Medical encounters (including injury and illness) at mass community-based endurance sports events: an international consensus statement on definitions and methods of data recording and reporting

Mass participation endurance sports events are popular but a large number of participants are older and may be at risk of medical complications during events. Medical encounters (defined fully in the statement) include those traditionally considered 'musculoskeletal' (eg, strains) and those due to 'illness' (eg, cardiac, respiratory, endocrine). The rate of sudden death during mass endurance events (running, cycling and triathlon) is between 0.4 and 3.3 per 100 000 entrants. The rate of other serious medical encounters (eg, exertional heat stroke, hyponatraemia) is rarely reported; in runners it can be up to 100 times higher than that of sudden death, that is, between 16 and 155 per 100 000 race entrants. This consensus statement has two goals. It (1) defines terms for injury and illness-related medical encounters, severity and timing of medical encounters, and diagnostic categories of medical encounters, and (2) describes the methods for recording data at mass participation endurance sports events and reporting results to authorities and for publication. This unifying consensus statement will allow data from various events to be compared and aggregated. This will inform athlete/patient management, and thus make endurance events safer

Randomized clinical trial of surgery versus conservative therapy for carpal tunnel syndrome [ISRCTN84286481]

BACKGROUND: Conservative treatment remains the standard of care for treating mild to moderate carpal tunnel syndrome despite a small number of well-controlled studies and limited objective evidence to support current treatment options. There is an increasing interest in the usefulness of wrist magnetic resonance imaging could play in predicting who will benefit for various treatments. METHOD AND DESIGN: Two hundred patients with mild to moderate symptoms will be recruited over 3 1/2 years from neurological surgery, primary care, electrodiagnostic clinics. We will exclude patients with clinical or electrodiagnostic evidence of denervation or thenar muscle atrophy. We will randomly assign patients to either a well-defined conservative care protocol or surgery. The conservative care treatment will include visits with a hand therapist, exercises, a self-care booklet, work modification/ activity restriction, B6 therapy, ultrasound and possible steroid injections. The surgical care would be left up to the surgeon (endoscopic vs. open) with usual and customary follow-up. All patients will receive a wrist MRI at baseline. Patients will be contacted at 3, 6, 9 and 12 months after randomization to complete the Carpal Tunnel Syndrome Assessment Questionnaire (CTSAQ). In addition, we will compare disability (activity and work days lost) and general well being as measured by the SF-36 version II. We will control for demographics and use psychological measures (SCL-90 somatization and depression scales) as well as EDS and MRI predictors of outcomes. DISCUSSION: We have designed a randomized controlled trial which will assess the effectiveness of surgery for patients with mild to moderate carpal tunnel syndrome. An important secondary goal is to study the ability of MRI to predict patient outcomes

Operative Experience During Orthopaedic Residency Compared with Early Practice in the U.S.

BACKGROUND: The goal of surgical education is to prepare the trainee for independent practice; however, the relevance of the current residency experience to practice remains uncertain. The purpose of this study was to identify the surgical procedures most frequently performed in orthopaedic residency and in early surgical practice and to identify surgical procedures performed more often or less often in orthopaedic residency compared with early surgical practice. METHODS: This retrospective cohort study included American Medical Association (AMA) Current Procedural Terminology (CPT) codes (n = 4,329,561 procedures) reported by all U.S. orthopaedic surgery residents completing residency between 2010 and 2012 (n = 1,978) and AMA CPT codes for all procedures (n = 413,370) reported by U.S. orthopaedic surgeons who took the American Board of Orthopaedic Surgery Part II certifying examination between 2013 and 2015 (n = 2,205). Relative rates were determined for AMA CPT codes and AMA CPT code categories for adult and pediatric surgeries that had frequencies of ≥0.1% for both practitioners and residents. RESULTS: The top 25 adult AMA CPT code categories contributed 82.1% of the total case volume for residents and 82.4% for practitioners. Knee and shoulder arthroscopy were the most frequently performed procedures in adults in both residency and early practice. Humerus/elbow fracture and/or dislocation procedures and other musculoskeletal-introduction or removal procedures were the most frequently performed procedures in pediatric cases in both residency and early practice. Of the total 78 adult and 82 pediatric code categories included in our analysis that had a frequency of \u3e1% in residency or early practice, there were 4 adult and 6 pediatric code categories demonstrating 44% to 1,164% greater frequency in residency than in early practice, and there were 8 adult and 7 pediatric code categories demonstrating 26% to 73% less frequency in residency than in early practice. CONCLUSIONS: Similarity between residency and early practice experience is generally strong. However, we identified several AMA CPT code categories and individual CPT codes for which the level of exposure during residency varied substantially from early practice experience. These findings can help residencies ensure adequate trainee exposure to procedures performed commonly in early practice

Estimation of return-to-sports-time for athletes with stress fracture – an approach combining risk level of fracture site with severity based on imaging

<p>Abstract</p> <p>Background</p> <p>The aim was to compare the return-to-sports-time (RTST) following stress fractures on the basis of site and severity of injury. This retrospective study was set up at a single institution. Diagnosis was confirmed by an interdisciplinary adjudication panel and images were rated in a blinded-read setting.</p> <p>Methods</p> <p>52 athletes (female, n = 30; male, n = 22; mean age, 22.8 years) with stress fracture (SFX) who had undergone at least one examination, either MRI or bone scintigraphy, were included. Magnetic resonance images (MRI) and/or bone scintigraphy (BS) of SFX were classified as either low- or high-grade SFX, according to existing grading systems. For MRI, high-grade SFX was defined as visibility of a fracture line or bone marrow edema in T1-, T2-weighted and short tau inversion recovery (STIR) sequences, with low-grade SFX showing no fracture line and bone marrow edema only in STIR and/or T2-weighted sequences. In BS images, a mild and poorly defined focal tracer uptake represented a low-grade lesion, whereas an intense and sharply marginated uptake marked a high-grade SFX. In addition, all injuries were categorized by location as high- or low-risk stress fractures. RTST was obtained from the clinical records. All patients were treated according to a non-weight-bearing treatment plan and comprehensive follow-up data was complete until full recovery. Two-sided Wilcoxon’s rank sum test was used for group comparisons.</p> <p>Results</p> <p>High-risk SFX had a mean RTST of 132 days (d) [IQR 64d – 132d] compared to 119d [IQR 50d – 110d] for low-risk sites (p = 0.19). RTST was significantly longer (p = 0.01) in high-grade lesions [mean, 143d; IQR 66d – 134d] than in low-grade [mean, 95d; IQR 42d – 94d]. Analysis of high-risk SFX showed no difference in RTST (p = 0.45) between high- and low-grade [mean, 131d; IQR 72d – 123d vs. mean, 135d; IQR 63d – 132d]. In contrast, the difference was significant for low-risk SFX (p = 0.005) [low-grade; mean, 61d; IQR 35d – 78d vs. high-grade; mean, 153d; IQR 64d – 164d].</p> <p>Conclusion</p> <p>For SFX at low-risk sites, the significant difference in RTST between low- and high-grade lesions allows more accurate estimation of RTST by this approach. Both location of the injury and severity determined by imaging should therefore be considered for prediction of RTST.</p
