Do baclofen pumps influence the development of scoliosis in children?
Bibliographic record
Abstract
OBJECT: Intrathecal baclofen is an effective treatment for spasticity in patients with cerebral palsy. There has been increasing concern, however, that intrathecal baclofen may accelerate the development of scoliosis in this population. To this end, the authors reviewed their population of pediatric patients with baclofen pumps to assess the incidence of scoliosis. METHODS: This was a retrospective chart and radiology review of all pediatric patients with baclofen pumps. Cobb angles were measured preoperatively and on follow-up images. RESULTS: Of 38 patients identified, 32 had adequate data available for inclusion in the study (16 with cerebral palsy, 7 with dystonic cerebral palsy, 4 with head injury, and 5 with other diagnoses). The mean age at pump insertion was 10.6 years and the mean follow-up period was 31 months (range 1-118 months). The mean annual Cobb angle progression was 19 degrees (range 0-68 degrees, median 12 degrees). CONCLUSIONS: In the authors' group of patients there was notable development and progression of scoliosis at a greater than previously reported rate for the same patient population, and also greater than previously reported patients with intrathecal baclofen pumps. The largest possible confounding factor in this study was the insertion of the pump before skeletal maturity and therefore coinciding with the time when scoliosis may be developing naturally. A prospective study is recommended to gather further data on the development of scoliosis in this particular population with intrathecal baclofen pumps.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
