In children, high rates of occipitocervical (OC) fusion have been demonstrated with the use of rigid instrumentation in combination with harvested autograft, with or without bone morphogenetic protein (BMP). Historically, the use of allograft materials demonstrated inferior OC fusion outcomes compared with autograft. However, autograft harvest harbors an increased risk of patient morbidity, and the use of BMP is costly and controversial in children. Thus, there remains a need for safer, less costly, yet efficacious techniques for OC fusion in the pediatric population. ⋯ We demonstrate a modified technique for OC fusion in children with unique structural allograft shaping and affixation, leading to excellent fusion outcomes at follow up. This technique obviates the need for autograft harvest or BMP, and may decrease postoperative morbidity.

Spondylodiscitis is a rare inflammatory syndrome affecting intervertebral discs and adjacent vertebral bodies. Without appropriate therapy, serious complications, such as secondary spinal epidural abscess (SEA), may prolong recovery time. In this study, we compared the main characteristics of our cohort of patients with spondylodiscitis with those of patients reported in the international literature and analyzed the impact of complications associated with spondylodiscitis on clinical outcomes. ⋯ The clinical characteristics of our study cohort did not differ from the international trends. Primary, noncomplicated spondylodiscitis has the highest odds for absolute recovery. Secondary spinal epidural abscess exacerbates ongoing spondylodiscitis, and thus should be considered a poor prognostic factor for spondylodiscitis. Early diagnosis and treatment may prevent serious complications and provide better outcomes.

IgG4-Related Disease: A New Etiology Underlying Diffuse Intracranial Dilating Vasculopathy.
Diffuse intracranial aneurysmal vasculopathy is a rare condition, previously described in patients with human immunodeficiency virus infection. IgG4-related disease (IgG4-RD) is a recognized inflammatory disease of systemic organs, leading to fibrosis of connective tissues. It also has been linked to inflammatory dilating aortic aneurysms, coronary vascular disease, hypophysitis, orbital pseudotumor, and pachymeningitis. It has not yet been described as a cause of diffuse intracranial dilating vasculopathy. Histologically, this disease is characterized by IgG4-plasma cell infiltration, fibrosis, and phlebitis. ⋯ This is the first reported case of a diffuse intracranial dilating vasculopathy secondary to IgG4-RD. Recognition of similar pathologic findings in clinical presentation and radiologic workup should prompt further rheumatologic workup and possible immunosuppressive therapies.

Is there a place for the posterior approach in cases of acute myelopathy on thoracic disc hernia?
Acute myelopathy in cases of thoracic disc herniation (TDH) is an exceptional condition for which the treatment is not codified. Here we present the results of a standardized procedure in 10 patients who underwent surgery for acute myelopathy on TDH between December 2009 and December 2016. ⋯ Laminectomy appears to allow stabilization of the neurologic situation in rare cases of acute myelopathy on TDH. The need for complementary resection of the hernia by an anterior approach should always be discussed secondarily.

Injury to the brachial plexus is a devastating condition, with severe impairment of upper extremity function resulting in distinct disability. There are no systematic reports on epidemiology, causative mechanisms, treatment strategies. or outcomes of iatrogenic brachial plexus injury (iBPI). ⋯ Most common causes for iBPI were shoulder surgery and resection or biopsy of peripheral nerve sheath tumor and lymph nodes. Early referral to specialized peripheral nerve centers may help to improve functional patient outcome.
