REVIEW
Charles Qin, Robert G Dekker, Mia M Helfrich, Anish R Kadakia
Interest in outpatient orthopedic surgery has been fueled by provider desire to control costs and development of rapid recovery protocols. Open reduction and internal fixation (ORIF) is a commonly elected treatment strategy for ankle fracture that may be performed in an outpatient setting. Lessons on cost-savings of the outpatient model in orthopedics can be learned in total joint replacement and spine surgery. Moreover, in properly selected patients, outpatient ORIF has been shown to be comparably safe. Reasons for admission of the surgically managed patient with ankle fractures, including concern for surgical delay and additional social factors, warrant further investigation...

Instabilities of the cervical spine after complete or incomplete corpectomy may be the result from resection due to stenosis induced myelopathy, tumors, infections or fractures. In this article, we report a 49-year-old female patient after surgical decompression and stabilization at C5/7 with permanent cervicobrachialgia due to cervical stenosis at C5/7. Corpectomy of C6 and stabilization of C5/7 were performed with a combination of cage and plate. At an outpatient control 16 months after reoperation, the patient complained of neck pain, while the control X-ray showed a fracture of the implant...

Intervertebral disc (IVD) degeneration that accelerates the loss of disc structural and functional integrities is recognized as one of the major factors of chronic back pain. Cardiovascular risk factors, such as deficits of apolipoproteins that elevate the levels of cholesterol and triglycerides, are considered critical for the progress of atherosclerosis; notably in the abdominal aorta and its lumbar branching arteries that supply lumbar vertebrae and IVDs. Obstruction of the lumbar arteries by atherosclerosis is presumed to promote lumbar disc degeneration and low back pain...

Dense biomaterial plays an important role in bone replacement. However, it fails to induce bone-cell migration into graft material. In the present study, a novel bone-graft substitute (BGS) consisting of porous gradient HA/ZrO2 composite (PGHC) and gelatin/chitosan slow-release hydrogel containing BMP-2 and BMSCs was designed and prepared to repair lumbar vertebral defects. The morphological characteristics of the BGS evaluated by scanning electron microscope showed that it had a three-dimensional network structure with uniformly distributed chitosan microspheres on the surfaces of the graft material and the interior of the pores...

The most common reason that adults in the United States see their physician is lower back or neck pain secondary to degenerative disc disease. To date, approaches to treat degenerative disc disease are confined to purely mechanical devices designed to either eliminate or enable flexibility of the diseased motion segment. Tissue engineered intervertebral discs (TE-IVDs) have been proposed as an alternative approach and have shown promise in replacing native IVD in the rodent tail spine. Here we demonstrate the efficacy of our TE-IVDs in the canine cervical spine...

PURPOSE: In adults, growth hormone deficiency (GHD) has been associated with low bone mineral density (BMD), an effect counteracted by growth hormone (GH) replacement. Whether GH is beneficial in adults with age-related bone loss and without hypopituitarism is unclear. METHODS: We conducted a systematic literature search using Medline, Embase and the Cochrane Register of Controlled Trials. We extracted and analyzed data according to the bone outcome included [bone mineral content (BMC), BMD, and bone biomarker, fracture risk]...

BACKGROUND: In the treatment of early onset scoliosis (EOS), there has been a trend to use magnetically controlled growing rods (MCGR) in order to reduce the number of surgeries. To confirm the amount of lengthening, spine radiographs were required. Recently, ultrasound (US) has been added to monitor lengthening of MCGR to avoid radiation exposure. Our aim was to determine whether US is as accurate as plain radiography (x-ray) in determining the amount of length achieved at individual MCGR lengthening episodes...

BACKGROUND: Treatment of thoracic spinal dural arteriovenous fistulas (DAVFs) by microsurgery has recently been approached using minimally invasive spine surgery (MISS). The advantages of such an approach are offset by difficult maneuverability within the tubular retractor and by the creation of "tunnel vision" with reduced luminosity to a remote surgical target. OBJECTIVE: To demonstrate how the pitfalls of MISS can be addressed by applying 3-D endoscopy to the minimally invasive approach of spinal DAVFs...

OBJECTIVE Spinal deformity has become a well-recognized complication of intramedullary spinal cord tumor (IMSCT) resection. In particular, laminectomy can result in biomechanical instability caused by loss of the posterior tension band. Therefore, laminoplasty has been proposed as an alternative to laminectomy. Here, the authors describe the largest current series of pediatric patients who have undergone laminoplasty for IMSCT resection and investigate the need for surgical fusion after both laminectomy and laminoplasty...

During level walking, arm swing plays a key role in improving dynamic stability. In vivo investigations with a telemeterized vertebral body replacement showed that spinal loads can be affected by differences in arm positions during sitting and standing. However, little is known about how arm swing could influence the lumbar spine and hip joint forces and motions during walking. The present study aims to provide better understanding of the contribution of the upper limbs to human gait, investigating ranges of motion and joint reaction forces...
