[Treatment of pseudarthrosis of the carpal scaphoid bone by percutaneous pinning. Apropos of 74 cases].

From 1985 to 1997, 74 patients was operated of scaphoid non union at the Kassab Institute by a percutaneous pinning as described by Galluccio. The average age is 30 years with an extreme from 17 to 48 years. Union was obtained after an average of two years and six months. In 12 cases the delay was superior than three years. Functionally, pain is a constant cause of consultations and the majority of patients presented a reduction of the mobility sector (80%) and the strength of grasp (70%). Anatomically, it is particularly a pseudarthrosis stage II a of Alnot, and type I b of our classification. An immobilisation post-operative during one month is the rule. The analysis of results at an average of four years, revealed 91% of clinical recovery. Radiographically, the union is obtained in 89% of cases. Our fails (11%), are explained by an inadequate mounting and particularly by the length of pseudarthrosis. Compared to other means of synthesis, the percutaneous pinning of Galluccio, is an inexpensive technique, easily and rapid, which permit to obtain an interesting results particularly in the recent pseudarthrosis (evolution delay below three years).
