Artificial intelligence in traumatology.

Aims: The aim of this study was to create artificial intelligence (AI) software with the purpose of providing a second opinion to physicians to support distal radius fracture (DRF) detection, and to compare the accuracy of fracture detection of physicians with and without software support.

Methods: The dataset consisted of 26,121 anonymized anterior-posterior (AP) and lateral standard view radiographs of the wrist, with and without DRF. The convolutional neural network (CNN) model was trained to detect the presence of a DRF by comparing the radiographs containing a fracture to the inconspicuous ones.

Free functional gracilis transfer for reconstruction of isolated anterior deltoid atrophy following surgical proximal humerus fixation.

Background: Palsy of the clavicular head of the deltoid is a complication after surgical fixation of proximal humerus fractures. Flexion of the shoulder joint may be impaired as a result. Additionally, patients may complain of joint instability, visible atrophy, and pain.

Orthogeriatric co-management in pelvic and acetabular fractures.

Background: Osteoporosis, age and frailty significantly impacts outcomes in fragility fractures of the pelvis, increasing morbidity and mortality. Identifying frailty aids in risk stratification and personalized care plans, enhancing recovery and reducing complications in older adults. Orthogeriatric co-management, an interdisciplinary approach combining orthopedics and geriatrics, optimizes care for older adults with fragility fractures.

A survey and analysis of peri-operative quality indicators promoted by National Societies of Anaesthesiologists in Europe: The EQUIP project.

Nail fixation of unstable trochanteric fractures with or without cement augmentation: A cost-utility analysis in the United States: Cost-utility of cement augmentation.

Objectives: Recent clinical studies have shown favorable outcomes for cement augmentation for fixation of trochanteric fracture. We assessed the cost-utility of cement augmentation for fixation of closed unstable trochanteric fractures from the US payer's perspective.

Methods: The cost-utility model comprised a decision tree to simulate clinical events over 1 year after the index fixation surgery, and a Markov model to extrapolate clinical events over patients' lifetime, using a cohort of 1,000 patients with demographic and clinical characteristics similar to that of a published randomized controlled trial (age ≥75 years, 83 % female).

Gender-specific distribution of knee morphology according to CPAK and functional phenotype classification: analysis of 8739 osteoarthritic knees prior to total knee arthroplasty using artificial intelligence.

Purpose: Osteoarthritis of the knee is commonly associated with malalignment of the lower limb. Recent classifications, as the Coronal Plane Alignment of the Knee (CPAK) and Functional Phenotype classification, describe the bony knee morphology in addition to the overall limb alignment. Data on distribution of these classifications is not sufficient in large populations.

Significant differences in functional outcome between upper and lower limbs after vascular trauma of the extremities.

Background: This study aimed to compare the functional results between upper (UE) and lower extremity (LE) following arterial reconstruction due to vascular trauma.

Methods: Patients treated for arterial injuries with vascular reconstruction at two centres between 2005 and 2014 were assessed. The physical fitness questionnaire - Fitnessfragebogen (FFB-Mot) - was evaluated.

Failed Attempt to Recommend Noise Cancelling Headphones for Knee Arthroplasty Surgeons-Results of a Pilot Study.

: Noise exposure during total knee arthroplasty (TKA) has been demonstrated to exceed thresholds that are deemed as over-exposure by industry noise level standards. With orthopedic surgeons being at risk of suffering from Noise Induced Hearing Loss, the purpose of this pilot study was to evaluate the viability of the use of industry grade active noise cancelling headphones (ANCH) during TKA. In this prospective pilot study, 10 TKA were performed.

Distal Nerve Transfers in High Peroneal Nerve Lesions: An Anatomical Feasibility Study.

The peroneal nerve is one of the most commonly injured nerves of the lower extremity. Nerve grafting has been shown to result in poor functional outcomes. The aim of this study was to evaluate and compare anatomical feasibility as well as axon count of the tibial nerve motor branches and the tibialis anterior motor branch for a direct nerve transfer to reconstruct ankle dorsiflexion.

Double screw versus angular stable plate fixation of scaphoid waist nonunions in combination with intraoperative extracorporeal shockwave therapy (ESWT).

Introduction: Over the past years, different fixation techniques focused on rotational stability in order to increase stability and stimulate union rates. Additionally, extracorporeal shockwave therapy (ESWT) has gained importance in the treatment of delayed and nonunions. Purpose of this study was to compare the radiological and clinical outcome of two headless compression screws (HCS) and plate fixation in scaphoid nonunions, in combination with intraoperative high energy ESWT.

Artificial intelligence algorithms predict the efficacy of analgesic cocktails prescribed after orthopedic surgery.

