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.

Sex Differences in Postoperative Complications and Functional Status After Deformity Correction Surgery: Do Men Fare Better Than Women?
We investigated whether a sex-related difference exists in the postoperative complication risk and health-related quality of life measures after surgery for adult spinal deformity. ⋯ In the present study, after adjustment for important baseline prognostic factors, no differences were found in the postoperative complication rates or extent of functional improvement when stratified by sex. Both sexes responded equally well to corrective surgery for symptomatic adult spinal deformity.

Asymptomatic or minor symptom meningiomas (AMSMs) in the elderly are incidental findings, with no consensus reached on the optimal management strategy. In the present study, we aimed to determine the surgical risk factors for elderly patients with AMSMs using a nationwide registry database in Japan. ⋯ For elderly patients with surgically treated AMSMs, advanced age was a prominent risk factor for functional decline at discharge. Our study identified several factors that should be evaluated before proceeding with surgery for AMSMs in elderly and pre-elderly patients. These findings could, not only improve decision-making among clinicians treating patients with AMSMs, but also help in predicting the results of surgery for elderly patients with AMSMs.

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.
