DUAL MOBILITY: A STéPHANOIS CONCEPT (ST ETIENNE AREA, FRANCE)
It was Gilles Bousquet who has the merit of having first defined the original concept of dual mobility. The prosthetic head is mobile within a retentive polyethylene which is free to move within a metalback cup (figure 1). Figure 1 : The principle of dual mobility ... Read More

 Tribute

In 1969 I was running an applied mechanics laboratory at the Ecole Catholique des Arts at Métiers – ECAM - in Lyon. A phone call from one of my suppliers in scientific materials, informed me that one of his cousins, Head of Clinic in Orthopaedics at the Hospices Civils de Lyon, was looking for an engineer to work on an innovative project; making a knee prosthesis. Naturally I hesitated before meeting this surgeon given my lack of knowledge in anatomy, but accepted to meet with him ...

The main problem with dual mobility cups in the medium term is intraprosthetic dislocation. The head comes out of the polyethylene through wear of the retentive rim. The head then lodges itself in the metalback shell which can be seen by a characteristic view on x.ray. (figure 1). Alas this type of incident is reported in all the literature on series of dual mobility cups, which is an indicator of this sad reality. ...

Operative management of Achilles tendinopathy is still considered in the orthopaedic world as minor and poorly coded surgery, due to the wide variety of anatomopathological forms and lack of accuracy of the techniques available. However, as any surgical repair, it requires careful assessment of the lesions and the use of an appropriate surgical technique to ensure a successful outcome. Surgical treatment for Achilles tendinopathy began to develop in the 1980s, after Jenkins' experiments in sheep ...

INTRODUCTIONArthroscopic rotator cuff repair is a recently developed technique that is gaining increased popularity. To make arthroscopic rotator cuff repair a straightforward, standardized procedure, we have designed a special technique based on the tension band principle, using between 2 and 5 inverted horizontal mattress sutures placed through the tendon and anchors placed in the lateral cortex of the greater tuberosity (Fig. 1). ...

Why write an article specifically on GCT (giant-cell tumor) ?This decision has been carefully thought through : as a giant-cell tumor (GCT) can be benign or malignant, an in-depth study of GCT provides the essence of what one needs to know about tumors and their variants, as well as the technical tricks regarding curettage & bone-grafting which is the classical treatment for all benign intraosseous tumors. An overview of the malignant forms of GCT gives an idea of the resection-reconstruction techniques ...
