[An original procedure for cement diaphyseal extraction. The segmental cement extraction system or SEG-CES].

Purpose Of The Study: We report our first eleven uses of a new cement mantle extraction system. The basis of this technique relies on a cement bone interface with a lower strength compared to the old cement-new cement interface.

Material And Methods: The first stage of the procedure consists in a specific preparation of the inner surface of the old cement, mantle.

[Ilizarov method used for the sequela of growth cartilage lesions].

Ilizarov distraction osteogenesis is a good way to correct sequelae of growth plate injury after completion of the growth. There is often both limb length discrepancy and angular deformation in varus, valgus, flexum, and recurvatum after surgery or trauma in childhood. Such deformations of the distal femoral growth plate, both proximal and distal tibial and distal radial will be presented, treated by a one-step Ilizarov method.

[Tenosynovial osteochondromatosis of the hand. A case report].

A 14 year old boy presented with swelling of the middle finger. X-rays showed calcifications of the palmar surface of the head of the third metacarpal and over the first and second phalanges. The natural course was followed over a period of two years with a diagnosis of calcifying peritendonitis.

[First-choice orthopedic treatment in congenital hip dislocations discovered after walking age].

The incidence of late discovery of congenital dislocation of the hip is getting lower, thanks to systematic screening. We have treated 14 children during the past 5 years. Clinical diagnosis was confirmed by radiography.

[Thalamic fractures of the calcaneus. Value of computed x-ray tomography in therapeutic decisions].

The authors have studied 35 fractures of the calcaneal thalamus and compared the information provided by plain radiology and CT scans of the calcaneal tuberosity, especially those connected with the condition of the posterior subtalar joint. In 8 cases out of 35, the study of the CT sections yielded information that allowed changing the indications for treatment. The authors emphasize the quality of the data obtained, which makes it possible to justify a functional treatment or to establish a preoperative schedule.
