Reliability of new radiographic measurement techniques for elbow bony impingement.

Background: Identifying the location and scale of radiographic changes in elbow bony impingement (EBI) is critical in formulating an appropriate diagnosis and treatment plan for such patients. The purpose of present study was to evaluate the intra-rater and inter-rater reliability of the new radiographic parameters, Anterior Impingement angle (AIa) and Posterior Impingement angle (PIa), for EBI. In addition, to determine if there was a relationship between radiographic parameters and clinical evaluation.

MRI Findings of Early Osteoarthritis in Patients Who Sustained Septic Arthritis of the Knee After ACL Reconstruction.

Background: Although a rare complication, septic arthritis (SA) after anterior cruciate ligament (ACL) reconstruction has potentially devastating consequences for the knee joint.

Purpose: To prospectively analyze, at a mean 4-year follow-up, subjective, clinical, radiographic, and magnetic resonance imaging (MRI) findings between patients with SA and those with no septic complication after ACL reconstruction.

Study Design: Cohort study; Level of evidence, 2.

Evaluation of clinical tests for partial distal biceps tendon ruptures and tendinitis.

Background: The clinical diagnosis of partial distal biceps tendon ruptures or tendinosis can be challenging. Three clinical tests have been described to aid in an accurate and timely diagnosis: biceps provocation test, tilt sign, and resisted hook test. However, not much is known about the sensitivity, specificity, and inter-rater reliability as the available evaluations are based on small groups or are case based.

Role of the interosseous membrane in post-traumatic forearm instability: instructional review.

Purpose: In the last two decades, a strong interest on the interosseous membrane (IOM) has developed.

Methods: The authors present a review of the new concepts regarding the understanding of forearm physiology and pathology, with current trends in the surgical management of these rare and debilitating injuries.

Results: Anatomical and biomechanical studies have clarified the anatomy of forearm constrains and their role in forearm longitudinal and transverse stability.

Feasibility of transcutaneous electrical muscle stimulation in acute exacerbation of COPD.

Transcutaneous electrical muscle stimulation is a well-established intervention for rehabilitation of clinically stable patients with chronic obstructive pulmonary disease. This study investigated feasibility and safety of this method during acute exacerbation of chronic obstructive pulmonary disease. We included 19 patients (71 ± 6 years, 76% men) who underwent two sessions/day during hospitalization (15 ± 1 training sessions).
