Hemorrhage in Pelvic Ring Fractures After Low-Energy Trauma: A Systematic Review.

: The aim was to investigate diagnostic, treatment and preventive options to establish an overview of the existing evidence on hemorrhage in pelvic fractures in older adults. : A systematic review was conducted. Due to the rarity of this complication, only case reports and series with individuals older than 55 years with a pelvic ring fracture that is caused by a low-energy trauma or no apparent trauma, along with hemorrhage, were eligible.

Does an instructional video as a stand-alone tool promote the acquisition of practical clinical skills? A randomised simulation research trial of skills acquisition and short-term retention.

Background: The effectiveness of instructional videos as a stand-alone tool for the acquisition of practical skills is yet unknown because instructional videos are usually didactically embedded. Therefore, we evaluated the acquisition of the skill of a humeral intraosseous access via video in comparison to that of a self-study with an additional retention test.

Methods: After ethical approval, we conducted two consecutive studies.

[Surgical Education of Medical Students in Times of COVID-19 - Necessary Adjustments are Chances for the Future].

Background: Education of medical students in surgery not only consists of knowledge about diseases and their treatment but also of practical skills like i.e. suturing.

Pediatric aseptic lower leg fracture nonunion.

Purpose: Lower leg nonunion in pediatric patients is a rarity. Therefore, eight European pediatric trauma units retrospectively analyzed all patients younger than 18 years suffering lower leg fractures resulting in aseptic nonunion.

Methods: Thirteen children and adolescents less than 18 years old (2 girls and 11 boys) diagnosed with aseptic nonunion of the tibia and/or fibula were evaluated.

Results Of The Treatement Of Intracapsular Femoral Neck Fractures With A New Dynamic Locking Plate.

The purpose of this study was to evaluate the outcomes in patients with intracapsular femoral neck fractures treated with the novel Targon FN implant. Sixty two patients (mean age: 57 years) were included. The clinical and radiological results were investigated.

Olecranon tension plating or olecranon tension band wiring? A comparative biomechanical study.

Purpose: The complication rate of a tension band wiring (TBW) used for the internal fixation of olecranon fractures remains high. The aim of this study was to compare the stability of a novel olecranon tension plate (OTP) with TBW in a simulated fracture model.

Methods: We tested 12 fresh frozen-pairs of cadaver proximal ulnae treated with OTP and TBW under cyclic loading.

Clinical pathways for fragility fractures of the pelvic ring: personal experience and review of the literature.

Fragility fractures of the pelvic ring (FFP) are increasing in frequency and require challenging treatment. A new comprehensive classification considers both fracture morphology and degree of instability. The classification system also provides recommendations for type and invasiveness of treatment.

Two-year results of vertebral body stenting for the treatment of traumatic incomplete burst fractures.

Purpose: Vertebral body stenting (VBS) was developed to prevent loss of reduction after balloon deflation during kyphoplasty. The aim of this study is the radiological and clinical mid-term evaluation of traumatic incomplete burst fractures treated by vertebral body stenting.

Material And Methods: This retrospective study included patients with traumatic thoracolumbar incomplete burst fractures treated with VBS between 2009 and 2010.

Long-term outcome after operative treatment of traumatic patellar dislocation in adolescents.

Objectives: Retrospective evaluation of the long-term outcomes after surgical treatment of traumatic patellar dislocations in adolescents and identification of possible predictive factors of poor outcomes.

Design: Retrospective clinical study.

Setting: University Clinic, Level I Trauma Center.

Suture fixation versus cable cerclage of the tuberosities in shoulder arthroplasty-clinical and radiologic results.

Background: The most important individual parameter linked to functional outcome following hemiarthroplasty for fractures of the proximal humerus is anatomical healing of the tuberosities. The aim of our study was to evaluate whether the fixation method influences tuberosity healing and functional outcome.

Methods: Twenty-five consecutive patients with acute 4-part fractures of the proximal humerus were treated with hemiarthroplasty and cable fixation of the tuberosities.

Isolated fractures of the greater tuberosity of the proximal humerus: a long-term retrospective study of 30 patients .

Background And Purpose: The diagnosis and treatment of isolated greater tuberosity fractures of the proximal humerus is not clear-cut. We retrospectively assessed the clinical and radiographic outcome of isolated greater tuberosity fractures.

Patients And Methods: 30 patients (mean age 58 (26-85) years, 19 women) with 30 closed isolated greater tuberosity fractures were reassessed after an average follow-up time of 3 years with DASH score and Constant score.

Retrograde nailing versus locking plate osteosynthesis of proximal humeral fractures: a biomechanical study.

Background: In locking plate osteosynthesis of proximal humeral fractures, secondary varus malalignment is a specific complication. Retron nails (Tantum AG, Neumunster, Germany), among others, have been designed to improve medial support of the calcar humeri. The aim of our biomechanical study was to examine whether Retron nails provide increased stiffness for axial loads and adequate stiffness for torsional loads when compared with Philos plates (Synthes AG, Umkirch, Germany).

Development of a multisegmental test body to calibrate and validate studies with spinal testing devices with follower load.

Introduction: Spinal testing devices need a tool for calibration and comparison of accomplished studies. The objective of this study was the development of a polysegmental test body, which simulates several functional spinal motion units and provides a standard calibration.

Materials And Methods: The test body consists of aluminum moldings simulating the vertebral bodies, rubber discs simulating the intervertebral discs and cylindrical guide elements with ball joints simulating the vertebral joints.

Biomechanical effect of different interspinous devices on lumbar spinal range of motion under preload conditions.

Introduction: Interspinous devices are used as an alternative to the current gold standard treatment, decompressive surgery with or without fusion, for lumbar spinal stenosis. They are supposed to limit extension and expand the spinal canal and foramen at the symptomatic level, but still allow lateral bending and axial rotation in the motion segment. The aim of the present study is the biomechanical evaluation of the change in the range of motion of the affected and adjacent segments following implantation of different interspinous devices under load in all directions of motion.

Non-traumatic shoulder instability in an athletic patient with a periglenoidal cyst and a glenoid labral tear.

A 34-year-old patient presented to our outpatient clinic with the chief complaint of shoulder instability, without any history of trauma. Physical examination revealed a painful apprehension test at 60 degrees, 90 degrees and 120 degrees but no objective sign of shoulder instability or hyperlaxity. MRI-scan showed a cyst over the anterior inferior glenoid rim.
