In recent years, there has been much debate on the treatment of whiplash-associated disorders (WAD). It is not clear if the treatments commonly employed are effective, and concerns have been raised on the available scientific evidence of many of these treatments. The aim of this study was to review the literature systematically to analyze the evidence basis of many commonly used treatments for patients suffering from WAD, both in the acute and the chronic state. ⋯ Based on the degrees of evidence and the practical obstacles, the following treatments can be recommended: Early physical activity in acute WAD, radiofrequency neurotomy, combination of cognitive behavioral therapy with physical therapy interventions, and coordination exercise therapy in chronic WAD. High-quality RCTs are not common in the field of WAD. More research is needed, particularly on the treatment of chronic WAD.

Purely extradural cavernous hemangiomas of the spinal canal are extremely rare. Their occurrence at the lumbosacral level is a true exception. ⋯ Cavernous hemangioma should be considered in the differential diagnosis of an enhancing extradural periradicular mass causing chronic lumbar radiculopathy especially in fertile women. Lumbar extradural hemangiomas appear and behave differently, not only from intramedullary cavernous hemangiomas but also from extradural hemangiomas of other spinal locations.

Comparative Study
Comparison of conventional versus minimally invasive extraperitoneal approach for anterior lumbar interbody fusion.
The purpose of the study was to compare conventional versus minimally invasive extraperitoneal approach for anterior lumbar interbody fusion (ALIF). Fifty-six consecutive patients with spondylolisthesis, lumbar instability, or failed back syndrome were treated with ALIF between 1991 and 2001. The patients were retrospectively evaluated and divided in two groups: Group 1, consisting 33 patients, was treated with ALIF using the conventional retroperitoneal approach, and Group 2, consisting of 23 patients, was operated with the minimally invasive muscle-splitting approach for ALIF. ⋯ There was no statistical difference in the occurrence of complications with both approaches nor with the fusion rates of 92% in group 1 and 84% in group 2 respectively. The minimally invasive extraperitoneal approach for ALIF was associated with significantly less intraoperative blood loss, operation time, and length of the skin incision. In addition, this approach showed significant improvement in postoperative back pain in comparison to the conventional approach for ALIF.

Comparative Study
A two-cage reconstruction versus a single mega-cage reconstruction for lumbar interbody fusion: an experimental comparison.
Interbody cages are used as an adjunct to anterior lumbar interbody fusion, but exposure and insertion of two cages can be difficult. A biomechanical study was performed to compare the stability and exposed surface for fusion obtained with interbody reconstruction using two traditional cylindrical cages (18-mm diameter) vs. a single expanded mega-cage (24-mm diameter). A single-cage technique could result in safer exposure, shorter operating time, and less cost. ⋯ The stiffness with a single anterior mega-cage was significantly lower in flexion compared with two standard cages. However, in all other modes of testing the constructs were statistically equivalent, although neither construct was significantly stiffer than the intact specimen. Additionally, the single mega-cage provides an equivalent cancellous bed for fusion as compared to dual cages. While this study is not sufficient to recommend human application, these results and our previous experience with the successful in vivo use of a single cage in rhesus monkeys [4] suggest that the single expanded anterior cage may be an acceptable concept although subsidence risk needs further investigation. The potential advantages of a single mega-cage (safer for the foramen, safer for the vessels, more consistent decortication and possibly cheaper) further suggest that examination should be given to this method as an approach to anterior interbody reconstruction in selected patients.

The aim of this study was to define the influence of whiplash injuries on the perceived condition of health 3 years after injury. We evaluated remaining symptoms and the use of health services. Insurance companies provided reports and medical certificates from traffic accidents in Finland in 1998, for those injured who had agreed to take part in the study. ⋯ Although some of the injured had improved in the long term, some reported that their health condition was worse after 3 years than at the 1-year follow-up. The percentage of respondents reporting a significant health deterioration remains unchanged 3 years after the whiplash injury. These findings illuminate the importance of early recognition of risk factors for long-term disability and the primary treatment and rehabilitation procedures.
