Background. Pseudoarthrosis of the scaphoid results in the development of carpal instability and severe posttraumatic osteoarthritis. Modern methods of treatment focus on reconstruction of the anatomical shape and length of the scaphoid. The purpose of our study was to determine the occurrence of carpal osteoarthritis after surgical treatment of scaphoid pseudoarthrosis using a cortico-cancellous bone grafting technique. Material and methods. 48 patients who had undergone surgical treatment for scaphoid union failure were examined. The surgical method included the anatomical reconstruction of the scaphoid bone, which resulted in normal ligament tension and carpal stability. The clinical examination included pain evaluation, return to work, range of wrist motion, and grip strength. On comparative x-rays of both wrists we evaluated union, the length and shape of the scaphoid bone, the scapho-lunate angle, the carpal height ratio, and the carpal ulnar shift. Results. Union was obtained in 42 cases. In 26 patients there were no signs of osteoarthritis, while 11 patients had slight degenerative changes in the radio-scaphoid joint. Conclusions. According to our analysis, cortico-cancellous bone grafting is an effective surgical procedure, useful not only in obtaining union, but also in reconstructing the shape and length of the scaphoid and preventing posttraumatic carpal asteoarthritis.
