[Therapeutic results in spinal tumor metastases involving neurologic deficit].

Between 1976 and 1982 primary or secondary intraspinal malignant lymphomas and metastases of solid tumours with neurologic defects were found in 118 hospitalised patients. A total of 126 episodes of spinal and caudal compressions were observed. Nearly half of all tumour diagnoses were breast and prostatic carcinomas. Segments Th 3-6 were mainly involved. Symptoms of compression were the first objective hints of malignant disease in every third patient. Local and (or) radicular pains were reported as first symptoms by 80% of patients. Therapeutic success was considered satisfactory (group A) if patients were able to walk freely 3 months after initiation of treatment or isolated loss of sensitivity or defects of urination or defaecation could not be demonstrated any longer. Results were classified as unsatisfactory (group B) if the above-mentioned aims of treatment could not be achieved within this time. After individualised carefully monitored treatment, survival of patients of group A was significantly longer after 12 and 24 months than in patients of group B. Probability of survival is mainly influenced by rapid response to treatment, by tumour histology, by severity of neurologic defects and by the chosen treatment regime.

A new device for internal fixation of thoracolumbar and lumbar spine fractures: the 'fixateur interne'.

A new system of operative fixation of thoracolumbar and lumbar spine fractures is presented: the 'fixateur interne' (F.I.). From a posterior approach long Schanz screws are inserted through the pedicles into the body of the two vertebrae just adjacent to the lesion and connected by th threaded F.I. rods. By tightening the nuts the Schanz screws are fixed in all directions. The advantages of the F.I. system are: excellent reposition by the long lever-arm of the Schanz screws, immobilization of only two segments and therefore good mobility of the residual spine, stability against flexion forces better than is obtained with Harrington distraction rods, additional rotational stability, and fixation in lordosis or kyphosis as is desired. The F.I. does not act as a four point bending system like all other dorsal spine instrumentation systems, but provides stability in flexion by itself. Therefore it can be Used independently of the condition of all ligaments (including the anterior longitudinal ligament) and of the posterior wall of the fractured vertebrae, and there is no need to fix more than the two immediately adjacent vertebrae, thus avoiding the often painful and cumbersome iatrogenic loss of lumbar lordosis and of mobility and permitting early mobilization of the patient. Experience with the first 45 patients is very promising.
