摘要:

Extreme lateral lumbar disc herniation (ELLDH) occurring into and/or outside the intervertebral foramen was encountered in 95 cases amongst 1600 operations for herniated lumbar disc (6%): 43% occurred at L5-S1, 38% at L4–5, 18% at L3–4, and 1% at L2–3. The incidence amongst all herniations at one particular level was 6% at L5-S1, 4% at L4–5, and 18% at L3–4. The clinical presentation varied according to the level of extreme lateral disc herniation, but was not different from the presentation of a classical paramedian herniation occurring one level above. Forty-three patients were investigated with computed tomography (CT) only, 2 with myelography only, and 50 with both. CT always clearly demonstrated the pathology, but some cases are presented to illustrate the differential diagnosis. Myelography was normal in 13 cases; in 27 cases it showed a typical shortening and enlargement of the nerve root sheath which enters the affected intervertebral foramen. At operation, a total facetectomy was performed in 52 patients, a partial facetectomy in 34, and a lateral approach to the intervertebral foramen in 9. The lateral approaches, either paramuscular with retraction of the paraspinal muscles from the midline, or transmuscular by splitting of the paraspinal muscles, are described and illustrated in detail.

摘要:

A retrospective survey has been carried out of 59 patients who suffered head injury related to horse riding out of 7172 cases of head and spinal injury admitted to a regional head injury unit in the 5-year period 1980–85. Most (85%) were female, against the usual 80% male predominance of head injury, 56 were minor injuries and 3 severe, of whom 2 died. Skull fracture was present in 10 patients (17%) of whom at least 5 had been wearing headgear at impact, and scalp trauma was noted in 22 (37%) with a predominance of occipital injuries. All the severely injured cases had an occipital skull fracture. One fifth of the patients suffered additional significant injuries. While most patients (90%) made a good recovery, 2 remained moderately and one severely disabled. Horse riding posed a significant risk of head injury to the population of riders, mainly young women. This survey suggests that the wearing of amateur riding headgear does not adequately protect the rider from scalp and skull injury, particularly in the occipital region.

摘要:

Two cases of intrathecal disc protrusion and a review of the literature is presented. The rarity of this complication, which might occur after an incomplete disc removal, is pointed out. These two cases confirmed that the L4–5 interspace is the one most commonly affected.

摘要:

We report two patients with acoustic neuromas which spread upwards through the petrous temporal bone into the middle fossa as well as medially through the porus acousticus into the posterior fossa. There appear to be no previous reports of such transpetrous spread of an acoustic neuroma.

摘要:

A case of a 19-year-old man with a right parasellar chondroma examined with computed tomography (CT) and nuclear magnetic resonance (NMR) scan is reported. The literature about CT and NMR scan findings of intracranial chondroma is reviewed. Typical CT findings are a round, high density mass with calcification, that is only slightly enhanced by contrast medium.
