    Abstract: The majority of rim recession for femoroacetabular impingement (FAI) is performed anteriorly and has traditionally been assessed by the lateral center-edge (CE) angle, which correlates most closely with lateral coverage. The radiographic false-profile view permits measurement of anterior coverage via the anterior CE angle and more closely correlates with anterior coverage. Purpose: To answer the following questions: (1) How does incremental anterior rim recession change lateral and anterior CE angles? and (2) Can these changes be predicted by a formula? Study Design: Descriptive laboratory study. Methods: Twelve cadaveric hips were dissected free of soft tissue to expose the anterior acetabular rim. Incremental resections of 2.5 mm (range, 0-10 mm) were performed from the 12- to 3-o’clock position using a Dremel rotary tool. Anteroposterior hip and false-profile radiographs were obtained at each interval using a fluoroscopic C-arm. The lateral and anterior CE angles were measured by 3 orthopaedic surgeons. Results: The average preresection lateral CE angle was 35.1°, and the mean decrease in lateral CE angle from 0 to 10 mm was 9.9°; the average preresection anterior CE angle was 38.4° and the mean decrease in anterior CE angle from 0 to 10 mm was 18.2°. The anterior CE angle decreased by a factor of 1.9 when compared with the lateral CE angle ( P = 2 × 10 −7 ). The lateral CE angle decreased by approximately 1° (1.0°) per millimeter of rim recessed. The anterior CE angle decreased by approximately 2° (1.8°) per millimeter of rim recessed. Conclusion: The lateral CE angle should not be extrapolated to reflect anterior acetabular coverage. The anterior CE angle is a superior marker and predictably decreases with rim recession at double the rate of the lateral CE angle. Clinical Relevance: The false-profile view is recommended in the perioperative workup for all patients undergoing arthroscopic treatment of pincer impingement.

    Wearable Performance Devices in Sports Medicine

    Abstract: Wearable performance devices and sensors are becoming more readily available to the general population and athletic teams. Advances in technology have allowed individual endurance athletes, sports teams, and physicians to monitor functional movements, workloads, and biometric markers to maximize performance and minimize injury. Movement sensors include pedometers, accelerometers/gyroscopes, and global positioning satellite (GPS) devices. Physiologic sensors include heart rate monitors, sleep monitors, temperature sensors, and integrated sensors. The purpose of this review is to familiarize health care professionals and team physicians with the various available types of wearable sensors, discuss their current utilization, and present future applications in sports medicine. Evidence Acquisition: Data were obtained from peer-reviewed literature through a search of the PubMed database. Included studies searched development, outcomes, and validation of wearable performance devices such as GPS, accelerometers, and physiologic monitors in sports. Study Design: Clinical review. Level of Evidence: Level 4. Results: Wearable sensors provide a method of monitoring real-time physiologic and movement parameters during training and competitive sports. These parameters can be used to detect position-specific patterns in movement, design more efficient sports-specific training programs for performance optimization, and screen for potential causes of injury. More recent advances in movement sensors have improved accuracy in detecting high-acceleration movements during competitive sports. Conclusion: Wearable devices are valuable instruments for the improvement of sports performance. Evidence for use of these devices in professional sports is still limited. Future developments are needed to establish training protocols using data from wearable devices.

    Following Incarceration, Most Released Offenders Never Return to Prison

    Abstract: Recent studies suggest that 50% of offenders released from state prisons return to prison within 3 to 5 years. In contrast, this article shows that roughly two of every three offenders who enter and exit prison will never return to prison. Using data from the Bureau of Justice Statistics’ newly revised National Corrections Reporting Program, we examine prison admissions and releases over a 13-year period in 17 states and over shorter periods in other states to determine the rate at which individual offenders return to prison. We distinguish between the traditional event-based sampling methods for studying recidivism and our alternative offender-based method, explaining how each is useful but how the two approaches answer different policy questions.

    Religiosity is Associated with Affective Status in Symptomatic HIV-infected African-American Women

    Abstract: This study examined the relationship between religiosity and the affective and immune status of 33 HIV-seropositive mildly symptomatic African-American women (CDC stage B) in a replication of a prior study that reported an association between religiosity and affective and immune status in HIV-seropositive gay men. All women completed an intake interview, a set of psychosocial questionnaires, and provided a venous blood sample. Consistent with prior work, factor analysis of 12 religious-oriented response items revealed two distinct aspects to religiosity: religious coping and religious behavior. Religious coping (e.g. placing trust in God, seeking comfort in religion) was significantly associated with lower depression and anxiety. Regression analyses revealed the association between religious coping and depressive symptoms appears to be mediated by an active coping style. However, the association between religious coping and anxiety does not appear to be mediated by either active coping or sense of self-efficacy in these women. In contrast to prior work, neither religious coping nor religious behavior was significantly associated with immune status as measured by T helper-inducer (CD41) cell counts.

    Abstract: Falls present a large danger to the geriatric population, with one in three individuals over the age of 65 experiencing at least one fall annually. With most falls occurring while walking, the relationship between inclined walking and fall risk has not been fully explored. In this study, 16 healthy young participants (age: 26.8 ±5.4 years, height: 175.0±11.0 cm, weight: 68.2 ±19.9 kg) walked on a treadmill with level surface and 10 degrees incline/decline in a virtual environment laboratory. We found that gait parameters and lower extremity joint moments were affected by surface inclination. These observed changes in joint moments and gait parameters may present challenges to the older population especially with musculoskeletal disorders and thereby increase the risk of falls. This study offers new information on the effects of incline and decline surface walking compared to normal flat ground surface walking.
