Medial placement of trapezoid tunnel leads to higher reduction loss in acute acromioclavicular joint dislocation treated with anatomic coracoclavicular fixation.

Aim: To analyze the association between clavicular tunnel positioning and postoperative reduction loss in patients with acute acromioclavicular (AC) joint dislocation treated with anatomic coracoclavicular (CC) fixation using double clavicular tunnels.

Methods: A retrospective review of patients with AC joint dislocation, treated with anatomic CC fixation using double clavicular tunnels, was conducted. Patients with pre-operative, immediate post-operative, and final follow-up Zanca-view X-rays were included.

[Anterior shoulder instability with Hill-Sachs on-track. Bankart or Bankart-remplissage?].

Introduction: in patients with anterior glenohumeral (GH) instability together with an off-track or engaging Hill-Sachs (HS) defect, Bankart-remplissage (B-R) surgery reduces the recurrence rate when compared to Bankart (B) surgery alone. There is controversy regarding whether the recurrence rate also decreases in patients with on-track or non-engaging Hill-Sachs defects.

Objective: to compare the recurrence rate and clinical evolution of patients with anterior glenohumeral instability with 'on-track' Hill-Sachs defect treated with either B or B-R surgery.

Anatomic coracoclavicular ligament reconstruction with triple flip-buttons leads to good functional outcomes and low reduction loss: a case series.

Background: The management of acromioclavicular (AC) joint dislocation remains controversial. Recently, anatomic coracoclavicular (CC) fixation with a double clavicular tunnel and three flip-buttons has shown promising results. This study aimed to evaluate functional and radiological outcomes in patients with high-grade AC joint dislocation treated with anatomic CC fixation using double clavicular tunnels and three flip-buttons.

[Implementation of diagnosis related groups methodology in a university hospital].

Background The Diagnosis Related Groups (DRG) constitute a method of classifying hospital discharges. Aim To report its development and implementation in a Chilean University Hospital and global results of 10 years Material and Methods We included 231,600 discharges from 2007 to 2016. In the development we considered the physical plant, clinical record flow, progressively incorporated human resources and computer equipment for coding and analysis to obtain results.

Efficacy and safety profile of vismodegib in a real-world setting cohort of patients with advanced basal cell carcinoma in Argentina.

Introduction And Objectives: Vismodegib (Erivedge ), a hedgehog pathway inhibitor, is approved to treat metastatic or locally advanced basal cell carcinoma (BCC) not suitable for surgery or radiotherapy. Our main objectives were to study the objective response rate (ORR) assessed by treating physicians and safety of vismodegib in a real-world practice setting in Argentina.

Material And Methods: This is a prospective cohort study in real-world practice.
