Psychological Distress Is Associated with Greater Perceived Disability and Pain in Patients Presenting to a Shoulder Clinic.
Shoulder disorders are a common cause of disability and pain. The Shoulder Pain and Disability Index (SPADI) is a frequently employed and previously validated measure of shoulder pain and disability. Although the SPADI has high reliability and construct validity, greater differences between individual patients are often observed than would be expected on the basis of diagnosis and pathophysiology alone. This study aims to determine how psychological factors (namely depression, catastrophic thinking, and self-efficacy) affect pain and perceived disability in the shoulder. ⋯ Catastrophic thinking and decreased self-efficacy are associated with greater shoulder pain and disability. Our data support the notion that patient-to-patient variation in symptom intensity and magnitude of disability is more strongly related to psychological distress than to the specific shoulder diagnosis.

Acetabular Anteversion Changes Due to Spinal Deformity Correction: Bridging the Gap Between Hip and Spine Surgeons.
Hip osteoarthritis often coexists with adult spinal deformity, an abnormality in which sagittal spinopelvic malalignment is present. Debate exists whether to perform spinal realignment correction or total hip arthroplasty first. Hip extension and pelvic tilt are important compensatory mechanisms in the setting of sagittal spinopelvic malalignment and change after spinal realignment. We performed this study to evaluate the effect that the spinal realignment surgical procedure has on acetabular anteversion. ⋯ Patients with spinopelvic malalignment had a high prevalence of excessively anteverted acetabular components. Sagittal spinal correction following total hip arthroplasty resulted in reduced acetabular anteversion, which may have implications for stability. Changes in anteversion are most closely related to changes in pelvic tilt in an almost one-to-one ratio.

Competency-Based Medical Education: Can Both Junior Residents and Senior Residents Achieve Competence After a Sports Medicine Training Module?
Competency-based medical education as a resident-training format will move postgraduate training away from time-based training, to a model based on observable outcomes. The purpose of this study was to determine whether junior residents and senior residents could demonstrate clinical skills to a similar level, after a sports medicine rotation. ⋯ Despite intensive teaching within a competency-based medical education model, junior residents were not able to demonstrate knowledge as well as senior residents, suggesting that overall clinical experience is critically important for achieving competency as measured by the Objective Structured Clinical Examination.

Management of Modifiable Risk Factors Prior to Primary Hip and Knee Arthroplasty: A Readmission Risk Assessment Tool.
Preoperative risk stratification and optimization of preoperative care may be helpful in reducing readmission rates after primary total joint arthroplasty. Assessment of the predictive value of individual modifiable risk factors without a tool to assess cumulative risk may not provide proper risk stratification of patients with regard to potential readmissions. As part of a Perioperative Orthopaedic Surgical Home model, we developed a scoring system, the Readmission Risk Assessment Tool (RRAT), which allows for risk stratification in patients undergoing elective primary total joint arthroplasty at our institution. The purpose of this study was to analyze the relationship between the RRAT score and readmission after primary hip or knee arthroplasty. ⋯ Population health management, cost-effective care, and optimization of outcomes to maximize value are the new maxims for health-care delivery in the United States. We found that the RRAT score had a significant association with readmission after joint arthroplasty and could potentially be a clinically useful tool for risk mitigation.

Randomized Controlled TrialEffect of Head Position on Intraocular Pressure During Lumbar Spine Fusion: A Randomized, Prospective Study.
Ischemic optic neuropathy resulting in visual loss is a rare but devastating complication of spine surgery. Elevated intraocular pressure (IOP) results in decreased perfusion and possibly ischemic optic neuropathy. We performed a randomized, prospective trial to evaluate the effect of head positioning on IOP during lumbar spine fusion. ⋯ Head elevation for adult lumbar spine fusion performed with the patient prone resulted in significantly lower IOP measurements than those seen when the operation was done with the patient's head in neutral. As lower IOP correlates with increased optic nerve perfusion, this intervention could mitigate the risk of perioperative blindness after spine surgery done with the patient prone.
