The purpose of this study is to examine whether there are relations between different types of pain in groups of patients with different diagnoses of degenerative diseases of the spinal column and their related surgeries.

In the context of this work the pain of different groups of patients should be examined by means of the painDetect Questionnaire, the Roland-Morris disability questionnaire, clinical examinations and different imaging procedures. Two groups of patients are compared with each other. Group one consists of patients with osteoporotic fractures of the vertebra. Group two is formed by patients with osteochondria , spinal disc herniation and nerval compression. Both groups of patients undergo surgery, as they are suffering from pain (e.g. kyphoplasty, nucleotomy, spondylodesis, decompression). In order to differentiate between chronic nociceptive pain and chronic neuropathic pain in these two groups the painDetect questionnaire is used. To examine the severity of disability in the patients' everyday life the Roland-Morris Disability questionnaire is used.

The included patients are examined and seen preoperative, postoperative before discharge from hospital, 6 weeks and 6 months after surgery.
