Compression-screw Fixation in Treating Carpal Navicular Fractures——A Report of 9 Cases / 第三军医大学学报

ABSTRACT

This paper is to report our experience of using the internal fixation with compression-screw to treat 9 fractures of carpal navicular bone including two fresh) two old and 5 non- union cases.The mean follow-up time of the 9 cases was one year. Two fresh and 2 old fractures healed uneventfully and so did the 2 cases out of the 5 non-unions. The symptoms, however, disappeared in all the cases and the function of the wrist was or nearly was normal. All the patients resumed their original work.It is believed that this method of internal fixation with compression-screw is simple and easy to perform. Its effect is reliable. No external fixation is needed after the operation. And the function of the wrist can be restored after a short period of treatment.It is suggested that the indications of this operative treatment are non-union cases without ischemic necrosis, unstable fresh fractures with displacement and fractures in the proximal third or half of the navicular bone.
