[The anatomicofunctional characteristics of the hip joint]

32 femurs and 23 cotyloid cavities of people who died in accidents and also 29 locked hip joints of just-received cadavers of patients died from somatic diseases were studied by macroscopic methods. The results confirmed that femur head is being nourished from the obturator artery basin. Shape and other parameters of ligament of the costal head so as its possible absence in the hip joint were found to result from interrelations between cotyloid cavity and head of the femur. Ligament of the costal head is maximally strained in extreme femur adduction and in all other positions it is more or less relaxed. This indicates the lack of essential mechanical role of ligament of costal head in hip joint biomechanics. The data obtained substantiate the possibility of using the ligament as a nutritive vascular peduncle of an osteochondral autograft, excised from lower internal region of femur head.
