Neuropathy of the saphenous nerve as a cause of knee pain.

Neuropathy of the infrapatellar branch of the saphenous nerve is a frequently overlooked cause of persistent medical knee pain. The author wishes to identify this as a distinct entity and to present five cases. All of these cases were caused by direct blows to the medial aspect of the knee, did not respond to conservative treatment, and were essentially cured via neurolysis or neurectomy of the infrapatellar branch. Nerve entrapment is a frequent cause of intractable symptomatology in various areas of the body. The most commonly recognized nerve entrapment condition is carpal tunnel syndrome. Another condition, saphenous nerve entrapment, is all too frequently overlooked and underdiagnosed.

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.

Fracture of a vertebral body end plate and disk protrusion causing subarachnoid block in an adolescent.

An apparently unique case of retroprotrusion of a portion of the vertebral end plate plus L4 disk in a 16-year-old boy demonstrated a complete myelographic block. The block was produced by a large fragment of bone which had broken off the inferior end plate of the body of L4 and was protruding into the spinal canal. Removal of the bony block and protruding disk resulted in complete resolution of symptoms.
