Abstract
Objectives: To study clinical features of digital flexor sheath. Methods: An observational anatomic study on 26 cadaver hands which were dissected and studied to conclude several anatomic features of the digital flexor sheath contributing to the management of the flexor sheath injuries in clinical practice. Results: The average length of A1, A2, A4 pulleys in the long fingers were 7.11mm, 16.12mm, and 5.94mm, respectively. The average width and thickness of A2, A4 pulleys in the long fingers were 6.25mm x 3.68mm and 4.98mm x 2.90mm, respectively. The distances from the MCP joint to the proximal border of A2, A4 pulleys on the same digitorium were 6.35mm and 7.96mm, respectively. Conclusion: A2 has the longest length and biggest cast thickness and width.
