Background: The slope of the tibial plateau has been proposed as a reason for failure of anterior cruciate ligament reconstruction.
Purpose: To evaluate the interobserver reliability of measurements of tibial slope on radiographs versus magnetic resonance imaging (MRI) scans and to assess whether the modalities can be used interchangeably for this purpose.
Study Design: Cohort study (diagnosis); Level of evidence, 3.
Wireless Smartphone ECG Enables Large-Scale Screening in Diverse Populations.
J Cardiovasc Electrophysiol
May 2015
Article Synopsis
- - The text discusses how internet-connected smartphones and tablets can improve ECG screening and diagnosis by enabling wireless, real-time monitoring, making it more efficient and accessible for users.
- - The study compared the accuracy of smartphone ECGs to standard 12-lead ECGs in different groups (healthy young adults, elite athletes, and cardiology patients) by analyzing 30-second lead I ECG waves from 381 participants.
- - Results showed that smartphone ECGs accurately identify key heart metrics with sensitivities ranging from 72% to 94% and high specificities above 94%, highlighting their effectiveness for diverse populations and potential for enhanced analysis through smartphone applications.
Case: We present two cases of anterior glenohumeral instability in which both the humeral head and the glenoid were reconstructed concurrently with use of allografts; we discuss the midterm outcomes at four and one-half and five years of follow-up, respectively.
Conclusion: In our experience, concomitant glenoid and humeral head allograft reconstruction for anterior glenohumeral instability with severe combined humeral head and glenoid pathology yielded good midterm clinical, functional, and radiographic outcomes. This treatment approach may be a viable option for young and active patients presenting with severe combined glenoid and humeral pathology and warrants additional investigation.
Background: Up to 1 billion people have insufficient or deficient vitamin D levels. Despite the well-documented, widespread prevalence of low vitamin D levels and the importance of vitamin D for athletes, there is a paucity of research investigating the prevalence of vitamin D deficiency in athletes.
Hypothesis: We investigated the prevalence of abnormal vitamin D levels in National Collegiate Athletic Association (NCAA) Division I college athletes at a single institution.
Background: Although operative treatment may offer an appropriate management option for displaced glenoid fractures, there is sparse research assessing post-operative functional outcomes. This study assessed functional outcomes of patients after undergoing open reduction and internal fixation of displaced glenoid fractures.
Methods: Fifteen patients were treated with open reduction and internal fixation for displaced intra-articular fractures between 2005 and 2010.
