A 7 1/2-month-old boy had an anterior inferior dislocation of the shoulder. Dislocations of the shoulder in infants have previously been reported, and were either congenital dislocations with associated anomalies of the glenohumeral joint with dislocations from Erb's palsy or septic arthritis. In the present case, dislocation of the shoulder was associated with spastic brain damage. The marked spasticity of the deltoid muscle may have been the deforming force. Capsular and subscapularis plication plus recession of the deltoid corrected the deformity and prevented further dislocations.

Although it was first described over a century ago (by Charcot in 1865; by Erb in 1875), the concept of primary lateral sclerosis (PLS) is still not universally accepted. Despite this skepticism, several well-documented cases of isolated degeneration with varying degrees of involvement of corticospinal pyramidal pathways have been reported in the literature. The clinical manifestations in these cases can take one of two forms, ie, isolated spasmodic paraplegia or tetraplegia on the one hand or spasmodic tetraplegia associated with a pseudobulbar syndrome featuring severe spastic dysarthria (chronic progressive bilateral spinobulbar spasticity) on the other hand. Obviously, without firm pathologic data, PLS is a hazardous diagnosis for isolated paraplegia or tetraplegia. Conversely, for bilateral spinobulbar spasticity, it would appear to be the only diagnosis possible once investigate findings have eliminated the other possibilities, such as a pyramidal form of amyotrophic lateral sclerosis or a spinal form of multiple sclerosis. To underscore this point, in this report, five cases of chronic progressive bilateral spinobulbar spasticity developed over 5, 10, 12, 10, and 28 years, respectively, for which the only possible diagnosis was PLS. It was concluded that there are three forms of degenerative diseases of the principal motor pathways: one involving both central and peripheral neurons, ie, amyotrophic lateral sclerosis; one involving only peripheral neurons, ie, spinal amyotrophy; and one involving only central motor neurons, ie, PLS.

The relationship between the interruption of the human pyramidal tract and its attendant clinical manifestations has been a matter of concern to neurologists and neurosurgeons for over a century. We presently report three cases of unilateral pyramidal tract ischemic lesions within the cerebral hemispheres who presented with a contralateral pure spastic hemiplegia syndrome. In none could we find any disturbance in the somatosensitive evoked potentials of the four limbs. The review of some cases on record since the time of Charcot and Erb has made it clear that the pyramidal syndrome is a valid clinical concept which should be qualified according to the particular animal species one is referring to. In man, it manifests itself by paresis, hyperactive muscular reflexes, spasticity and Babinski sign. Based on this evidence we propose the idea of a "differential control" exerted by the pyramidal tract upon the segmental neuronal pool as its key mode of normal functioning.
