No difference in early functional outcome between the direct anterior approach and posterior approach in patients following total hip arthroplasty.

Background: Objective and subjective outcomes in the direct anterior approach (DAA) and posterior approach (PA) in total hip arthroplasty (THA) were assessed in this study, using the Oxford Hip Score (OHS) as primary outcome. Pain, 3 objective performance-based tests, surgical time, blood loss and length of stay were assessed as secondary outcomes.

Methods: Patients with primary end-stage osteoarthritis were prospectively enrolled by shared decision making for the DAA (32 patients) or PA (26 patients).

Giant Congenital Left Atrial Appendage Aneurysm Presenting With Recurrent Supraventricular Tachycardia and Chest Pain.

• LAAA is a rare anomaly characterized by appendage enlargement. • Clinical presentations of LAAA range from asymptomatic to life threatening. • Multimodality imaging, including TTE, is the mainstay of diagnosis.

Circulating Biomarkers Predictive of Postoperative Atrial Fibrillation.

Postoperative atrial fibrillation (PoAF), a common complication of cardiac surgery, contributes significantly to morbidity, mortality, and increasing healthcare costs. Despite advances in surgical and medical management, the overall incidence of PoAF has not changed significantly, partly because of the limited understanding of mechanisms underlying acute surgery-related factors, such as myocardial injury, inflammation, sympathetic activation, and oxidative stress, which play an important role in the initiation of PoAF, whereas a preexisting atrial substrate appears to be more important in the maintenance of this dysrhythmia. Thus, in a majority of patients, PoAF becomes a manifestation of an underlying arrhythmogenic substrate that is unmasked after acute surgical stress.

Basic principles and uniform terminology for the head-neck junction in hip replacement.

Recent problems with large head metal on metal hip replacements have spiked renewed interest in the head-neck junction. A thorough knowledge of the principles of the locking mechanism, the assembly technique and affecting factors on the strength of this junction is needed. Currently a confusing variability in terms is used to describe this junction.

Primary uncemented hemiarthroplasty for severe fractures of the proximal humerus.

Objectives: The purpose of this study is to evaluate a consecutive series of proximally porous-coated hemiarthroplasty for the treatment of severe proximal humeral fractures with special emphasis on aseptic loosening and functional outcome.

Design: Observational cohort of a consecutive series of a single prosthetic design.

Setting: Orthopaedic clinic, nonacademic institutional hospital.

Alternative humeral tubercle fixation in shoulder hemiarthroplasty for fractures of the proximal humerus.

Hypothesis: We hypothesize that the sling technique provides better long term tuberosity fixation in hemiarthroplasty for severe fractures of the proximal humerus.

Background: After hemiarthroplasty for proximal humeral fractures, problems exist with deterioration of shoulder function by secondary displacement of the initially fixated humeral tuberosities. This study evaluated a new technique for fixation of the greater and lesser tuberosities in uncemented hemiarthroplasties in severely displaced 3- or 4-part proximal humeral fractures.
