Introduction: Arthrodesis of the wrist must still be considered as a useful procedure in the treatment of certain deformities of the wrist joint that by performing this operation can improve the function or the aesthetics of the limb. Except those techniques of partial carpal arthrodesis, the surgical procedures of wrist arthrodesis requires a bridging from the radius to the metacarpal in order to stabilize the joint. When this procedure is performed in a growing child this can be a draw back.

Material: We have developed a new procedure that producing the arthrodesis distally to the growing cartilage of the radius does not interfere with the growing at wrist level. Furthermore, the use of a wire shroud gives an active fixation reducing postoperative immobilisation and shortening healing time. Since 1986 we have performed this technique in 9 cases of children with mean age of 14 years. The pathology was in 5 cases Cerebral Palsy, in 2 cases Juvenile Rheumatoid Arthritis and in 2 cases Obstetrical Brachial Plexus Palsy. Eight cases were males and 3 cases females. The indication for surgery was flexion deformity of the wrist in 8 cases and extension in 1 case. Four cases had carpal instability (including the 2 Juvenile Rheumatoid Arthritis).

Results: The time of fusion was in all cases 2 months with primary arthrodesis and improved extremity. Functional improvement seemed to be most related to pre-operative conditions. Follow up ranged from 4 years to 6 years.

Conclusions: The good results obtained with this procedure encourage us to present this new surgical technique to be applied in the still growing child.
