[Treatment of patello-femoral arthrosis by anterior displacement of the tibial tuberosity (Maquet procedure)].

The authors have treated 71 cases of patello-femoral arthrosis by anterior displacement of the tibial tuberosity to diminish pressure of the patella. In most cases, an osteotomy of the tibial crest was made and forward displacement maintained by the addition of a bone graft. The medial and lateral patellar retinacula were divided, the patellar articular cartilage was shaved and fine drill holes made in chondromalacic cartilage. The results were satisfactory in 75% of cases but the follow-up was short (about one year). It was concluded that the tibial tuberosity should be displaced forward by about 2 centimetres. The surgical technique is fully described.

[Chairi pelvic osteotomy in adults. Technique, biomechanical study and early results in 21 cases].

The authors have reviewed 14 cases of Chiari pelvic osteotomy performed in adults and followed up during more than one year. They describe the bio-mechanical properties of this procedure, and a surgical technique with some original modifications. They conclude that this operation may be contra-indicated in young women for obstetrical reasons. It is indicated in degenerative arthritis of the hip at an early stage when acetabulum is dysplasic or the femoral head subluxated.

[The stress in femoral prosthesis: a study of the importance of the diaphyseal support and horizontal setting (author's transl)].

This study by strain-guauge methods trends to estimate relative stress in the fresh, adult human cadaver femur, before and after implantation of a cement-free (madreporique) prosthesis with a trochantero-diaphyseal support. In contrast with Blaimont, Oh and Harris statements (after insertion of a conventional femoral component with an oblique setting over the femoral neck and a short stem, the pattern of strain in the proximal part of the femur is reversed compared with that in the intact femur, the maximum strain occuring around the tip of the prosthesis rather than at the calcar femorale), the Authors found that a dihedral foundation--with an horizontal setting of the prosthesis over the calcar--, and a long stem do not reverse the normal pattern of strain in the femur. This biological balance is necessary to bone-ingrowth development for implant anchoring. This "in vitro" study does not deal with this bony fixation but intends to approximate the initial static requirements, just after the uncemented prosthetic insertion, for such a bone ingrowth.
