Dynamic study of the lumbar intervertebral joints disc lesions

Dynamic motion of the lumbar spine in different root syndromes due to disc lesion was studied both preoperatively and postoperatively. The study was carried on 131 cases. The cases were studied roentgenologically in full flexion and extension, and the range of movement at each ventral level. The results were compared with a normal control group. The study showed that the normal range of the lumbar spine is around 60 degrees and that 1.4/5 range of motion shore in the movement by about 25% of total movement. In patients with low back pain and different lumbar and sacral root syndromes, the range of motion falls to around half the normal. It also proved that the limitation of movement did not improve by surgery and bilateral facetectomis had significantly low results

Tumours of the brain stem A clinical, radiologial and operative study

Twenty-five patients with brain stem glioma were studied clinically, radiologically and their management was discussed. When a clinical diagnosis of brain stem glioma made all ancillary diagnostic tests should be used to verify the lesion. It makes little difference what the histological type is, since all lesions in this region should be considered malignant because of their anatomical location. They cannot be removed surgically and it is generally believed that few patients will be cured with radiotherapy. It should be stressed that they usually respond to high voltage therapy, which relieves many of the unpleasant symptoms, markedly improves the quality of life and in rare instances may produce a prolonged survival. The recent refinements in diagnostic techniques have increased the value of air studies and in almost every case the correct diagnosis is reached by this method of investigation
