Biomechanics of the Osteoarthritic Hip,ondition for normal function in the hip joint is that the orientation of the WBS be horizontal (Fig. 50 p. 38). Only when this is the case are the component forces of . (. and .) and of . (. and .) equal and opposite. This is because force . is always resolved into vertical and horizontal components

Classification of Osteoarthritis of the Hip,type of OA he is deahng with. In our opinion the terms primary and secondary OA are inadequate and we think it more profitable to classify OA according to:.Thus a diseased hip has four characteristics, each of which may be further classified (Table 5).

Acetabuloplasty and Pelvic Osteotomy,if all the variables are normal, a slight inclination to the horizontal is enough to change the biomechanics in the hip. The change creates extra stress in the tissues and is responsible in the long run for their degeneration.

Pathogenesis of Superolateral Types d1) and d2) Osteoarthritis,type d) OA (classification: . 1979) (Fig. 312). This particular type of OA affects hips which originally were anatomically perfect and have allowed most of their owners to enjoy very active sports during their lives.
