Mechanically Induced Periprosthetic Osteolysis: A Systematic Review.

Background: Peri-prosthetic bone loss can result from chemical, biological, and mechanical factors. Mechanical stimulation via fluid pressure and flow at the bone-implant interface may be a significant cause. Evidence supporting mechanically induced osteolysis continues to grow, but there is no synthesis of published clinical and basic science data.

Pediatric Septic Arthritis and Osteomyelitis in the USA: A National KID Database Analysis.

Background: Prior reports suggest that osteoarticular infections may be increasing over time.

Questions/purposes: We sought to determine if incidence rates, median in-hospital costs, and length of stay (LOS) of osteomyelitis, septic arthritis (SA), and combined infections have changed over time for pediatric patients, and how they compare to previously reported rates.

Methods: The Kids' Inpatient Database (KID), a US national sample of pediatric hospital discharge records from 1997, 2000, 2003, 2006, 2009, and 2012, was used to determine yearly estimated counts of infections in children 20 years of age or younger.

The Diagnostic Accuracy of Radiographs and Magnetic Resonance Imaging in Predicting Deltoid Ligament Ruptures in Ankle Fractures.

Background: Operative indications for supination-external rotation (SER) ankle fractures depend on the integrity of the medial structures. Despite the importance of assessing deep deltoid ligament injuries, the accuracy of common diagnostic tests has not been established.

Questions/purposes: The objective of this study was to compare the ability of injury (non-stress) and stress radiographs and magnetic resonance imaging (MRI) to diagnose deep deltoid ligament ruptures in operative SER ankle fractures.

An Epidemiologic Perspective on Scaphoid Fracture Treatment and Frequency of Nonunion Surgery in the USA.

Background: Scaphoid fractures treated non-operatively and operatively may be complicated by nonunion.

Questions/purposes: We sought to test the primary hypothesis that the incidence density of scaphoid fracture treatment is higher than previously estimated, to determine the frequency and risk factors for nonunion treatment, and to determine whether the frequency of surgical treatment increased over time.

Methods: The MarketScan database was queried for all records of treatment (casting and surgery) for closed scaphoid fractures over a 6-year period.

Firefighters Have a Higher Incidence of Trochlear Chondral Lesions than the Normal Population.

Background: Firefighters' knees are subjected to significant dynamic and static forces, resulting in increased knee complaints and a higher relative risk of osteoarthrosis, compared with aged-matched office workers. Firefighters wear or carry a total of 80 to 100 lbs. of gear while performing intensive physical activity.

: a home for all rheumatology research within the BMC Series.

This editorial accompanies the launch of , a new open access, peer-reviewed journal within the BMC Series portfolio, which considers studies on all aspects of rheumatological diseases. The Journal will also place a special emphasis on manuscripts reporting systemic and inflammatory conditions and connective tissue diseases, along with related comorbidities, including cardiovascular disease, malignancy and infection. Through the publication of a variety of article types, including Research articles, Case reports, Study protocols and Debates, will provide the rheumatology community with an open access avenue to disseminate research into rheumatological diseases, with the ultimate aim of improving patient care.

Vulvodynia and Concomitant Femoro-Acetabular Impingement: Long-Term Follow-up After Hip Arthroscopy.

Objective: We hypothesized that in patients with vulvodynia and femoro-acetabular impingement (FAI), vulvar pain may be generated by the effect of FAI on pelvic floor structures, and treatment with arthroscopy may improve vulvodynia. We also sought to identify characteristics of patients whose vulvodynia improved after arthroscopy.

Materials And Methods: A case series of patients with vulvodynia and FAI underwent physical therapy, and, if hip symptoms did not improve, arthroscopy.
