Compression of the upper cervical spinal cord due to stenosis of the b
ony spinal canal is infrequent. In the first case reported here, steno
sis was due to acquired extensive, unilateral osteophytes centered on
the left apophyseal joints of C1-C2 in an elderly professional violini
st. In the second case, stenosis was secondary to isolated congenital
hypertrophy of the laminae of C1 and C2.
