Multicenter Study Observational Study
Low implant failure rate of percutaneous fixation for spinal metastases: A multi-center retrospective study.
To evaluate incidence and types of implant failure observed in a series of patients with spinal metastases (SM) treated with minimally invasive stabilization surgery without fusion. ⋯ A low implant failure rate was observed over the short and medium term, even when short instrumentations without fusion were performed. These findings suggest that minimally invasive stabilization surgery without fusion may be an effective and safe way to treat complicated SM.

Revision surgery rates after minimally invasive adult spinal deformity surgery: is there a correlation with Roussouly type at 2-year follow up?
Spinopelvic parameters have hitherto dictated much of adult spinal deformity (ASD) correction. The Roussouly classification is used for the normal adult spine. We evaluated whether a correlation would be found between the Roussouly type and the rate of revision surgery in patients with ASD undergoing circumferential minimally invasive spinal (cMIS) correction. ⋯ We did not find a clear correlation between Roussouly type and the rate of revision surgery for adjacent segment disease or proximal junctional kyphosis in patients who had undergone cMIS surgery for ASD.

Lower back pain associated with degenerative disc disease (DDD) is a leading cause of disability worldwide. Anterior lumbar interbody fusion (ALIF) has been shown to be effective for treating refractory DDD, but it remains unclear which patients may benefit most from the procedure. This study aims to develop a predictive model for clinical success in L5/S1 ALIF for DDD. ⋯ This analysis confirms workers' compensation and low preoperative ODI as risk factors for successful L5/S1 ALIF performed for DDD. It also identifies novel prognostic factors, namely posterior disc height and disc depth. This model can aid in patient counseling and selection in the management of L5/S1 DDD.

Coagulation Profile as a Significant Risk Factor for Short-Term Complications and Mortality Following Anterior Cervical Discectomy and Fusion.
Cervical degenerative disc disease is the most common indication for anterior cervical discectomy and fusion. Given the possible complications, patients are stratified before anterior cervical discectomy and fusion by preoperative risk factors to optimize treatment. One preoperative factor is a patient's coagulation profile. ⋯ Our results show significant differences in the incidence rates of a multitude of complications among the 5 groups based on univariate analysis. Patients with any abnormal coagulation disorder had increased rates of developing any complication or having an extended length of hospital stay.

Intracranial aneurysms (IAs) can be treated through endovascular treatment (EVT) or microsurgery (MS). Treated IAs can recanalize, which can lead to rupture or retreatment. ⋯ The rate of IA retreatment is low; however, the rate of hemorrhage/rupture from treated IAs is even lower. A higher rate of retreatment was noted in EVT-treated IAs versus MS-treated IAs and in ruptured IAs versus unruptured IAs; however, the rate of hemorrhage or rerupture was comparable between the groups.
