SpineJack – Anatomical Restoration
SpineJack offers surgeons a controlled and minimally invasive solution to treat vertebral compression fractures. It allows a safe anatomical restoration and following stabilization of the vertebra.
SpineJack is available with three different sizes for the best possible three-dimensional adaptation to the anatomy of the vertebral bodies.
As for any other weight-bearing joint, spine fractures deserve to be treated by a stable anatomical reduction and a stabilization. These both steps combined allow for a biomechanical restoration due to an early mobilization and weight bearing. Anatomical reduction means restoration of the geometry of the whole vertebra, that is cortical ring and endplates.
- Cortical ring reduction consists of vertebral angle restoration which is the key for kyphosis management and consecutive adjacent fracture avoidance
- Vertebral endplate restoration has been described as having a positive influence on disc creeping, disc degeneration, compensatory curvatures or facet joint arthritis.

How does SpineJack work?
Promising longterm results
First clinical Studies indicate a lower rate of adjacent fractures, compared to traditional methods.
Several clinical and epidemiological studies have shown a correlation in between vertebra deformation and clinical problems such as post-traumatic kyphosis, which has been depicted as one of the most potentially serious post-traumatic deformities. A SpineJack treatment can relieve patients mostly from this pain.
Within this context, VEXIM has designed the SpineJack implant to provide clinicians with a fully controlled solution for VCF treatment enabling first an anatomical reduction and second a safe stabilization.
What are the advantages?
The SpineJack system is indicated for use in the reduction of mobile spinal fractures that may result from osteoporosis, trauma fractures types A according to the Magerl classification and malignant lesions myeloma or osteolitic metastasis.
The SpineJack system is intended to be used in combination with validated bone cement, and to be placed, using a transpedicular approach, through a vertebra pedicle with a minimum internal diameter, as verified with a pre-operative CT scan.
- Controlled cranio-caudal expansion
- Maintenance of the restoration before cement injection
- Preservation of bone trabeculae
The SpineJack technique is well documented in published studies in highly respected scientific journals with focus in all type of indications leading to vertebral fractures.

Anatomical Restoration with SpineJack
Vertebral fractures are a common pathology and can significantly affect the quality of life. If they are not treated early enough, even the daily tasks can no longer be performed.
Back pain, loss of appetite, sleep disorders or respiratory problems are some examples of typical symptoms. If your doctor has diagnosed you with a vertebral fracture, a minimally invasive procedure is a treatment option to consider.
Minimally invasive reconstruction of the vertebral body with the SpineJack method
The minimally invasive surgical procedure allows to relieve pain, reduce the vertebral fracture and restore the original shape of the vertebral body. The intervention can be performed in the interventional radiology department or in the operating theatre with very strict sterility and safety standard.
The operator makes two small incisions, approximately one centimeter long, on your back and creates a narrow target path to the fractured vertebral body to insert two implants.
He then places the implants and injects bone cement into the vertebral body to stabilize the restored vertebra. The procedure is usually performed under general anesthesia but can be done under local anesthesia depending on what your doctor recommends.
The procedure takes about 30 minutes for one vertebral fracture, with additional preparation and recovery time.

General Risks Associated with Surgical Intervention
Although the complication rate for minimally invasive procedures has been shown to be low, this procedure, like any surgery, is associated with risks of heart attack, embolism and infection. Please note that this intervention is not suitable for all patients.
Please discuss the risks with your doctor and ask them if this intervention is suitable for you.
After the Surgery
Immediate Pain Relief
Usually, patients report immediate pain relief after this procedure. However each patient experiences pain in a different way, so a mild pain reliever can be prescribed for a few days.
Almost Immediate Return Home
Usually, patients stay up to 3 days in the hospital after the surgery.
Quick Return to Work and Daily Tasks
After leaving the hospital, you will probably be surprised of how fast you can go back to work and perform your daily tasks.
Your doctor should give you a follow-up appointment where he will give you specific instructions to follow, depending on your recovery and your general health and physical conditions.
