Objective:
This study is to assess an innovative technique - a vertebral osteotome (VO) combined with side-opening injection cannula for percutaneous vertebroplasty (PVP).
Methods:
A retrospective study by propensity score matching. From January 2016 to April 2016, 63 patients who were diagnosed with monosegmental osteoporotic vertebral compression fracture received the innovative technique. The epidemiologic data, surgical indexes, and recovery outcomes were collected in the follow-up period. Propensity score matching identified 63 pairs form historical controls by traditional unilateral PVP approach in 2015 using six independent variables: age, sex, preoperative visual analog score (VAS), Oswestry Disability Index (ODI), body mass index, and bone mineral density.
Results:
The surgical duration and cement distribution were longer and larger in patients by VO method. Besides, postoperative VAS and ODI in the VO group were lower than those in the control group. However, there were no differences in radiation exposure times, improvement of Cobb angle, cement leakage, or adjacent vertebral fracture between two groups. Cement volume in the VO group was less than that in the control group.
Conclusion:
This new innovative technique makes PVP safe and effective. Although it lasts longer, the restoration rate of vertebral height and cement distribution can be improved, which contributes to a better pain relief.

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...

Nasal Cannula
A nasal cannula is a lightweight tube split at one end into two prongs and placed in the nostrils. It is typically used to deliver low to medium levels of oxygen.
Suggested flow rate: The suggested flow rate for a nasal cannula typically ranges between 1 and 6 L/min.

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...
