[Experience with acetabuloplasty according to Pemberton (author's transl)].

Following a brief description of the conventionally most well-known acetabuloplastic procedures for correcting hip dysplasia, the article gives details on acetabuloplasty as described in 1965 by Pemberton. Only few reports on experience collected with this method of operation have been published. The authors' own earlier evaluations and medium-term treatment results after 53 effected operations show that this procedure will mostly bring about a definite improvement of the acetabulum by reducing the acetabular inclination angle (AC angle) and correspondingly increasing the angle between the centre and the craniolateral corner of the acetabulum (CE angle). During the observation periods reported by the authors, an average reducing of the AC angle by 12 degrees was achieved, whereas the CE angle was increased during the same periods by an average of 17.5 degrees. Basic requirements for this operation are good centering of the head of the femur, which must be created, it necessary, via an open positioning of the hip joint or by intertrochanteral osteotomy; in addition, the Y-shaped piece at the botton of the acetabulum must be open, as will be seen from the roentgenogram.

[The fixing shoe with rolling sole (arthrodesis shoe) with interchangeable built-in-element (author's transl)].

The fixing shoe with rolling sole (arthrodesis shoe) serves to ensure pain-free or at least tolerably painless walking in case of changes due to arthrosis or lesion sequelae in the ankle joints or the tarsus. This is achieved by means of a high shaft of adequate strength, an accurate bedding of the foot, and a rolling sole with sufficient lift at the tip. This shoe is indicated in cases where the load alone is well tolerated whereas load in conjunction with movement produces pain. Several types of these orthopedic shoes have been developed. Of these, the model with interchangeable built-in element has proved most successful in the authors' experience. This built-in element consists of a drummed (milled) cap reinforced with cast resin, and a cork bedding. This removable or interchangeable unit is advantageous compared with a firmly integrated system insofar as any changes or repairs can be effected easily and at a lower cost.
