Abstract:
Objective To investigate carpal instability after distal radial fractures have been treated with cast immobilization or operation and its effect on clinical functions.Methods 124 patients with distal radial fracture were treated with cast immobilization,external fixation or plate internal fixation.They were followed up.Their carpal instability was evaluated according to X-ray manifestations before and after treatment;their clinical carpal functions were assessed according to Gartland and Werley scoring system.Results The follow-ups revealed five types of carpal instability:palmar or dorsal shift of the carpus,VISI(volar intercalated segment instability),DISI(dorsal intercalated segment instability)and scapholunate dissociation.The incidence of carpal instability was 58.1%before treatment,21.8%after treatment and 22.6%at the follow-ups.Functional results were excellent and good in 80.6 %of the total patients,in 84.5%of those in the stability group,and in 75.0%of those in the instability group.Conclusions Distal radial fractures usually lead to carpal instability.Operations can correct radius-carpal instability effectively,but it is difficult to correct scapholunate dissociation.The function of carpal joint is evident ly poorer in patients with carpal instability than in those with carpal stability,for it is mainly affected by the integrality of radius-carpal joint.
