[Accident pension after fracture of the pelvic ring and acetabulum : Changes in pension claims and costs following isolated fractures of the pelvic ring and acetabulum in work-related accidents from 2013 to 2019-A DGUV registry analysis].

Background: It is known that fractures of the pelvic ring and acetabulum in work-related accidents are associated with long periods of incapacity to work, a high rate of reduction in earning capacity (MdE) and high costs for pension/severance pay.

Objective: Investigation of changes in pension claims and costs from 2013 to 2019 after isolated fractures of the pelvic ring and acetabulum in work-related accidents in Germany.

Material And Methods: For all patients from the German Social Accident Insurance (DGUV) registry with isolated fractures of the pelvic ring or acetabulum in work-related accidents, linear trend analyses were carried out among others for the proportion of MdE ≥20%, the proportion of cases receiving pension/severance pay and total costs for pension/severance pay from 2013 to 2019.

The infraacetabular screw versus the antegrade posterior column screw in acetabulum fractures with posterior column involvement: a biomechanical comparison.

Introduction: Traditionally, plate osteosynthesis of the anterior column combined with an antegrade posterior column screw is used for fixation of anterior column plus posterior hemitransverse (ACPHT) acetabulum fractures. Replacing the posterior column screw with an infraacetabular screw could improve the straightforwardness of acetabulum surgery, as it can be inserted using less invasive approaches, such as the AIP/Stoppa approach, which is a well-established standard approach. However, the biomechanical stability of a plate osteosynthesis combined with an infraacetabular screw instead of an antegrade posterior column screw is unknown.

Comparison of different intraoperative reduction monitoring methods in a cadaveric intraarticular calcaneal fracture model: 3D scan vs arthroscopy vs nanoscopy.

Aims: Visualization of the subtalar joint surface in surgical management of calcaneal factures remains a big challenge and anatomic reduction of the articular surface is essential for a good clinical outcome. We hypothesize that video-assistance can provide superior fracture reduction compared to fluoroscopy and that nanoscopy (NSC) achieves more extensive visualization compared to fracturoscopy (FSC).

Methods: Ten human cadaveric feet with artificially pre-fractured intraarticular calcaneal fractures with involvement of the posterior facet were treated via a minimal invasive subtalar approach.

Epidemiology and socioeconomic consequences of work-related pelvic and acetabular fractures recorded in the German Social Accident Insurance.

Introduction: Pelvic and acetabular fractures can result from work-related accidents and frequently require lengthy medical treatments. Consequently, high medical costs as well as delayed or absent return to work can be the consequence. Therefore, we aimed to study the socioeconomic consequences of work-related pelvic and acetabular fractures.

Anterolateral versus modified posterolateral approach for tibial plateau fractures with involvement of the posterior column: a cadaveric study.

Introduction: The aim of this study was to compare the reduction quality of the anterolateral (AL) and modified posterolateral approach (PL) in lateral tibial plateau fractures involving the posterior column and central segments.

Methods: Matched pairs of pre-fractured cadaveric tibial plateau fractures were treated by either AL approach (supine position) or PL approach (prone position). Reduction was controlled by fluoroscopy and evaluated as satisfying or unacceptable.

Biomechanical in vitro analysis of a novel flexible implant for pubic symphysis disruption using an ultra-high molecular weight polyethylene fiber cord.

Background: Plate osteosynthesis depicts the gold standard to surgically treat pubic symphysis disruptions. However, high rates of implant failure after plate osteosynthesis are reported, probably because of the iatrogenic arthrodesis of this fibrocartilaginous joint. Therefore, flexible implants for treatment of pubic symphysis disruptions appear to be a sensible solution.

Biomechanical analysis of fixation methods in acetabular fractures: a systematic review of test setups.

Purpose: Optimal anatomical reduction and stable fixation of acetabular fractures are important in avoiding secondary dislocation and osteoarthritis. Biomechanical studies of treatment options of acetabular fractures aim to evaluate the biomechanical properties of different fixation methods. As the setup of the biomechanical test can influence the experimental results, this review aimed to analyze the characteristics, comparability and clinical implications of studies on biomechanical test setups and finite element analyses in the fixation of acetabular fractures.

A Register Analysis after Tibial Plateau Fracture in Statutory Accident Insurance.

Objective: To analyse the results after tibial plateau fractures with a focus on socioeconomic consequences.

Methods: On the basis of the data from the rehabilitation documentation of the German Statutory Accident Insurance (DGUV) on tibial plateau fractures (Code 83), a retrospective anonymised evaluation of the injuries which occurred in 2010 and 2016 was carried out. The registry data allowed subdivision into 3 groups: Medial, lateral and bicondylar tibial plateau fractures.

Stresses and deformations of an osteosynthesis plate in a lateral tibia plateau fracture.

This study has the aim to investigate the strain and stress in an anterolateral locking plate applied for the fixation of a lateral split fracture. To simulate a complex fracture situation, three segments were separated. With a FEM analysis, representative places for strain and stress measurement were determined.

[Pseudarthrosis after bony avulsion fracture of the posterior cruciate ligament].

Background: Tibial bony avulsion fractures of the posterior cruciate ligament (PCL) are rare injuries and in certain cases a delayed healing or non-union can occur under conservative treatment.

Objective: Presentation of the clinical result of patients with pseudarthrosis who were secondarily operated on after bony avulsion of the PCL.

Material And Methods: The study included all patients who were operated on since 2010 for reasons of delayed or non-union PCL avulsion fracture in this clinic.
