| diskectomy | Excision, in part or whole, of an intervertebral disk. The most common indication is disk displacement or herniation.

| diskectomy, percutaneous | Percutaneous excision of a herniated or displaced intervertebral disk by posterolateral approach, always remaining outside the spinal canal. Percutaneous nucleotomy was first described by hijikata in japan in 1975. In 1985 onik introduced automated percutaneous nucleotomy which consists in percutaneous aspiration of the nucleus pulposus. It is carried out under local anaesthesia, thus reducing the surgical insult and requiring brief hospitalization, often performed on an outpatient basis. It appears to be a well-tolerated alternative to surgical diskectomy and chymopapain nucleolysis. (12 Dec 1998) |

Dislike, Aversion, Reluctance, Repugnance, Disgust, Antipathy. Dislike is the more general term, applicable to both persons and things and arising either from feeling or judgment. It may mean little more than want of positive liking, but antipathy, repugnance, disgust, and aversion are more intense phases of dislike. Aversion denotes a fixed and habitual dislike, as, an aversion to or for business. Reluctance and repugnance denote a mental strife or hostility something proposed (repugnance being the stronger), as, a reluctance to make the necessary sacrifices, and a repugnance to the submission required. Disgust is repugnance either of taste or moral feeling, as, a disgust at gross exhibitions of selfishness. Antipathy is primarily an instinctive feeling of dislike of a thing, such as most persons feel for a snake. When used figuratively, it denotes a correspondent dislike for certain persons, modes of acting, etc. Men have an aversion to what breaks in upon their habits, a reluctance and repugnance to what crosses their will, a disgust at what offends their sensibilities, and are often governed by antipathies for which they can give no good reason.
