The use of opioids among patients with workers' compensation claims is associated with tremendous costs, especially for patients who undergo spinal surgery. This study compared return-to-work rates after single-level cervical fusion for degenerative disk disease between patients who received opioids before surgery and patients who underwent fusion with no previous opioid use. All study subjects qualified for workers' compensation benefits for injuries sustained at work between 1993 and 2011. The study population included 281 subjects who underwent single-level cervical fusion for degenerative disk disease with International Classification of Diseases, Ninth Revision, and Current Procedural Terminology code algorithms...

Baastrup's disease is an uncommon entity in the elderly spine and it is very rare in the pediatric age group. There are only few case reports in the literature containing Baastrup's disease in pediatric spine. Baastrup's disease is also known as kissing spine because the posterior spinous processes touch or "kiss" one another, characterized by enlarged posterior spinous projections with normal neuroforamina and normal spinal disk height. There are various pathological and etiological hypotheses behind Baastrup's disease...

OBJECTIVE: To assess feasibility and accuracy of a new insertion technique of S1 transpedicular screw. SUMMARY OF BACKGROUND DATA: Transpedicular stabilization in the first sacral vertebra (S1) is a technically demanding surgical procedure with inherent risk of loosening of the implant. A modification of the technique was recently proposed, along with the analytical verification which was performed based on the available literature. In the study, we performed radiological assessment of screws inserted into the S1 using the classical and modified techniques...

BACKGROUND: The spinal column including its vertebrae and disks has been well examined and extensively reported in relation to age-aggregated degeneration. In contrast, paravertebral muscles are poorly represented in describing normative degeneration. Increasing evidence points to the importance of paravertebral muscle quality in low back health, and their potential as a modifiable factor in low back pain (LBP). Studies examining normative decline of paravertebral muscles are needed to advance the field's etiological understanding...

HYPOTHESIS: Silicon substituted hydroxyapatites (SiHA) are highly crystalline bioceramics treated at high temperatures (about 1200°C) which have been approved for clinical use with spinal, orthopedic, periodontal, oral and craniomaxillofacial applications. The preparation of SiHA with lower temperature methods (about 700°C) provides nanocrystalline SiHA (nano-SiHA) with enhanced bioreactivity due to higher surface area and smaller crystal size. The aim of this study has been to know the nanocrystallinity effects on the response of both osteoblasts and osteoclasts (the two main cell types involved in bone remodelling) to silicon substituted hydroxyapatite...

Infections of the spine may involve different anatomic compartments, including intervertebral disks, vertebral bone, paraspinal soft tissues, epidural space, meninges, and spinal cord. This article focuses on the role of imaging in diagnosis and follow-up of infections of the intervertebral disk and vertebral bone, named respectively diskitis and spondylitis or vertebral osteomyelitis. Often, at the time of diagnosis, the infection already involves both structures; therefore the process is referred as spondylodiskitis...

Background Postoperative epidural fibrosis (PEF) localized around the exposed dura and nerve roots is a known radiologic entity seen after lumbar surgery. Although excessive PEF is associated with residual and new lumbar pain and radiculopathy, its role as the generator of the pain is still discussed. Various materials acting as an adhesion barrier have been tested. There is no undebated class I evidence that any one of them is suitable to reduce or avoid PEF and provide a better clinical outcome. In revision surgery, the dissection of epidural scar tissue is time consuming and related to an elevated risk of dural tear and nerve damage...

Iatrogenic vascular injury during lumbar spinal surgery is rare, but may lead to serious complications in unrecognized cases. Especially, injuries to aorta or its major branches may result in death unless diagnosed and treated immediately. We present a rare case of aortic injury with a scalpel in a 56-year-old male patient undergoing lumbar disk surgery. The vascular injury was successfully treated with open surgery. The post-operative period was uneventful and the patient was discharged in a healthy condition on the 8th day...
