Why would my doctor suggest getting botox for an abductor contracture?

Improve contracture?: Actually Botox is indicated for muscle spasticity. If the spasticity persists for a long period of time then a contracture can develop. After this happens Botox is less likely to help, but may be an option prior to surgical release.

Relaxation: Botox can help the muscle relax if they are contracted. It can be an effective treatment.

Botox: Paralyzes muscles locally. A muscle contracture needs to be relaxed to improve it. Botox works well in this situation.
