By J. A. Ogden, H. L. Moss (auth.), U. H. Weil (eds.)

Readers of the 1st quantity of growth in Orthopaedic surgical procedure might be mindful the introductory comments of Drs. Wagner and Hungerford. it's the purpose of the editors of this e-book to familiarize English - talking orthopaedists with articles released within the eu literature which, due to language limitations, may rather be inaccessible to them. such a lot articles during this moment quantity are also translations of papers initially published in Der Orthopiide. the aim of this German clinical magazine is to disseminate the latest studies of orthopaedic difficulties in a kind that's of specific price to the practicing orthopaedic physician. In 1973 8 articles have been released on acetabular dysplasia. In his fore­ observe to this factor Dr. Wagner said a number of the the reason why such an indepth learn used to be deemed beneficial. He was once of the opinion that the vanity and elevate in acclivity of the acetabulum was once of such crucial significance within the improvement and remedy of hip dysplasias quantity facing this topic used to be totally justified. one more reason for this choice of papers was once the advances made in correcting the result of a dysplastic acetabulum through surgical skill and thereby bettering hip joint functionality in later years, or at the least pre­ venting its early deterioration.

Sample text

If untreated this hip probably progresses to a more severe subluxation or even complete dislocation. The hip usually has more severe flexion and adduction contractures, and as the extensorl abductor groups (especially gluteus medius and minimus) become more active postnatally, they may pull the positionally susceptible proximal femur superiorly and/or posteriorly, accentuating the marginal eversion. During this stage the first traces of inversion of the limbus may be discerned. It appears that inversion may not be an abrupt phenomenon, but rather a gradual process of hypertrophy and ingrowth of that portion of the fibrocartilaginous labrum adjacent to the hyaline cartilage.

However, the major contributions throughout most of this development, particularly during the critical first 2-3 years of life, come from the posterosuperior branches. Figure 30 shows a specimen from a fifteen-month-old female with untreatedCDH. The vascular injection was done with India ink, using the abdominal aorta. Despite the chronic dislocation, the India ink penetrated into the vessels within the cartilage. The figure demonstrates both the posteroinferior and posterosuperior systems. As can be seen several large vessels are penetrating from the posterosuperior region.
