[Problems of hip arthrodesis (author's transl)].

A follow-up study of 84 hip arthrodesis is reported. Four methods of arthrodesis were applied: nailblock arthrodesis, double-nail, cross-plate and screw arthrodesis. Double-nail arthroplasty was abandoned in favour of total hip arthroplasty. Moreover application of the screw was given up on account of relatively bad results. Nail-block and cross-plate arthrodesis, when indicated, are still very valuable therapeutic methods, especially in the case of patients who are too young for a total hip arthroplasty and who are still actively working. The influence of an arthrodesized hip on the knee joint and lumbar spine are examined and discussed.
