Relationship between number of radiological risk factors for delayed union after osteoporotic vertebral fracture and clinical outcomes.

Unlabelled: This study demonstrated that number of three specific radiological risk factors (MR T2WI confined high-intensity pattern and diffuse low-intensity pattern, thoracolumbar vertebrae involvement, middle column injury) added prognostic information for delayed union, kyphotic deformity, and prolonged pain.

Purpose: Delayed union after osteoporotic vertebral fracture (OVF) causes prolonged pain, QOL impairment, progression of collapse, kyphotic deformity, and neurologic impairment. Some specific radiological findings can be useful for predicting delayed union.

Impact of paravertebral muscle in thoracolumbar and lower lumbar regions on outcomes following osteoporotic vertebral fracture: a multicenter cohort study.

Unlabelled: We investigated the effect of paravertebral muscle (PVM) on poor prognosis in osteoporotic vertebral fracture (OVF) and remaining lower back pain (LBP) in the thoracolumbar and lower lumbar regions. Additional OVF occurrence in the thoracolumbar and remaining LBP in the lumbar region was significantly related to PVM fat infiltration percentage.

Purpose: Paravertebral muscle (PVM) is an important component of the spinal column.

Characteristic radiological findings for revision surgery after balloon kyphoplasty.

Balloon kyphoplasty (BKP) sometimes fails to improve patients' outcomes, with revision surgery, using anterior or posterior reconstruction, being required. The purpose of this study was to investigate the radiological risk factors of failure after BKP in the treatment of osteoporotic vertebral fractures (OVFs). This case-control study included 105 patients treated with single BKP and 14 patients  who required revision BKP.

Development of a scoring system for predicting adjacent vertebral fracture after balloon kyphoplasty.

Background Context: The incidence of adjacent vertebral fracture (AVFs) is reported to be 10%-38% after balloon kyphoplasty. However, no reports have established a system for prediction of AVF occurrence.

Purpose: To establish a scoring system for predicting AVF occurrence after balloon kyphoplasty for osteoporotic vertebral fractures (OVFs).

Association between MRI findings and back pain after osteoporotic vertebral fractures: a multicenter prospective cohort study.

Background Context: Osteoprotic vertebral fractures (OVFs) are common in elderly people. The association between back pain due to OVF with magnetic resonance imaging (MRI) signal change is unclear. In this study we hypothesized that MRI findings would be a predictive factor for back pain measured by visual analogue scale (VAS) at 6 months follow-up.

Cost-effectiveness of Balloon Kyphoplasty for Patients With Acute/Subacute Osteoporotic Vertebral Fractures in the Super-Aging Japanese Society.

Study Design: A propensity score matching study.

Objective: The aim of this study was to assess the cost-effectiveness of balloon kyphoplasty (BKP) in Japan.

Summary Of Background Data: Osteoporotic vertebral fracture (OVF) is a common disease in elderly people.

Balloon Kyphoplasty Versus Conservative Treatment for Acute Osteoporotic Vertebral Fractures With Poor Prognostic Factors: Propensity Score Matched Analysis Using Data From Two Prospective Multicenter Studies.

Study Design: A multicenter, prospective, single-arm, intervention study.

Objective: The aim of this study was to investigate efficacy of balloon kyphoplasty (BKP) for acute osteoporotic vertebral fractures (OVFs) in patients with poor prognostic factors.

Summary Of Background Data: The indications for BKP remain unclear.

The degeneration of adjacent intervertebral discs negatively influence union rate of osteoporotic vertebral fracture: A multicenter cohort study.

Background: With the increasing aging population in developed countries, there has been an associated increased prevalence of osteoporotic vertebral fracture (OVF). Many previous reports have attempted to predict the risk of delayed union associated with OVF. However, the role of endplate failure and the degeneration of adjacent intervertebral discs, and their association with delayed union has received little attention.

Characterizing the course of back pain after osteoporotic vertebral fracture: a hierarchical cluster analysis of a prospective cohort study.

Unlabelled: This study demonstrated four distinct patterns in the course of back pain after osteoporotic vertebral fracture (OVF). Greater angular instability in the first 6 months after the baseline was one factor affecting back pain after OVF.

Purpose: Understanding the natural course of symptomatic acute OVF is important in deciding the optimal treatment strategy.

New Predictive Index for Lumbar Paraspinal Muscle Degeneration Associated With Aging.

Study Design: A cross-sectional imaging study of paraspinal muscle degeneration using a new index for easy evaluation.

Objective: To examine the natural progression of age-related changes in the lumbar paraspinal muscles and to verify the validity of our new index for evaluating paraspinal muscle degenerationSUMMARY OF BACKGROUND DATA.: Measurement of paraspinal muscle morphology is an effective method for reflecting atrophy and fat infiltration, but it is complicated to perform.

Lamina horizontalization and facet tropism as the risk factors for adjacent segment degeneration after PLIF.

Study Design: A retrospective case-control study.

Objective: To clarify associations between both lamina horizontalization and facet tropism and adjacent segment degeneration (ASD).

Summary Of Background Data: We have previously reported coexistence of lamina horizontalization and facet tropism adjacent to the cranial fusion segment as risk factors for ASD.

Repair of cervical esophageal perforation using longus colli muscle flap: a case report of a patient with cervical spinal cord injury.

Background Context: Perforation of the esophagus after anterior cervical spine surgery is a rare, but well-recognized complication. The management of esophageal perforation is controversial, and either nonoperative or operative treatment can be selected.

Purpose: Several reports have described the use of a sternocleidomastoid muscle flap for esophageal repair.
