Vertebrogenic pain localised in the anterior thorax can imitate anginal pain ("pseudoangina pectoris"). The most common causes of vertebrogenic chest pain are segmental dysfunction and degenerative changes at the level of the lower cervical and upper middle thoracic spine. Segmental dysfunction is a source of pseudoradicular pain, and degenerative changes, before all disc hernia and dorsal osteophytes which are compressing corresponding nerve roots, are the sources of radicular pain which irradiates in the chest. Because of its similarity with angina pectoris, the intense chest pain caused by the cervical radiculopathy which is often followed by heart rhythm disorders and nonspecific changes of the ST-T-segment in ECG, is called "cervicogenic angina". The attacks of vertebrogenic chest pain are not rare even in patients with angina pectoris. Because of superimposed vertebrogenic pain, the manifestation of pain in patients with angina pectoris can be considerably changed which can be misinterpreted as unstable angina. From therapeutic aspect it is very important to distinguish vertebrogenic from anginal pain. That is, the change of cardiological therapy will not eliminate possible attacks of vertebrogenic pain in patients with angina pectoris. From the aspect of most recent understandings, the article describes etiopathogenesis, characteristics, diagnosis and therapy of vertebrogenic chest pain, and also the differences between vertebrogenic and anginal pain.

In this study we attempted to explore the correlation between lumbar disc herniation and functional disorders of the lumbar spine. Fifty patients with lumbar disc herniation proven by computed tomography underwent a comprehensive functional, neurological and radiological examination. All patients were compared to a control group consisting of 16 healthy subjects of comparable age. Only patients without signs of bone or soft tissue alterations or pregnancy at the time of examination were included into the study. Herniations of the L4-5 disc showed a dysfunction in the same segment in 64% of the cases. There was also a correlation between this segmental dysfunction and pain in the sacrotuberal and iliolumbar ligaments. All patients with segmental dysfunction felt pain in the dorsal ligaments. If there was no segmental dysfunction pain in the dorsal ligaments was encountered just as often as in the control group. Herniations of the L5-S1 disc had a dysfunction in the same segment in only 12% of the cases, but in 35% there was dysfunction of the L4-5 motion segment. In this group pain in the dorsal ligaments did not correlate with segmental movements. Frequency of ligamental pain in L4-5 herniations was equal to that in L5-S1 herniations. With increasing size of the disc herniation, the frequency of segmental dysfunction, paralysis and loss of reflexes also increased, but the pain in the dorsal ligament decreased.Segmental dysfunction is explained by increased muscular tone being provoked by irritation of the sinuvertebral nerve. The differences between L4-5 and L5-S1 movements are probably due to the different functional anatomy of these segments. Ligamental pain may be explained by the fact that these ligaments have the same insertion and the muscles have increased in tone.
