biomechanics of hip joint wikipedia

Limb formation begins by the fourth week of the embryonic life. A recent study found no significant vascular contribution by the foveal artery. Proc R Soc Med. The acetabular cartilage complex, which is composed mainly of hyaline cartilage, forms the cup-shaped articular portion of the acetabulum. NIH Overall, the lateral femoral circumflex artery contributes little to the vascularity of the femoral head. Subscribe for more lectures https://www.youtube.com/user/OrthopaedicPrinciple The triradiate cartilage forms the nonarticular medial wall of the acetabulum, and its growth is crucial for acetabular height and depth. On a cadaveric study of 154 hips, the mean values for the acetabular depth and diameter were 29.49 ± 4.2 mm and 54.29 ± 3.8 mm, respectively. An anterior branch of the posterior division of the obturator artery provides the blood supply to the ligamentum teres ( Fig. PMCID: PMC1901095 Although the function of the ligamentum teres has yet to be determined, its role as a source of hip pain after a full or a partial tear has been more clearly elucidated. They chose to illustrate the capsular innervation arrangement by depicting the capsule as the face of a clock. Figure 1: Structure of the hip joint. It is an encapsulated synovial joint with a ball and socket architecture in which the femoral head is the ball and the acetabulum is the socket. Trabecular pattern. The most inferomedial aspect of the insertional footprint extends to within a few millimeters of the acetabular rim. A retroverted acetabulum occurs when the acetabulum is angled less than 15 degrees anteriorly. (From Gardner MJ, Robertson WJ, Boraiah S, et al: Anatomy of the greater trochanteric “bald spot”: a potential portal for abductor sparing femoral nailing? The femoral nerve travels with (and lateral to) the femoral artery and vein. Petersen et al. The muscle forces acting on the trochanter apophysis can be combined as a trochanteric resultant RT. Cross-sectional histology of the labrum: The labrum is separated from the articular cartilage by a physiological cleft (. This must be accomplished while allowing for dynamic loading during activities such as gait and balance. The calcar femorale was precisely defined anatomically by Merkle in 1874 as a dense plate of bone extending laterally from the posteromedial femoral cortex to the posterior aspect of the greater trochanter. Song et al. Paul JP. HHS The medial arm passes almost vertically inferior and inserts on a subtle angulated prominence of the anterior-inferior femur, at the level of the lesser trochanter, with a circular-shaped footprint. Previous. Alternatively, Gerhardt et al. The main vascular supply of the labrum arises from radial vessels on its capsular side embedded in a loose connective tissue between the labrum and the capsule ( Fig. The inner fibers comprise the zona orbicularis, which forms a collar around the femoral neck. The ligamentum teres has been found to be taut in flexion, adduction, and external rotation, and thus it may play a role in stability of the hip joint in those positions. The second line that composes the alpha angle is from the center of the femoral head to a point where the femoral head loses its sphericity, and thus where femoral head exceeds the normal radius of the femoral head. In a recent study, Domb et al. At birth the ossification of the femoral shaft reaches the greater trochanter and the femoral neck. One theory regarding the spiral architecture of the capsule is that it originated as humans began to walk upright. Joint Biomechanics Definitions. Medially, it is attached to either side of the acetabular notch by two bands that originate from the acetabular transverse ligament and the pubic and ischial margins. The sacroiliac joint is the largest axial joint in the body, with an average surface area of 17.5cm 2. In normal stance, if the upper body is leaned slightly posteriorly, stability is provided primarily by the static restraints of the anterior capsule (mainly the iliofemoral ligament). Those ossification centers have an important role in the development of the acetabular rim and its depth. The pubofemoral ligament (PFL) originates on the iliopectineal eminence of the superior pubic ramus with a triangle-shaped insertional footprint ( Fig. Oper Orthop Traumatol. The sealing function of the labrum also helps maintain the negative intraarticular pressure that occurs in all joints. It courses along the iliacus muscle and alongside the psoas, descends under the inguinal ligament, innervates the anterior thigh musculature, and provides cutaneous innervation to the lower leg through its terminal branch of the saphenous nerve. The three main groups of retinacular vessels—superior, inferior, and anterior—are all intracapsular and covered with a synovial membrane, sometimes in a mesenteric-like fold of synovial membrane. In some cases it was found to be anastomosing with the epiphyseal arteries, whereas in other cases it was found to supply only the area of insertion of the ligamentum teres to the fovea. Ferguson et al. DOI link for Biomechanics of the Hip Joint. The acetabulum has two components: the triradiate cartilage in the center ( Fig. in the hip, it is the result of the need to balance the moment arms of the body weight and abductor tension. This stimulates a lateral-cranial growth of the trochanter apophysis. It is a study of the performance and function of biomaterials used for orthopedic implants. The zona orbicularis has leashlike