The dorsal approach is increasingly preferred in the surgical treatment of vertebral fractures. However, the access and the implant's position cause muscle loss, which can lead to instability and a reduced capacity for rehabilitation. Morphological factors (bones, intervertebral discs) are typically blamed for chronic pain syndromes in the literature, while less importance is attached to functional factors (muscles). ⋯ The muscle damage which was established in the multifidus muscle is compensated by increased activity in the iliocostal muscle. On the basis of anatomical considerations, the damage pattern can be identified as having been caused by surgery. It is extremely unlikely that trauma is the cause.

We report a case of rotatory atlantoaxial dislocation due to a rugby injury in an adult. The patient presented with torticollis 4 weeks after the injury. The neurological evaluation was normal. ⋯ After 6 weeks of immobilization in a Minerva jacket, a dynamic rotatory computed tomography (CT) scan confirmed that the atlantoaxial joint was stable. Such cases of atlantoaxial joint dislocation in adults treated by traction after a considerable delay are rare. In our patient, demonstration by MRI that the transverse ligament was intact led to the decision to use conservative therapy, which proved successful.

A review of the literature was conducted to study the pathomechanics by which Paget's Disease of bone (PD) alters the spinal structures that result in distinct spinal pathologic entities such as pagetic spinal arthritis, spinal stenosis, and other pathologies, and to assess the best treatment options and available drugs. The spine is the second most commonly affected site with PD. About one-third of patients with spinal involvement exhibit symptoms of clinical stenosis. ⋯ Five classes of drugs are available for the treatment of PD: bisphosphonates, calcitonins, mithramycin (plicamycin), gallium nitrate, and ipriflavone. Bisphosphonates are the most popular, and several forms have been investigated, but only the following forms have been approved for clinical use: disodium etidronate, clodronate, aledronate, risedronate, neridronate, pamidronate, tiludronate, ibadronate, aminohydroxylbutylidene bisphosphonate, olpadronate, and zoledronate. Several of these forms are still under investigation.

Randomized Controlled Trial Comparative Study Clinical Trial
The use of plate fixation in anterior surgery of the degenerative cervical spine: a comparative prospective clinical study.
The method of anterior mono- or bisegmental cervical spine fusion is a well-established procedure for degenerative conditions of the cervical spine. While the early reports promote fusion with bone graft alone, recent studies report superior results with the addition of anterior plating. The objective of this study was to evaluate the influence of using plates in anterior cervical spine fusion in a prospective study. ⋯ There was no significant difference between the groups for fusion rating, but graft quality (graft height) was significantly better in the plated group. We conclude that the overall data do not suggest better results with plating in mono- or bisegmental anterior spine fusions. Indications for additional internal fixation are restricted to special conditions with increased instability, insufficient bone quality or inappropriate graft placing.
