Coronoid fractures and complex elbow instability: current concepts.

Fractures of the coronoid process typically occur as part of more complex injury patterns, such as terrible triads, trans-olecranon fracture-dislocations, posteromedial rotatory injuries or Monteggia-like lesions. Each pattern is associated with a specific type of coronoid fracture with regard to shape and size and specific soft-tissue lesions. O' Driscoll classification incorporates those associations identifying three major types of fractures: tip, anteromedial facet, and basal fractures.

The impact of glenoid parameters and implant overstuffing on functional outcomes of shoulder hemiarthroplasty in patients with glenohumeral joint arthritis.

Purpose: The outcomes of shoulder hemiarthroplasty are highly dependent on the baseline glenoid morphology and the rotator cuff integrity. The objective of this study was to assess whether certain glenoid parameters and implant overstuffing are associated with worse clinical outcomes following shoulder hemiarthroplasty.

Methods: We retrospectively reviewed 25 patients who underwent shoulder hemiarthroplasty for shoulder arthritis, with a mean follow-up of 5.

A Scoping Review of the Recent Clinical Practice Regarding the Evaluation of Bone Mineral Density in Children and Adolescents with Neuromuscular Diseases.

Neuromuscular Diseases (NMD) are associated with decreased bone strength due to altered muscle-bone interaction. However, the evaluation of bone quality remains a certain challenge in these patients. The purpose of this scoping review is to investigate the recent literature regarding the assessment of Bone Mineral Density (BMD) in this population.

A staged procedure for the treatment of chronic patellar tendon ruptures after total knee arthroplasty.

The management of extensor mechanism lesions after total knee replacement is still associated with an unacceptably high complication rate, especially in its chronic setting. In this study, we report on 4 patients with chronic (> 3 months) patellar tendon rupture after knee arthroplasty, who were treated with a novel procedure of staged patella advancement prior to reconstruction with autografts. Initially, a unilateral frame was applied connecting the patella with the tibial shaft.

Interobserver Reliability of Schatzker, AO Foundation-Orthopaedic Trauma Association, and Luo Classifications for Tibial Plateau Fractures: Does Three-Dimensional CT Improve Outcomes?

Objective To assess the interobserver agreement of the most widely used classification systems (Schatzker, AO Foundation-Orthopaedic Trauma Association (AO-OTA), and Luo) and investigate the impact of multiplane CT scans on their reliability. Methods Twelve raters (seven consultants and five senior trainees) were invited to classify 25 cases of tibial plateau fracture randomly selected out of a large database. Initially, they were asked to classify the fracture according to Schatzker, AO-OTA, and Luo based on plain anteroposterior (AP) X-ray and axial CT images.

Efficacy and safety of tranexamic acid in hip fracture surgery. How does dosage affect outcomes: A meta-analysis of randomized controlled trials.

Aim: The objective of this study was to assess the efficacy and safety of intravenous TXA administration in elderly patients undergoing hip fracture surgery focusing on the effect of various dosages.

Methods: A systematic search of PubMed, Embase and Cochrane Library was conducted until February 2021. Our primary outcome was peri‑operative total blood loss, while secondary outcomes included transfusion rate, mean count of transfused RBC units and thromboembolic events' incidence.

Total Hip Replacement in Developmental Hip Dysplasia: A Narrative Review.

The reconstruction of the hip joint in patients suffering from developmental hip dysplasia (DDH) is a demanding procedure and presents many challenges to the reconstructive surgeon. Higher rates of mechanical complications are present in this group of patients. The results of cemented and uncemented implants used in DDH patients are very promising, according to recent outcomes.

Single dose of tranexamic acid effectively reduces blood loss and transfusion rates in elderly patients undergoing surgery for hip fracture: a randomized controlled trial.

Aims: The aim of this study was to investigate the hypothesis that a single dose of tranexamic acid (TXA) would reduce blood loss and transfusion rates in elderly patients undergoing surgery for a subcapital or intertrochanteric (IT) fracture of the hip.

Methods: In this single-centre, randomized controlled trial, elderly patients undergoing surgery for a hip fracture, either hemiarthroplasty for a subcapital fracture or intramedullary nailing for an IT fracture, were screened for inclusion. Patients were randomly allocated to a study group using a sealed envelope.

Reconstruction of the forearm interosseous membrane: a biomechanical study of three different techniques.

Reconstruction of the interosseous membrane has the potential to re-establish a normal loading pattern through the forearm and enhance stability after an Essex-Lopresti lesion. The aim of our study was to assess the capacity of three different techniques, which all use a regionally harvested autograft, to restore longitudinal stability. Simulation of the Essex-Lopresti lesion was done by excising the radial head and sectioning the interosseous membrane in seven cadaveric specimens.

Essex-Lopresti injuries: an update.

Reconstruction of the central band of the interosseous membrane is an emerging procedure implemented in the treatment of longitudinal radioulnar dissociation (LRUD), usually in its chronic setting, after Essex-Lopresti injuries of the forearm.There are no sufficient clinical data to support reconstruction of the central band of the interosseous membrane in acute LRUD injuries.Clinical and cadaveric studies comparing autografts (palmaris longus, flexor carpi radialis and bone-patellar-bone), allografts (Achilles tendon) and synthetic ligaments have not shown superiority of one technique another; however, they have shown special concerns with respect to the use of synthetic grafts.

Central band reconstruction for the treatment of Essex-Lopresti injury : A novel technique using the brachioradialis tendon.

Longitudinal stability of the forearm is mainly provided by three structures: the radiocapitellar contact, which acts as the primary stabilizer, the central band of the interosseous ligamentous complex (IOLC) and the intact triangular fibrocartilage complex (TFCC). In an Essex-Lopresti lesion the forearm becomes fully destabilized, since all of these three components are injured. Fixation or replacement of the radial head with a metallic prosthesis along with repair of the TFCC and stabilization of the distal radioulnar joint (DRUJ) are well-established treatment goals.
