Lateral interbody fusion and posterior percutaneous pedicle screw (LIF-PPS) fixation has been performed in two-stage positioning. The aim of this study was to investigate the surgical outcomes of simultaneous single-position LIF-PPS fixation using O-arm-based navigation. ⋯ Single-position surgery exhibited comparable clinical outcomes and local lordosis acquisition with conventional repositioning LIF-PPS fixation. This single-position minimally invasive technique reduces the occupancy time of the operating room and workforce requirements. These slides can be retrieved under Electronic Supplementary Material.

Injury to the cervical spinal cord has been suggested as a mechanism that may underpin chronic whiplash-associated disorder (WAD). This study aimed to assess metabolite concentrations indicative of neuronal injury or pathology in the cervical cord in people with chronic WAD. ⋯ Findings are consistent with major metabolic changes not being present in chronic WAD.

The present consensus suggests urgent surgical decompression if clinical features of cauda equina syndrome (CES) are supported by MRI evidence of pressure on cauda equina. However, clinical diagnosis has a high false-positive rate and MRI is a poor indicator. Though urodynamic studies (UDS) provide objective information about the lower urinary tract symptoms experienced by patients including neurogenic bladder, its role in the diagnosis of CES is not established. ⋯ Multichannel UDS provides an objective diagnostic tool to definitively establish the neurovesical involvement in CES. Utilising multichannel UDS as an adjunct to clinical findings avoids the probability of false-positive diagnosis of CES. These slides can be retrieved under Electronic Supplementary Material.

Both increased sagittal vertical axis (SVA) and sarcopenia affect performance of daily activities and morbidity in the elderly; however, little is known regarding their relationship. The aim of this study was to analyze the association between sarcopenia and increased SVA. ⋯ Sarcopenia and fatty degeneration of paraspinal muscle are closely related to increased SVA in the elderly.

Predictors of long-term opioid usage in TLIF patients have not been previously explored in the literature. We examined the effect of pre-operative narcotic use in addition to other predictors of the pattern and duration of post-operative narcotic usage. ⋯ Pre-operative opioid usage is associated with higher total inpatient opioid use and a significantly higher risk of long-term opiate usage at 6 months. Approximately 40% of pre-operative narcotic users will continue to consume narcotics at 6-month follow-up, compared with 5% of narcotic-naïve patients.
