[Backache from the internal medicine-rheumatologic viewpoint].

In only 30% of back pain patients an underlying pathology can be found. Rheumatologic causes in a narrow sense are fibromyalgia, osteoporosis and the group of spondylathropathies and reactive arthritis. Infectious disorders of the spine are emergency cases and need immediate and interdisciplinary action. Careful evaluation of signs and symptoms indicate the suspected origin of pain and lead to the use of more specialized diagnostic means. Therapy of specific back pain should be appropriate to the clinical disorders. In acute, nonspecific back pain, the aim is to prevent a chronification of disease by instruction and education of the patient and an early start of physical therapy. The rehabilitation process in chronic cases in complex and may need psychobehavioral methods for pain control. Pharmacologic modalities of treatment-simple analgesics, nonsteroidal antirheumatic drugs, muscle relaxants and antidepressants-should only be used for a limited period and monitored constantly.
