The facet joint and its role in spine pain. Management with facet joint injections.

Mechanical derangements of the lumbar spine, causing predominantly back pain with the absence of nerve root irritation or compromise, present a difficult treatment challenge to the average physician. The author suggests that facet joint injections offer a simple, safe, and often dramatically effective means for managing these problems. The historic background and technique are described in detail. The author presents his personal experience with 99 patients receiving a total of 117 facet joint injections in this retrospective, uncontrolled review. Results were classified as excellent in 17%, good in 25%, fair in 9%, mediocre in 4%, and no change in symptoms occurred in 44%. The procedure is recommended for diagnostic and conservative therapy.
