PURPOSE Standardized indications for treatment of tumor-related spinal instability are hampered by the lack of a valid and reliable classification system. [] Key Method On two occasions at least 6 weeks apart, each rater also scored each patient using SINS. Each total score was converted into a three-category data field, with 0 to 6 as stable, 7 to 12 as potentially unstable, and 13 to 18 as unstable.

Reliability of the spinal instability neoplastic scale among radiologists: an assessment of instability secondary to spinal metastases.

SINS is a reliable tool for radiologists rating tumor-related spinal instability and accurately discriminates between stable and potentially unstable or unstable lesions and, therefore, can guide the need for surgical consultation.

Spine Instability Neoplastic Score: agreement across different medical and surgical specialties.

The Spine Instability Neoplastic Score: an independent reliability and reproducibility analysis.

Agreement in the assessment of metastatic spine disease using scoring systems.

Spinal Instability Neoplastic Score (SINS): Reliability Among Spine Fellows and Resident Physicians in Orthopedic Surgery and Neurosurgery

The SINS is a reliable and valuable educational tool for spine fellows and residents learning to judge spinal instability and its role as an educational tool is determined.

Is the Spinal Instability Neoplastic Score Accurate and Reliable in Predicting Vertebral Compression Fractures for Spinal Metastasis? A Systematic Review and Qualitative Analysis

The SINS system may be accurate and reliable in predicting the occurrence of post-radiotherapy VCFs for spinal metastasis, but some components seem to be substantially weak and need to be revised.

Classifications in Brief: The Spinal Instability Neoplastic Score.

Difficulty diagnosing spinal instability can lead to inappropriate referrals of patients without instability or undertreatment of patients with instability, which highlights the need for a classification system to facilitate communication and to help identify which lesions are unstable and may benefit from evaluation by a spine surgeon.



A Novel Classification System for Spinal Instability in Neoplastic Disease: An Evidence-Based Approach and Expert Consensus From the Spine Oncology Study Group

The Spine Instability Neoplastic Score is a comprehensive classification system with content validity that can guide clinicians in identifying when patients with neoplastic disease of the spine may benefit from surgical consultation and aid surgeons in assessing the key components of spinal instability due to neoplasia.

Instability and impending instability of the thoracolumbar spine in patients with spinal metastases: a systematic review.

Metastatic disease commonly occurs in the spine and incidence is likely to increase secondary to improved survival rates in many cancer patients. Despite published research on instability in patients

Metastatic Disease in Long Bones A Proposed Scoring System for Diagnosing Impending Pathologic Fractures

A weighted scoring system is proposed to quantify the risk of sustaining a pathologic fracture through a metastatic lesion in a long bone and it is suggested that all metastatic lesions in long bones be evaluated prior to irradiation.

Risk factors and probability of vertebral body collapse in metastases of the thoracic and lumbar spine.

There is a distinct discrepancy between the timing and occurrence of vertebral collapse in the thoracic and thoracolumbar or lumbar spine and the optimum timing and method of treatment should be selected according to the level and extent of the metastatic vertebral involvement.

An evaluation of spinal deformity in metastatic breast cancer.

Understanding the natural history of metastatic spinal deformity, instability and spinal canal compromise can be recognized and treated early, before the onset of progressive deformity and neurologic sequelae.

Metastatic Disease of the Spine

New data documenting the benefit of surgical decompression using improved techniques such as anterior approaches have amplified the role of the spine surgeon in the care of these patients.

Impact of Surgical Intervention on Quality of Life in Patients With Spinal Metastases

Surgery for patients with spinal metastases offers decreased pain and improved quality of life with low rates of surgical complications, and the overall risks and benefits of surgical intervention are assessed.

Reconstructive Spinal Surgery as Palliation for Metastatic Malignancies of the Spine

It is considered that prophylactic stabilization of the spine is analogous to prophially nailing of a femur with a pathologic lesion, both the femur and spine are weight-bearing structures and the advent of segmental instrumentation makes this a feasible accomplishment with minimal morbidity.

Percutaneous vertebroplasty and kyphoplasty for painful vertebral body fractures in cancer patients.

Transthoracic vertebrectomy for metastatic spinal tumors.

It is suggested that transthoracic vertebrectomy and spinal stabilization can improve the quality of life considerably in cancer patients with spinal metastasis by restoring or preserving ambulation and by controlling intractable spinal pain with acceptable rates of morbidity and mortality.