fibers organized in a spiral configuration; together with the anterior capsular ligaments, they tighten in a “screw home” mechanism during terminal extension and external rotation, further stabilizing the joint. Clinically, increased femoral anteversion can be seen as an “in-toed” appearance of the lower limb in a standing person, or squinting patellae, where the patellae point toward the midline. The labrum deepens the acetabulum and acts as a suction seal, adding stability to the joint and protecting the articular cartilage. Ligamentous relationships of the hip capsule. Because the proximal femur is exposed to tensile and compressive forces during weight bearing, those forces lead to functional internal bony architecture of the femoral neck trabeculae lines as stated by Wolff’s law of bone remodeling. This negative intraarticular pressure helps resist distraction of the femoral head from the socket; this function is called the “suction effect” and is thought to improve the stability of the joint. looked at the labrum under light microscopy and found that the majority of the collagen fibers have a circumferential orientation. The hip is a complex anatomic structure composed of osseous, ligamentous, and muscular structures responsible for transferring the weight of the body from the axial skeleton into the lower extremities. This internervous plane, which is poorly innervated, was named the “safe zone” of the capsule ( Fig. Normal average anteversion ranges between 35 and 45 degrees at the time of birth, is 31 degrees at the age of 1 year, and decreases to 15.4 degrees by skeletal maturity (16 years of age). The nerve courses laterally through the pelvis, exits at the greater sciatic foramen, and travels distally deep to the piriformis and superficially to the short external rotators. 1990 Mar;30(3):135-40. These two segments form a diarthrodial ball-and- socket joint with three degrees of freedom: flexion/extension in the sagittal plane, abduction/adduction in the frontal plane, and Medial/lateral rotation in the transverse plane. The load of the hip joint is related to the density of bone, thickness of cartilage and pattern of the cancellous bone. As the structural linkage between the axial skeleton and lower limbs, it plays a pivotal role in transmitting forces from the ground up and carrying forces from the trunk, head, neck and upper limbs down. An anteroposterior radiograph of the hip illustrating the primary and secondary compressive and tensile trabecular bone groups. Values of maximal joint pressure (maximal joint reaction force applied: 400% bodyweight) reached 8–10 MPa. 79-7 ). The neck shaft angle is the angle measured between the axis of the femoral neck and the femoral shaft. 2004 Nov;33(11):1259-66. doi: 10.1007/s00132-004-0719-z. Based on the data derived from the examination of 16 infantile and juvenile anatomical hip specimens as well as the radiological examination of 1350 hip joints of healthy children, a biomechanical model of the developing hip was computed. As life progresses, these bones fuse together in a fashion that makes them more uniform with time. Ligamentum teres. These growth plates are essential for the growth and shape of the proximal femur. The hip joint is a synovial joint formed by the articulation of the rounded head of the femur and a cup-like acetabulum of the pelvis. It could be proven that the apophysis of the greater trochanter is subject to compressive stress by lateral-cranial traction bands and therefore corresponds with a "pressure apophysis". The single proximal insertion abuts the anterior inferior iliac spine, wrapping around the base like a crescent, and extends within a few millimeters of the acetabular rim along the anterior and anterolateral acetabulum. The nerve to the quadratus femoris is a sacral plexus nerve that arises from L4 to S1 and leaves the pelvis through the greater sciatic foramen. Medially it is in continuation with the lower border of the femoral neck, laterally with the intertrochanteric crest, and inferiorly with the linea aspera. The proximal femur is supplied by three main blood sources: (1) the nutrient artery of the shaft that arises from the perforating arteries; (2) the retinacular vessels of the capsule that arise from the circumflex arteries; and (3) the foveal artery of the ligamentum teres. The biomechanical role of the ligamentum teres has been debated in the medical literature since the nineteenth century, with proposed functions including that of a stabilizer, a fluid and force distributor in the acetabulum, and an embryonic remnant with no specific role in adults. The alpha angle was described by Notzli et al. The femoral nerve is formed by the L2 to L4 nerve roots in the lumbar plexus. In science, biomechanics is the study of forces acting on a living body. The articular cartilage of the hip, both on the acetabular side and the femoral side, has been shown to be highly inhomogeneous in thickness distribution. In the past the accessory obturator nerve has been described as being present in between 10% and 30% of people. By the eight week, the capsule, the acetabular labrum, the ligamentum teres, and the transverse ligament can be identified microscopically, and 3 weeks later they can be identified macroscopically. Its branches to the capsule supply the quadratus femoris posteroinferiorly and enter it predominantly medially and occasionally laterally over an arc of 105 degrees between half past 6 and 10 o’clock. Murtha et al. have found a contribution to