More Anteromedial Coronoid Involvement in Combined Fractures of the Coronoid and Radial Head Than Traditional Teaching.

Background: The terrible triad injury involves an ulnohumeral dislocation, radial head fracture, and coronoid process fracture. According to traditional teaching, these injuries are strongly associated with anterolateral coronoid tip fractures and can be addressed via a lateral approach to the elbow. However, recent small clinical series suggest that some terrible triad injuries have larger coronoid fractures involving the anteromedial facet.

Pediatric Patients Who Underwent Elbow Arthroscopy Had an 86% Return-to-Sport Rate, a 12% Reoperation Rate, and a 3.7% Complication Rate.

Purpose: To assess the applicability and safety of elbow arthroscopy in the pediatric population at our institution by analyzing the indications and complications in a large pediatric patient series.

Methods: We retrospectively identified all patients who underwent elbow arthroscopy at age 18 years or younger from 2006 to 2017 performed by a single fellowship-trained surgeon. The exclusion criteria were follow-up shorter than 8 weeks and open surgical procedures (not fully arthroscopic).

Type of fixation is not associated with range of motion after operative treatment of proximal radius fractures- a systematic review of 519 patients.

Background: The aims of this study are 1) to assess whether open reduction internal fixation (ORIF) techniques for fractures of the proximal radius are associated with the range of motion (ROM), 2) to determine the incidence of hardware-related complications and removal following plate and screw fixation of the proximal radius, and 3) to evaluate whether the safe-zone definition is described in the literature and its relation to the ROM.

Methods: A literature search was performed in the PubMed, Embase, and Cochrane databases. Studies reporting ROM in patients undergoing ORIF for radial head or neck fractures were included.

Patient-Reported Outcome Measures Show No Relevant Change Between 1-Year and 2-Year Follow-Up After Treatment for Anterior Shoulder Instability: A Systematic Review.

Purpose: To compare patient-reported outcome measures (PROMs) at 1-year and 2-year follow-up after treatment for anterior shoulder instability.

Methods: Randomized controlled trials and prospective studies that evaluated and reported PROMs after a capsulolabral repair (with or without remplissage), bone augmentation, or nonoperative treatment to treat anterior shoulder instability at both 1-year and 2-year follow-up were included. PROMs were compared between 1-year and 2-year follow-up; forest plots with mean difference were created to compare baseline, 1-year, and 2-year follow-up; and scatterplots were created to visualize clinical improvement over time.

Substantial variability in what is considered important in the radiological report for anterior shoulder instability: a Delphi study with Dutch musculoskeletal radiologists and orthopedic surgeons.

Background: Standardized consensus-based radiological reports for shoulder instability may improve clinical quality, reduce heterogeneity, and reduce workload. Therefore, the aim of this study was to determine important elements for the x-ray, magnetic resonance imaging (MRI) arthrography (MRA), and computed tomography (CT) report, the extent of variability, and important MRI views and settings.

Methods: An expert panel of musculoskeletal radiologists and orthopedic surgeons was recruited in a three-round Delphi design.

Eponymous terms in acromioclavicular joint surgery.

Eponymization serves as a means of paying tribute to individuals who have made significant contributions to our culture. Each eponym is often linked with a story for everyone to discover. To aid in the retention of these stories, this review offers readers an overview of the individuals behind the eponymous terms, as well as their original descriptions, within the context of acromioclavicular joint pathology and orthopaedic surgery.

Developing a Rehabilitation Guideline (REGUIDE) for Patients Undergoing an Arthroscopic Bankart Repair After Traumatic Anterior Shoulder Dislocation, Focusing on Managing Apprehension: An International Delphi-Based Consensus Study.

We aimed to develop a consensus-based rehabilitation guideline specifically designed to reduce apprehension following arthroscopic Bankart repair after traumatic anterior shoulder dislocation. Delphi-based consensus. A comprehensive list of interventions for potential inclusion in a postoperative rehabilitation guideline was developed.

Statistical shape models that predict native glenoid width based on glenoid height are inaccurate in their current form: a cross-sectional study.

Background: The extent of measurement errors of statistical shape models that predict native glenoid width based on glenoid height to subsequently determine the amount of anterior glenoid bone loss is unclear. Therefore, the aim of this study was to (1) create a statistical shape model based on glenoid height and width measured on 3-dimensional computed tomography (3D-CT) and determine the accuracy through measurement errors and (2) determine measurement errors of existing 3D-CT statistical shape models.

