  • Title: Vascularised pisiform bone graft. Indications, technique and long-term results.
    Author: Kuhlmann JN, Kron C, Boabighi A, Baux S, Mimou M.
    Journal: Acta Orthop Belg; 2003 Aug; 69(4):311-6. PubMed ID: 14526634.
    Abstract:
    The authors report their experience with the use of a vascularised pisiform bone graft based on the dorsal branch of the ulnar artery to provide osseous support and an efficient vascular aid especially in non-unions of the carpal navicular bone with avascular necrosis of its proximal pole and in stage III Kienböck's disease. The pisiform can replace the proximal pole of the navicular bone in totality. When implanted into the lunate, it stops its collapse and helps to revascularize it. The authors present the results achieved in 14 patients (12 male, 2 female), of which eight had a follow-up longer than 5 years The technique appears as an interesting alternative to carpectomies and partial intracarpal fusions which are usually proposed in advanced cases of these conditions.
