BACKGROUND During arthroscopic Bankart repair, inferior anchor placement is critical to a successful outcome. Low anterior anchors may be placed with a standard straight guide via midglenoid portal, with a straight guide with trans-subscapularis placement, or with curved guide systems. Purpose/ HYPOTHESIS To evaluate glenoid suture anchor trajectory, position, and biomechanical performance as...

Is membrane fusion an essentially passive or an active process? It could be that fusion proteins simply need to pin two bilayers together long enough, and the bilayers could do the rest spontaneously. Or, it could be that the fusion proteins play an active role after pinning two bilayers, exerting force in the bilayer in one or another way to direct the fusion process. To distinguish these alte...

PURPOSE To compare the results of arthroscopic Bankart repair completed with knot-tying with results of the procedure performed with knotless suture anchors. METHODS We evaluated 82 patients who underwent arthroscopic Bankart repair. A total of 61 patients were treated with knot-tying suture anchors, and 21 patients were treated with knotless suture anchors during the same period. In all, 75 ...

Posterior shoulder instability, although relatively rare in the general population, is more commonly seen in athletes, especially those in contact sports. Although nonoperative treatment has been associated with satisfactory results in the setting of posterior shoulder instability, conservative management may ultimately fail and lead to recurrence particularly in young, male patients. Both arth...

This technical report focus on the definition of anchors and links for nested composite nodes, that is, composite nodes containing other composite nodes. It considers questions such as link inheritance and node reference, which become fairly complex in the presence of nested composite nodes. Then, the paper extends the discussion to include virtual anchors and links, defined by expressions in a...

Phenotypic variation results from the balance between sources of variation and counteracting regulatory mechanisms. Canalization and developmental stability are two such mechanisms, acting at two different levels of regulation. The issue of whether or not they act concurrently as a common developmental buffering capacity has been subject to debate. We used geometric morphometrics to quantify th...

introduction: several factors affect the academic performance of college students and parenting style is one significant factor. the current study has been done with the purpose of investigating the relationship between parenting styles, academic achievement and career path of students at shiraz university of medical sciences. methods: this is a correlation study carried out at shiraz universit...

Pull out tests for bone anchors used in surgical robotics were performed to prove the strength of the bone anchor -bone combination. Forces and displacement were measured to evaluate the suitability of the bone anchors as a connection between a surgical robot and bone. A universal experimental setup was designed to conduct the pull out tests. As specimens, human cranial cadaver bone, porcine ca...

BACKGROUND Surgeons can control not only the angle but also the depth of suture anchor placement during arthroscopic rotator cuff repair, although the tendency may be to place suture anchors on the deep side to avoid damage from prominent anchor eyelets. However, little information is available regarding possible effects of suture anchor depth on construct failure mechanisms. HYPOTHESIS Ancho...

Using Conservation of Resources theory (COR) as our conceptual framework we investigate the relationship between entrepreneurial career anchor (ECA) and self-cultivation (SC) values Chinese business students. We additionally examine moderating role in-group collectivist (IGVs) interaction IGVs gender in this relationship. Based on survey data from 643 undergraduate students attending a universi...
