Abstract:

OBJECTIVE: To summarize the methods and research progress of treating old scaphoid fractures using different implant materials.
METHODS: The PubMed database and CNKI database were searched by the first author using key words of “Carpal bone, fracture ununited” in title and abstract items. Papers related to material characteristics, biocompatibility and application results related to this paper were selected. In the same field, articles published in the near future or selected from authoritative journals were included. A total of 25 documents were selected.
RESULTS: Plaster cast was used to fix scaphoid fractures at early clinical works, however, because of the great fixation areas, long fixation duration, and poor fixation results, the recovery of range of motion was limited. The outcomes were satisfied when using bone flap and periosteum transplantation technology, combined with internal fixations, such as Kirschner wire, Herbert screw, hollow screw, to treat old scaphoid fractures. With the development of biotechnology, bone materials containing bone morphogenetic protein have been applied in the clinic and achieved good therapeutic effects.
CONCLUSION: Currently, bone flap transplantation has achieved satisfactory results in treating scaphoid fractures. Application of bone morphogenetic protein / fibrin composites can enhance the therapeutic effects. The compound of autologous periosteum-wrapped tendon and spongiosa homogenate can be used as the substitute for scaphoid in future.
