neurologic navigation, a CT
scan is done intraoperatively. The O-arm uses
a special computer software produces
a 3D image of the spine. This allows the surgeon to
place the pedicle screws with uncompromised accuracy.
During the posterior spinal
fusion, the spine and its various components are manipulated
into balance. The structural and compensatory components
are equaled and balanced, and the spine is affixed. When
the surgery is completed the patient's spine is in perfect
sagittal and frontal plane balance.
Once the spine is balanced,
bone graft is gently laid down on the spine so that
a confluent fusion mass can occur. The graft material
is generally a combination combination
of the patient's own bone, donor bone, and a synthetic
substance called rhBMP.
Once the surgery is finished the muscles are anatomically
reaffixed to the bone and reattached. It should be
noted that muscles across fusion masses are not
a movable segment, therefore they do not contribute to
range of motion.
The closure is done with great care
to minimize scarring. The patient is returned to recovery,
and then transferred to a private room. Post-operatively
the patients are allowed to ambulate the day after surgery.
Approximately 10 days post-op, the patient has a wound check appointment with one of the nurses at Cedars Sinai Spine Center, or with their local physician. The picture to the right was taken at one month post-op.
