Preoperative intramuscular injection of botulinum toxin prior to hip surgery in a patient with cerebral palsy

Background: We report on a 47-year-old man with tetraspasticity due to cerebral palsy requiring total hip joint endoprosthesis because of hip dysplasia in whom botulinum toxin A was applied preoperatively to reduce the high risk of postoperative luxation due to an increased flexor and adductor muscle tone at the right hip.

The primary outcome measure was self-reported pain relief, muscle tone and limb position. The tone of the right hip f…
