[Regeneration of a diaphyseal segment of the radius (author's transl)]. / La régénérescence diaphysaire d'un os long chez l'enfant.

The osteogenesis potential and the subsequent skeleton reconstruction are well known in young children. Our case illustrate these two features. A six years old patient had lost the entire radial diaphysis during an open trauma of the forearm ; after the debridement of the wound, the limb was simply immobilized in a cast leaving off the radial diaphysis. Six months later an antomical reconstruction of the radius was obtained with a very good function.

[Surgery of retrospinal disinsertion of the posterior cruciate ligament of the knee (author's transl)]. / Le traitement chirugical de la désinsertion rétrospinale du ligament croisé postérieur du genou.

Thus in all cases of an isolated tear of the posterior cruciate ligament, with an interglenoid fragment, whe fixation by a screw or clip was carried out, we obtained good results by simple surgical treatment. In spite of the small size of this series, the results were in perfect harmony with those of other authors, which justifies surgery. In three other cases of a tear of the posterior cruciate ligament, orthopedic treatment was adopted for various reasons; comparison of the results was definitely in favour of surgery owing to the duration of plaster immobilisation and physiotherapy in the first group and the functional sequelae with chronic invaliding laxity in the cases treated conservatively.

[Fascicular nailing of the femur and tibia. 14 years' experience. Report of 275 cases (author's transl)]. / L'enclouage fasciculé du fémur et du tibia. 14 ans d'expérience. A propos de 275 clous.

The use of the fascicular four-pin nail has been introduced to correct certain inadequacies revealed by the rigid nailing according to Kuntscher's method; made up of four tiny pins soldered at each end, it fits the curve of the bone; its elasticity allows a much greater resistance to repeated strain as compared to other nails; an experimental study which compares the stability of fresh femurs cut then nailed according to different methods, reveals a definite superiority for the fascicular nail. The clinical use for 14 years (275 nailings among which 92 cases werefresh closed fractures of the femur) confirms that such a method provides the advantage of nailing without reaming as well as the possibility of immediate weight bearing ambulation for most patients (75% in the cases of resh femur or tibia fractures).

[Is conservative treatment justified in the case of advanced infantile tuberculosis of the hip? (author's transl)]. / L'intervention conservatrice dans la coxalgie évoluée de l'enfant est-elle justifiée?

In the case of advanced children tuberculosis of the hip, the authors propose a more active treatment than Wilkinson's, which is less conservative. A local curetting is important, and if the acetabulum reveals a geodic aspect, this surgery may be done by pelvic approach. After an orthopedic traction, the surgical method is more efficient and permits better flexibility of the hip, only to be noticed under general anesthesia. After surgery, this traction must be prolonged for a several months and kinesitherapic mobilisation must be associated. The excellent result, both clinical and radiographic obtained by the authors seems to justify the use of the above mentioned method.