Materials And Methods: A retrospective cross-sectional study included all consecutive patients who underwent CT imaging before undergoing primary surgical treatment of traumatic anterior shoulder dislocation between 2007 and 2022 at the Tohoku University Hospital and affiliated hospitals.

Minimal but potentially clinically relevant anteroinferior position of the humeral head following traumatic anterior shoulder dislocations: A 3D-CT analysis.

In unstable shoulders, excessive anteroinferior position of the humeral head relative to the glenoid can lead to a dislocation. Measuring humeral head position could therefore be valuable in quantifying shoulder laxity. The aim of this study was to measure (1) position of the humeral head relative to the glenoid and (2) joint space thickness during passive motion in unstable shoulders caused by traumatic anterior dislocations and in contralateral uninjured shoulders.

Treatment Outcomes of Simple Elbow Dislocations: A Systematic Review of 1,081 Cases.

Background: The treatment of simple elbow dislocations (SEDs) has become more functional last decade with a tendency to shorter immobilization of the elbow, whereas simultaneously, surgical stabilization has been promoted by some authors. The primary aim of this study was to systematically review the literature and analyze the outcomes and complications of different treatment options for acute and persistent SEDs, including operative and nonoperative treatments with varying immobilization periods.

Methods: A literature search was performed based on the online medical databases MEDLINE, Embase, and the Cochrane databases.

Ten technical aspects of baseplate fixation in reverse total shoulder arthroplasty for patients without glenoid bone loss: a systematic review.

The aim of this systematic review was to collect evidence on the following 10 technical aspects of glenoid baseplate fixation in reverse total shoulder arthroplasty (rTSA): screw insertion angles; screw orientation; screw quantity; screw length; screw type; baseplate tilt; baseplate position; baseplate version and rotation; baseplate design; and anatomical safe zones. Five literature libraries were searched for eligible clinical, cadaver, biomechanical, virtual planning, and finite element analysis studies. Studies including patients >16 years old in which at least one of the ten abovementioned technical aspects was assessed were suitable for analysis.

A modified Delphi study to identify which items should be evaluated in shoulder instability research: a first step in developing a core outcome set.

Background: The aim of this study was to identify items that healthcare providers and/or patients consider important to include in a questionnaire for clinical trials and cohort studies in shoulder instability research. This could serve as a basis to develop a core outcome set for shoulder instability research.

Methods: Healthcare providers and patients were included in a panel for a modified Delphi consensus study.

Coronoid fractures and traumatic elbow instability.

The coronoid process is key to concentric elbow alignment. Malalignment can contribute to post-traumatic osteoarthritis. The aim of treatment is to keep the joint aligned while the collateral ligaments and fractures heal.

High variability in what is considered important to report following instability surgery: a Delphi study among Dutch shoulder specialists.

Background: Standardized reporting leads to high-quality data and can reduce administration time. The aim of this study was to (1) get an insight into the variability of what is considered important to report in the surgical report following shoulder instability surgery and (2) determine which elements should be included in the surgical report following shoulder instability surgery according to Dutch surgeons using a Delphi method.

Methods: Dutch orthopedic shoulder surgeons were included in a panel for a Delphi study consisting of 3 rounds.

Comparisons of Routine Initial Operative Fracture Treatment and Later Reconstructive Treatment are not Interesting.

Studies that compare routine immediate operative treatment of fractures with selective later reconstructive surgery for malunion or nonunion may be misleading because it discounts the people who did well with nonoperative treatment. We identified 20 studies comparing routine operative fracture treatment and later reconstruction in the hip, clavicle, proximal humerus, elbow, and distal radius. Fifteen of 20 studies favored immediate operative treatment on the basis of lower reoperation rates, fewer complications, better patient reported outcome scores, and higher satisfaction.

Developing a machine learning algorithm to predict the probability of aseptic loosening of the glenoid component after anatomical total shoulder arthroplasty: protocol for a retrospective, multicentre study.

Introduction: Despite technological advancements in recent years, glenoid component loosening remains a common complication after anatomical total shoulder arthroplasty (ATSA) and is one of the main causes of revision surgery. Increasing emphasis is placed on the prevention of glenoid component failure. Previous studies have successfully predicted range of motion, patient-reported outcomes and short-term complications after ATSA using machine learning methods, but an accurate predictive model for (glenoid component) revision is currently lacking.
