Uncemented reverse total shoulder arthroplasty: is it a safe option for elderly patients with proximal humerus fractures?

Purpose: Reverse shoulder arthroplasty (RSA) is a common surgical procedure for elderly patients with proximal humerus fractures. Cement fixation of the humeral stem is considered the gold standard for this procedure. Due to the high prevalence of osteoporosis in this patient population, the risk of intraoperative fractures is increased when uncemented stems are used.

Combined Anteversion Threshold to Avoid Anterior Dislocation in Primary Total Hip Arthroplasty Performed Through the Direct Anterior Approach.

Background: Component malposition in total hip arthroplasty (THA) can lead to dislocation, early implant failure, and revision surgery. As the surgical approach might affect the targeted combined anteversion (CA) of THA components, the present study aimed to evaluate the optimal CA threshold to avoid anterior dislocation in primary THA performed through a direct anterior approach (DAA).

Methods: A total of 1,176 THAs in 1,147 consecutive patients (men: 593, women: 554) who had an average age of 63 years (range, 24 to 91) and a mean body mass index of 29 (range, 15 to 48) were identified.

A novel method for evaluating combined component anteversion in total hip arthroplasty on cross-table lateral hip radiographs.

Introduction: Accurate measurement of combined component anteversion (CA) is important in evaluating the radiographic outcomes following total hip arthroplasty (THA). The aim of the present study was to evaluate the accuracy and reliability of a novel radiographic method in estimating CA in THA.

Materials And Methods: The radiographs and computer tomography of patients who underwent a primary THA were retrospectively reviewed, to measure the radiographic CA (CAr), defined as the angle between a line connecting the center of the femoral head to the most anterior rim of the acetabular cup and a line connecting the center of the femoral head to the base of the femoral head to allow a comparison with the CA measured on the CT (CACT).

Superior humeral head migration might be a radiological aid in diagnosing patients with adhesive capsulitis of the shoulder.

Background: The diagnosis of adhesive capsulitis (AC) of the shoulder might be challenging, as it is a diagnosis of exclusion and mainly based on the clinical examination. The purpose of the present study was to investigate the validity and reliability of 4 commonly reported radiological parameters suggesting a superior humeral head migration on anteroposterior (a/p) shoulder radiograph in identifying patients with AC.

Methods: The a/p shoulder radiographs of 100 patients with AC and 100 control subjects were retrospectively reviewed.

Appendiceal stump closure with polymeric clips is a reliable alternative to endostaplers.

Objective: Polymeric (Hem-o-lok) clips represent a novel technique with which to ligate the appendiceal stump following laparoscopic appendectomy. We compared the outcomes of using polymeric clips versus endostaplers for complicated and uncomplicated appendicitis.

Methods: Six hundred seventy-three consecutive patients undergoing laparoscopic appendectomy with polymeric clips or endostaplers for acute appendicitis were assessed.
