OBJECTIVE Adverse events related to spine surgery sometimes lead to litigation. Few studies have evaluated the association between spine surgical complications and medical malpractice proceedings, outcomes, and awards. The aim of this study was to identify the most frequent causes of alleged malpractice in spine surgery and to gain insight into patient demographic and clinical characteristics associated with medical negligence litigation. METHODS A search for "spine surgery" spanning February 1988 to May 2015 was conducted utilizing the medicolegal research service VerdictSearch (ALM Media Properties, LLC)...

PURPOSE: Surgical intervention is a treatment option for various spinal pathology but many patients report no improvement or even an exacerbation of symptoms like pain. This study examined the association of preoperative (pre-op) biopsychosocial risk factors with poor quality of life at 2 and 6 months using hierarchical models controlling demographic and medical variables. METHOD: Participants undergoing thoracolumbar spine surgery (N = 214) were provided with questionnaire packages to complete pre-op, at 2 and at 6-month postoperative clinical follow-ups (i...

INTRODUCTION: Recent studies have demonstrated the neuroprotective and immunomodulatory effects of 1,25-dihydroxyvitamin D3 (calcitriol), but no previous study has examined these effects on spinal cord ischemia/reperfusion (I/R) injury. Therefore, the present study aimed to evaluate whether calcitriol protects the spinal cord from I/R injury. METHODS: Rabbits were randomized into four groups of eight animals: group 1 (laparotomy control), group 2 (ischemia control), group 3 (30mg/kg intraperitoneal methylprednisolone at surgery), and group 4 (0...

BACKGROUND: Lumbar microdiscectomy is the most commonly performed spinal surgery procedure, with over 300,000 cases performed annually in the United States alone. Traditionally, patients were advised to restrict post-operative activity as this was believed to reduce the risk of disc reherniation and progressive instability. However, this practice would often delay patients return to work. In contemporary practice many surgeons do not restrict patient post-operative activity due to the perception this practice is unnecessary...

In a consensus process during four sessions in 2016, the working group "lower cervical spine" of the German Society for Orthopedic and Trauma Surgery (DGOU), formulated "Therapeutic Recommendations for the Lower Cervical Spine", taking into consideration the current literature. Therapeutic goals are a permanently stable, painless cervical spine and the protection against secondary neurologic damage while retaining the greatest possible amount of motion and spinal profile. Due to its ease of use and its proven good reliability, the AOSpine classification for subaxial cervical injuries should be used...

Primary non-Hodgkin's lymphoma of the vertebra is rare in the spine of the elderly. The clinical presentation and radiological features are unspecific, which make it more difficult for diagnosis. We report a case of a 79-year-old woman complaining of serious backache without any injury. The magnetic resonance imaging (MRI) showed invasion of the fifth thoracic vertebra with the posterior vertebral body wall defect. There was a high suspicion that the patient had a metastatic tumor of the vertebra. A percutaneous vertebroplasty was performed under fluoroscopic guidance, which was used to treat the osteoporotic vertebral compression fracture, vertebral metastases, verte-bral hemangioma, and multiple myeloma...

BACKGROUND: The most common causes of pain following lumbar spinal fusions are residual herniation, or foraminal fibrosis and foraminal stenosis that is ignored, untreated, or undertreated. The original surgeon may advise his patient that nothing more can be done in his opinion that the nerve was visually decompressed by the original surgery. Post-operative imaging or electrophysiological assessment may be inadequate to explain all the reasons for residual or recurrent symptoms. Treatment of failed lumbar spinal fusions by repeat traditional open revision surgery usually incorporates more extensive decompression causing increased instability and back pain...

BACKGROUND: Currently, many scholars are concerned about the treatment of postoperative infection; however, few have completed multivariate analyses to determine factors that contribute to the risk of infection. Therefore, we conducted a multivariate analysis of a retrospectively collected database to analyze the risk factors for acute surgical site infection following lumbar surgery, including fracture fixation, lumbar fusion, and minimally invasive lumbar surgery. METHODS: We retrospectively reviewed data from patients who underwent lumbar surgery between 2014 and 2016, including lumbar fusion, internal fracture fixation, and minimally invasive surgery in our hospital's spinal surgery unit...

