Circumferential approach has been well described in the literature but long terms outcomes are not well reported. Important to decide the correct treatment option is the preoperative radiological exams to value the type of deformity(flexible or fixed). We report the case of a 67-year-old woman affected by a severe cervical kyphotic deformity who underwent combined anterior/posterior surgical approach, getting a good reduction of the deformity and an optimal stability in a long term follow up.展开更多

The procedure was followed by a wide decompressive laminectomy. The patient had a progressive improvement of the symptoms which gradually disappeared in 12 mo. The radiograph at 6 and 12 mo showed complete fusion system. The choice of treatment in L5-S1 ontogenetic spondylolithesis is related to a correct clinical and diagnostic planning(X-ray, computer tomography magnetic resonance imaging, Measurement). In particular, the severity index and the square of unstable zone, and the standard measurements already described in the literature, are important to understand and to plane the correct surgical strategy, that require, in most of the times, fusion and interbody artrodesis.展开更多

METHODS We retrospectively reviewed 34 patients with symptomatic lumbar ganglion cysts treated with spinal canal decompression with or without spinal fixation. Microsurgical approach was the main procedure and spinal instrumentation was required only in case of evident preoperative segmental instability. RESULTS The complete cystectomy with histological examination was performed in all cases. All patients presented an improvement of clinical conditions, evaluated by Visual Analogic Scale and Japanese Orthopaedic Association scoring. CONCLUSION Spinal ganglion cysts are generally found in the lumbar spine. The treatment of choice is the microsurgical cystectomy, which generally does not require stabilization.The need for fusion must be carefully evaluated: Preoperative spondylolisthesis or a wide joint resection, during the operation, are the main indications for spinal instrumentation. We propose the terms "ganglion cyst" to finally identify this spinal pathology and for the first time its morphological classification, clinically useful for all specialists.展开更多

Only 6% of chordomas are localized to the cervical level. In young patients, chordomas are rare and unpredictable. Despite this, the treatment of choice remains the total resection, as much as possible, followed by proton beam radiation. This case was managed using a precarotid and retrocarotid approach at the same time. The tumor was completely resected with the edges free from disease. The cervical spine was stabilized with an anterior plating C2-C4. Eighteen months after surgery the patient is still free from illness. Multilevel oblique corpectomies are an available and safe option for the treatment of upper cervical chordomas.展开更多

During later stages of segmental degeneration, kyphosis of the cervical spine can occur and further compromise the spinal cord and nerve roots. Optimal surgical approach remains controversial. The choice to perform an anterior, posterior or combined approach depends on: sagittal alignment, number of involved levels, main compression localization, and clinical status. The anterior approach is recommended when compression involves primarily anterior horn of spinal cord. Methods: between January 2001 and December 2005, 121 patients (42 F, 79 M, mean age 62 years) were operated for cervical spondylosis (98 myelopathy, 23 radiculopathy). Anterior surgical approach was performed in 81 patients. 63 patients were operated performing multilevel discectomy and fusion (ACDF) and 18 patients performing corpectomy and fusion and anterior plating (ACCF). Preoperative documentation collected consisted of cervical X-ray (static-dynamic), cervical spine TC, cervical MRI. Clinical documentation permitted us to obtained clinical status of each patient based on JOA, NDI and VAS. A Clinical and radiological follow-up was performed at 1 month, 3 months, 1 year, 6 years, 12 years. Results: the fusion rate was calculated based on the static and dynamic X-ray (flexion and extension position), only a little percentage of patients underwent CT scan. There were no significant differences between ACDF and ACCF in clinical outcome at 6 years evaluated by VAS and NDI. The rate of fusion at 6 years for 2 levels ACCF (92%) was higher than that for 2 levels ACDF (86%) but is not statistically significative. Conclusion: classifying degenerative disease and biomechanics feature, preoperatively in necessary to guide the surgeon to choose the best anterior approach for cervical spondylosis.展开更多
