Aims: This study aimed to answer the following questions: do 3D-printed models lead to a more accurate recognition of the pattern of complex fractures of the elbow?; do 3D-printed models lead to a more reliable recognition of the pattern of these injuries?; and do junior surgeons benefit more from 3D-printed models than senior surgeons? Methods:...

The coronoid process is key to concentric elbow alignment. Malalignment can contribute to posttraumatic osteoarthritis. The aim of treatment is to keep the joint aligned while the collateral ligaments and fractures heal. The injury pattern is apparent in the shape and size of the coronoid fracture fragments: 1) coronoid tip fractures associated wit...

Aims This study aimed to gather insights from elbow experts using the Delphi method to evaluate the influence of patient characteristics and fracture morphology on the choice between operative and nonoperative treatment for coronoid fractures. Methods A three-round electronic (e-)modified Delphi survey study was performed between March and Decembe...

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 tha...

Case A 7-year-old girl presented with an elbow terrible triad injury (coronoid fracture, Salter-Harris IV radial head fracture, and lateral collateral ligament avulsion) diagnosed after magnetic resonance imaging was obtained to evaluate subtle subluxation on radiographs. The patient underwent physeal-sparing fixation using the anconeus-extensor ca...

Background Literature on outcomes after reoperation for intra-articular proximal ulna fractures is lacking, even though reoperation rates for these fractures are reportedly one of the highest of any anatomic site, ranging from 22%-89%. This study aims to evaluate range of motion (ROM) and complication rates after reoperation for these fractures. M...

Aims The purpose of this study was to develop a convolutional neural network (CNN) for fracture detection, classification, and identification of greater tuberosity displacement ≥ 1 cm, neck-shaft angle (NSA) ≤ 100°, shaft translation, and articular fracture involvement, on plain radiographs. Methods The CNN was trained and tested on radiographs so...

The current methods of assessing tendon health such as clinical examination, imaging techniques, and implanted pressure sensors, are often based on a subjective assessment or are not accurate enough, are extremely expensive, or are limited to relatively large damage such as partial or gross tear of the tendon and cannot accurately assess and monito...

Background: Determining accurate intraoperative screw length in complex distal radius fractures may pose difficulties. With volar plate fixation, excessive screw length may result in extensor pollicis longus injury and this can be challenging to determine via intraoperative imaging. This study aims to identify the precise anatomic location and para...

Purpose To analyze the clinical and demographic presentation, treatment strategies, and outcomes of athletes who sustained proximal ulna stress injuries and elucidate the available evidence on management and anatomic variation. Methods A literature search was performed on the basis of the medical databases MEDLINE/PubMed and Embase. Articles repor...

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 wh...

The average mention rate for risk factors across studies reporting complication rates after elbow arthroscopy was 31%. Literature on elbow arthroscopy most often mentions non-modifiable risk factors. Future studies that report complication rates in elbow arthroscopy should include an evaluation of the presence of risk factors in their cohort. Repor...

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 complicat...

Posterior impingements are most commonly seen in athletes involved in overhead-throwing sports. It is also reported in boxing and lifting heavy objects. The whole kinetic chain involved in the sport of the athlete causing the symptoms should be examined. Only if nonsurgical treatment is unsuccessful does sur- gery needs to be considered. Arthroscop...

Osteochondritis dissecans of the capitellum is debilitating and is a potentially sports career-ending injury in a young and athletic population. Osteochondritis dissecans typically occurs in patients between the ages of 10 and 24 years, and boys are more commonly affected than girls. Conventional radiographs have low diagnostic accuracy, and magnet...

Purpose: To perform a systematic review of complications associated with elbow arthroscopy in adults and children. Methods: A literature search was performed in the PubMed, EMBASE, and Cochrane databases. Studies reporting complications or reoperations after elbow arthroscopy with at least five patients were included. Based on the Nelson- classifi...

The origins of contemporary orthopedics can be traced all the way back to antiquity. Despite the absence of modern imaging techniques, a few bright minds were able to lay the groundwork for understanding these fractures. This historical review will cover the process behind the various treatments for elbow fractures, such as splinting and casting, m...

Missed fracture diagnoses are common in pediatric patients and a major concern in orthopaedic care. Immature bone has unique composition and response to injury, manifesting in fracture patterns differing from adult equivalents. Torus (Buckle) fractures are an example of this in which missed diagnoses are common. Convolutional neural networks (CNNs)...

An imaging dataset of 1000 hand and wrist radiographs was compiled and annotated for the computer vision task of object detection on scaphoid injuries. The trained AI succeeded in detecting scaphoid fractures with 92.9% mAP, 86.1% precision, and 93.9% recall on a validation dataset of similar radiographs (n=200). A publicly available version of the...

- Primary osteoarthritis (OA) of the elbow can cause disabling symptoms of pain, locking, stiffness, and a limitation in the range of motion. There is no consensus regarding the role of open and arthroscopic debridement in the treatment of symptomatic primary elbow OA. The aim of this study is to systematically review the outcome of surgical debrid...
