Article Synopsis
- - The study investigates mechanical complications (MCs) in patients with Adult Spinal Deformity (ASD) who are considered well-aligned post-surgery, revealing that alignment alone does not eliminate the risk of these complications.
- - A total of 83 patients aged 55 and older were analyzed, with 40% experiencing at least one MC during an average of 4 years of follow-up, including issues like proximal junctional kyphosis and nonunion of surgical rods.
- - The research utilized a multicenter database to identify and analyze risk factors contributing to MCs through statistical methods like binary logistic regression and ROC curve analysis.
Study Design: Retrospective analysis of a prospective multicenter Adult Spinal Deformity (ASD) registry.
Objective: Assess whether spinal alignment deteriorates post-surgery in absence of mechanical complications and evaluate the long-term outcomes of ASD surgery over a five-year period.
Summary Of Background Data: ASD is prevalent among older adults, leading to significant pain and disability.
Background: The long-term impact of reoperations following adult spinal deformity (ASD) surgery is still poorly understood. Our aim was to identify the relationship between unplanned reoperation and health-related quality of life (HRQoL) gain at 2 and 5 years of follow-up.
Methods: We included patients enrolled in a prospective ASD database who underwent surgery ≥5 years prior to the start of the study and who had 2 years of follow-up data.
Study Design: Translation and psychometric testing of a questionnaire.
Objective: Translation, adaptation, and validation of the Japanese Orthopaedic Association Cervical Myelopathy Evaluation Questionnaire (JOACMEQ) to the Spanish language.
Summary Of Background Data: Degenerative cervical myelopathy (DCM) has a clear impact on quality of life (QoL).
Purpose: To find the cut-off values in the Myelopathy Disability Index (MDI) that will allow us to classify the severity of Degenerative Cervical Myelopathy (DCM) into mild, moderate and severe.
Methods: Cross-sectional study with prospective data collection, with a total of 64 patients diagnosed with Degenerative Cervical Myelopathy (DCM). Anthropometric, diagnostic, neurological, functional and quality of life variables were collected.
Lipomas are the most frequent soft tissue tumors. Osteolipomas are a rare variant that can be difficult to diagnose. We report the case of a 66-year-old man consulting with a tumor of 2 years development in the right paravertebral cervical region.

Material And Methods: A database of 263 patients undergoing lumbar surgery for degenerative conditions was collected. There were 74 patients who were 65 years old or above and 189 who were below 65 who had complete preoperative and 2-year postoperative HRQOL data measures: ODI, SF-36 and COMI.
