BACKGROUND In the last several years, the lateral transpsoas approach to the thoracic and lumbar spine, also known as extreme lateral interbody fusion (XLIF) or direct lateral interbody fusion (DLIF), has become an increasingly common method to achieve fusion. Several recent large series describe several advantages to this approach, including less tissue(More)
This clinical practice guideline is based on a series of systematic reviews of published studies on the treatment of symptomatic osteoporotic spinal compression fractures. Of 11 recommendations, one is strong; one, moderate; three, weak; and six, inconclusive. The strong recommendation is against the use of vertebroplasty to treat the fractures; the(More)
STUDY DESIGN  Retrospective case series. OBJECTIVE  To assess fusion rates in patients with sacroiliac joint (SIJ) pain following a minimally invasive technique using fibular dowel allograft. METHODS  Thirty-seven consecutive patients (mean age: 42.5 years [range, 23-63 years]) with SIJ pain treated with 38 minimally invasive elective SIJ arthrodeses(More)
We hypothesised that trotters during an extended trot have lower energetic costs of locomotion (CT) than horses not bred for this behaviour. VO2 was measured as a function of speed in 7 Arabian horses (3 trained to extend their trotting speeds) and in 2 horses, of similar mass, bred to trot (Hackney). Both oxygen consumption and CT increased with speed and(More)
STUDY DESIGN  Randomized controlled animal trial. OBJECTIVES  To analyze the early and late phase effects of platelet-rich plasma (PRP) injection into and around the damaged intervertebral disc using an animal model, and to evaluate the needle puncture technique in creating a degenerative disc model. METHODS  The L4-L5 intervertebral disc of 18 adult(More)
REASON FOR PERFORMING STUDY It is well known that adding a load to a horse's back increases its energetic costs of locomotion, but the magnitude of increase obtained by loading the most distal portion of limb has not been measured. OBJECTIVES To measure oxygen consumption in horses with mass added to the back and hooves. Because such mass distribution(More)
that an electronic manifest is being used. Because § 172.204(d)(2) allows for a shipping paper to be ''signed manually, by typewriter, or by other mechanical means,'' no change to the HMR is needed when a paper copy of the electronic manifest is used as the shipping paper accompanying hazardous waste during transportation. The signature of the generator on(More)
STUDY DESIGN  Systematic review. STUDY RATIONALE  Some have noted several safety issues associated with the use of bone morphogenetic proteins (BMPs), including cancer risk, stating both BMP and their receptors had been isolated from human tumors. In addition, data presented to the US Food and Drug Administration (FDA) on the product AMPLIFY™ (rhBMP-2, 40(More)
OBJECT The purpose of this study was to evaluate the feasibility and safety of minimally invasive pedicle screw fixation combined with percutaneous vertebroplasty (PVP) for treating acute thoracolumbar osteoporotic vertebral compression fracture (VCF) and preventing secondary VCF after PVP. METHODS Twenty patients with a mean age of 73.6 years (range(More)