Background: Mixtures ('cocktails') of various analgesics are more effective in controlling post-operative pain because of potential synergetic effects. Few studies have investigated such effects in large combinations of analgesics and no studies have determined the probabilities of effectiveness.

Methods: We used one-hot encoding of the categorical variables reported pain levels and the administered cocktails (from a total of eight analgesics) and then applied an unsupervised neural network and then the unsupervised DBSCAN algorithm to detect clusters of cocktails.

Lateral para-olecranon approach: surgical guide and anatomical considerations to the anconeus branch: is there a nerve-free zone?

Purpose: In the last decades, total elbow arthroplasty, elbow osteosynthesis and revision surgery have been more popularized. The study aimed to assess the course of the anconeus branch of the radial nerve in relation to two variations of the lateral para-olecranon approach, considering iatrogenic nerve injuries.

Methods: The study consisted of 120 upper extremities from 60 Thiel-embalmed human specimens.

Neurocognitive correlates of probable posttraumatic stress disorder following traumatic brain injury.

Introduction: Neurocognitive problems associated with posttraumatic stress disorder (PTSD) can interact with impairment resulting from traumatic brain injury (TBI).

Research Question: We aimed to identify neurocognitive problems associated with probable PTSD following TBI in a civilian sample.

Material And Methods: The study is part of the CENTER-TBI project (Collaborative European Neurotrauma Effectiveness Research) that aims to better characterize TBI.

Cost-Effectiveness of Cement Augmentation Versus No Augmentation for the Fixation of Unstable Trochanteric Fractures.

Background: A previous randomized controlled trial (RCT) demonstrated a trend toward a reduced risk of implant-related revision surgery following fixation with use of a Proximal Femoral Nail Antirotation (PFNA) with TRAUMACEM V+ Injectable Bone Cement augmentation versus no augmentation in patients with unstable trochanteric fractures. To determine whether this reduced risk may result in long-term cost savings, the present study assessed the cost-effectiveness of TRAUMACEM V+ cement augmentation versus no augmentation for the fixation of unstable trochanteric fractures from the German health-care payer's perspective.

Methods: The cost-effectiveness model comprised 2 stages: a decision tree simulating clinical events, costs, and utilities during the first year after the index procedure and a Markov model extrapolating clinical events, costs, and utilities over the patient's lifetime.

No component loosening of a cementless deep dish rotating platform knee at a 5-year follow-up.

Purpose: Cemented fixation remains the gold standard in total knee arthroplasty. With an increasing number of younger patients undergoing total knee arthroplasty and a growing patient population demanding higher physical activity, a rising interest in discussion of cementless fixation is notable. The current scientific literature does not give a clear recommendation for or against uncemented total knee arthroplasty.

Computed Tomography and Pathobiomechanical-Based Treatment of Volar Distal Radius Fractures.

Today, there are various classifications for distal radius fractures (DRF). However, they are primarily based on plain radiographs and do not provide sufficient information on the best treatment option. There are newer classifications that simultaneously consider the pathobiomechanical basis of the fracture mechanism and analysis of computed tomography images.

Health care utilization and outcomes in older adults after Traumatic Brain Injury: A CENTER-TBI study.

Introduction: The incidence of Traumatic Brain Injury (TBI) is increasingly common in older adults aged ≥65 years, forming a growing public health problem. However, older adults are underrepresented in TBI research. Therefore, we aimed to provide an overview of health-care utilization, and of six-month outcomes after TBI and their determinants in older adults who sustained a TBI.

Mini-open carpal tunnel release: technique, feasibility and clinical outcome compared to the conventional procedure in a long-term follow-up.

We sought to evaluate the findings of our anatomically landmarks based mini-open procedure (MCTR) through a palmar approach and to compare its outcome and practicability to the conventional method (OCTR). The study consisted of 100 matched patients (n = 50 MCTR, n = 50 OCTR) with a minimum follow-up of three years. The outcome was characterized via the Disabilities of Arm, Shoulder and Hand Score (DASH), Symptom Severity Scale (SSS), Functional Status Scale (FSC), and Visual Analogue Scale (VAS).

Purpose: To investigate a multivariate model to predict the individual risk of recurrent LPD.

Study Design: Case-control study; Level of evidence, 3.

Management of Coagulopathy in Bleeding Patients.

Early recognition of coagulopathy is necessary for its prompt correction and successful management. Novel approaches, such as point-of-care testing (POC) and administration of coagulation factor concentrates (CFCs), aim to tailor the haemostatic therapy to each patient and thus reduce the risks of over- or under-transfusion. CFCs are an effective alternative to ratio-based transfusion therapies for the correction of different types of coagulopathies.
