Radiographic evaluation provides essential information regarding the diagnosis and treatment of musculoskeletal disorders. We evaluated ability hip specialists to reliably identify important radiographic features make a based on plain radiographs alone. Five one fellow performed blinded review 25 control hips, hips with developmental dysplasia (DDH), 27 femoroacetabular impingement (FAI). On two separate occasions, readers assessed acetabular version, inclination depth, position femoral head...

Newly revised in the light of renewed debate last five years, this second edition Patrick Morgan's book is a comprehensive review logic and practice deterrence. Morgan highlights difficulties involved immediate deterrence, use threat to deter specific, situation. He then explores irrationality strategic options that general nuclear deterrence offers. shows how differences theories decisions are made alter views works -- an opponent will respond threat. Finally, he considers way reducing our...

Background: The orthopaedic literature contains relatively little quantitative information regarding the anatomy of posterior aspect knee. purpose present study was to provide a detailed description of, and propose standard nomenclature for, Methods: Detailed dissection twenty nonpaired, fresh-frozen knees performed. Posterior knee structures were measured according length, width, and/or distance reproducible osseous landmarks. Results: semimembranosus tendon had eight attachments distal...

Prophylactic antibiotics are frequently withheld until cultures obtained in revision total knee arthroplasty (TKA). We undertook a prospective study to determine whether prophylactic preoperative intravenous would affect the results of intraoperatively. enrolled 25 patients with 26 infected TKAs, known infecting organism, and no recent antibiotic therapy. Reaspiration TKA was performed after anesthesia sterile preparation. Intravenous prophylaxis then administered tourniquet inflated....

Background: The accurate preoperative diagnosis of infection is an essential component decision-making prior to revision total knee arthroplasty. When modalities used detect reveal equivocal findings, the surgeon may rely on intraoperative testing. While Gram stains are routinely performed during arthroplasty, their value remains unclear. Methods: We retrospectively reviewed records 945 arthroplasties at three university institutions which patients were referred for joint arthroplasty;...

Background Ligament restraints to terminal knee extension are poorly understood. Hypotheses (1) As with other motions of the knee, genu recurvatum is limited primarily by a named, identifiable structure. (2) largest static structure posterior oblique popliteal ligament uniquely suited act as checkrein hyperextension. Study Design Descriptive laboratory study. Methods Twenty fresh-frozen human knees were divided into 3 groups for sectioning Extension moments 14 and 27 N·m applied before after...

In comparison with the Cold War era, deterrence in international politics has changed significantly, even though many of basic components that still exist and continue to have an impact. Deterrence is now less salient national security policies management, more recessed, particularly nuclear deterrence. This primarily due huge changes ushered by end War, great-power political relationships, which are continuing unfold. Important developments underway respect deterrence, extended collective...

To evaluate the ability of T2* mapping to help differentiate damaged from normal acetabular cartilage in patients with femoroacetabular impingement (FAI).The institutional review board approved this retrospective study, and requirement obtain informed consent was waived. The study complied HIPAA guidelines. authors reviewed relaxation time maps 28 hips 26 consecutive (mean patient age, 28.2 years; range, 12-53 eight male (nine hips) a mean age 26.7 years [range, 16-53 years]; 18 female (19...

The objective of this study was to demonstrate the feasibility simultaneous bilateral hip imaging at 7 Tesla. Hip joint MRI becomes clinically critical since recent advances have made arthroscopy an efficacious approach treat a variety early diseases. success these treatments requires reliable and accurate diagnosis intraarticular abnormalities stage. Articular cartilage assessment is especially important guide surgical decisions but difficult achieve with current MR methods. Because gains...

While the problem of war in general deserves continuing scholarly attention, it seems appropriate to single out systemwide—that is, global—war for intensive analysis as kind that poses gravest threat catastrophe. Such a can best be understood an integral part long cycle, recurring pattern development and operation global layer international system. From this perspective design solution requires either disruption cycle or functional substitute leadership selection process these wars have...

Symptomatic sacroiliac (SI) joint disease is poorly understood. The literature provides no clear aetiology for SI pathology, making evaluation and diagnosis challenging. We hypothesised that patients with documented pain might provide insight into the of these symptoms. Specifically, we questioned whether symptoms be associated abnormal hip radiographs. reviewed pelvic radiographs a prospectively collected cohort 30 consecutive pathology. This database included 33 hips from patients....

A study was conducted to determine the prevalence of Brucella canis antibodies in specified groups based on their exposure dogs. The method used a microtiter technique, and presence at 1:12 or greater dilution serum considered positive test. Eleven (5.7%) newborn infants had evidence maternal antibodies, 67.8% persons with an average dogs B. 62.1% males 72.4% females (P less than equal 0.001). Veterinarians much higher rate infection (72.6%) male blood donors (56.9%) 0.01). Patients fevers...
