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.

Randomized Controlled Trial
Pre-emptive infiltration of levobupivacaine is superior to at-closure administration in lumbar laminectomy patients.
This is a prospective, randomized, controlled trial that compared the efficacy of different protocols of local tissue infiltration with levobupivacaine or levobupivacaine-methylprednisolone at the surgical site for pain relief after lumbar discectomy. The objective of the study was to determine the efficacy of preemptive wound infiltration with levobupivacaine and levobupivacaine-methylprednisolone at the surgical site for pain relief. Patients usually suffer significant pain after lumbar discectomy. ⋯ The treated groups had lower parenteral opioid requirements after surgery, lower incidences of nausea and shorter hospital stays. Further, the data indicate that, compared with infiltration of these drugs at wound closure, preemptive injection of levobupivacaine or levobupivacaine-methylprednisolone into the muscle near the operative site provides more effective analgesia after lumbar discectomy. Our data suggest that preemptive infiltration of the wound site with levobupivacaine alone or combined with methylprednisolone provides effective pain control with reduced opiate dose after unilateral lumbar discectomy.

Review Case Reports
Symptomatic vertebral hemangioma in pregnancy treated antepartum. A case report with review of literature.
Pregnancy related compressive myelopathy secondary to vertebral hemangioma is a rare occurrence and its treatment antepartum is rare. We report a 22-year-old lady in her 26th-week of pregnancy who was treated in two stages--antepartum with a laminectomy and posterior stabilization. ⋯ This two-staged approach appears safe and effective in treating symptomatic vertebral haemangiomas causing neurological deficits during pregnancy. A review of relevant literature has been done.

Review Case Reports
Sacral fractures after multi-segmental lumbosacral fusion: a series of four cases and systematic review of literature.
Spine surgeons are becoming increasingly aware of sacral insufficiency fractures as a complication after lumbosacral fusions. We present four patients who suffered from sacral fractures after multi-segmental posterior lumbosacral fusion together with a systematic review of the literature that yielded six papers reporting on 12 cases. ⋯ It remains unclear whether this complication is rare or rather under-diagnosed. Fortunately, these fractures are predominantly benign conditions that respond well to conservative management in the majority of cases, depending on location.

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.
