RESUMEN
Study Design: This was a retrospective longitudinal observational study. Purpose: The purpose of this study was to analyze the results of cervical sagittal parameters on preoperative and postoperative lateral radiographs in anterior cervical discectomy and fusion (ACDF). ACDF is believed to change craniocervical parameters and thus cervical curvature using polyetheretherketone (PEEK) or titanium cages with or without self-locking as well as an anterior plate, the latter of which has not been shown to provide better clinical or radiological results. Overview of Literature: Cervical spondylotic myelopathy (CSM) is a common degenerative pathology that can affect one or more levels and treatment has varied over time trying to maintain sagittal parameters within acceptable values where the ACDF is the main treatment. Materials and Methods: The study was performed in patients with CSM who underwent anterior cervical discectomy, and their pre- and postoperative radiographs were analyzed using Surgimap software a few days before and 3 months after surgery. Results: Fifteen files were included in the study. Statistically significant sagittal balance variables were observed in cervical lordosis (CL) with an increase of 4.73° (P = 0.019) and T1 slope (T1S)-CL with a decrease of -5.93° (P = 0.007). Conclusions: CL and T1S-CL showed favorably modified values when performing ACDF using stand-alone PEEK cages without the need for self-blocking or an anterior plate.
RESUMEN
Background: Hemangioblastomas are benign tumors that develop in the central nervous system. They represent 1.5-2.5% of all intracranial tumors, and about 2-15% of all spinal cord tumors. They are highly associated with von Hippel-Lindau disease. Case Description: A 36-year-old female presented with a 4-year history of progressive right upper extremity distal weakness and cervical pain. The magnetic resonance imaging demonstrated a homogeneously, contrast enhancing intradural/intramedullary tumor at C6-C7 with perilesional edema and a syrinx accompanied by a cerebellar cyst with a mural nodule. Surgery included excision of the spinal lesion and decompression and excision of the cerebellar cyst and mural nodule (i.e., median suboccipital craniectomy and cervical C5-C7 laminectomy). Conclusion: Surgery is the gold standard treatment for symptomatic hemangioblastomas, and surgical approaches should minimize risk.
RESUMEN
This 20 years old male patient with a history of Hodgkin's disease since 1996, stage II variety nodular sclerosis, was initially managed with radiotherapy and chemotherapy ending such treatment in January 1997, subsequently treated with interferon for one year, ending in January 1998, presented complete remission and was maintained in observation; in June 1999 started with thoracolumbar pain, weakness and diminished sensitivity on lower limbs, studies were conducted and diagnosed epidural tumor from levels T9 to T12, with important spinal cord compression; the patient was submitted to surgery and neurological recovery was complete.
