Sixteen patients with scoliosis were treated with Harrington-rod
instrumentation supplemented by methylmethacrylate fixation at the
distraction sites to reduce the possibility of dislodgement of a hook due
to inferior bone stock or the patients' inability to cooperate
postoperatively because of mental insufficiency or involuntary-movement
disorders. Follow-up ranged from six to thirty-eight months (average,
fourteen and one-half months). There were no complications related to the
use of methylmethacrylate in these patients.
