Percutaneous posterior instrumentation followed by direct lateral interbody fusion for lumbar infectious spondylitis.
Retrospective study. ⋯ Minimally invasive PPI followed by debridement and DLIF was a feasible surgical alternative in our consecutive 16 cases of pyogenic spondylitis. In most cases, however the subsidence of anteriorly grafted fusion was inevitable despite successful fusion and eradication of the primary lesion.

Mid-term follow-up of clinical and radiologic outcomes in cervical total disk replacement (Mobi-C): incidence of heterotopic ossification and risk factors.
Cervical arthroplasty has been shown to have successful, short-term and long-term radiologic and clinical outcomes. The incidence of and predisposing factors for heterotopic ossification (HO) have not been determined. We retrospectively assessed the intermediate-term clinical and radiologic outcomes, especially the incidence of HO and its risk factors. ⋯ Intermediate follow-up of cervical arthroplasty showed good clinical outcomes, although there was a trend toward reduction in alignment and motion at 24 months. The overall HO occurrence was 94.1% at 24 months. In our study, the most important factor affecting HO was the different surgical techniques.

Usefulness of MRI in determining the appropriate level of cement augmentation for acute osteoporotic vertebral compression fractures.
This is a prospective study on consecutive patients with acute osteoporotic vertebral compression fractures (OVCFs). ⋯ MRI with STIR sequencing exhibited a multitude of benefits in the exact identification of acute lesions and hidden lesions. Because of the high rate of misdiagnosis using standard plain radiographs and CT scans of the spine for OVCFs, MRI with STIR sequencing should be considered before cement augmentation procedures. Moreover, in cases with multiple lesions or severe osteoporosis, the importance of MRI should be further emphasized.
