Review Case Reports
Hypoglossal nerve injury as a complication of anterior surgery to the upper cervical spine.
Injury to the hypoglossal nerve is a recognised complication after soft tissue surgery in the upper part of the anterior aspect of the neck, e.g. branchial cyst or carotid body tumour excision. However, this complication has been rarely reported following surgery of the upper cervical spine. We report the case of a 35-year-old woman with tuberculosis of C2-3. ⋯ The hypoglossal palsy persisted, although with minimal functional disability. The only other reported case of hypoglossal lesion after anterior cervical spine surgery in the literature also failed to recover. It is concluded that hypoglossal nerve palsy following anterior cervical spine surgery is unlikely to recover spontaneously and it should be carefully identified.

Somatic and mental symptoms in 22 patients (16 women and 6 men) 22-73 months after a whiplash injury are described. The results of the present study are compared with the corresponding results of a previous study on the same patients. According to the Quebec Classification System, the whiplash injuries of 15 patients were classified as grade 2 and those of 7 patients as grade 3. ⋯ The Mood Adjective Check List was used as a measure of mental well-being. During the 2 years that had passed since the previous study, the patients had improved regarding pain intensity, pain tolerance level and mental well-being. The results show that patients with prolonged disability after a whiplash injury can improve even after a long time.

Review Case Reports
Traumatic L5-S1 spondylolisthesis: report of three cases and a review of the literature.
The literature reports that traumatic spondylolisthesis of L5 is an uncommon lesion. The authors report their experience of three cases of this particular fracture-dislocation of the lumbosacral spine. ⋯ A preoperative MRI study appears mandatory in order to evaluate the integrity of the L5-S1 disc. In the event of a traumatic disruption of the disc, they state the importance of posterior interbody fusion by means of a strut graft carved from the ilium or, in case of iliac wing fracture (which is not uncommon in these patients), by means of interbody cages.

Long-term exposure to whole-body vibration is known to increase the risk of low back problems. The chain of events leading from repeated loading of the lumbar spine to back complaints and the exact nature of the vibration-induced damage are, however, obscure. Fluid in- and outflow as well as viscoelastic deformation are important aspects of the physiological function of the lumbar disc. ⋯ Likewise, MRI examinations revealed no significant differences in the water content of the discs averaged over the lumbar spine. In addition, QCT examinations revealed no significant difference in the trabecular bone density of the third lumbar vertebra. The study thus revealed no significant difference between a cohort with long-term exposure and non-exposed controls with respect to viscoelastic properties of discs as determined by stadiometry, average water content of lumbar discs and trabecular bone density of L3.
