This report is being filed after the subsequent review of the following journal article: ¿growth-sparing spinal instrumentation in skeletal dysplasia.¿ the purpose of the study is to report the outcomes of distraction-based, growth-sparing spinal instrumentation in patients with skeletal dysplasia.Between 2004 and 2010, 12 children with a diagnosis of various types of skeletal dysplasia underwent growth-sparing spinal instrumentation for severe spinal deformities.Three of the patients were treated with vertical expandable prosthetic titanium rib (veptr).Of the 3 patients, one had a complication of proximal migration of rib cradle, which required revision, and the other 2 patients had anchor dislodgements, which were addressed during planned distraction surgical procedures.This report 1 of 3 for (b)(4) and is for one unknown veptr construct.¿patient no.2¿, a male, who was (b)(6) the time of surgery, had a complication of hook and screw dislodgement and proximal junctional kyphosis, which were addressed during planned distraction surgical procedures.
