It has been reported that cerebral palsy patients with adductor spasm and lateralisation/subluxation of the hip can be treated with Botulinum toxin A, but statistical evaluation is lacking. We present the radiological results in 5 patients. The follow-up ranged from 18 (5 patients) to 24 months (4 patients). Reimers' migration percentage was chosen as parameter for lateralisation/subluxation. Statistical analysis was performed by the Wilcoxon test. The migration percentage improved from 51% to 44% at 9 months, 37% at 18 months, and 34% at 24 months. The improvement was significant from the 9th to the 18th month (p=0.04).
