Question

What do the following Structures become in Buck Gramcko Pollization?

1) EDC becomes Extensor Digitorum Communis
2) EIP becomes Extensor Indicis Proprius
3) 1st DI becomes First Dorsal Interosseous
4) 1st PI becomes First Palmar Interosseous

Answer 1

The Buck-Gramcko pollicization is a surgical procedure that may involve renaming or modifying muscles in the hand and forearm to reconstruct a functional thumb. The specific muscles in question, such as the EDC, EIP, 1st DI, and 1st PI, are essential for hand and finger movement.

Step-by-step explanation:

The question concerns the anatomical structures within the human hand and forearm, focusing primarily on the muscles and their nomenclature in medical terms. Specifically, the student is asking about the renaming of certain muscles or muscle groups during a particular procedure known as the Buck-Gramcko pollicization, often performed to reconstruct thumbs, particularly in cases of congenital anomalies or traumatic injuries.

• EDC or Extensor Digitorum Communis is a muscle that extends the fingers and is part of the dorsal group within the forearm region.
• EIP or Extensor Indicis Proprius extends the index finger and inserts onto the extensor digitorum tendon of this finger.
• 1st DI or First Dorsal Interosseous is a muscle that abducts and flexes the middle fingers at the metacarpophalangeal joints.
• 1st PI or First Palmar Interosseous is involved with the adduction and extension of fingers.

These muscles are critical for the function and mobilization of the hand, especially after reconstructive surgeries like pollicization.
