Intra-operative cultures may be obtained in revision spine surgery despite the absence of pre-operative clinical markers of infection. The microbiologic profile of culture positive cases in which there is no clear evidence of infection preoperatively has not been described. The aim of this investigation is to report on the microbiologic profile of unexpected culture positive revision spine surgery cases. ⋯ Nearly one in five patients with the diagnosis of pseudarthrosis were culture positive. More specifically, pseudarthrosis was the most common culture positive diagnosis and P. acnes species predominated in this patient population. Propionibacterium acnes was overwhelmingly the most common single organism cultured in revision spine surgery. Given this, we recommend all cultures be held for P. acnes, particularly in the setting of pseudarthrosis.

Simpson grade II removal (coagulation of the dural attachment after gross total removal) of spinal meningioma is considered an acceptable alternative, but increased recurrence after more than 10 years has been reported. More attention must be paid to the long-term surgical outcomes after Simpson grade II removal. ⋯ Simpson grade II removal may be an alternative option if the risk of complications with Simpson grade I removal is expected to be high.

To highlight cervical spondylodiscitis as an infrequent complication following an invasive procedure on the neopharynx in patients previously treated with circumferential pharyngolaryngectomy with pectoralis major myocutaneous flap reconstruction. ⋯ Cervical spondylodiscitis is a rare but potentially severe complication following an invasive procedure on the neopharynx after circumferential pharyngolaryngectomy. Therefore, the onset of nonspecific symptoms should not be overlooked, and MRI must be performed if infection is suspected. Microbiological confirmation is critical in optimising treatment, which should be aggressive, even if overall prognosis seems to be good.

The aim of this study is to evaluate the incidence of the anatomical anomalies of the V3 segment of the vertebral artery in the Polish population. There is conflicting evidence on the incidence of these anomalies: Asian-based studies show high incidence of 10 %, whereas the North American study identifies these anomalies in less than 1 % of patients. ⋯ Very low incidence of V3 segment anomalies does not justify in our opinion routine vascular imaging in patients undergoing posterior cervical instrumented procedures.

Variability of the human lower lumbar geometry is related to complications of disc arthroplasty surgery. Accurate morphometric descriptions are essential for the design of artificial intervertebral discs to ensure good prothesis-vertebra contact and better load distribution, and can improve spinal biomechanics. Unfortunately, current knowledge of the lower lumbar geometry is limited either in the representativeness of sample populations or the accuracy and comprehensiveness of measurements. The objective of this study was to establish an accurate and reliable measurement protocol, provide a comprehensive database of lower lumbar geometry, and compare and summarize geometric data as reported in the literature. ⋯ This study demonstrates the potential of using MRI data to establish a standard measurement protocol for morphometric quantification of the lower lumbar intervertebral discs and vertebral endplates. These results are invaluable in characterizing comprehensive lower lumbar morphometry, which may provide crucial information for planning spinal surgeries, designing artificial intervertebral discs, and for biomechanical modeling of the low lack.
