Spino-pelvic parameters and back pain in patients without coronal deformity or history of spinal surgery: A cross-sectional analysis.

Background: During the last two decades, there has been a growing interest in spinal sagittal alignment. Most published studies have focused on the role of spinopelvic parameters in patients with adult spinal deformity or in those with previous spinal fusion.

Objective: The aim of this study was to explore possible association between disability related to back pain and spinopelvic parameters in the absence of coronal deformity or previous spinal surgery.

Long-term safety and clinical performance of kyphoplasty and SpineJack® procedures in the treatment of osteoporotic vertebral compression fractures: a pilot, monocentric, investigator-initiated study.

Unlabelled: This pilot monocenter study in 30 patients with painful osteoporotic vertebral compression fractures compared two vertebral augmentation procedures. Over a 3-year post-surgery follow-up, pain/disability/quality of life remained significantly improved with both balloon kyphoplasty and SpineJack® techniques, but the latter allowed better vertebral body height restoration/kyphosis correction.

Introduction: Patient follow-up rarely exceed 2 years in trials comparing vertebral augmentation procedures for the treatment of painful osteoporotic vertebral compression fractures (VCFs).

Heterotopic Ossification in Cervical Disk Surgery Is Still a Problem. What Are the Key Factors for a Solution?

Background: The aim of our study was to determine the presence of heterotopic ossifications (HO) in a series of patients with cervical disk arthroplasty treated with different type of prosthesis, as well as to analyze the most suitable systems for diagnosis.

Methods: A retrospective study of patients with cervical disk disease treated with cervical arthroplasty between May 2005 and December 2009, was performed. Patients were divided into 3 groups, depending on the prosthesis implanted: (Group A: Baguera prosthesis, Group B: ProDisc prosthesis, and Group C: PCM prosthesis).

Long-Term Benefits of Percutaneous Anatomical Restoration of Vertebral Compression Fractures Linked to Malignancy.

Aim: To evaluate the efficacy, feasibility and safety of a percutaneous anatomical vertebral body reduction for the treatment of VCF (vertebral compression fracture) linked to malignancy. Vertebroplasty and percutaneous kyphoplasty have played essential roles in the treatment of painful vertebral metastasis, although there are few reports with long survival that have evaluated the long-term efficacy, adjacent fractures and vertebral body (VB) re-collapse associated with these procedures. We aimed to evaluate the longterm efficacy and the complications associated with malignancy and changes in spinal biomechanics.
