title: [Pseudarthrosis of the scaphoid bone. Experiences in 240 cases].
abstract: The results after treatment of 197 non-union of scaphoid fractures are reported. The operative technique of Matti-Russe, called also Russe I, has proved successful in cases in which the fracture is located in the middle or distal third of the scaphoid or where there is a viable small proximal fragment. Bone healing depends more on the age of the pseudarthrosis than on the age of the patient. In 86% of 83 cases the technique of Russe I was successful and in this group the period between accident and treatment was no longer than two years. After a period of more than four years after the accident the success rate is only 54%. The combination of the technique of Russe I with styloidectomy of the radius diminishes the number of good results. The operative technique known as Russe II assumes a good blood supply of the distal fragment of the scaphoid. In 15 cases, after resection of the necrotic small proximal fragment of the scaphoid, a fungiform bonegraft from the iliac crest was placed in the cavity and the success rate was 80%. The findings after palliative treatment of 43 non-unions of the scaphoid are based on subjective criticisms by the patients. The denervation of the wrist and the wrist arthrodesis were done in 28 cases. After resection of the necrotic proximal fragment, a tendon interposition arthroplasty was performed in nine cases, and in six cases a prosthesis for the proximal part of the scaphoid was implanted.
