New surgical approach for late complications from spinal cord injury
BACKGROUND: The most frequent late complications in spinal cord injury result from arachnoiditis and consequent alterations in dynamics of cerebrospinal fluid flow. A surgical procedure carried out on patients with these alterations, resolved the various pathologies more efficiently in all cases. METHODS: From October 2000 to March 2006, 23 patients were selected for surgery: three showed signs of syringomyelia, three presented with microcystic lesions, three presented with arachnoid cysts in different locations but always confluent to the scar area, and 14 showed evidence of tethered cords. The surgery consisted of laminectomy at four levels, followed by dural opening in order to remove all the arachnoiditis at the level of the scar and to remove the altered arachnoid and its cysts, at least at two levels above and below the lesion. The dentate ligaments were cut at all exposed levels. RESULTS: The patients had no postoperative problems and not only retained all neurological functions but also showed neurological recovery. According to the motor and sensory scale of the American Spinal Injury Association, the recoveries were motor 20.6% (P < 0.001), touch 15.6% ((P < 0.001) and pinprick 14.4% (P < 0.001). These patients showed no signs of relapse at 4–66 month follow-up. CONCLUSION: This alternative surgery resolved the pathologies provoking neurological deterioration by releasing the complete spinal cord at the level of the scar and the levels above and below it. It thus avoids myelotomies and the use of shunts and stents, which have a high long-term failure rate and consequent relapses. Nevertheless, this surgical procedure allows patients the chance to opt for any further treatment that may evolve in the future
Posttraumatic spinal cord tethering and syringomyelia: surgical treatment and long-term outcome

Neurosurgical untethering with or without syrinx drainage results in high patient satisfaction and favorable clinical outcome in post-traumatic myelopathy patients
Study design: Retrospective data collection and patient-reported outcome measures. Objectives: To investigate surgical outcome, complications, and patient satisfaction in patients with chronic SCI and symptomatic post-traumatic progressive myelopathy (PPM) who underwent neurosurgical untethering and/or spinal cord cyst drainage with the aim of preventing further neurological deterioration. Setting: Single-center study at an academic neurosurgery department. Methods: All SCI patients who underwent neurosurgery between 1996 and 2013 were retrospectively included. All medical charts and the treating surgeon’s operative reports were reviewed to identify surgical indications, surgical technique, and post-operative complications. A questionnaire and an EQ-5D-instrument were used to assess patient's self-described health status and satisfaction at long-term follow-up. Results: Fifty-two patients (43 men, 9 women) were identified, of whom five were dead and one was lost to follow-up. Main indications for surgery were pain (54%), motor (37%), or sensory (8%) impairment, and spasticity (2.0%). Overall complications were rare (8%). At follow-up, the subjectively perceived outcome was improved in 24 and remained unchanged in 21 patients. Thus, the surgical aim was met in 87% of patients. Of the 46 eligible patients, 38 responded to the questionnaire of whom 65% were satisfied with the surgical results. Patients with cervical lesions were more satisfied with the surgical treatment than patients with thoracic/thoracolumbar lesions (p = 0.05). Conclusions: Neurosurgical untethering and/or cyst drainage in chronic SCI patients and PPM resulted in a high degree of patient satisfaction, particularly in cervical SCI patients with minimal complications
The translational dialogue in spinal cord injury research
Background: Although the emphasis in clinical spinal cord injury (SCI) research has been directed towards the evaluation of clinical assessments (standards in neurological examination) and the appreciation of outcome measures (that is, extent and pattern of clinical recovery from SCI), the underlying neurological mechanisms for recovery from SCI are not well documented in humans. However, to improve the translational research, a meaningful preclinical-clinical dialogue is required, with an appreciation for both fundamental neural mechanisms and what makes human SCI unique. This holds true both for potential interventions in rehabilitation and novel drug or cell-based treatment approaches in acute SCI.Objectives:The gap in translational research that needs to be approached from both ends not only includes the appreciation of principal neural mechanisms (repair, sprouting, plasticity) and their assumed impact onto outcomes (even though humans and non primate animals may rely on slightly different supraspinal control for some movements), but also includes an understanding of the spatial (location and size of lesion) and temporal (timelines of damage and recovery) factors in spinal cord damage that can vary considerably between the different species being studied.Conclusion:The preclinical-clinical dialogue should be encouraged as a venue to improve the appreciation of discoveries in basic research, and to power valid discoveries towards a meaningful translation into advanced treatments downstream. Similarly, the upstream identification of appropriate clinical targets that take into account clinical constraints depends on reliable and advanced clinical information being provided to preclinical investigators.Spinal Cord advance online publication, 8 November 2011; doi:10.1038/sc.2011.113
