[Computer tomography for rare soft tissue tumours of the extremities (author's transl)].

Five patients with undiagnosed soft tissue masses in the extremities were examined and in two a pathological diagnosis could be made. One was an extensive, invasive fibroma (desmoid) 22 cm long which could be followed from the thigh almost into the pelvis. It was sharply demarkated form the surrounding muscles and of higher density. The second case was a 12 cm long cavernous haemangioma in the semi-membranosus muscle. This was originally hypo-dense, but showed marked increase in its density after the administration of contrast.

[Preliminary report for cementless insertion of ceramic prosthesis (Al2O3) in exchange for a loosened total endoprosthesis].

In a series of thirty patients whose total hip prosthesis had become loose and had therefore to be replaced, first experiences were gathered with the implantation of a ceramic cup without any cement. Nineteen patients were provided with a ceramic cup, typ Lindenhof. Indication, operation procedure and postoperative treatment are particularly discussed. The postoperative review extends over a period of three to eleven month. A critical evaluation of the first results shows that the implanted ceramic cup was firmly integrated in the bone in spite of unfavorable anchoring conditions. This method proves to be helpful in cases when an aseptic loosening of the prosthesis has occurred, as it guarantees a painless function and a stable strain resistance.

[Bone tumours in the hip region (author's transl)].

13 Patients with bone tumours in the hip region are presented. The frequent misinterpretation auf tumours in this locality and the faulty use of diagnostic possibilities are stressed. The use of homoioplastic transplantation after a large resection is presented as a therapeutic method for discussion.

[2 Kirschner wires as simplified external fixation devices in finger joint arthrosis].

A new technique for arthrodesis of the PIP joint is described; after resection of the joint two percutaneous Kirschner wires of diameter 1.2-1.3 mm are placed transversely through the two phalanges. The wires are twisted together on each side of the finger to produce a compression effect on the bone surface. Additional external immobilisation is used for five days only, but the wires are left in place for six weeks. The method has been used without complication in ten patients. The average length of time off work was seven and a half weeks. In the author's view the advantages of this method lie in its technical simplicity and in the free movement of other finger joints.
