[Different indications for endoprotheses of the hip joint (ceramics (Al2O3) or internal shells?) (author's transl)].

The internal shell endoprothesis for the hip joint after Wagner has considerably limited the indications for the implantation of ceramic endoprotheses to patients under 60 years, because less bone substance has to be sacrificed. Furthermore there are indications for ceramic endoprotheses in cases of substance defects of the femoral head and neck, to some extent also in cases of dysplasia and protrusio acetabuli, and by loosening traditional total hip endoprotheses.

[Management in avascular necrosis of the femoral head (author's transl)].

For differentiated indication for operative treatment of avascular necrosis of the femoral head following points have to be considered: age, sex and profession of the patient, precedent treatments, state of contralateral and neighbouring joints. -- Methods of operation: Osteotomy for redistribution, filling with spongious bone and muscle-pedicle-bone graft, transplantation of homeoplastic osteochondral cups of the femoral head, Smith-Petersen-Cup arthroplasty- alloarthroplastic replacement of the femoral head, total replacement of the hip joint, resection of the femoral head and angulation-osteotomy of the diaphysis, arthrodesis of the hip joint. These methods are discussed with regard to personal conditions, surgical techniques, postoperative treatment as well as their advantages and disadvantages. There is no causative treatment of avascular necrosis of the femoral head. Therefore it is especially important to use the different methods appropriate to the special situation.
