Background and purpose — A significant number of patients with spinal metastases are treated non-surgically, but may need surgical treatment at a later stage due to progression of symptoms. Therefore, we investigated the need for late surgical decompression in patients with spinal metastasis who were initially deemed as non-surgical candidates, as well as the outcome of late surgery. Patients and methods — 116 patients who were referred to the orthopedic oncology department between 2002 and 2011 due to spinal metastasis with neurologic symptoms were deemed to be non-surgical candidates. The primary reason was minor neurologic deficits in 40 patients (M) and short survival (S) in 76 patients. Results — 8 patients underwent a late operation due to progression of the neurologic symptoms, all of them belonged to group M. M-patients with a modified Bauer score of less than 2 had both an inferior survival as well as a higher risk for late surgery. Postoperative improvement in neurologic function was noted in 5/8 operated patients, whilst 2 patients had stationary symptoms and 1 deteriorated. Interpretation — The need for late surgery arises in a minority of patients with spinal metastasis primarily treated non-surgically, and only in patients with minor neurologic compromise rather than poor general condition. An established prognostic score (modified Bauer) can be used to guide decision-making. Late surgical decompression is effective in restoring the neurologic status
