A comparative study on autologous bone grafting combined with or without posterior interosseous nerve neurectomy for scaphoid nonunion treatment

摘要

Background and aim: Scaphoid nonunion (SN) is a challenging state after scaphoid fracture. The posterior interosseous nerve neurectomy (PINN) is often performed adjunctively with scaphoid reconstruction using autologous bone grafts. However, it remains unclear whether PINN has a prophylactic or therapeutic value, and thus it results superior to patients with SN without PINN.
