RESUMO
Up-to-date management for metastatic epidural spinal cord compression is based on appropriate scoring systems. In this case, separation surgery and stereotactic radiosurgery achieved an optimized outcome. A 75-year-old man had thoracic band-like pain, left lower limb weakness and difficulty ambulating for 6 weeks. Spinal images showed a T4 metastatic epidural spinal cord compression with a pathological fracture of T4 and T10 and L3 lytic lesions. There was no other neoplastic lesion. The metastasized T4 was decompressed by a posterolateral right costotransversectomy, vertebrectomy and insertion of an expandable titanium cage. The spinal sagittal alignment was restored with T1-T7 pedicle screw fixation. Post-operatively the pain and motor power improved significantly so that the patient was discharged home. Separation surgery and adjuvant stereotactic radiosurgery of the spine successfully improved tumor burden, pain control and overall prognosis.
RESUMO
Total vertebrectomy with spine shortening has been reported for the treatment of difficult cases of traumatic spine dislocation, both in acute and chronic phase. We report an exceptional case of a five-week-old T12-L1 spine dislocation in a 25-year-old female with complete paraplegia as a result of trauma in Ciudad de León (Nicaragua). In view of the time since the dislocation, we performed a complete L1 vertebrectomy in order to reduce the dorsolumbar hinge. For osteosynthesis material we had only eight screws and two Steffee plates. We therefore introduced pedicle screws at levels T11, T12, L2 and L3 on the right side and T11, T12, L3 and L4 on the left, and performed manual reduction of the spine. Steffee plates were placed and we added sublaminar wires to reinforce the osteosynthesis. Fifteen months after surgery, there has been no neurological improvement.

OBJECTIVE: To analyze the clinical results of a partial vertebrectomy with titanium mesh implantation and pedicle screw fixation using a posterior approach to reconstruct the spine in the treatment of thoracolumbar burst fractures. METHOD: From January 2006 to August 2008, 20 patients with severe thoracolumbar fractures were treated.For vertebral bodies associated with one injured intervertebral disk, subtotal vertebrectomy surgery and single-segment fusion were performed. For vertebral bodies with two injured adjacent intervertebral disks, partial vertebrectomy surgery and two-segment fusion were performed. RESULTS: All 20 patients were followed up for 12 to 24 months (average of 18 months). There were no complications such as wound infections, hemopneumothorax or abdominal infections in any of the patients. The neurological status of all of the patients was improved by at least one American Spinal Injury Association grade by the last follow-up. The anterior vertebral body height was an average of 50.77% before surgery, 88.51% after surgery and 87.86% at the last follow up; the sagittal Cobb angle was improved, on average, from 26.15° to 5.39° and was 5.90° at the last follow up. The percentage of spinal stenosis was improved, on average, from 26.07% to 4.93%° and was 6.15% at the last follow up. There were significant differences ...

INTRODUCCIÓN. El objeto de este estudio fue analizar la evolución clínica de una serie de pacientes con fracturas vertebrales postraumáticas y trastornos neurológicos añadidos, operados mediante la técnica de corpectomía transpedicular, y relacionar además esta evolución con el tiempo preoperatorio transcurrido. MÉTODOS. Se realizó un estudio prospectivo de intervención, de 18 pacientes con paraplejia postraumática, a los cuales se les realizó descompresión medular por corpectomía transpedicular e instrumentación con la técnica de Luque. Los pacientes fueron atendidos entre 1987 y 1989 en el Hospital «Hermanos Ameijeiras¼. RESULTADOS. De 15 pacientes que no deambulaban, 9 recuperaron esa función (60 %). No se halló relación entre el tiempo de la lesión y la recuperación neurológica. La complicación más frecuente fue la infección, y hubo un fallecido. El tiempo promedio de duración de la lesión fue de 11,7 meses, y el tiempo promedio de evolución posoperatoria fue de 10,7 meses. CONCLUSIONES. Se concluyó que la descompresión del canal y la instrumentación vertebral en pacientes con lesiones medulares postraumáticas puede mejorar el estado neurológico de éstos, independientemente del tiempo de lesión preoperatorio.
INTRODUCTION: The aim of present study was to analyze the clinical course of a group of patients presenting with post-traumatic vertebral fractures and added neurologic disorders operated on by transpedicular vertebrectomy and to relate this course to intervening preoperative time. METHODS: An interventional and descriptive study was conducted in 18 patients presenting with post-traumatic paraplegia underwent medullar decompression by transpedicular vertebrectomy and instrumentation using Luque’s technique. Patients were seen in “Hermanos Ameijeiras” Clinical Surgical Hospital from 1987 to 1989. RESULTS: From 15 non-ambulatory patients 9 recovered that function (60%). There was not relation between the lesion time and neurologic recovery. The more frequent complication was the infection with deceased patient. Mean time of lesion duration was of 11,7 months, and the mean time of postoperative course was of 10,7months. CONCLUSIONS: We conclude that canal decompression and vertebral instrumentation in patients presenting with post-traumatic lesions, can to improve the neurologic status independently of preoperative lesion time.
INTRODUCTION. Le but de cette étude est d'analyser l'évolution clinique d'une série de patients atteints de fractures vertébrales post-traumatiques et de troubles neurologiques qui ont été opérés par la technique de corpectomie transpédiculaire, et d'associer aussi cette évolution au temps préopératoire écoulé. MÉTHODES. Une étude prospective de 18 patients atteints de paraplégie post-traumatique et traités par décompression médullaire (corpectomie transpédiculaire et instrumentation), selon la technique de Luque, a été réalisée. Les patients ont été soignés entre 1987 et 1989 à l'Hôpital “Hermanos Ameijeiras”. RÉSULTATS. Neuf patients sur quinze ont récupéré cette fonction (60%). Il n'y a pas eu de relation entre le temps de la lésion et la récupération neurologique. La complication la plus fréquente a été l'infection, et un patient est décédé. Le temps moyen de la lésion a été 11,7 mois tandis que le temps moyen de l'évolution postopératoire a été 10,7 mois. CONCLUSIONS. On a conclu que la décompression du canal et la instrumentation rachidienne chez des patients atteints des lésions médullaires post-traumatiques peuvent améliorer leur état neurologique, indépendemment du temps préopératoire de la lésion.
