- To evaluate survival after surgery and indications for surgery due to spinal metastatic disease.A retrospective longitudinal multiregistry nationwide cohort study.19 public hospitals in Sweden with spine surgery service, where 6 university hospitals account for over 90% of the cases.1820 patients 18 years or older undergoing surgery due to spinal metastatic disease 2006-2018 and registered in Swespine, the Swedish national spine surgery registry.Decompressive and/or stabilising spine surgery due to spinal metastatic disease.Survival (median and mean) after surgery.Indications for surgery, types of surgery and causes of death.The median estimated survival after surgery was 6.2 months (95% CI: 5.6 to 6.8) and the mean estimated survival time was 12.2 months (95% CI: 11.4 to 13.1). Neurologic deficit was the most common indication for surgery and posterior stabilisation was performed in 70.5% of the cases. A neoplasm was stated as the main cause of death for 97% of the patients.Both median and mean survival times were well above the generally accepted thresholds for surgical treatment for spinal metastases, suggesting that patient selection for surgical treatment on a national level is adequate. Further research on quality of life after surgery and prognostication is needed.

- Case report.To present an unusual traumatic neurologic pathology caused by gunshot injury.Spine unit of Department of Trauma and Orthopaedic Surgery, University Medical School, Charité - Campus Benjamin Franklin, Berlin, Germany.A 35-year-old male sustained a gunshot injury from a machine gun. The projectile caused a fracture of the left pedicle of Th10. The spinal cord was indirectly damaged by cavitation that caused a Brown-Séquard syndrome (BSS). After a microscopically assisted posterior revision at T9/10 with removal of bullet and bone fragments from the spinal canal and debridement of the bullet cavity via extended fenestrectomy the patient gained his motor function back. The sensory deficit remained unchanged.BSS can be caused by bullet-related injury of the spinal canal with no direct damage of neural structures. The initial treatment is always based on the total injury pattern. Possible spinal cord injuries are only clarified after restitution of vital functions. Decompression of neural structures in shotgun injury is indicated in incomplete paraplegia, injury of intra-abdominal hollow organs or high velocity bullet wounds. Through debridement and decompression of neural structures and chronic damage caused by foreign body granulomas can be prevented. Secondary destabilization of the spine should be avoided.

- Posttraumatic anemia in multiply injured patients is caused by hemorrhage, reduced red blood cell survival, and impaired erythropoiesis. Trauma-induced hyperinflammation causes impaired bone-marrow function by means of blunted erythropoietin (EPO) response, reduced iron availability, suppression and egress of erythroid progenitor cells. To treat posttraumatic anemia in severely injured patients, symptomatic therapy by blood transfusion is not sufficient. Furthermore, EPO, iron, and the use of red cell substitutes should be considered. The posttraumatic systemic inflammatory response syndrome (SIRS) induces posttraumatic anemia. Thus, a worsening of SIRS by a "second-hit" through blood transfusion ought to be avoided.

- Postoperative spinal infections are relatively rare. They can become life-threatening.A 56-year-old man developed multisegmental spinal infection with methicillin-resistant Staphylococcus aureus after discectomy at L3/4. A staged ventrodorsoventral intervention was needed for radical debridement and stabilization. After femoral head necrosis developed as a result of the infection, a Girdlestone hip was maintained until the joint was aseptic and a hip prosthesis could be implanted. Two years postoperatively, the patient remained free of infection recurrence.Radical debridement and a tightly controlled antibiotic regimen are necessary for the management of postoperative spinal infections. This should include staged interventions until recovery from infection is possible. Early intervention can prevent systemic sepsis caused by widespread bacterial dissemination.

- The purpose of this study was to investigate the outcome of expandable titanium cage implantation in large defects caused by acute vertebral osteomyelitis. Twenty-five patients with acute single or multilevel spondylodiscitis were treated after radical débridement and posterior instrumentation with an anterior expandable titanium cage and bone grafting. Clinical, laboratory and radiological follow-up continued for 36 months. Within the postoperative course there was no recurrence of spinal infection. The final radiological examination showed successful fusion in all cases without implant loosening or failure. At the final follow-up after 36 months the Oswestry Disability Index was 23 +/- 14 and the pain visual analogue scale 2.1 +/- 1.7. This study reveals healing and improved function after expandable titanium cage implantation in all patients. Prerequisites for optimal healing include radical débridement, provision of stability for weight-bearing, adequate bone grafting and correction of deformity using rigid implants.

- The use of metal implants in large defects caused by spinal infection to support the anterior column is controversial, and relatively few results have been published to date. Despite the fact that there is bacterial adhesion to metal implants, the strong immunity of the highly vascularized spine because of rich muscle covering is unique. This possibly allows the use of metal implants, which have the advantage of high stability and reduced loss of correction. This is a retrospective study of patients with spondylodiscitis treated with metal implants.We retrospectively analyzed the outcome in 22 consecutive patients (mean age 69 (43-82) years, 15 men) with spondylodiscitis (20 lumbar and 12 thoracic discs) who had received an anterior titanium cage implantation. In 13 cases, the pathogen could be identified. Antibiotic treatment was continued for at least 12 weeks postoperatively.The mean follow-up was 36 (32-47) months. Healing of inflammation was confirmed by clinical, radiographic, and laboratory parameters. The mean VAS improved from 9.1 (6-10) preoperatively to 2.6 (0-6) at the final follow-up, and the mean Oswestry disability index was 17 (0-76) at the final follow-up.Our findings highlight the high healing rate and stability when titanium implants are used. Prerequisites are a radical debridement, correction of deformity, and additional bony fusion by bone grafting. The increased stability, with facilitated patient mobilization, and the relatively little loss of correction using anterior and posterior implants are of considerable advantage in the treatment of the patients with multiple co-morbidities.

