Possible negative impact of polypharmacy on surgical outcomes in older patients with lumbar spinal stenosis.

Aim: Older patients with lumbar spinal stenosis (LSS) have a higher incidence of polypharmacy attributed to comorbidities and the use of pain relief medications. This study aimed to explore the effect of polypharmacy and hyperpolypharmacy on surgical outcomes in older patients with LSS based on health-related quality of life (HRQOL) and locomotive syndrome.

Methods: Consecutive patients aged ≥65 years who underwent lumbar spinal surgery for LSS were retrospectively reviewed.

Relationship between frailty and locomotive syndrome in older patients with degenerative cervical myelopathy: A retrospective longitudinal study.

Background: The management of degenerative cervical myelopathy (DCM), which often impairs lower extremity function and increases the risk of falls, is gaining recognition for its importance in an aging society. Despite the significant overlap between frailty and locomotive syndrome (LS) in older adults, their interaction in older DCM patients remains unclear. We aimed to determine the characteristics of older DCM patients with frailty, focusing on the association between frailty and LS.

Elucidation of the Mechanism of Occasional Anterior Longitudinal Ligament Rupture with Posterior Correction Procedure for Adult Spinal Deformity Using LLIF-Finite Element Analysis of the Impact of the Lordotic Angle of Intervertebral LLIF Cage.

There are several advantages of using lateral lumbar interbody fusion (LLIF) for correction surgeries for adult spinal deformity (ASD); however, we currently have unresolved new issues, including occasional anterior longitudinal ligament (ALL) rupture during the posterior correction procedure. When LLIF was initially introduced, only less lordotic cages were available and ALL rupture was more frequently experienced compared with later periods when more lordotic cages were available. We performed finite element analysis (FEA) regarding the mechanism of ALL rupture during a posterior correction procedure.

Impact of Lumbar Surgery on Pharmacological Treatment for Patients with Lumbar Spinal Canal Stenosis: A Single-Center Retrospective Study.

Treatment for lumbar spinal canal stenosis (LSCS) is mainly classified into conservative and surgical therapies. Among conservative therapies, pharmacological treatment is commonly prescribed for LSCS. Meanwhile, surgical treatment is the last option for LSCS.
