Background. Discal cyst has been identified as a rare cause of low back pain and radiating leg pain. The pathogenesis and management of this condition are still debated. The largest number of reported cases had undergone microsurgery while very few cases have been treated with percutaneous endoscopic discectomy (PED). Methods. An 18-year-old boy complained of low back pain radiating to right leg after a minor road traffic accident. Diagnosis of a discal cyst at L4-L5 level was made based on magnetic resonance imaging (MRI)...

BACKGROUND AND PURPOSE: Sacroiliac joint dysfunction (SIJD) is a condition affecting 15-30% of patients with low back pain seen in outpatient clinics. Currently there is no well-defined standard of care. The purpose of this case report is to discuss the multidisciplinary management between an athletic trainer and an optometrist for an athlete with bilateral SIJ dysfunction and a visual midline shift syndrome. CASE DESCRIPTION: A 21-year-old collegiate baseball player reported to the athletic training room, presenting with low back pain of three day duration, with tenderness over both posterior superior iliac spines (PSIS) (left > right)...

PURPOSE: The purpose of this study was to assess athletic activities associated with spondylolysis in children and adolescents in a New York metropolitan tertiary referral center. METHODS: We retrospectively evaluated 137 consecutive cases of symptomatic spondylolysis presenting to one of two pediatric orthopedic spine surgeons. Ten patients who did not participate in any organized athletics were excluded, leaving 127 children for analysis. Data regarding spondylolysis and athletic participation were gathered for analysis...

A professional baseball player presented to the orthopaedic clinic for a preseason assessment because of continued lumbar spine and flank pain. He had a laparoscopic appendectomy for a perforated appendix 8 months before his presentation. He was able to finish the previous season with only mild limitation. He presented with back pain that limited his activity. His examination was nonlocalizing, but subsequent computed tomography revealed a hepatic abscess. The abscess was drained; he was treated with intravenous antibiotics; and his symptoms resolved...

PURPOSE: We examined the associations between participation in different sports and exercise activities and neck, shoulder, and low back pains in adolescents. METHODS: This population-based study included the members of the Northern Finland Birth Cohort 1986, who, at the age of 15 to 16 yr, completed a questionnaire including items about their musculoskeletal pains and participation in various sport and exercise activities (N = 6945). Logistic regression analysis was used to evaluate how musculoskeletal pains are associated a) with participation in a certain type of sport or exercise activity and b) with the clusters formed by latent class analysis (LCA) according to the adolescents' profiles of participation in different sport and exercise activities...

BACKGROUND: Several studies have reported that physical loading related to competitive sports activities is associated with lumbar intervertebral disk degeneration. However, the association between types of sports activities and disk degeneration has not been clarified. HYPOTHESIS: The frequencies of disk degeneration may vary with the competitive sport because of the different postures and actions specific to each sport. STUDY DESIGN: Cross-sectional study (prevalence); Level of evidence, 3...

In this study, the relationship between the physical fitness of college baseball players found from 6 field tests and a performance evaluation by coaches was investigated. The purpose was to ascertain whether the results would be similar to those obtained in a previous study. The subjects of the study were 43 college baseball players (mean age, 20.7 +/- 1.4 years; mean athletic career, 10.9 +/- 2.6 years). Referring to the previous study, the field tests of physical fitness were composed of 6 items: throwing distance, back strength, medicine ball throwing, standing long jump, T-test, and base running...

Pars defect (spondylolysis) of the lumbar spine can cause chronic low back pain, and it sometimes requires surgical intervention. Direct repair is selected for the surgery if young adult patients do not present significant disc degeneration and lumbar instability. In order to lessen damages of back muscles during surgery, we added the use of a spinal endoscope to the "Buck's screwing procedure" the direct repair. There are four steps in this procedure: 1) identification of the defect, 2) curettage (refresh) of the defect, 3) percutaneous insertion of the annulated screws and 4) cancellous bone grafting...

OBJECTIVE: To review 16 years of National Collegiate Athletic Association (NCAA) injury surveillance data for women's softball and to identify potential areas for injury prevention initiatives. BACKGROUND: The NCAA Injury Surveillance System has tracked injuries in all divisions of NCAA softball from the 1988-1989 to the 2003-2004 seasons. This report describes what was found and why the findings are important for the safety, enhancement, and continued growth of the sport...

Lumbar zygapophyseal joints have long been considered a source of low back pain with or without leg pain. The objective of this prospective study was to investigate the therapeutic effectiveness of lumbar zygapophyseal joint radiofrequency denervation (RFD) followed by physical therapy, for the treatment of refractory lumbar zygapophyseal joint mediated low back pain secondary to lumbar zygapophyseal joint synovitis, in baseball pitchers. Participants included twelve male baseball pitchers with a diagnosis of lumbar zygapophyseal joint synovitis mediated low back pain and a subsequent difficulty in pitching...

Gunshots produce bruise patterns on persons who wear soft body armor when shot even though the armor stops the bullets. An adaptive fuzzy system modeled these bruise patterns based on the depth and width of the deformed armor given a projectile's mass and momentum. The fuzzy system used rules with sinc-shaped if-part fuzzy sets and was robust against random rule pruning: Median and mean test errors remained low even after removing up to one fifth of the rules. Handguns shot different caliber bullets at armor that had a 10%-ordnance gelatin backing...

Over the last few years, the recognised cardiovascular risks of sporting activities have been extended to include cardiac arrest resulting from low-energy precordial chest impact produced by projectiles (e.g. baseball) or bodily contact, in the young, healthy and active athlete [also known as commotio cordis (CC)]. However, case reports of CC in European medical literature can be traced back for at least 130 years. CC accounts for a small, but important, subset of sudden death during sporting activities. It is a devastating electrophysiological event in the young athlete, and one which has generated considerable concern, both in the medical profession as well as in the public...

The muscle firing pattern in 12 muscles throughout the lower extremity, trunk, and upper extremity during the batting swing is described in this study. The two hamstring muscles studied and the gluteal muscle had a similar pattern of high muscle activity during pre-swing and early swing, and then rapidly diminished. The vastus medialis demonstrated peak activity between 95 and 110% maximum muscle test (MMT) throughout the swing phases and follow-through. The erector spinae demonstrated activity from 85 to 185% MMT during the swing phases...

The associations between participation in several specific sports, use of free weights, and use of weight lifting equipment and herniated lumbar or cervical intervertebral discs were examined in a case-control epidemiologic study. Specific sports considered were baseball or softball, golf, bowling, swimming, diving, jogging, aerobics, and racquet sports. Included in the final analysis were 287 patients with lumbar disc herniation and 63 patients with cervical disc herniation, each matched by sex, source of care, and decade of age to 1 control who was free of disc herniation and other conditions of the back or neck...
