Total Hip Arthroplasty Performed by Fellowship and Non-Fellowship Trained Surgeons: A Comparison of Indications, Perioperative Management and Complications.

Introduction: Adult reconstruction fellowship-trained (FT) surgeons undergo an additional year of dedicated subspecialized training. The benefits of fellowship training include a comprehensive understanding of arthroplasty patient care and contemporary surgical techniques, as well as an expanded network of mentors and colleagues. The purpose of the present study was to compare practice variations between FT and non-fellowship-trained (NFT) surgeons, focusing on indications, perioperative prescribing patterns, and complication rates surrounding total hip arthroplasty (THA).

2022 American College of Rheumatology/American Association of Hip and Knee Surgeons Guideline for the Perioperative Management of Antirheumatic Medication in Patients With Rheumatic Diseases Undergoing Elective Total Hip or Total Knee Arthroplasty.

Objective: To develop updated American College of Rheumatology/American Association of Hip and Knee Surgeons guidelines for the perioperative management of disease-modifying medications for patients with rheumatic diseases, specifically those with inflammatory arthritis (IA) and those with systemic lupus erythematosus (SLE), undergoing elective total hip arthroplasty (THA) or elective total knee arthroplasty (TKA).

Methods: We convened a panel of rheumatologists, orthopedic surgeons, and infectious disease specialists, updated the systematic literature review, and included currently available medications for the clinically relevant population, intervention, comparator, and outcomes (PICO) questions. We used the Grading of Recommendations Assessment, Development and Evaluation (GRADE) methodology to rate the quality of evidence and the strength of recommendations using a group consensus process.

Femoral Vessel Blood Flow Is Preserved Throughout Direct Anterior Total Hip Arthroplasty.

Posterolateral and anterolateral approach THA disrupts femoral vessel blood flow, however, this has not been established for the direct anterior (DA) approach. Ten patients undergoing primary DA THA had peak vascular flow rates for the femoral artery and vein calculated via Doppler ultrasound at specified points: incision, acetabular preparation, femoral preparation and final reduction. Peak femoral arterial and venous flow decreased over baseline, but not significantly, during acetabular preparation (P=0.

Influence of distinct anatomic subregions of the supraspinatus on humeral rotation.

The supraspinatus, having distinct anterior and posterior subregions, is most commonly considered an abductor of the humerus, but it has also been shown to induce humeral rotation. The objective of this study was to quantify the magnitude and direction of humeral rotation that results from loading the distinct anterior and posterior subregions of the supraspinatus. Fourteen cadaver specimens were tested under four loading conditions based on physiological cross section area of the supraspinatus: (1) anterior only; (2) posterior only; (3) physiologic (each subregion loaded simultaneously); and (4) nonphysiologic (the tendon loaded as a whole).
