Review Case Reports
Spinal cord herniation into pseudomeningocele after traumatic nerve root avulsion: case report and review of the literature.
We present an extremely rare case of traumatic spinal cord herniation due to a brachial plexus avulsion injury and provide a review of the literature of spinal cord herniation. Spinal cord herniation is an uncommon condition that can occur spontaneously or as a result of surgery or trauma. This condition often presents with symptoms and signs as Brown-Séquard syndrome. ⋯ The patient underwent primary closure of pseudomeningocele to prevent spinal cord reherniation. He can walk with cane and use left arm unrestrictedly at the 2-year follow-up examination. Spinal cord herniation following traumatic nerve root avulsion is extremely rare but it should be considered in the differential diagnosis of patients presenting with delayed myelopathy or Brown-Séquard syndrome.

Review Case Reports
Chronic recurrent multifocal osteomyelitis presenting as acute scoliosis: a case report and review of literature.
Chronic relapsing multifocal osteomyelitis (CRMO) is a rare condition. It commonly affects the clavicle and pelvis. Rarely it can affect the spine. ⋯ Prognosis is generally good although the disease can relapse and remit over many years. At 9 months follow up, the lesions were resolving and the deformity had resolved. CRMO presenting as acute scoliosis is rare and to our knowledge this is the second recognised case in the reported world literature.

Case Reports
Discrepancies of MRI findings between recumbent and upright positions in atlantoaxial lesion. Report of two cases.
Two cases of atlantoaxial (A-A) instability that showed different MRI findings between supine and upright positions are presented. The upright MRI represented the findings corresponding to their symptoms. In A-A lesions, conventional MR images taken in the supine position do not always explain the pathophysiological consequences. The MR images taken in the upright position disclose the actual spinal pathophysiology with gravitational effects.

Persons with recurrent low back pain (LBP) have been observed to have altered proprioceptive postural control. These patients seem to adopt a body and trunk stiffening strategy and rely more on ankle proprioception to control their posture during quiet upright standing. The aim of this study is to determine the effect of changing postural condition (stable and unstable support surface) on postural stability and proprioceptive postural control strategy in persons with recurrent LBP. ⋯ Persons with recurrent LBP showed significantly different postural control strategies favoring ankle muscle proprioceptive control (ratio closer to 1) instead of paraspinal muscle proprioceptive control (ratio closer to 0) for both standing without foam (ratio ankle muscle/paraspinal muscle control = 0.83) (P < 0.0001) and on foam (ratio ankle muscle/paraspinal muscle control = 0.87; P < 0.0001) compared to healthy individuals (0.67 and 0.46, respectively). It is concluded that young persons with recurrent LBP seem to use the same proprioceptive postural control strategy even in conditions when this ankle strategy is not the most appropriate such as standing on an unstable support surface. The adopted proprioceptive postural control strategy might be effective in simple conditions, however, when used in all postural conditions this could be a mechanism to undue spinal loading, pain and recurrences.

Vascular injury as a complication of disc surgery was first reported in 1945 by Linton and White. It is a rare but potentially fatal complication. ⋯ Treatment has traditionally been by open vascular surgical repair, however with modern imaging and endovascular techniques, minimally invasive treatment should be considered first line in patients who are stable. We present the case of a 51-year-old woman who sustained common iliac artery injury during lumbar spinal surgery that was treated successfully using a covered stent.
