Biomechanical Variability and Usability of a Novel Customizable Fracture Fixation Technique

A novel in situ customizable osteosynthesis technique, Bonevolent™ AdhFix, demonstrates promising biomechanical properties under the expertise of a single trained operator. This study assesses inter- and intra-surgeon biomechanical variability and usability of the AdhFix osteosynthesis platform. Six surgeons conducted ten osteosyntheses on a synthetic bone fracture model after reviewing an instruction manual and completing one supervised osteosynthesis. Samples underwent 4-point bending tests at a quasi-static loading rate, and the maximum bending moment (BM), bending stiffness (BS), and AdhFix cross-sectional area (CSA: mm²) were evaluated. All constructs exhibited a consistent appearance and were suitable for biomechanical testing. The mean BM was 2.64 ± 0.57 Nm, and the mean BS was 4.35 ± 0.44 Nm/mm. Statistically significant differences were observed among the six surgeons in BM (p < 0.001) and BS (p = 0.004). Throughout ten trials, only one surgeon demonstrated a significant improvement in BM (p < 0.025), and another showed a significant improvement in BS (p < 0.01). A larger CSA corresponded to a statistically significantly higher value for BM (p < 0.001) but not for BS (p = 0.594). In conclusion, this study found consistent biomechanical stability both across and within the surgeons included, suggesting that the AdhFix osteosynthesis platform can be learned and applied with minimal training and, therefore, might be a clinically viable fracture fixation technique. The variability in BM and BS observed is not expected to have a clinical impact, but future clinical studies are warranted.

[Simulations in continuing education for more patient safety : Do simulation and skills training influence patient safety in Germany?]

The secure mastering of manual skills and their regular training lead to a reduction of errors and to an improvement of patient safety. Due to increasing economic pressure and bureaucratization, there is less exposure and insufficient time in the clinical routine to communicate all the contents of continuing education. This is why surgical simulation has become increasingly relevant to improve surgical performance in residents. Nowadays, many forms of simulation training are offered in Germany; however, such training on a model is costly and personnel-intensive. In order to justify the effort, objective measurements are becoming more important to qualify the effectiveness of simulation-based training in Germany.

Orthopaedic Trauma Surgeons' Financial Relationships With Industry: An Analysis of the Sunshine Act Reporting of Physician Open Payments From 2014 to 2019

INTRODUCTION

Orthopaedic trauma surgeons have an intricate relationship with the medical device industry. In the past decade, legislation has created transparency of monetary exchanges between physicians and industry. In 2013, the Physician Payments Sunshine Act was passed and ultimately led to the creation of the Open Payments Database. The purpose of this study was to evaluate trends in industry payments to orthopaedic trauma surgeons.

METHODS

A retrospective review of the Centers for Medicare & Medicaid Services' Open Payments Database was conducted for general industry payments to orthopaedic trauma surgeons from 2014 to 2019. Total payments and subtype payments were analyzed for yearly trends. All payments were converted to 2019 US dollars to adjust for inflation. Descriptive statistics included analysis of payments, number of surgeons, types of payments, top contributing companies, and regional comparisons. Trends were assessed through the Jonckheere-Terpstra test. Statistical significance was defined at P < 0.05.

RESULTS

From 2014 to 2019, 45,312 individual payments were given to orthopaedic trauma surgeons (N = 3208) accounting for a total of $41,376,397.85 (USD), with a mean of $919.54 per payment. Increased trends were noted for median annual payments, number of payments, and number of surgeons receiving payments. Compared with 2014 ($460.91), median payments were increased by 90.9% in 2016 ($879.85), 102.6% in 2018 ($933.81), and 178.6% in 2019 ($1284.06). Payment subtypes that demonstrated increasing median payments included consulting fees (P = 0.028); education (P < 0.001); entertainment, food, and beverage (P < 0.001); and travel (P = 0.019). Decreases in median payments were seen in royalties (P = 0.044) and grant funding (P < 0.001). Regional comparisons demonstrated increasing trends in median payments in the midwest (P = 0.011), south (P < 0.001), and west (P = 0.003), but not in the northeast (P = 0.081).

DISCUSSION

In our study, we found that industry payments to orthopaedic trauma surgeons were increasing markedly between 2014 and 2019, particularly among consulting fees, education, entertainment, food and beverage, and travel.

From creative thinking to scientific principles in clinical practice

Stephan Perren's contributions to the understanding and application of the principles of bone pathobiology, healing, and fracture fixation to clinical care remain as a lasting legacy of a great creative mind. Less well appreciated perhaps were his important contributions to the dissemination and practical application of those principles through the use of technology as applied to the learning environment. This paper describes and pays tribute to a series of initiatives in which Perren was a leading mentor and collaborator in the development of methods and instruments through which the principles of bone mechano-pathobiology could be translated through active learning environments into the practical world of clinical musculoskeletal traumatology.

Impact of osteosynthesis in fracture care: a cost comparison study

Aim: To estimate the health economic impact of osteosynthesis (OS) in fracture care over six decades in 17 high-income countries. Patients & methods: Applying a decision tree model, we assumed a hypothetical absence of OS and compared OS (intervention) with conservative treatment (CONS; comparator). We included patients with femur, tibia and radius fractures (age <65 years) and for proximal femur fractures also elderly patients (≥70 years). Results: We estimated savings in direct and indirect costs of 855 billion Swiss francs in the working age population in addition to 4.6 million years of life gained. In the elderly population, 69 billion Swiss francs were saved in direct costs of proximal femur fractures in addition to 73 million years of life gained. Conclusion: OS contributed to maximize health gains of society.
