What type of orthosis is recommended during sleep after Dupuytren's surgery?

Full hand immobilization splint
Wrist circumferential splint
Volar finger orthosis
Functional hand orthosis

The correct answer is: Volar finger orthosis

After Dupuytren's surgery, a volar finger orthosis is commonly recommended during sleep to support the healing process and maintain proper finger positioning. This type of orthosis allows for the fingers to be positioned in slight extension, which is crucial to prevent excessive flexion and potential contracture recurrence that may occur post-operatively. The distal positioning helps in facilitating optimal healing and minimizing the risk of complications by keeping the fingers functional and aligned. In the context of Dupuytren's release, other types of orthoses such as full hand immobilization splints might restrict movement excessively, potentially leading to stiffness and further complications. Wrist circumferential splints provide support to the wrist but may not adequately address the specific need for maintaining finger extension. Functional hand orthoses are typically used for rehabilitation phases post-surgery, focusing on promoting function and stability rather than the initial protective positioning needed during sleep right after surgery. Therefore, the volar finger orthosis is the most appropriate choice for ensuring the best environment for recovery following Dupuytren's surgery.
