FRACTURE-DISLOCATIONS OF THE ELBOW: CAN THEY INFLUENCE THE PATTERN FRACTURE OF RADIAL HEAD?

Introduction: Radial head fractures are consistently part of a terrible triad of the elbow and can occur in association with Monteggia fracture-dislocations, transolecranon fractures, and their variations. Understanding the degree of comminution of the radial head fracture and the location of fragments determines the course of action to be taken.

Objectives: To correlate fracture-dislocations with the pattern of radial head fracture (number of fragments) and involvement in the proximal radioulnar region.

COMPLICATIONS AFTER SURGICAL TREATMENT OF JUPITER'S MONTEGGIA TYPE II FRACTURES.

Unlabelled: Monteggia fracture-dislocations are rare injuries, affecting about 2-5% of the population. Jesse Jupiter subdivided Bado's Type II fractures into four types, all of which presented an associated radial head fracture. Associated chondral and ligament injuries can evolve with postoperative complications.

The Hertel classification can't predict the risk of humeral head osteonecrosis after osteosynthesis using an anterolateral approach.

Background: Proximal humeral fractures can progress to osteonecrosis of the humeral head. Hertel developed a binary classification system (12 subtypes) and demonstrated that some patterns have more risk to develop osteonecrosis. Hertel described the prevalence and the risk factors for Humeral head osteonecrosis after osteosynthesis using a Deltopectoral approach.

Prevalence and risk factors for pseudarthrosis in humeral shaft fractures treated by minimally invasive plate osteosynthesis: A 10-year review.

Introduction: Fractures of the humeral shaft account for about 3% to 5% of all fractures. Although conservative treatment remains the first choice, there are a number of surgical indications. Minimally invasive plate osteosynthesis shows good functional results.

MORTALITY AFTER SURGICAL TREATMENT OF PROXIMAL HUMERUS FRACTURES IN OLDER PATIENTS.

Unlabelled: Mortality of patients after osteosynthesis of proximal humeral fractures (PHF) has been poorly studied in contrast to fractures of the proximal femur.

Objective: To evaluate the mortality of older patients with PHF undergoing surgical treatment.

Methods: Retrospective study of patients undergoing surgical treatment PHF between 2009-2019.

ANTEROLATERAL APPROACHES FOR PROXIMAL HUMERAL OSTEOSYNTHESIS: A SYSTEMATIC REVIEW.

Objective: Anterolateral approaches for proximal humerus osteosynthesis have great advantages because they allow direct exposure of the lateral aspect of the humerus without the muscular retraction seen in the deltopectoral approach. However, much resistance is found among surgeons due to the potential risk of iatrogenic injury to the axillary nerve. To identify the incidence of axillary nerve iatrogenic lesions and evaluate the functional results of proximal humerus osteosynthesis with locking plates using anterolateral approaches.

PROXIMAL HUMERAL FRACTURES TREATED WITH OSTEOSYNTHESIS USING THE ANTEROLATERAL APPROACH.

Objective: The main surgical approach in proximal humeral fractures is the deltopectoral approach. Many surgeons avoid the anterolateral approach, fearing its complications, especially axillary nerve injury. The objective of this study is to evaluate shoulder function and complications in patients with proximal humeral fractures treated using an anterolateral approach with direct observation of the axillary nerve.

EVALUATION OF CHILDREN WITH RADIAL NECK FRACTURES TREATED WITH FLEXIBLE INTRAMEDULLARY NAIL.

Objective: : To evaluate the results of displaced radial neck fractures in children trated surgically with flexible titanium intramedullary nails.

Method: : This is a retrospective study of five cases of radial neck fractures with displacement greater than 30° fixed with flexible intramedullary nails. Patients were evaluated regarding functional outcome through range of motion and the Mayo Elbow Performance Score (MEPS), as well as radiographic exams.

Functional evaluation of patients with surgically treated terrible triad of the elbow.

Objectives: To evaluate the functional outcome of patients with surgically treated terrible triad of the elbow.

Methods: A retrospective evaluation was performed using the MEPS score (Mayo Elbow Performance Score) of patients diagnosed with terrible triad of the elbow who underwent surgical treatment.

Results: 14 patients (nine men and five women) and 15 elbows (one bilateral case) were evaluated.

Fracture of distal humerus: MIPO technique with visualization of the radial nerve.

Objectives: To evaluate the outcomes in patients treated for humerus distal third fractures with MIPO technique and visualization of the radial nerve by an accessory approach, in those without radial palsy before surgery.

Methods: The patients were treated with MIPO technique. The visualization and isolation of the radial nerve was done by an approach between the brachialis and the brachiorradialis, with an oblique incision, in the lateral side of the arm.
