We investigated the prognosis of low-back pain and the association of clinical symptoms and anatomic findings among young athletes. Consecutive patients, aged between 12 and 18 years, who had low-back pain that had interfered with their training for at least 4 weeks were included in the case series. All the patients participated in a standardized interview and clinical examination, and plain radiographs and magnetic resonance images were also obtained. ⋯ In conclusion, the reasons for prolonged back pain among young athletes are usually established by imaging studies. A knowledge of anatomic abnormalities may help in tailoring training programmes and avoiding the progression of changes during growth. Simple restriction of painful activities usually leads to good recovery.

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.

Whilst neurologic injury following correction of scoliosis with CD-instrumentation is generally known to be an early complication, any late occurrence of cauda compression secondary to employment of a laminar hook-rod construct is exceptional. We report on such a rare case of late occurrence of cauda equina syndrome, when a laminar hook at level L2 became symptomatic causing compression of the cauda equina almost a decade after spine surgery. This case demonstrates that one should not only be aware of a potential neural injury at intraoperative placement of laminar hooks, but also one is reminded that a laminar hook poses the threat of late neurologic injury years after successful osseous spinal fusion. The surgeon treating patients with scoliosis must be aware of the possible complication described in our patient in addition to those that have already been well documented.

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.
