Selective Temporary Stent-Assisted Coil Embolization for Intracranial Wide-Necked Small Aneurysms Using Solitaire AB Retrievable Stent.

Objective: Stent-assisted coil embolization of intracranial wide-necked aneurysm requires long-term postoperative antiplatelet therapy to prevent in-stent thrombosis. This study aimed to demonstrate results of temporary stent placement for coiling wide necked small intracranial aneurysms, which eliminated need for antiplatelet agents, and to discuss its feasibility and safety.

Methods: Data of 156 patients who underwent stent-assisted coil embolization between 2011 and 2014 were retrospectively analyzed.

Therapeutic efficacy of injectable calcium phosphate cement in osteoporotic vertebral compression fractures: prospective nonrandomized controlled study at 6-month follow-up.

Background: Alternative biocompatible filler materials replacing polymethylmethacrylate (PMMA) cement have been introduced and clinically tested. Callos calcium phosphate cement (CPC) is one of them. A prospective nonrandomized controlled study was performed to assess the clinical and radiologic results after balloon kyphoplasty with Callos CPC in osteoporotic vertebral compression fractures.

Prognostic factors related to motion dynamics following cervical arthroplasty with a bryan disc: average 2-year follow-up.

Background: This is a retrospective study to assess the prognostic factors influencing the postoperative motion dynamics and clinical outcome following cervical arthroplasty with a Bryan disc.

Methods: Twenty-seven patients (30 levels) consecutively underwent cervical arthroplasty using a Bryan disc (Medtronic Sofamor Danek, Memphis, Tennessee). Motion dynamics and clinical outcome (visual analogue score (VAS) and neck disability index (NDI) score) were examined preoperatively and at 1 month, 1 year, and final follow-up (average: 25 months).
