Background: The incidence of complications associated with locked plating of proximal humerus fractures (PHF) has been reported in up to 40% of surgeries. This study aimed to analyze the incidence and risk factors of complications and re-intervention associated with locked plating of PHF in a an young active working population.
Methods: This retrospective cohort study included patients indicated for locked plating of displaced PHF at a dedicated workers' accident trauma center.
Introduction: The primary objective of this study was to assess the incidence of recurrent glenohumeral instability in patients over 40 years with isolated rotator cuff (RC) repair for traumatic shoulder dislocation. The secondary objectives were to identify risk factors for glenohumeral recurrence after RC repair and to describe the causes and incidences of re-intervention.
Materials And Methods: In this retrospective cohort study, data of consecutive patients at a single trauma center between January 2014 and July 2019 were reviewed, and 84 patients with a mean age of 57 (range: 40-75) years and follow-up duration of 3.
Background: There is no standardized therapeutic strategy for locked posterior shoulder fracture-dislocation (PSFD), and no consensus exists on the analysis of preoperative factors. This retrospective study aimed to evaluate functional results and complications in a series of PSFD cases managed with open surgical treatment.
Methods: Patients diagnosed with locked PSFD who underwent open surgical treatment with reduction and osteosynthesis between April 2016 and March 2020 were included.
Background: Optimal postoperative distalization (DSA) and lateralization (LSA) shoulder angles have been described as radiological measurements correlated with function after reverse shoulder arthroplasty (RSA). The proposed optimal values are DSA between 40° and 65° and LSA between 75° and 95°; however, whether these values can be reached with different implant designs is unclear.
Aim: To determine which RSA implant could achieve higher rates of optimal DSA and LSA, to determine any association between each implant and optimal DSA and LSA, and to assess the correlation of the preoperative critical shoulder angle (CSA) and acromial index (AI) with the DSA and LSA.
Purpose: The research aim was to determine the prevalence and risk factors of early secondary acromioclavicular (AC) joint disease in patients undergoing acute arthroscopic AC joint reduction and fixation and early complications of acute surgical treatment in patients with high-grade AC joint dislocation.
Methods: Overall, 102 patients diagnosed with Rockwood type V AC joint dislocation and undergoing arthroscopic coracoclavicular fixation were included. Early clinical and radiological complications were evaluated, as well as risk factors of secondary AC joint pathology.
Introduction: The shoulder terrible triad (STT) is a traumatic anterior shoulder dislocation, associated with rotator cuff (RC) tear and nerve injury from the brachial plexus. This study aimed to describe the functional results and prognostic factors of surgery in patients with STT.
Methods: Thirty consecutive patients with acute STT were included at the same institution.
Introduction There is a lack of information about the results of surgical treatment and complications in midshaft clavicle fracture non-unions. Our hypothesis was that there is no difference in functional outcomes between the surgical treatment of an acute displaced middle-third clavicle fracture and the surgical treatment of a chronic symptomatic non-union of a displaced middle-third clavicle fracture. Methods This was a case-control study.

Multiple techniques have been described to achieve reduction and fixation of the AC joint, but still there is no consensus. The objective of this Technical Note is to describe the reduction and internal fixation under arthroscopic assistance of the AC joint with the use of a double button implant plus high-strength tape in the acute setting.

Methods: The study randomized 76 consecutive patients with displaced fractures (2B1-2B2 according to Robinson) to conservative (C, n = 42) and surgical (S, n = 34) treatment with plates and screws. Bone union was documented with CT scans at 6 and 12 weeks.
Objective: To determine the incidence, nature, and causes of match injuries sustained during Under-20 (U-20) international rugby.
Design: Prospective cohort study; definitions and procedures were compliant with the international consensus statement for epidemiological studies in rugby.
Setting: 2008 and 2010 IRB U-20 Junior World Championships and Junior World Rugby Trophies.
