This prospective demographic study was undertaken to review the epidemiology and demographics of all acute admissions to the National Spinal Injuries Unit in Ireland for the 5 years to 2003. The study was conducted at the National Spinal Injuries Unit, Mater Miscericordiae University Hospital, Dublin, Ireland. Records of all patients admitted to our unit from 1999 to 2003 were compiled from a prospective computerized spinal database. ⋯ The cervical spine was most commonly affected (51%), followed by lumbar (28%) and thoracic (21%). On admission 38% of patients were ASIA D or worse, of which one-third were AISA A. Understanding of the demographics of spinal column injuries in unique populations can help us to develop preventative and treatment strategies at both national and international levels.

Case Reports
Intradural extramedullary primary hydatid cyst of the spine in a child: a very rare presentation.
Spinal hydatid cyst is a serious but fortunately uncommon manifestation of the parasite Echinococcus, involving less than 1% patients with hydatid disease. Intradural hydatid cysts are extremely rare compared to other types of spinal hydatid cysts. We report a rare case of intradural, extramedullary spinal hydatid cyst in a 9-year-old male boy, who presented with weakness of both lower limbs for the last 4 months that was confirmed histopathologically; a better understanding of this rare but clinically challenging disease is intended by reporting this case.

The objective of the study was to evaluate the breathing pattern in patients with chronic non-specific low back pain (LBP) and in healthy subjects, both at rest and during motor control tests. Ten healthy subjects and ten patients with chronic LBP participated at this case-control study. The breathing pattern was evaluated at rest (standing and supine position during both relaxed breathing and deep breathing) and while performing clinical motor control tests, i.e. bent knee fall out and active straight leg raise. ⋯ At rest, no significant differences were found between the breathing pattern of patients and healthy subjects (P > 0.05). In contrast, significantly more altered breathing patterns were observed in chronic LBP-patients during motor control tests (P = 0.01). Changes in breathing pattern during motor control tests were not related to pain severity (P > 0.01), but were related to motor control dysfunction (P = 0.01).

Pertinent literature exists concerning indications, techniques, complications of treatment, and risk factors for nonunion in axis and odontoid fractures; however, there are scarce data regarding the incidence and definition of malunion in these fractures. As a prerequisite for the study of anatomical alignment following surgical and nonsurgical treatment of C2-fractures, an understanding of normal C2 anatomy is essential. Therefore, the authors intended to evaluate morphometrical dimensions of the C2 vertebra. ⋯ The measurement process resulted in 2,400 data points. Distinct morphometrical parameters, such as a quantitative characterization of the sagittal atlantoaxial congruency, the lateral mass inclination and the type of degenerative changes at the atlantoaxial joint could be demonstrated to be valuable and reliably used within a proposed classification for C2-malunions following C2-fractures. The current study offers a template including recommended radiological measurements for further research on the study of clinical outcome and posttraumatic alignment following C2-fractures.

Multicenter Study Clinical Trial
Intermediate clinical and radiological results of cervical TDR (Mobi-C) with up to 2 years of follow-up.
The interest in cervical total disc replacement (TDR) as an alternative to the so-far gold standard in the surgical treatment of degenerative disc disease (DDD), e.g anterior cervical discectomy and fusion (ACDF), is growing very rapidly. Many authors have established the fact that ACDF may result in progressive degeneration in adjacent segments. On the contrary, but still theoretically, preservation of motion with TDR at the surgically treated level may potentially reduce the occurrence of adjacent-level degeneration (ALD). ⋯ Finally, after 2 years, 91% of the patients assume that they would undergo the procedure again. These intermediate results of TDR with Mobi-C are very encouraging and seem to confirm the efficacy and the safety of the device. Regarding the preservation of the status of the adjacent levels, the results of this unconstrained device are encouraging, but longer FU studies are needed to prove it.
