Reverse Shoulder Arthroplasty: Evaluation of the Clinical and Functional Outcomes per Etiology.

 The present study aimed to evaluate the clinical outcomes of reverse shoulder arthroplasty to treat several conditions.  Retrospective, longitudinal study analyzing the Constant and University of California at Los Angeles (UCLA) scores and range of motion of patients undergoing reverse shoulder arthroplasty.  In total, 28 patients were analyzed, with a mean age of 75.

Arthroscopic Treatment of Rotator Cuff Rupture in Patients Under 55 years Old versus Patients Older than 65 Years Old.

 To evaluate patients submitted to arthroscopic repair of the rotator cuff (RC) comparing the results of muscle, functional strength, and pain obtained in 2 distinct groups: patients < 55 years old (G55) and patients > 65 years old (G65).  Data collection was performed with 63 participants (29 < 55 years old and 34 > 65 years old), in 2 moments, analyzing: A) demographic, surgical and RC lesion characteristics; B) functional variables, muscle strength, and pain.  Higher levels of anterior elevation force, lateral, and medial rotation of the operated shoulder were observed in group G55.

Arthroscopic Repair of Rotator Cuff Injury: An Analysis of Function, Muscular Strength and Pain Between Single Row and Double Row Techniques.

 To evaluate the patients submitted to arthroscopic repair of the rotator cuff (RC), comparing the functional results, muscle strength, and pain obtained after single row (SR) and double row (DR) techniques.  Data were collected at the postoperative follow-up (minimum of 12 months) of 128 patients submitted to arthroscopic RC repair from 2011 to 2018. The clinical-functional variables were collected through the clinical examination, and the demographic, surgical and injury variables of the RC were collected from the electronic medical records.

CLINICAL EVALUATION OF THE TREATMENT OF CLAVICLE FRACTURES: INTRAMEDULLARY NAIL × PLATE.

Objective: Studies confirm the benefit of surgical treatment for fixation of displaced midshaft clavicle fractures. Plate fixation and intramedullary nail are the two most used techniques. Our study seeks to compare these two surgical techniques.

Postoperative Comparative Evaluation of Patients Undergoing Surgical Treatment for Acute Versus Chronic Acromioclavicular Dislocations.

 The present study evaluates and compares the surgical treatment of acute and chronic acromioclavicular dislocations (ACDs) to define the most effective therapeutic plan.  A retrospective study consisting of 30 patients submitted to the surgical treatment of types III and V ACDs between 2011 and 2018; the subjects were separated according to a temporal classification in acute (< 3 weeks; subgroup I) and chronic (> 3 weeks; subgroup II) subgroups. All patients underwent a postsurgical evaluation with a standardized protocol containing epidemiological, functional, and radiological data.

Postoperative Evaluation of Patients Submitted to Arthroscopic Repair of Anterior Shoulder Instability.

 To clinically evaluate the results of patients undergoing arthroscopic surgical treatment of anterior shoulder instability.  A retrospective study of 94 patients. With a minimum follow-up of 24 months, we sought to correlate the characteristics of the patients and the surgery, such as age, gender, type of injury (traumatic or atraumatic) and the patient's position during surgery (lateral decubitus and beach chair) with the results obtained, the recurrence rate, the lateral rotation loss, the residual pain, and the functional scores of Carter-Rowe, University of California at Los Angeles (UCLA), and Constant-Murley.

Functional outcome after arthroscopic repair of triple shoulder instability.

Objective: To evaluate the functional outcomes of patients submitted to arthroscopic repair of triple labral lesion.

Methods: This was an analytical retrospective study of patients who underwent arthroscopic treatment of triple labral lesion from March 2005 to December 2014. Patients with at least one year of postoperative follow-up were included.
