Different operative possibilities for treatment of lumbar disc herniations--how to choose the best method for the individual patient.

The indications for operative treatment of lumbar disc herniations are outlined and the advantages, short-comings and temptations of discolysis, micro-operation and large approach discussed. The following indication scheme is proposed: Discolysis: Non-displaced disc herniation without other major causative pathology; Micro-operation: Displaced disc herniation; non-displaced disc herniation with monosegmental additional causative factors; Large approach: Multiple disc herniations with suspected displacement and multisegmental additional pathologies.

Chymopapain↗

[Extreme lateral lumbar intervertebral disk displacement. Incidence, symptoms and therapy].

Upper lumbar nerve root compression or a femoralgia is often caused by extreme lateral lumbar disc herniation. This type of lumbar disc herniation compresses the nerve root inside or laterally to the intervertebral canal, while mediolateral disc herniations squeeze it in the lateral recess. Pain radiating obliquely over the thigh is the dominant clinical symptom. Bending the body to the ipsilateral side usually increases the pain. When neurologic signs are present, motor deficits tend to be more prominent than sensory and the deficits never affect more than one nerve root. Most frequently a weakness of knee extension occurs.

[Segmental instability and lumbar spinal canal stenosis. Theoretical, clinical and surgical aspects].

Clinical, radiological, surgical and experimental observations make it possible to construct a rational theory of the segmental lumbar instability which explains the pathogenesis of spondylosis, of stenosis and of several cases of disc displacement as well. This theory helps us to choose the right surgical procedure. Spinal stenosis, degenerative spondylolisthesis and some cases of disc displacement are seen as part of a degenerative process with its starting point in regressive changes of the intervertebral disc and lateral joint. This leads to a marked instability of the affected mobile segment. Signs and symptoms of unstable lumbar spine are discussed. In such cases, if decompression of the roots by laminectomy, facetectomy or discectomy is performed without fusion, the consequences are usually treated but not the main cause of the trouble, namely the instability. Finally, we describe a procedure which we prefer as the safest and best of all, using selected decompression by means of joint screws (spondylodesis) as suggested by F. Magerl (41-44).

[Thoracic intervertebral disk displacement: a rare differential diagnosis of segmental irritation--guidelines for use of chiropractic therapy].

Thoracic disc herniations rarely occur; they vary with respect to the clinical symptomatic and do not always lead to neurological deficit. A patient is being reported on with first symptoms of unspecific back pain. The patient has been frequently treated within 12 months (at regular intervals) exclusively by chiropractic manipulation without a considerable success. It is the objective of this case report that in persistent and therapy resistant back pain without obvious neurological deficite beside native radiographs further diagnostic investigation (MRI) is indicated. Concerning chiropractic manipulations (mobilisation techniques with impulse) this paper recommends testing maneuvers, the consideration of contraindications (structural lesions, neurological deficite) and emphasizes the use of atraumatic manipulation techniques.

[Exertion, spinal fracture, intervertebral disk displacement].

If causes which cannot be clearly defined as traumatic, result in vertebral fractures or disc ruptures, the expert frequently finds himself confronted with considerable problems. He must carefully establish the relation between what is due to the trauma and what must be attributed to the pre-existing damage. This requires the pre-existing nox to be objectively cleared, especially with regard to osteoporosis. The diagnosis "osteoporosis" should be subjected to particularly careful investigation, especially if the patient is a male. X-ray photographs, taken at an early stage, are insufficient. As consequences for the patient might be heavy, intensive methods of examination are justified. Anamnesis, progress and effect must be critically weighted, exceptions from the rule must be founded on careful and logical reasoning. The above article deals with such an exception.
