The effect of the design of the orthosis on the axial load transmission of two flexion abduction orthoses used in treating congenital hip dysplasia.

Background: With an incidence of 2-4% in all newborns, developmental dysplasia of the hip, DDH, represents the most frequent congenital disorder of the skeletal system in Germany. The therapy options are deduced with the help of a sonography. The conservative therapy approach includes the application of flexion abduction orthoses, which lead to a development of the child's hip through abduction and flexion angle.

Association of Lumbar MRI Findings with Current and Future Back Pain in a Population-based Cohort Study.

Study Design: Population-based cohort study.

Objective: We examined associations between common lumbar degenerative changes observed on magnetic resonance imaging (MRI) and present or future low back pain (LBP).

Summary Of Background Data: The association between lumbar MRI degenerative findings and LBP is unclear.

Internship Experience in Orthopaedics and Traumatology and its Impact on Becoming a Specialist.

Introduction: The German practical year is the last clinical placement period during Medical School. However, it remains unclear how medical students evaluate the practical year in orthopaedics and traumatology (Orthopädie und Unfallchirurgie; O & U) and whether it has an impact on becoming an O & U specialist.

Method: We analysed data of 146 medical students (46,7% female) who completed the placement in O & U.

[Frequencies of musculoskeletal symptoms and disorders in the population-based German National Cohort (GNC)].

Background: Musculoskeletal diseases and symptoms are very common in the general population. They lead to high healthcare costs and pose a significant burden to the national economy.

Objectives: Based on data from the population-based German National Cohort (GNC), frequencies of musculoskeletal symptoms and diseases are reported, including back pain, osteoporosis, osteoarthritis, and arthritis.

The neck-shaft angle: an update on reference values and associated factors.

Background and purpose - The neck-shaft angle (NSA) is valuable for diagnostics and therapy of the hip, but current reference values derive mostly from studies on anatomic specimens, small cohorts, or are hospital-based. Moreover, associated factors such as age, sex, or anthropometric data have rarely been considered. Therefore, we determined associated factors for NSA and reassessed the historical reference values in a general adult population.

Prevalence of benign osseous lesions of the spine and association with spinal pain in the general population in whole body MRI.

Background: Benign osseous lesions of the spine are common but precise population prevalence estimates are lacking. Our study aimed to provide the first population-based prevalence estimates and examine association with back and neck pain.

Materials And Methods: We used data from the population-based Study of Health in Pomerania (SHIP).

[Mandatory Surgical Subinternship in the Final Year of Medical School - a Stepping Stone to Becoming a Surgeon?].

Background: The final year is an important time for a medical student as this is when medical knowledge is transformed into medical responsibilities. The field of surgery is firmly anchored in the educational structure as it is mandatory during the practical year of a medical student. The purpose of this paper is to identify factors that influence medical students to choose surgery after the final year of medical school.

Combination Drug Therapy for the Management of Low Back Pain and Sciatica: Systematic Review and Meta-Analysis.

Combining medicines may give greater pain relief and/or improved tolerability. We conducted a systematic review to investigate the effects of combination drug therapy in patients with low back pain and/or sciatica on pain, disability, and adverse events. Databases and trial registers were searched from inception to July 27, 2017, for randomized trials of (sub)acute or chronic back pain or sciatica participants that were administered combination drug therapy compared with monotherapy or placebo.

What Are the Reference Values and Associated Factors for Center-edge Angle and Alpha Angle? A Population-based Study.

Background: The available evidence regarding normal ranges for the center-edge angle and the alpha angle derives from a few small studies, and associated factors such as sex and anthropometric factors have not been well evaluated. Knowing more about normal values for these parameters is critical, because this can inform decisions about when to perform elective hip preservation surgery. Population-level studies would provide considerable clarity on these issues, but to our knowledge, no such studies are available.

[Quality and Satisfaction with the Surgical Medical Clerkship from a Student Perspective].

Preface: The surgical medical clerkship is of special importance, as the student is given the opportunity to get in touch with medical colleagues and patients for the first time, and the interest in a certain field of specialisation can be consolidated. The present study will clarify how students perceived their medical clerkship in the field of surgery.

Methods: A nationwide online survey carried out in 2012 was able to recruit 9079 participants, and contained questions about the completed curricular internships.

[Young Academics in Neuropsychological Disciplines: Factors Affecting Career Aspiration in Psychiatry, Neurology and Psychosomatic Medicine].

Objective: Students with specialization preferences in psychiatry, neurology, or psychosomatic medicine were retrospectively compared with regard to aspects of motivation to choose medicine as their field of study.

Methods: To identify early predictors of specialization preferences, a nationwide online survey was conducted with 9079 medical students. The statements of those with a preference for neurology, psychiatry, or psychosomatic medicine were evaluated using analysis of variance (ANOVA).

[Nursing Internship Internal Medicine: Evaluation and Influences on the Attitude towards the Specialization].

 German medical students have to perform a nursery internship of three month duration. While this internship is widely discussed, there is a lack of student evaluation data.  Here, for the first time, student evaluation of a nursery internship in internal medicine (IM) is investigated.

Comparative Analysis of Direct Hospital Care Costs between Aseptic and Two-Stage Septic Knee Revision.

Background: The most common intermediate and long-term complications of total knee arthroplasty (TKA) include aseptic and septic failure of prosthetic joints. These complications cause suffering, and their management is expensive. In the future the number of revision TKA will increase, which involves a greater financial burden.

Does antibiotic resistance impair plasma susceptibility of multi-drug resistant clinical isolates of enterococci in vitro?

Background: Cold atmospheric plasma could constitute an alternative against multi-drug resistant pathogens. Susceptibility of enterococci to cold atmospheric plasma was investigated in vitro.

Methods: 39 clinical isolates of enterococci were grouped dependent on the most important resistance patterns and treated on agar using dielectric barrier discharge plasma.

In vitro susceptibility of methicillin-resistant and methicillin-susceptible strains of Staphylococcus aureus to two different cold atmospheric plasma sources.

Background: Staphylococcus aureus may be the most important wound pathogen and causative for most of surgical site infections. As many anti-staphylococcal drugs are useless because of resistance, novel antimicrobial strategies are strongly needed and may be provided by cold atmospheric plasma (CP), which is being currently investigated for antiseptic efficacy.

Methods: To test the antimicrobial properties of CP against Staphylococcus aureus, 168 methicillin-susceptible isolates (MSSA) and 50 methicillin-resistant isolates (MRSA) were treated with two technically different plasma sources [an atmospheric pressure plasma jet (APPJ) and a dielectric barrier discharge plasma (DBD)] in vitro.

Plasma disc decompression compared to physiotherapy for symptomatic contained lumbar disc herniation: A prospective randomized controlled trial.

Introduction: To evaluate clinical outcomes with PDD as compared with patients who underwent to standard physiotherapy intervention.

Material And Methods: One-hundred-seventy-seven randomly assigned patients with primarily radicular pain associated with a single-level lumbar contained disc herniation were enrolled. Participants received either PDD (89 patients) or conservative physiotherapy care (88 patients).

A New Electromagnetic Navigation System for Pedicle Screws Placement: A Human Cadaver Study at the Lumbar Spine.

Introduction: Technical developments for improving the safety and accuracy of pedicle screw placement play an increasingly important role in spine surgery. In addition to the standard techniques of free-hand placement and fluoroscopic navigation, the rate of complications is reduced by 3D fluoroscopy, cone-beam CT, intraoperative CT/MRI, and various other navigation techniques. Another important aspect that should be emphasized is the reduction of intraoperative radiation exposure for personnel and patient.
