Treating scaphoid nonunion effectively depends on fragment vascularization and stability. Surgical options like bone grafting or vascularized pedicle bone transplants offer bony union for wrist fractures.

Area of Science:

  • Orthopedic surgery
  • Hand surgery
  • Musculoskeletal research

Context:

  • Scaphoid nonunion presents challenges due to secondary wrist and carpal changes.
  • Treatment selection is dictated by fragment vascularization and nonunion characteristics.

Purpose:

  • To review operative procedures for scaphoid nonunion.
  • To evaluate surgical techniques based on fragment vascularization and stability.

Summary:

  • Bony union is achievable with autogenous free bone grafts in well-vascularized fragments.
  • Vascular pedicle bone grafts are recommended for extensively impaired blood supply.
  • Postoperative stability is crucial for nonunion consolidation.
  • Standard surgical methods including Matti-Russe I, Russe II, vascular pedicle bone transplant, and Herbert screw are presented.
