“…It has been observed that intrauterine jaw movement begins after the formation of the articular disk in various species of mammals (rats: Copray et al 1988;mice: Narayanan et al 1971;humans: Petrikovsky et al 1999). It has been suggested that the process of prenatal joint development is based on the genetic program but can be modified as well by intrauterine movements (Strauss et al 1960;Mital & Millington 1971;Persson 1983;Wong et al 1985;Kihara et al 1998). Our recent study also demonstrated that prenatal jaw movement plays a role in condylar cartilage development (Habib et al 2005).…”

Previous studies suggest that jaw movement is an important factor in the development of cartilage in the temporomandibular joint during the prenatal and postnatal periods. In the present study, the effects of fetal jaw movement on the articular disk were studied in mice by restraining the opening movement of the mouth using the mouse exo utero development system. At embryonic day 18.5, the articular disk was reduced in size in the embryos whose maxilla and mandible were sutured (sutured group) and there were changes in the cellular morphology of the mesenchymal cells in the disk. The volume of the articular disk, the total number of cells and the number of 5-bromo-2'-deoxyuridine-positive cells in the articular disk were significantly lower in the sutured group than in the non-sutured control group. Our data revealed that fetal jaw movement affects the development of the articular disk in the temporomandibular joint.

“…5 controls, but did not form bundle-or sheet-like structures which were parallel to the joint surface as in the El 8.5 controls. Although a similar orientation of bundles parallel to the surface has also been reported in humans (Robinson and Cameron, 1956;Cameron and Robinson, 1958;Little et al, 1958), it has been controversial as to whether the orientation in the network structure of collagen fibers in the FH is guided by the compression and tension forces to which they are subject, or purely by genetic program (Zarek and Edwards, 1963;Sledge, 1968;Mital and Millington, 1971). The present study showed that the subsurface collagen fibers in the FH of the operated side did not form bundle-or sheet-like structures seen in controls and remained as a random meshwork which are normally observed in younger fetuses.…”

“…However, these experiments were only able to examine the disturbance of movements of the hind limbs as an etiology of dislocation of the hip during the post-weaning period, and the causes of dislocation of the hip during prenatal and weaning periods have remained unknown. Furthermore, the normal prenatal development of the joints has been argued to be driven either by genetic program alone or also modified by intrauterine movements (Mital and Millington, 1971;Persson, 1983). In our previous study (Kihara et al, 1998), we observed morphological maturation of the surface of the FH in human fetuses during mid gestation.…”

Effects of Restrained Fetal Movement on the Development of the Rat Hip Joint

The effect of fetal movement on the development of the hip joint was examined by restraining the leg movement using exo utero operation in rat fetuses. At embryonic day (E) 16.5, when the hip joint cavity starts to form, one side of the hind limb was sutured onto the embryonic membrane. After exo utero development to E18.5, the hip joint of the operated side was compared morphologically with those of the unoperated side, sham‐operated and unoperated in utero controls. The largest diameter of the femoral head (FH) and the gross morphology of the joint cavity of the operated side was not different from those of controls. By light microscopy (LM), the surface of the control E18.5 FH and acetabulum was smooth and covered by thin scale‐shaped cells which were partially pyknotic, and oval‐shaped cells underneath were rather regularly arranged in a thickness of a few cells. By transmission electron microscopy (TEM), scale‐shaped cells covered the FH surface incompletely, and the spaces in‐between were filled with the intercellular matrix. Oval‐shaped cells underneath had well developed rough endoplasmic reticulums. By scanning electron microscopy (SEM), mounds and grooves on the FH surface were evident at E17.0 but became unclear at E18.5. Subsurface collagen fibers formed a coarse meshwork at E17.0 but formed bundles at E18.5. On the operated side, by LM, the surface of the FH and acetabulum was irregular and lined by spindle‐shaped cells, whereas the underlying mesenchymal cells also showed an irregular cell shape and arrangement. By TEM, collagen fibrils in intercellular spaces were dense but did not generally form bundles. By SEM, the FH surface was rugged with banks and subsurface collagen fibers did not form bundles but remained as a dense meshwork. These results suggest that the fetal hind limb movement influences development of the surface structure of the FH and acetabulum and that this system may be useful to study prenatal etiology of the congenital dislocation of the hip.

“…To facilitate the incorporation of the pattern of collagen fibres in the surface zone (i.e. aligned towards the fossa of the acetabulum and femoral head ( Mital and Millington, 1970 ) ( Fig. 1 a)), the solid model of the cartilage was partitioned along the split-lines so that the meshed elements and fibres could be oriented along these directions ( Maas et al, 2012 ).…”

“…The fibre orientation in the surface zone of cartilage can be visualised by inserting a needle dipped in ink into the surface of cartilage and is sometimes referred to as the split-line pattern. In the healthy hip joint, fibres in the surface zone align towards the fossa of acetabulum and femoral head ( Mital and Millington, 1970 ), hypothesised to align with the directions of maximum principal tensile strain ( Bullough and Goodfellow, 1968 , Armstrong, 1986 ).…”

The aim of this study was to develop a finite element (FE) hip model with subject-specific geometry and biphasic cartilage properties. Different levels of detail in the representation of fibre reinforcement were considered to evaluate the feasibility to simplify the complex depth-dependent fibre pattern in the native hip joint. A FE model of a cadaveric hip with subject-specific geometry was constructed through micro-computed-tomography (µCT) imaging. The cartilage was assumed to be biphasic and fibre-reinforced with different levels of detail in the fibre representation. Simulations were performed for heel-strike, mid-stance and toe-off during walking and one-leg-stance over 1500 s. It was found that the required level of detail in fibre representation depends on the parameter of interest. The contact stress of the native hip joint could be realistically predicted by simplifying the fibre representation to being orthogonally reinforced across the whole thickness. To predict the fluid pressure, depth-dependent fibre organisation is needed but specific split-line pattern on the surface of cartilage is not necessary. Both depth-dependent and specific surface fibre orientations are required to simulate the strains.
