discussions in small groups, patient evaluations and guided surgical dissections on human cadavers. It was offered free to all participants. The feasibility of the course was evaluated using the model defined by Bowen considering the eight facets of acceptability, demand, implementation, practicality, adaptation, integration, expansion and limited efficacy. At the end of the course participants were expected to give verbal subjective feedback and objective feedback using a cloud based digital feedback questionnaire. The course content was evaluated by the participants as "Poor", "Below average", "Average", "Good" and "Excellent", which was converted into a value from 1-5 for analysis. The non-parametric categorical data was analysed using the Two-sample Wilcoxon rank-sum (Mann-Whitney) test, and significance was considered to be p < 0.05.

RESULTS

Six courses in total were held between 2018 and 2020. Three in the UK and three in the COSECSA region. There were 78 participants in the three UK courses and 96 in the three courses run in the COSECSA region. Hundred percent of the UK participants and 97% of the COSECSA participants completed the feedback. Male to female ratio was 4:1 for the UK courses and 10:1 for the COSECSA Courses. In both regions all the participants responded that they would recommend the course to their colleagues. Among the COSECSA participants 91% reported that the course was pitched at the right level, which is similar to the 89% of the UK participants (p = 0.28).

CONCLUSION

The BOFAS Principles of Foot and Ankle Surgery course design provides core knowledge, with an emphasis on clinical examination techniques of the foot and ankle, while at the same time, caters for the anticipated difference in the local clinical case mix and resources. This study establishes that by attending the course surgical trainees can achieve their learning goals in foot and ankle surgery with the same high quality qualitative and quantitative feedback in both regions. This would improve their clinical practice and confidence. The multifaceted approach adopted in this course blending didactic teaching, small group discussions, interactive sessions, case-based discussions, cadaveric surgical skills training printed educational materials and feedback helped fulfil these educational objectives. Working in partnership with local expert orthopaedic surgeons from a number of Sub-Saharan countries, was key to adapting the course to local pathology and the COSECSA setting.

Registries: Big data, bigger problems?

Patient registries have grown in size and number along with general computing power and digitization of the healthcare world. In contrast to databases, registries are typically patient data systematically created and collected for the express purpose of answering health-related questions. Registries can be disease-, procedure-, pathology-, or product-based in nature. Registry-based studies typically fit into Level II or III in the hierarchy of evidence-based medicine. However, a recent advent in the use of registry data has been the development and execution of registry-based trials, such as the TASTE trial, which may elevate registry-based studies into the realm of Level I evidence. Some strengths of registries include the sheer volume of data, the inclusion of a diverse set of participants, and their ability to be linked to other registries and databases. Limitations of registries include variable quality of the collected data, and a lack of active follow-up (which may underestimate rates of adverse events). As with any study type, the intended design does not automatically lead to a study of a certain quality. While no specific tool exists for assessing the quality of a registry-based study, some important considerations include ensuring the registry is appropriate for the question being asked, whether the patient population is representative, the presence of an appropriate comparison group, and the validity and generalizability of the registry in question. The future of clinical registries remains to be seen, but the incorporation of big data and machine learning algorithms will certainly play an important role.

Epidemiology of fractures and their treatment in Malawi: Results of a multicentre prospective registry study to guide orthopaedic care planning

IMPORTANCE

Injuries cause 30% more deaths than HIV, TB and malaria combined, and a prospective fracture care registry was established to investigate the fracture burden and treatment in Malawi to inform evidence-based improvements.

OBJECTIVE

To use the analysis of prospectively-collected fracture data to develop evidence-based strategies to improve fracture care in Malawi and other similar settings.

DESIGN

Multicentre prospective registry study.

SETTING

Two large referral centres and two district hospitals in Malawi.

PARTICIPANTS

All patients with a fracture (confirmed by radiographs)-including patients with multiple fractures-were eligible to be included in the registry.

EXPOSURE

All fractures that presented to two urban central and two rural district hospitals in Malawi over a 3.5-year period (September 2016 to March 2020).

MAIN OUTCOME(S) AND MEASURE(S)

Demographics, characteristics of injuries, and treatment outcomes were collected on all eligible participants.

RESULTS

Between September 2016 and March 2020, 23,734 patients were enrolled with a median age of 15 years (interquartile range: 10-35 years); 68.7% were male. The most common injuries were radius/ulna fractures (n = 8,682, 36.8%), tibia/fibula fractures (n = 4,036, 17.0%), humerus fractures (n = 3,527, 14.9%) and femoral fractures (n = 2,355, 9.9%). The majority of fractures (n = 21,729, 91.6%) were treated by orthopaedic clinical officers; 88% (20,885/2,849) of fractures were treated non-operatively, and 62.7% were treated and sent home on the same day. Open fractures (OR:53.19, CI:39.68-72.09), distal femoral fractures (OR:2.59, CI:1.78-3.78), patella (OR:10.31, CI:7.04-15.07), supracondylar humeral fractures (OR:3.10, CI:2.38-4.05), ankle fractures (OR:2.97, CI:2.26-3.92) and tibial plateau fractures (OR:2.08, CI:1.47-2.95) were more likely to be treated operatively compared to distal radius fractures.

CONCLUSIONS AND RELEVANCE

The current model of fracture care in Malawi is such that trained orthopaedic surgeons manage fractures operatively in urban referral centres whereas orthopaedic clinical officers mainly manage fractures non-operatively in both district and referral centres. We recommend that orthopaedic surgeons should supervise orthopaedic clinical officers to manage non operative injuries in central and district hospitals. There is need for further studies to assess the clinical and patient reported outcomes of these fracture cases, managed both operatively and non-operatively.
