“…The relative contributions of these soft tissue structures to biomechanical joint stability in distraction, however, are poorly understood. 12,13 The proximal hip capsule is a thick, substantial structure that includes the zona orbicularis, a structure that is easily visualized from within the capsule and used as a landmark in arthroscopic surgery. 14 Its function, however, is poorly understood.…”

“…18 These complexes do not constitute the entire capsule and have ill-defined borders. 13,18 The iliofemoral and ischiofemoral ligaments appear the most important for hip stability. 19 Again, because these ligaments connect the pelvis to the femur, these structures or the capsule in its entirety may provide stability to the hip joint in distraction.…”

ABSTRACT:The structure and function of the proximal hip joint capsule and the zona orbicularis are poorly understood. We hypothesized that the zona orbicularis is an important contributor to hip stability in distraction. In seven cadaveric hip specimens from seven male donors we distracted the femur from the acetabulum in a direction parallel to the femoral shaft with the hip in the neutral position. Eight sequential conditions were assessed: (1) intact specimen (muscle and skin removed), (2) capsule vented, (3) incised iliofemoral ligament, (4) circumferentially incised capsule, (5) partially resected capsule (distal to the zona orbicularis), (6) completely resected capsule, (7) radially incised labrum, and (8) completely resected labrum. The reduction of the distraction load was greatest between the partially resected capsule phase and completely resected capsule phase at 1, 3, and 5 mm joint distraction (p ¼ 0.018). The proximal to middle part of the capsule, which includes the zona orbicularis, appears grossly and biomechanically to act as a locking ring wrapping around the neck of the femur and is a key structure for hip stability in distraction. ß

“…The solid phase is considered as homogenous, isotropic, porous, and linearly elastic, while the liquid phase is considered to be non-viscose. The ligaments were modeled as non-linear, homogenous material; the material properties of which were taken from the literature [3,10].…”

Osteoarthritis (OA) can be used as a common name for a group of overlapping pathological conditions when the balance between the processes of degradation and synthesis, in individual parts of the cartilage, is disturbed and leads to gradual cartilage destruction. A preventive approach toward OA helps with a timely diagnosis and subsequent treatment of this disease. One of the significant risk factors affecting development of hip joint OA is the mechanism and magnitude of mechanical loading on the joint. The main motivation for this work was to verify the hypothesis involving a pathologic cycle (overloading - change of locomotion - overloading) as contributory to the development of OA and whether it can be stopped, or at least partly decelerated, by a suitable change of movement stereotypes. Providing that there is a natural balance of muscular action, from the beginning of OA, the development of OA can be significantly decelerated. The return to a natural force balance can be achieved using suitable exercise and strengthening of muscular structures. In order to verify the hypothesis, we undertook experimental measurements of gait kinematics and a computational analysis of the hip joint using the Finite Element Method.
