Critical Evaluation of the Scientific Literature Concerning Bone Graft Alternatives in Spinal Surgery and Focus on Bioceramics.

To improve solid spinal fusion while avoiding the morbidity associated with autograft harvesting procedures, numerous alternatives have been investigated, including allograft, demineralized bone matrix (DBM), cell-based therapies and growth factors (i.e., bone morphogenetic proteins, platelet concentrates), and ceramic-based biomaterials.

Acute neurologic decline in a patient with spinal stenosis: blame it on the epidural fat.

Spinal epidural lipomatosis [SEL] is defined as an excessive accumulation of extradural normal adipose tissue. This condition may be idiopathic or acquired. Surgical decompression is considered the gold standard treatment in patients presenting with progressive neurologic deficit.

Giant tuberculoma of the corpus callosum, the unforeseen diagnosis.

Objective: Isolated intracranial tuberculomas are rare, especially in adults and it is not uncommon that they are easily confused with other diseases. To address this issue, we reported a case of a tuberculoma of the corpus callosum focusing on clinical characteristics, diagnostic clues, and outcome.

Conclusions: Intracranial masses are frequently targeted as neoplastic pathology with surgical treatment in most cases.

Internal carotid artery dissection related to abnormalities of styloid process: is it only a matter of length?

Introduction: Vascular Eagle syndrome, due to impingement of the extracranial internal carotid artery (ICA) by the styloid process (SP), is an uncommon and not yet widely recognized cause of ICA dissection. Up to now, this diagnosis is still presumptive, based mainly on the length of the SP. However, given the discrepancy between the much higher prevalence of an elongated SP in the population compared to the reported rate of Eagle syndrome, other anatomical factors beyond the length itself of this bony structure seem to be involved.

Midline lumbar fusion with cortical bone trajectory as first line treatment in a selected series of patients with lumbar instability.

Background: The aim of the present study was to proof that for certain complex spinal conditions, midline lumbar fusion (MIDLF) technique is very convenient in terms of length of hospitalization, functional recovery and pain relief and time to back to work.

Methods: MIDLF indications were set for patients with not more than 3 unstable levels, presence of osteoporosis (alternative to cemented screws), or cardiomyopathy with anticoagulation with or without spinal stenosis, and or discopathy. Surgical difficulties, operative time, hemoglobin loss and postoperative 45 days, 6 months and one-year follow-up data are shown.
