In past blog posts we have presented
Magnetically-Controlled (MAGEC) Growing Rods.
was the three-part series on the following dates:
3-9-2017 MAGEC: Part 1
5-3-2017 MAGEC: Part 2
5-18-2017 MAGEC: Part 3
11-28-2021 a study on the use of MAGEC vs. Posterior Spinal Fusion vs.
Vertebral Body Tethering in 8-11 year old patients was presented
8-23-2022 we presented a comparison of the Shilla Growth Guidance system vs.
the MAGEC Growing Rods. This blog post
was a compilation of talking points for discussions with surgeons when these
constructs are options for treatment.
In this blog post we will demonstrate the use of MAGEC
Growing Rods in a patient with neuromuscular scoliosis due to spastic
quadriplegic cerebral palsy
This first figure shows an 8 year old boy with spastic
quadriplegic cerebral palsy (CP). He
uses a stander and gait trainer, and has pain in his back when sitting. There
is a 92 degree scoliosis (left picture) and 94 degree kyphosis (right
picture). It is common at this magnitude
of deformity that back pain occurs when sitting, which is very problematic if
they cannot stand and must use a wheelchair for all activities. These children may not be able to attend
school or take car ride due to back pain.
When the patient lays down the scoliosis improves from
92 to 65 degrees and the kyphosis from 94 to 29 degrees, which is VERY flexible
for a patient with CP.
As you see below the 92 degree scoliosis and 94 degree
kyphosis both improve to 44 degrees by placement of magnetically-controlled
growing rods (MCGRs) from T2 down to L5.
Stopping the growing rod short of the pelvis is possible since the hips
are level, which decreases the infection risk and preserves some motion of the
The below slide is 4 years and 3 months after surgery.
The MCGRs have been lengthened 8 times in the office over that time period. No
surgeries have been done over those 4 years, 3 months. The two yellow arrows point to the area on
each growing rod that has been lengthened.
The last slide shows how the spine deformity has
improved…..with the MCGRs. Treatment is
