Our study's aim is to evaluate prospectively the efficacy of ozone nucleolysis in the treatment of either contained or uncontained lumbar disc herniations. METHODS: Fifty-two patients, aged 27-87 years, with symptomatic herniated lumbar discs, without migration, sequestration, or severe degenerative disc changes, who failed conservative treatment, were ...

Anterior Cervical Reconstruction Using Free Vascularized Fibular Graft after Cervical Corpectomy
Study Design Prospective study. Objective The aim of this study was to evaluate the clinical and radiologic results of using free vascularized fibular graft (FVFG) for anterior reconstruction of the cervical spine following with varying levels of corpectomy. Methods Ten patients underwent anterior cervical reconstruction using an FVFG after cervical corpectomy augmented with internal instrumentation. All patients were evaluated neurologically ...

Oncological Principles for Excision of Primary Spinal Tumors.
Enneking examined the mechanism of local spread of primary bone and soft tissue tumors of the extremities and proposed the concept of compartmentalization and anatomic barrier. Based on this concept, he classified t surgical margins of tumor excisions into intracapsular, marginal, wide, and radical. A radical margin means that the lesion and the compartment (s) which it involved have been ... Read more

Comment on Effect of timing of pulmonary metastases identification on prognosis of patients with osteosarcoma: the Japanese Musculoskeletal Oncology Group study.
In our article, we investigated the clinical course of patients with osteosarcoma after the patients develop lung metastasis, dividing the patients into four groups, depending on timing of identification of lung metastases.1 Few data exist on the literature about the effect of relapse of pulmonary metastatic disease from osteosarcoma on patient survival.2 Unfortunately, Professor Briccoli did not report the total ...

Management of Osteoporotic Spine Fractures: Controversy Continues.
Vertebral compression fractures due to osteoporotic disease represent an increasingly significant public health problem [1]. There is no sharp line demarcation between stages of the fracture; acute, subacute and chronic. Lines of treatment include conservative treatment (e.g. brace and pain killers), cement augmentation (vertebroplasty, kyphoplasty and stentoplasty) and surgical treatment. Treatment remains an area of controversy with respect to best ... Read more

Surgical Treatment of Lumbar Spine Infections by Posterior Lumbar Interbody Fusion  with Anterior Reconstruction by Spinal Shortening
In severe osteomyelitis of the spine, open debridement and anterior fusion by anterior bone grafting offers the advantage of eradication of the focus of infection and improvement of conditions for bony fusion of the affected vertebral bodies. Some limited papers reported the use of spinal shortening for anterior reconstruction after fractures or tumors. Ten patients of infections of the thoracic ... Read more

Total en bloc spondylectomy for spinal metastases in thyroid carcinoma.
Thyroid carcinoma generally has a favorable prognosis, and patients rarely present with distant metastases. Authors of several studies have proposed piecemeal resection for spinal metastases in thyroid carcinoma; however, few have analyzed the impact of local curative surgery such as total en bloc spondylectomy (TES) for thyroid carcinoma. The purposes of the present study are to determine the strategy of ... Read more
