DEFINITION When abnormalities of the spine occur, the natural curvatures of the spine are misaligned or exaggerated in certain areas.Of seventy-four children who were treated at a mean age of seventeen months for neuroblastoma and survived more than five years, fifty-six had spinal deformity due either to the disease or to the treatment after a mean follow-up of 12.9 years. For National Scoliosis Awareness Month, we interviewed Bridget of C urvy Girls Scoliosis Foundation to learn more of what it was like to grow up with scoliosis.spine curvature disorders johny wilbert, m.scn lecturer, apollo institute of hospital management and allied science 2. When the spine is viewed from the back, patients with scoliosis have a spinal curvature that looks like a C (one curve) or an S (two curves) when viewed on an x-ray.
Eighteen per cent of 419 children with this malignant disease survived more than five years, and of the survivors, 20 per cent had spinal deformity severe enough to warrant treatment. The deformity was due either to the laminectomy or to the paraplegia acting in conjunction with the radiation. Epidural spread of the neuroblastoma was associated with most of the cases of severe scoliosis and kyphosis. The post-radiation deformity - both the scoliosis and the kyphosis - progressed with growth, the scoliosis at a rate of 1 degree per year and the kyphosis at a rate of 3 degrees per year. Two kyphotic thoracolumbar curve patterns were identified: an angular kyphosis with a short radius of curvature and its apex at the twelfth thoracic and first lumbar vertebrae, and a thoracic kyphosis with more » a long radius of curvature that extended into the lumbar spine.
Again, in all these situations, there are mild cases or severe cases. Kyphosis patients have upper backs that are abnormally rounded. The bottom of the spine curves inward. Lordosis is also known as swayback. « lessThe spine often looks like a C shape or an S shape.
Twenty-two lesions (25.8%) were treated for recurrence after prior radiotherapy (RT). Materials and Methods: Between April 2008 and December 2010, 85 lesions in 66 patients were treated with SBRT for spinal metastases. We report prospective results of this population at Mayo Clinic. Purpose: Based on reports of safety and efficacy, stereotactic body radiotherapy (SBRT) for treatment of malignant spinal tumors was initiated at our institution. Certain health problems can cause curvature of.
In 1 of 2 patients experiencing Grade 3 toxicity, SBRT was given after previous radiation. No cases of Grade 4 toxicity were reported. The median dose delivered to patients who experienced local/marginal failure was 24 Gy (range, 18-30 Gy) in a median of three fractions (range, 1-5). Actuarial local control at 1 year was 83.3% and 91.2% in patients with and without prior RT. A total of 7 patients had both local and marginal failure, 1 patient experienced marginal but not local failure, and 1 patient had local failure only.
« lessCurvature of the Spine. Further research is needed to determine optimum dose and fractionation to further improve local control and prevent toxicity. Our results appear comparable to previous reports analyzing spine SBRT. Toxicity of treatment was rare, including those previously irradiated.
Recent advances in stereotactic IGRT have allowed for spinal applications. Its use for the treatment of spinal lesions has been limited because of the availability of effective target immobilization devices.

More » Lesion location included 92 cervical, 234 thoracic, 130 lumbar, and 86 sacral. Patient ages ranged from 18 to 85 years (mean 56 years). At our institution, we have developed a successful multidisciplinary spinal radiosurgery program in which 542 spinal lesions (486 malignant and 56 benign lesions) were treated with a single-fraction radiosurgery technique.
Three hundred thirty-seven lesions had received prior external beam irradiation with spinal cord doses precluding further conventional irradiation. Tumor volume ranged from 0.16 to 298 mL (mean 47 mL). The maximum intratumoral dose ranged from 12.5 to 30 Gy (mean 20 Gy). Thoracic, lumbar, and sacral tumors were tracked relative to either gold or stainless steel fiducial markers. Eighty-nine cervical lesions were treated using skull tracking. The most common benign tumors were neurofibroma (24 cases), schwannoma (13 cases), and meningioma (7 cases).
The potential benefits of radiosurgical ablation of spinal lesions are short treatment time in an outpatient setting with essentially no recovery time and excellent symptomatic response. Spinal stereotactic radiosurgery is now a feasible, safe, and clinically effective technique for the treatment of a variety of spinal lesions. Thirty of 35 patients (85%) with progressive neurological deficits experienced at least some improvement after treatment. Long-term tumor control was demonstrated in 90% of lesions treated with radiosurgery as a primary treatment modality and in 88% of lesions treated for radiographic tumor progression. Axial and/or radicular pain improved in 300 of 326 cases (92%). Follow-up period was at least 3 to 49 months.
The degree of spinal curvature. Clinical assessment appears insufficient to decide how advanced the disease is and what the treatment results are.
