Arthroscopic rotator cuff repair using a transosseous knotless anchor (ATOK).

Background: This article reviews the clinical and radiographic outcomes in a noninferiority trial use of a transosseous knotless anchor to perform arthroscopic rotator cuff repairs in a patient cohort that have an increased incidence of osteoporosis.

Methods: Patients aged over 60 with a documented rotator cuff tear and who failed a rehab program underwent repair using an arthroscopic transosseous knotless (ATOK) anchor. Patients were prospectively reviewed using shoulder functional assessments (age-adjusted Constant score, Oxford Shoulder Score, American Shoulder and Elbow Surgeons Standardized Shoulder Assessment Form [ASES], visual analog scale [VAS] pain scores), and underwent preoperative as well as 1-, 3-, and 12-month postoperative magnetic resonance imaging.

Isolation of osteocytes from human trabecular bone.

Osteocytes are essential regulators of bone homeostasis. However, they are difficult to study due to their location within the bone mineralised matrix. Although several techniques have been published for the isolation of osteocytes from mouse bone, no such technique has been described for human osteocytes.

Total shoulder arthroplasty using trabecular metal augments to address glenoid retroversion: the preliminary result of 10 patients with minimum 2-year follow-up.

Background: Options to address glenoid retroversion include eccentric reaming, bone grafting, modifications to component shape, and reverse shoulder arthroplasty. Trabecular metal (TM) augments have been used extensively in the hip and knee to address bone deficiency in arthroplasty as part of a hybrid combination of high-density polyethylene, polymethyl methacrylate, and TM. This study presents the initial results of the use of specifically designed augments in the shoulder to address glenoid retroversion as part of total shoulder arthroplasty (TSA).

Learning and Study Strategies Inventory subtests and factors as predictors of National Board of Chiropractic Examiners Part 1 examination performance.

Objective: This study was designed to extend research on the relationship between chiropractic students' learning and study strategies and national board examination performance.

Methods: Sixty-nine first trimester chiropractic students self-administered the Learning and Study Strategies Inventory (LASSI). Linear trends tests (for continuous variables) and Mantel-Haenszel trend tests (for categorical variables) were utilized to determine if the 10 LASSI subtests and 3 factors predicted low, medium and high levels of National Board of Chiropractic Examiners (NBCE) Part 1 scores.

Differences in learning and study strategies inventory scores between chiropractic students with lower and higher grade point averages.

Purpose: This pilot study was designed to investigate the relationship between chiropractic students' learning and study strategies and academic performance. Differences in strategic learning between chiropractic students with higher grade points averages (GPAs) and those with lower GPAs have not been previously reported.

Methods: Fifty-seven consenting first-trimester chiropractic students self-administered the Learning and Study Strategies Inventory (LASSI).
