Abstract
STUDY DESIGN
Retrospective study of 8 children treated with vertical expandable prosthetic titanium rib (VEPTR) for correction of early onset spinal scoliotic deformities.
METHODS
8 children with progressive scoliosis due to a variety of conditions, 6 congenital (2 Goldenhar syndrome, 2 VACTERL syndrome, 2 congenital thoracic abnormalities), 1 spondyloepiphyseal dysplasia, 1 early onset of scoliosis, underwent the index procedure and subsequent lengthening procedures at 6 months intervals (1 patient had 11 lengthening procedures).
Mean age was 4 years (2-6 years) and mean follow up 3.8 years (2-6 years). Mean preoperative Cobb angle was 64,8° (51-108) and mean postoperative angle 40° (31-50)
RESULTS
There were no neurological complications. Three patients developed infection with wound breakdown. One patient underwent removal of one of the two VEPTR rods. In the other two patients the rods were removed followed by antibiotics and the VEPTR converted to another growing rod system. Overall, patients tolerated the multiple procedures well. Three patients experienced significant distress with multiple surgical procedures.
CONCLUSION
VEPTR offers a viable treatment option for children with severe congenital and early onset scoliosis where there are no viable alternatives. It achieves and maintains spinal deformity correction, while allowing for continued spine and chest-wall growth. Complication rate is acceptable in view of the benefits. None of the complications have lead to long term complications to date, but the repeated lengthening have resulted in psychological disturbance which we are investigating further. An implantable driver would offer very significant advantages and would avoid some of the repeated operations.
