Treatment outcomes about colles′ fractures with plaster immobilization on wrist in different position

Objective To analyze the treatment outcomes of colles′ fractures with the plaster immobilization on wrist in different position after mechanical reduction and the evidences of anatomy and biomechanics.Method A retrospective analysis was on a total of 426 patients suffering from dislocation colles′ fractures treated with the plaster immobilization of the wrist in dorsal-flexed position and palmar flexed position after mechanical reduction.A hundred and ninety-six of them were immobilized the wrist in palmar flexed position,others were immobilized the wrist in dorsal-flexed position.They were followed up for 0.5～4 years,with an average of 2.4 years.The re-dislocation cases and the excellent and good results was assessed by Gatrland and Werley score.Results The plaster immobilization of the wrist in dorsal-flexed position had less re-dislocation cases(P0.01)and more excellent and good results(P0.01).Conclusion The plaster immobilization of the wrist in dorsal-flexed position after reduction treating colles′ fractures has better outcomes,less complication.The functions of wrist recover well.
