Retrospective Analysis of Nosocomial SARS-CoV-2 Infections in Orthopedic and Traumatological Inpatients.

SARS-CoV-2 has had a measurable impact on the field of orthopedic and traumatological surgery. To date, scarce data on intramural SARS-CoV-2 infections in orthopedic and traumatological patients have been reported. Therefore, the aim of our study was to investigate the effect of nosocomial SARS-CoV-2 infections in orthopedic and traumatological inpatients regarding symptoms of infection, mortality, duration of hospitalization, and other relevant patient-dependent factors.

Bone tunnel placement influences shear stresses at the coracoid process after coracoclavicular ligament reconstruction: a finite element study and radiological analysis.

Introduction: Coracoid fractures after arthroscopic treatment of acromioclavicular (AC) joint separations lead to poor clinical outcomes. In this study, different configurations of bone tunnels in the lateral clavicle and coracoid were examined concerning the amount of stress induced in the coracoid.

Methods: An authentic 3D finite element model of an ac joint was established.

A biomechanical comparison of steel screws versus PLLA and magnesium screws for the Latarjet procedure.

Introduction: The fixation of the coracoid process onto the glenoid is an important step of the Latarjet procedure, and implant-associated complications are a relevant and severe problem. This study compares the fixation strength and failure mode of two biodegradable materials with stainless-steel screws.

Methods: 24 Fresh-frozen cadaveric scapulae were divided into three groups of equal size and received a coracoid transfer.

Evaluation of mushroom-shaped allograft for unstable proximal humerus fractures.

Introduction: Proximal humerus fractures are common injuries of the elderly. Different treatment options, depending on fracture complexity and stability, have been recommended in the literature. Particularly for varus displaced fractures with a lack of medial support, and patients suffering from osteoporosis, structural allografts can be used to enhance the stability of the construct.

Measuring bone defects for acetabular revision surgery for choosing an appropriate reconstruction strategy: A concept study on plastic models.

Background: Bone defects can be filled with autografts, allografts and artificial bone-materials. The aim of this study was to evaluate whether the digitization of known defect models with a navigation system is a reliable measurement method for estimating the size of a bone defect.

Methods: Six preformed, cylindrical and cone-shaped defects on an artificial hip-bone were digitalized by six different observers.
