Objective: Heterotopic ossification is defined as the formation of trabecular bone in soft tissues. It is a common complication after surgical treatment of acetabular fractures. However, its prophylaxis and treatment are still controversial.

Total hip arthroplasty versus hemiarthroplasty for displaced femoral neck fracture: a protocol for an overview of systematic reviews.

Introduction: Hip arthroplasties for the treatment of displaced femoral neck fractures in adults can be total replacement or hemiarthroplasty. Despite the high prevalence of these fractures and large number of studies on the topic, the best choice of arthroplasty to be used remains unclear. The present study aims to overview the results of systematic reviews of randomised controlled trials (RCTs) comparing outcomes between total hip replacement and hemiarthroplasty for displaced femoral neck fractures in adults.

Protocol of BRICS: Brazilian multicentric pragmatic randomised trial of surgical interventions for displaced diaphyseal clavicle fracture study: MIPO versus ORIF for the treatment of displaced midshaft clavicle fractures.

Introduction: Fractures of the diaphysis of the clavicle are common; however, treatment guidelines for this condition are lacking. Surgery is associated with a lower risk of non-union and better functional outcomes but a higher risk of complications. Open reduction and internal fixation with plates and screws are the most commonly performed techniques, but they are associated with paraesthesia in the areas of incisions, extensive surgical exposure and high rates of implant removal.

Diagnosis of Achilles Insertional Tendinopathies by Algometry.

Introduction: Diagnosis of Achilles insertional tendinopathies (AIT) is based on pain by tendon palpation. However, there is no consensus or standard with regard to the amount of force to be used during the evaluation. Algometry is a method of measuring the pressure applied in a specific region and can be a method for determining diagnosis values.

Treatment of Distal Radio Vicious Consolidation: Corrective Osteotomy Through 3D Printing Prototyping.

Distal radial fractures are very common. Vicious consolidation can occur in up to one third of these fractures, resulting in wrist pain, restricted movement, and, eventually, physical limitation or disability. The treatment of this condition consists in corrective osteotomy, which requires careful preoperative planning due to its three-dimensional complexity, especially in injuries with joint involvement.

How one treats lateral epicondylitis - a survey among Brazilian orthopedists.

Background: Lateral epicondylitis (LE), also known as tennis elbow, is the most common painful elbow condition. It affects approximately 1-3% of adults. There are various possible treatments described in the literature, but evidence to support a gold standard management protocol is lacking.

Shockwave Therapy Plus Eccentric Exercises Versus Isolated Eccentric Exercises for Achilles Insertional Tendinopathy: A Double-Blinded Randomized Clinical Trial.

Background: There remains a lack of consensus regarding the treatment of Achilles insertional tendinopathy. The condition is typically treated with eccentric exercises despite the absence of satisfactory and sustained results. Shockwave therapy was presented as an alternative, but there is a paucity of literature, with good outcomes, supporting its use.

Supraspinatus tears: predictability of magnetic resonance imaging findings based on clinical examination.

Background: The shoulder physical examination is frequently performed to diagnose rotator cuff tears in clinical practice; however, there is insufficient evidence on which physical tests are efficient for shoulder impingements in primary care settings. The purposes of this study were (1) to analyze the accuracy of 8 clinical tests to diagnose supraspinatus tendon lesions and investigate whether the combination of these tests can improve the diagnostic values; (2) to assess which are the best positivity criteria for shoulder maneuvers-pain and/or weakness; and (3) to investigate the ability of these tests to distinguish between partial- and full-thickness tears.

Methods: A total of 733 consecutive patients were prospectively evaluated by 4 shoulder surgeons in this multicenter diagnostic study from May 2017 to December 2018, and 8 clinical tests (empty-can, full-can test, drop arm, painful arc, Neer sign, Hawkins test, Patte test, and resisted external rotation) were compared with magnetic resonance imaging performed by blinded radiologists.

Does Biceps Tenotomy or Tenodesis Have Better Results After Surgery? A Systematic Review and Meta-analysis.

(2) Which approach has superior results when evaluating function outcome (Constant) scores? (3) Does tenotomy or tenodesis have fewer complications? (4) Does tenotomy or tenodesis result in better cosmesis (Popeye sign)?

Methods: A systematic review was performed in the Cochrane Library, Embase, PubMed, and Literatura Latino Americana e do Caribe em Ciências da Saúde (LILACS) using the keywords "long head of the biceps tendon," "biceps tenodesis," and "tenotomy." We completed the search in June 2020.

Achilles Tendon Lesions - Part 2: Ruptures.

The increasing incidence of calcaneal tendon ruptures has substantially impacted orthopedic care and costs related to its treatment and prevention. Primarily motivated by the increasing of life expectancy, the growing use of tenotoxic drugs and erratic access to physical activity, this injury accounts for considerable morbidity regardless of its outcome. In recent years, the evolution of surgical and rehabilitation techniques gave orthopedists better conditions to decide the most appropriate conduct in acute tendon rupture.

Achilles Tendon Lesions - Part 1: Tendinopathies.

Calcaneal tendon injuries are extremely common in the general population and in orthopedics routine care. Its increasing incidence, which is motivated by an aging population, improved access to the health care system, increased prescription of continuous-use medication, erratic participation in sports and other factors, has had a direct impact on society. Consolidated treatment options for tendinopathies lack quality scientific support for many modalities.

Glenoid failure after total shoulder arthroplasty with cemented all-polyethylene versus metal-backed implants: a systematic review protocol.

Introduction: Anatomical total shoulder arthroplasty (TSA) is an effective treatment adopted for patients with glenohumeral osteoarthritis (OA). The glenoid component failure is the main risk that occurs in this therapeutic choice; however, doubts remain regarding the selection of the best implant for avoiding complication. This systematic review aims to evaluate the glenoid component in TSA by comparing the complications of different types of implants.

ACHILES: AN IMORTAL EPONYMOUS.

Unlabelled: The conditions affecting the calcaneal tendon remain extremely prevalent in the clinical practice. The search for information about these diseases in national and international scientific databases are commonly hampered in the use of search tools, requiring the use if an eponym in the strategy. Achilles, in reference to the hero of the Greek mythology, is often used by several authors in scientific publications despite the new Nomina Anatomica.

Crossed versus lateral K-wire fixation of supracondylar fractures of the humerus in children: a meta-analysis of randomized controlled trials.

Background: Supracondylar fractures of the humerus are common in children. Whether fixation should be performed with crossed or lateral wires remains controversial. We performed a meta-analysis of randomized controlled trials to evaluate both techniques in terms of the function of the elbow and the risk of neurologic injury and loss of reduction.
