Accuracy of Ultrasound Compared to Magnetic Resonance Imaging in the Diagnosis of Thumb Ulnar Collateral Ligament Injuries: A Prospective Case Series.

This prospective case series compared the accuracy of ultrasound (US) to magnetic resonance imaging (MRI) in differentiating complete displaced (CD) thumb ulnar collateral ligament (UCL) tears from nondisplaced injuries in 10 patients with suspected traumatic thumb UCL injuries. Ultrasound identified 100% (2 of 2) of MRI-documented CD tears, both of which were further confirmed during surgical repair. Ultrasound identified the absence of CD tears in the remaining 8 patients.

Intraarticular platelet-rich plasma injection in the treatment of knee osteoarthritis: review and recommendations.

Intraarticular platelet-rich plasma (PRP) injection has emerged as a promising treatment for knee osteoarthritis. Studies to date, including multiple randomized controlled trials, have shown that PRP is a safe and effective treatment option for knee osteoarthritis. Intraarticular PRP is similar in efficacy to hyaluronic acid, and seems to be more effective than hyaluronic acid in younger, active patients with low-grade osteoarthritis.

Golf after total knee arthroplasty: do patients return to walking the course?

Background: Golf provides an opportunity for relatively low-impact exercise for nearly all age groups and is considered a recommended activity for patients after total knee arthroplasty.

Hypothesis: We hypothesized that total knee arthroplasty would afford patients increased ability to participate in and enjoy golf, allowing a large percentage of these patients to walk the golf course.

Study Design: Case series; Level of evidence, 4.

Ultrasound-guided piriformis injection: technique description and verification.

Piriformis injections are commonly used in the evaluation and treatment of patients presenting with buttock pain syndromes. Because of its small size, deep location, and relation to adjacent neurovascular structures, the piriformis is traditionally injected by using electromyographic, fluoroscopic, computed tomographic, or magnetic resonance imaging guidance. This report describes and verifies a technique for performing ultrasound-guided piriformis injections.
