Abstract: While the indications and the technique for the hip arthrodesis operation have been thoroughly treated in the literature, the problem of the best position for the hip is usually dismissed in a few lines; often a particular position is recommended as giving "the best results" but the grounds for the choice are rarely specified; nor does the relationship between position and function seem to have been analysed in a followed-up case material.The following recommendations have been made in respect of the transverse, frontal and sagittal planes.Position in the transverse plane.-Thepreferred angle of rotation ranges from the mean to an outward rotation of 15" (2,3,6,7,9,10,14, 17).Inward rotation is considered to be incorrect.Wafson-Jones (16, 17) specifies the mean position, stating that any other recommendation "is of course nonsense".A s a rule no information is given on how the angle was measured.Position in the frontal plane.-Abduction between 0 and 25" have been mentioned (2,3,6,7,8,14,17) 25" being regarded as acceptable for children, while for adults 20" is the maximum.It is commonly held that any real shortening shall be compensated for by abducting the leg, and tables giving the appropriate abduction for different degrees of shortening have been compiled (1,9,10).Some authors caution against excessive abduction, recommending up to 10"; others prefer the zero position on the grounds that static scoliosis is liable to lead to back troubles.No objective examination of the possible connection between 1 Radiologist.
