Dupuytren's disease is a common fibroproliferative disorder that primarily affects the palm of the hand. While the disease is known for its characteristic palmar contractures, it also has a potential impact on the extensor mechanism of the hand, resulting in the development of boutonniere deformity, swan-neck deformity, and persistent metacarpophalangeal joint contracture due to extensor capsule stretching and tendon instability. These imbalances are challenging to correct under general or regional anesthesia. Wide awake local anesthesia without a tourniquet allows active range of motion and intraoperative patient collaboration. By understanding the underlying mechanisms and structures involved in these deformities and correcting them under local anesthesia without a tourniquet, hand surgeons can become more confident in correcting the deformity, demonstrating it to the patient, optimizing the rehabilitation protocol, and improving patient outcomes.