- STUDY DESIGN: Retrospective cohort study.OBJECTIVE: To validate the precision of four predictive scoring systems for spinal metastatic disease and evaluate whether they underestimate or overestimate survival.SUMMARY OF BACKGROUND DATA: Metastatic spine disease is a common complication to malignancies. Several scoring systems are available to predict survival and to help the clinician to select surgical or nonsurgical treatment.METHODS: Three hundred fifteen adult patients (213 men, 102 women, mean age 67 yr) undergoing spinal surgery at Uppsala University Hospital, Sweden, due to metastatic spine disease 2006 to 2012 were included. Data were collected prospectively for the Swedish Spine Register and retrospectively from the medical records. Tokuhashi scores, Revised Tokuhashi Scores, Tomita scores, and Modified Bauer Scores were calculated and compared with actual survival data from the Swedish Population Register.RESULTS: The mean estimated survival time after surgery for all patients included was 12.4 months (confidence interval 10.6-14.2) and median 5.9 months (confidence interval 4.5-7.3). All four scores had significant correlation to survival (P < 0.0001) but tended to underestimate rather than overestimate survival. Modified Bauer Score was the best of the four scores to predict short survival, both regarding median and mean survival. Tokuhashi score was found to be the best of the scores to predict long survival, even though the predictions were inaccurate in 42% of the cases.CONCLUSION: Predictive scores underestimate survival for the patients which might affect important clinical decisions.LEVEL OF EVIDENCE: 3.

- Epidural analgesia with bupivacain, epinephrine and fentanyl provides excellent pain control after lumbar fusion surgery, but pruritus and motor block are frequent side effects. Theoretically epidural ropivacain combined with oral oxycodone could decrease the incidence of these side effects. The two regimens were compared in a prospective randomized trial.150 patients (87 women) treated with posterior instrumented lumbar fusion were included. The mean age was 51 +/- 11 years. 76 were randomized to bupivacain, epinephrine and fentanyl (group B) and 74 to ropivacain and oxycodone (group R). Pruritus, motor block and pain were measured 6 hours after surgery, thereafter 6 times per day for 5 days. Any pain breakthrough episode was registered whenever it occurred.The epidural treatment could be performed in 143 patients (72 in group B and 71 in group R). Disturbing pruritus occurred in 53 patients in group B compared to 12 in group R (p < 0.0001). Motor blockade was most frequent on day 1, occurring in 45% of the patients with no difference between the groups. Both regimes gave good pain control with average VAS under 40, but the pain relief was statistically better in group B. The number of pain breakthrough episodes did not differ between the groups.Pruritus could be reduced with a combination of epidural ropivacain and oral oxycodone, at the price of a slightly higher pain level. Ropivacaine was not found to be superior to bupivacaine with regard to motor blocks.

- Patients with ankylosing spondylitis are at significant risk for sustaining cervical spine injuries following trauma predisposed by kyphosis, stiffness and osteoporotic bone quality of the spine. The risk of sustaining neurological deficits in this patient population is higher than average. The present review article provides an outline on the specific injury patterns in the cervical spine, diagnostic algorithms and specific treatment modalities dictated by the underlying disease in patients with ankylosing spondylitis. An emphasis is placed on the risks and complication patterns in the treatment of these rare, but challenging injuries.

- The innate immune response to trauma hemorrhage involves inflammatory mediators, thus promoting cellular dysfunction as well as cell death in diverse tissues. These effects ultimately bear the risk of post-traumatic complications such as organ dysfunction, multiple organ failure, or adult respiratory distress syndrome. In this study, a murine model of resuscitated hemorrhagic shock (HS) was used to determine the apoptosis in spleen as a marker of cellular injury and reduced immune functions.Male C57BL-6 mice were subjected to sham operation or resuscitated HS. At t = 0 hours, t = 24 hours, and t = 72 hours, mice were euthanized and the spleens were removed and evaluated for apoptotic changes via DNA fragmentation, caspase activities, and activation of both extrinsic and intrinsic apoptotic pathways. Spleens from untreated mice were used as control samples.HS was associated with distinct lymphocytopenia as early as t = 0 hours after hemorrhage without regaining baseline levels within the consecutive 72 hours when compared with sham and control groups. A rapid activation of splenic apoptosis in HS mice was observed at t = 0 hours and t = 72 hours after hemorrhage and predominantly confirmed by increased DNA fragmentation, elevated caspase-3/7, caspase-8, and caspase-9 activities, and enhanced expression of intrinsic mitochondrial proteins. Accordingly, mitochondrial pro-apoptotic Bax and anti-apoptotic Bcl-2 proteins were inversely expressed within the 72-hour observation period, thereby supporting significant pro-apoptotic changes. Solely at t = 24 hours, expression of the anti-apoptotic Mcl-1 protein shows a significant increase when compared with sham-operated and control animals. Furthermore, expression of extrinsic death receptors were only slightly increased.Our data suggest that HS induces apoptotic changes in spleen through a biphasic caspase-dependent mechanism and imply a detrimental imbalance of pro- and anti-apoptotic mitochondrial proteins Bax, Bcl-2, and Mcl-1, thereby promoting post-traumatic immunosuppression.
