Objective:
The present study compared the clinical functional outcomes and new vertebral compression fractures (NVCFs) between percutaneous vertebroplasty (PVP) and conservative treatment (CT) in patients with severe pain due to acute osteoporotic vertebral compression fractures (OVCFs). PVP has been increasingly used for the treatment of pain in patients with OVCFs. However, the effectiveness of the procedure and whether it causes NVCFs has remained controversial.
Methods:
A total of 544 eligible patients with OVCFs found on spinal radiographs and intractable back pain for ≤6 weeks were recruited from September 2012 to February 2018 and assigned to PVP (n = 280; 392 levels) or CT (n = 264; 366 levels). The visual analog scale and Oswestry Disability Index scores were determined before the intervention and at the 1-week and 1-, 3-, 6-, 12-, and 24-month follow-up examinations. In addition, monthly telephone follow-up interviews were performed. In the case of a sudden increase in back pain, the patient returned to the hospital for medical and magnetic resonance imaging examinations for NVCF detection.
Results:
The PVP group had significantly lower visual analog scale and Oswestry Disability Index scores than those for the CT group at 1 week and 1, 3, and 6 months (P < 0.05). However, the differences after 6 months were not statistically significant (P > 0.05). Similar numbers of NVCFs (total and adjacent fractures) were found at 24 months in both groups (P > 0.05).
Conclusions:
Compared with CT, PVP provided a rapid decrease in pain and an early return to daily life activities, without an increase in the incidence of NVCFs.

Superficial Layer:
The superficial layer consists primarily of the splenius muscles, which include the splenius capitis and splenius cervicis. These muscles are mainly responsible for the head and cervical spine movements, including extension, rotation, and lateral bending. The splenius capitis...

Regions of the Vertebral Column
In an adult, the spine is subdivided into five regions: the cervical, the thoracic, the lumbar, the sacral, and the coccygeal region. The spine initially develops as a series of 33 vertebrae; after 20 years of age, the nine bones in the sacral region, five sacral, and four coccygeal bones fuse to form...
01:27Fractures: Bone Repair
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the...
