Volar and Dorsal Blood Supply to the Lunate: A Cadaveric Study.

Although various studies have proposed vascular and mechanical factors, the etiology of Kienböck disease is unknown. Kienböck theorized that lunatomalacia resulted from traumatic disruption of blood supply and bony nutrition to the lunate. Extraosseous supply to the lunate, as far as volar or dorsal vessels are concerned, is still controversial.

The purpose of this study was to examine the relationship between smoking and back pain in a cross-sectional analysis. Using the Osteoarthritis Initiative database, a multi-center, longitudinal, observational cohort study with 4796 participants, we examined the prevalence of back pain and of limitations in activity due to back pain, as well as the frequency and severity of back pain in participants who were current smokers compared to those who had never smoked. Data was evaluated using binary and ordinal logistic regression analyses.

The Effect of Diabetes Mellitus on Revision Discectomy after Single-level Lumbar Discectomy.

Diabetes currently affects over 25 million Americans, with the elderly carrying much of the disease burden. It's well known that diabetes increases the risk of surgical complications, but few studies have analyzed its effects on reoperation rates after single-level lumbar discectomy. Data was obtained using the commercially available Explorys software, which houses de-identified data for several healthcare systems.

Effect of Nicotine Dependence and Smoking on Revision Diskectomy After Single-Level Lumbar Diskectomy.

Removal of a herniated disk that is causing neural compression is among the most common indications for spinal surgery. Previous population database studies of risk factors for reoperation after this procedure analyzed small to medium numbers of patients. To date, no study has concurrently assessed the effect of modifiable risk factors, such as smoking and nicotine dependence, with a large number of patients.

The Effect of Obesity on Revision Discectomy After Singlelevel Lumbar Discectomy.

The prevalence of obesity has been rising, creating a major public health concern. While several studies have shown obesity to increase the risk of surgical complications, few have analyzed its effects on reoperation, specifically after singlelevel lumbar discectomy. Data was obtained using the commercially available Explorys software that houses deidentified data for several major healthcare systems.

Shorter Time to Surgery Is Associated With Better Outcomes for Spondylolisthesis in the Workers' Compensation Population.

This study sought to determine the impact of time to surgery on clinical outcomes in patients with spondylolisthesis in the workers' compensation (WC) population. There is conflicting evidence regarding the effect of time to surgery on patients with spondylolisthesis. Patients receiving WC are known to have worse outcomes following spine surgery compared with the general population.

The clinical effects of school sandplay group therapy on general children with a focus on Korea Child & Youth Personality Test.

Background: This study intended to examine the comprehensive clinical effects of school sandplay group counseling on the emotions and behaviors of children for the first time in Korea.

Methods: To this objective, 10 sessions of in-school sandplay group counseling were administered to 113 fourth- to sixth-graders in an elementary school located in Cheonan city for 12 weeks from March to July 2015. Each small group consisted of 10 to 16 children and the entire 12 sessions were composed of a baseline test, 10 therapy sessions, and a post-test and evaluation session.

Multilevel Lumbar Fusion Is a Risk Factor for Lower Return to Work Rates Among Workers' Compensation Subjects With Degenerative Disc Disease.

The Effect of Age on the Benefits of Early Decompression for Cervical Spondylotic Myelopathy.

Cervical myelopathy is the most common cause of acquired spinal cord dysfunction in people aged >55 years. Advanced age and duration of symptoms have been implicated in the literature as negative prognostic indicators for postoperative functional improvement, but very few studies have evaluated the interaction of these factors. We retrospectively reviewed 125 patients who underwent surgery for cervical myelopathy.
