Chronic functional instability is a residual problem after acute ankle sprain. Reasons may be weak ligaments and/or a deficit in the proprioceptive system. Studies have shown that peroneal reaction time (PRT) can be used to quantify proprioceptive performance. ⋯ It was found that PRT is not influenced by extrinsic or anthropometric data. Furthermore, the results prove a significant slackening in PRT with increasing age. Therefore, the patient's age must to be considered in judging the PRT.

Cervical spine changed by Bechterew's disease is severely endangered with any increased load. Even decent trauma is enough to produce a fracture with affection of spinal cord. Because of little knowledge in these special items, late diagnosis of overlooked injury is not rare, especially in two-level injuries. ⋯ There were four patients, that would not have suffered cervical spine fracture (minimal injury force) without Bechterew's changes. There is often pulmonary failure through limitation of thoracic movement and cerebral ischemia following rupture of vertebral arteries as typical complications. Mortality (2 cases; 16%) in our collective is less than literature's medium rates (35-57%).

The complex pathophysiology of electrical injury is caused by several mechanisms which are superimposed and cumulative in action. Existing empirical guidelines are only partially compatible with the results of recent studies. The significance of the joule effect, theories about progressive tissue necrosis, and the traditional surgical approach should be reviewed in view of electroporation and anatomical arrangements. The quality of long-term treatment results and the consistently high rate of amputations have prompted the development of alternative surgical options.

Comparative Study
[Diagnostic value of conventional roentgen image, computerized and magnetic resonance tomography in acute sprains of the foot. A prospective clinical study].
In order to gain satisfying results in the treatment of acute hyperflexion trauma to the foot, it is absolutely necessary to achieve an exact primary diagnosis because injuries to the tarsometatarsal joint are frequently missed primarily. Aim of this prospective clinical study was to evaluate the diagnostic reliability of conventional radiography, CT and MRI compared to each other. 75 consecutive patients after hyperflexion trauma to the foot were included. There were 47 males and 28 females with a mean age of 38 years. ⋯ Additionally, partial or complete tears of Lisfranc's ligament were depicted in 22 patients. The present study could clearly show the superiority of CT and MRI to conventional radiography in diagnosis of bony and ligamentous disorders of the Lisfranc joint. Therefore, extended diagnosis has to be demanded in all cases of hyperflexion trauma to the foot.
