We present a sternoclavicular dislocation as a non-reported complication after spinal kyphotic deformity surgical correction. ⋯ Sternoclavicular dislocation after spine kyphotic deformity correction is presented for the first time; however, it is not possible to establish a causative association. Additional studies are necessary to delineate the role of the sternoclavicular complex in Scheuermann's disease.

The American Society of Anaesthesiologists' Physical Status Score (ASA) is a key variable in predictor models of surgical outcome and "appropriate use criteria". However, at the time when such tools are being used in decision-making, the ASA rating is typically unknown. We evaluated whether the ASA class could be predicted statistically from Charlson Comorbidy Index (CCI) scores and simple demographic variables. ⋯ It was possible to predict ASA from CCI. In a simple model, CCI ≥ 1 best distinguished between ASA ≥ 3 and < 3. For a more precise prediction, regression algorithms were created based on CCI and simple demographic variables obtainable from patient interview. The availability of such algorithms may widen the utility of decision aids that rely on the ASA, where the latter is not readily available.

Dislocation is one of the remaining challenges after total hip arthroplasty. The spinopelvic mobility is considered to be the key to solve this problem and is of interest both to arthroplasty and spine surgeons. The purpose of this letter is to discuss the spinopelvic mobility and spinal stiffness described in the paper titled "Impact of spinal alignment and stiffness on impingement after total hip arthroplasty: a radiographic study of pre‑ and post‑operative spinopelvic alignment." by Hagiwara S, et al. METHODS: Examining the consistency between this paper and previously published papers on spinopelvic mobility. ⋯ The conclusions and titles are overstated from the results, but this paper is highly valuable in reminding spinal surgeons of the importance of spinopelvic alignment and mobility in THA.

Some atypical vertebral hemangiomas (VHs) may mimic metastases on routine MRI and can result in misdiagnosis and ultimately to additional imaging, biopsy and unnecessary costs. The purpose of this study is to assess the utility of intravoxel incoherent motion (IVIM) diffusion-weighted imaging (DWI) on account of field-of-view optimized and constrained undistorted single shot (FOCUS) in distinguishing atypical VHs and vertebral metastases. ⋯ The standard ADC value and D value may be used as an indicator to distinguish vertebral metastases from atypical VHs. FOCUS IVIM-derived parameters provide potential value in the quantitatively differentiating vertebral metastases from vertebral atypical hemangiomas.
