What describes the McCash method for treating Dupuytren's contracture?

1. Excising the entire palm with skin grafts

2. Transverse incisions without skin grafts

3. Use of a dynamic extensor splint

4. Rotational procedures for joint mobility

The correct answer is: Transverse incisions without skin grafts

The McCash method for treating Dupuytren's contracture is accurately described by the approach that involves making transverse incisions without the need for skin grafts. This surgical technique aims to release the contracted bands of fascia that lead to the characteristic flexion deformities in the fingers. One of the key advantages of the McCash method is that it minimizes the need for extensive skin mobilization or grafting, which can complicate recovery and lead to additional complications. Instead, the transverse incisions allow for direct access to the contracted cords while maintaining the integrity of the surrounding tissue. This can lead to a more straightforward healing process and an overall better functional outcome for the patient. In contrast, methods that involve excising the entire palm with skin grafts would generally result in greater surgical trauma and longer recovery times. The use of dynamic extensor splints and rotational procedures for joint mobility, while relevant in the context of rehabilitation and recovery, do not pertain to the specific technique of the McCash method in the surgical treatment of Dupuytren's contracture.