We previously showed that activation of G protein-coupled receptor 40/free fatty acid receptor 1 (GPR40/FFAR1) signaling modulates descending inhibition of pain. In this study, we investigated the involvement of fatty acid-GPR40/FFAR1 signaling in the transition from acute to chronic pain. We used GPR40/FFAR1-knockout (GPR40KO) mice and wild-type (WT) mice. A plantar incision was performed, and mechanical allodynia and thermal hyperalgesia were evaluated with a von Frey filament test and plantar test, respectively...

STUDY DESIGN: In Vitro Study. OBJECTIVE: To evaluate the effect that factors released from human posterior spinal bone dust have on primary human osteoblast growth and maturation. SUMMARY OF BACKGROUND DATA: Bone dust, created during spinal fusion surgeries has the potential to be used as an autologous bone graft by providing a source of viable autologous osteoblasts and mesenchymal stem cells with osteogenic potential. To date, no information is available on whether bone dust also provides a source of anabolic factors with the potential to enhance osteoblast proliferation and maturation, which would enhance its therapeutic potential...

In cervical artificial disc replacement (C-ADR), sometimes we encountered with such cases that implants of adjacent height both fit the target disc space properly. No study was available discussing the choice of implant height and the clinical outcomes under such circumstance. The purpose of this study was to evaluate the impact of different implant heights on the clinical outcomes and radiographic results when the implants of adjacent height both fit the disc space properly. This retrospective study included 34 patients underwent single-level C-ADR at the C5-C6 level at our institution...

BACKGROUND: Pedicle screw fixation in high grade lumbar listhetic vertebral body has been nightmare for Orthopaedic and spine surgeons. This is because of abnormally positioned listhetic pedicles and non-visualization of pedicle in conventional image intensifier (C-Arm). This results into increased surgical time, more blood loss, radiation exposure and more chances of infection. To overcome this problem, we have devised a new Technique of putting of pedicle screw fixation in listhetic vertebrae...

The use of free flaps is considered the "gold standard" for reconstruction of head and neck defects. Locoregional flaps allows a better aesthetic result compared to free flaps, whenever there's an external skin defect. However the use of free flaps is not always adequate in the presence of preoperative comorbidities or previous surgeries. Since the description of the trapezius myocutaneous flap in the 1980's, many authors have published the results of the applicability of this flap in head and neck salvage reconstructive surgery...

N Rath, B Balain
Acute spinal cord injury (ASCI) is common and no consensuses have been reached regarding timing of surgical decompression. This article highlights the main issues regarding surgical management of ASCI patients. The importance of timing of surgery along with physiological stability of the cord, and indications for surgery has been discussed to facilitate better understanding of the condition. The importance of the type of injury to the spinal column, besides the cord injury, is also discussed. A brief review of relevant literature has been done to try and answer the question whether early or late surgical treatment for ASCI is better than conservative management, reflecting the ethos of treatment for these problems in Robert Jones And Agnes Hunt Orthopaedic Hospital in Oswestry...

A young amateur wrestler presented with a burst fracture of the seventh cervical vertebra with complete paraplegia. He was treated with surgery for spine stabilisation and was actively rehabilitated. Adolescents and teenagers are indulging in high-contact sports like wrestling, without proper training and technical know-how, which can lead to severe injuries and possibly, permanent handicap or death. Trainers, assistants and institutions should be well equipped to diagnose and provide initial care of people with a spinal injury to prevent a partial injury from progressing to complete injury...

BACKGROUND: Approximately 33% of the patients with lumbar spinal stenosis (LSS) who undergo surgery are not satisfied with their postoperative clinical outcomes. Therefore, identifying predictors for postoperative outcome and groups of patients who will benefit from the surgical intervention is of significant clinical benefit. However, many of the studied predictors to date suffer from subjective recall bias, lack fine digital measures, and yield poor correlation to outcomes. METHODS: This study utilized smart-shoes to capture gait parameters extracted preoperatively during a 10 m self-paced walking test, which was hypothesized to provide objective, digital measurements regarding the level of gait impairment caused by LSS symptoms, with the goal of predicting postoperative outcomes in a cohort of LSS patients who received lumbar decompression and/or fusion surgery...
