Dupuytren's contracture treated with botulinum toxin A injection.

Dupuytren's contracture is a condition in which fibromatosis of the palmar and digital fascia can lead to painful contractures of the hand. Common conservative treatments are of limited efficacy, while invasive options have risk of adverse effects. A 57-year-old female presented with chronic, bilateral hand pain secondary to Dupuytren's contractures. Traditional conservative treatments did not provide relief. She received a series of three botulinum toxin A injections into the palmar fascia of both hands, resulting in four months of improved hand function and pain relief. This case presents a novel treatment for Dupuytren's contracture using botulinum toxin injection. Botulinum toxin has inhibitory effects on the neuromuscular junction and pain signaling pathways to relax muscles and reduce pain. We believe its action on this patient's intrinsic hand muscles resulted in her improved hand function. Botulinum toxin injection can be considered as a treatment option for Dupuytren's contracture.
