Btween 1971 and 1978 140 cases of spinal metastasis treated by decompression or possible removal of secondary neoplasm, were studied. Patients were divided according to their preoperative neurological conditions and then evaluated on the ground of regression of spinal cord and root symptom. The possibility of treating this type of compressive spinal pathology surgically is discussed.
The authors report on a case of persistent meralgia paraesthetica of the left side, following a weight loss of 8 kg in one month. Not only volumetric changes of the panniculus adiposus in the inguinal region but also a slight arrangement of the inguinal ligament and a state of undernourishment contribute to the compression of the lateral femoral cutaneous nerve. By microsurgical epineurectomy and interfascicular neurolysis the disappearance of the meralgia and preservation of the sensation on the antero-lateral aspect of the thigh are obtained.
A case of Empty Sella secondary to Rathke's cleft cyst, successfully operated on, is reported. Asymptomatic cysts of Rathke's pouch are fairly frequent autopsy observations. They can cause optic-chiasmatic and endocrine symptomatology or, very rarely, an Empty Sella syndrome if the cyst is very large.
The Authors report on nine cases of thoracic disc hernia operated on through Carson's posterolateral approach. Several steps were taken to protect the spinal cord, and to remove completely disc fragments and any calcifications. The importance of the combined use of the operating microscope and the posterolateral approach are emphasized, and the longterm results are evaluated.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
