“…Growth of the femoral head and the acetabulum appears to maintain a mutually dependent relationship in the formation of a congruent hip [32]. The acetabulum seems to require a spherical femoral head as a template for spherical growth [16]. Conversely, the development of a spherical femoral head seems to require a critical minimal amount of acetabular coverage.…”

Structural deformities of the femoral head occurring during skeletal development (eg, Legg-Calvé-Perthes disease) are associated with individual shapes of the acetabulum but it is unclear whether differences in acetabular shape are associated with differences in proximal femoral shape. We questioned whether the amount of acetabular coverage influences femoral morphology. We retrospectively compared the proximal femoral anatomy of 50 selected patients (50 hips) with developmental dysplasia of the hip (lateral center-edge angle [LCE] B 25°; acetabular index C 14°) with 45 selected patients (50 hips) with a deep acetabulum (LCE C 39°). Using MRI arthrography we measured head sphericity, epiphyseal shape, epiphyseal extension, and femoral head-neck offset. A deep acetabulum was associated with a more spherical head shape, increased epiphyseal height with a pronounced extension of the epiphysis towards the femoral neck, and an increased offset. In contrast, dysplastic hips showed an elliptical femoral head, decreased epiphyseal height with a less pronounced extension of the epiphysis, and decreased head-neck offset. Hips with different acetabular coverage are associated with different proximal femoral anatomy. A nonspherical head in dysplastic hips could lead to joint incongruity after an acetabular reorientation procedure.

“…Acetabular and femoral abnormalities are often combined because the final acetabular shape and depth depends on the interaction with a spherical femoral head [16]. For example, hips with Legg-Calvé-Perthes disease or proximal femoral focal deficiency have a higher incidence of dysplasia, acetabular retroversion, and incongruity [4][5][6].…”

“…The development of the hip in humans is a particularly well documented process. Cavitation occurs around the 7th week of gestation, and in the subsequent 4 weeks the predominant forms of the spherical femoral head, short femoral neck, and primitive greater trochanter become apparent (60). It is evident that specific patterns of differentiation and growth provide the means of such morphogenetic changes.…”

Bioengineering Cartilage Growth, Maturation, and Form

Cartilage of articular joints grows and matures to achieve characteristic sizes, forms, and functional properties. Through these processes, the tissue not only serves as a template for bone growth but also yields mature articular cartilage providing joints with a low-friction, wear-resistant bearing material. The study of cartilage growth and maturation is a focus of both cartilage biologists and bioengineers with one goal of trying to create biologic tissue substitutes for the repair of damaged joints. Experimental approaches both in vivo and in vitro are being used to better understand the mechanisms and regulation of growth and maturation processes. This knowledge may facilitate the controlled manipulation of cartilage size, shape, and maturity to meet the criteria needed for successful clinical applications. Mathematical models are also useful tools for quantitatively describing the dynamically changing composition, structure and function of cartilage during growth and maturation and may aid the development of tissue engineering solutions. Recent advances in methods of cartilage formation and culture which control the size, shape, and maturity of these tissues are numerous and provide contrast to the physiologic development of cartilage.

Objective: To analyze the features of coverage of femoral head at weight-bearing interface of the hip joints in children. Material and Methods: MRI scans of the hips were performed in 95 normal children aged from 1 to 8 years. Radial scans of the hip joints were performed using FFE sequence. Review the morphological features of weight-bearing interface of the acetabulum and the femoral head. Total covering angle (TCA), acetabular covering angle (ACA) and labral covering angle (LCA) were measured, inter-group comparison and correlation analysis were done. Result: The acetabulum and the femoral head had congruent articulating surface at each weight-bearing position. There was no statistical TCA difference at each position. Average ACA increased, while average LCA decreased from anterior to posterior. TCA correlated with LCA, ACA negatively correlated with LCA. Conclusion: TCA is a good index in indicating stability of the hip joint. Cartilage ossifies slower at posterior than anterior positions. Cartilage acetabulum and the labrum serve as complementary structures that contribute in total stabilizing of the hip joint in development.
