title: Arthroscopically assisted reduction and immobilization of intraarticular fracture of the distal end of the radius: several options of reduction and immobilization.
abstract: On the basis of preoperative computerized tomography scanning and newly developed 3-dimensional reconstruction technique, Doi classified intraarticular distal radial fracture to 2-, 3-, and 4-part type, according to the number of main fracture fragments in distal radial aspect. This classification system simply, as well as perspicuously, describes the status of joint surface, thereby providing an intuitionist and practical guideline for arthroscopy procedure. Between 1992 and 2003, 91 patients ranged from 21 to 79 years of age with intraarticular distal radius fracture were treated with an arthroscopically assisted operation at our department. Among these patients, 42, 34, and 15 cases were 2-, 3-, and 4-part type, accounting for 46%, 37%, and 17% respectively. Wrist arthroscopy was applied individually according to the different type, with the purpose of achieving <1mm reduction. Role of arthroscopy was postreduction examination for 14 cases, as K-wire guider in 13 cases, assisting reduction, and immobilization in 61 cases. Four of the 61 cases changed to ORIF. Immobilization methods include external fixator combined with K-wire or plate combined with pullout wire or screw. K-wire without other implant was applied to 6 cases. In 1 case, a screw was the only implant.