capsular innervation from the inferior gluteal nerve in only two specimens (10%), and noted that the nerve entered the capsule laterally at 8 o’clock. Additionally, the zona orbicularis may limit distraction of the femoral head from the acetabulum. romF. (From Petersen W, Petersen F, Tillmann B: Structure and vascularization of the acetabular labrum with regard to the pathogenesis and healing of labral lesions. in: Operat Orthop Traumatol 1997;9:1-15 (Heft 1). (From Hughes PE, Hsu JC, Matava MJ: Hip anatomy and biomechanics in the athlete. have shown that the labrum increases the acetabular surface area and volume by 22% and 33%, respectively. Enjoy the videos and music you love, upload original content, and share it all with friends, family, and the world on YouTube. The medial circumflex femoral artery supplies blood to the neck of the femur and femoral head. Although its structure may seem simple, it is actually very complicated with more than 20 muscles spanning the joint and a three-dimensional (3D) bony morphology that may vary widely among subjects. In addition, no differences in number or type of nerves and organs were found based on the age of the specimens, but more unmyelinated nerve endings, which function to sense pain, were identified in the superior and anterior quarters of the labrum. Anatomy & Biomechanics of the Hip Damien P. Byrne*, Kevin J. Mulhall and Joseph F. Baker Orthopaedic Research and Innovation Foundation, Sports Surgery Clinic, Santry, Dublin, Ireland Abstract: The hip joint is unique anatomically, physiologically, and developmentally; therefore understanding the basic Another reported measure of acetabular depth can be determined from axial magnetic resonance or CT views of the hip joint as the distance between the center of the femoral head and the line connecting the anterior acetabular rim to the posterior acetabular rim. A greater trochanteric group completes the pattern of trabecular orientation. [Article in German] Polster J(1). Additionally, cranial retroversion may be present, in which the anterior acetabular wall crosses over the posterior wall only superiorly (demonstrating a positive “cross-over sign” on radiographs). The offset is the difference between the anterior contour of the head and femoral neck on axial MRI or CT scans. Although currently somewhat a matter of controversy, the normal values of the center edge angle are between 25 and 35 degrees. It is triangular in its cross-sectional shape, with its base attached to the acetabulum and its apex forming a free edge ( Fig. Originating at the sacral plexus from the L4 to S1 sacral nerves, the superior gluteal nerve leaves the pelvis through the greater sciatic foramen above the piriformis, accompanied by the superior gluteal artery and the superior gluteal vein. Please enable it to take advantage of the complete set of features! Furthermore, the labrum creates a seal that opposes the flow of synovial fluid in and out of the central compartment. The capsular side of the labrum is composed of dense connective tissue mainly consisting of collagen types I and III, whereas the articular side is composed of fibrocartilage. Histologically, the acetabular labrum merges with the articular hyaline cartilage of the joint surface of the acetabulum through a transition zone of 1 to 2 mm, particularly anteriorly. USA.gov. Discussion: Exact knowledge about development, anatomy and biomechanics of hip joint has been a topic of interest and debate in literature dating back to at least middle of 18 th century, as Hip joint is liable for several number of pediatric and adult disorders. Biomechanics of hip joint: a review. 1. Seldes et al. The labrum has been shown to be richly populated by many neurologic structures. The superior group, which runs in the lateral retinacular fold, is larger, supplies the weight-bearing part of the femoral head, and may be the sole blood supply to the epiphysis. It is important to know and understand the basics of biomechanics of hip joint to define the movement of hip joint along with its load carrying capacity in different day to day activities. The retinacular vessels penetrate the capsule near its distal attachment and are the main blood supply to the femoral epiphysis and femoral head at all ages. found that the superior gluteal nerve branches to the capsule are small and have a leash of vessels; they cross the superior and posterolateral aspects of the capsule and enter it medially or more commonly laterally over an arc of 75 degrees between half past 10 and 1 o’clock. Complete absence of the proximal femur yields an absent acetabulum. This two-dimensional vector model describes the forces acting … A center edge angle of 20 to 25 degrees is often considered “borderline dysplasia,” whereas the upper limits of the center edge angle may be reported as up to 40 degrees. Seldes et al. Basic Biomechanics of the Hip D E Lunn, A Lampropoulos, T D Stewart Corresponding Author: Dr David E Lunn. Cycling Bio-mechanics and the Hip . found it in only 1 of 20 hips (5%), where it crossed the anteroinferior margin of the capsule and entered it medially over an arc of 15 degrees between half past 5 and 6 o’clock. also studied the labrum histologically and found it to be widest in its inferior half and thickest at its superior half. At the same time a shallow acetabulum begins to form proximal to the femoral head by the future ilium, ischium, and pubis precursor cells. The effective loading of the joint Based on the data derived from the examination of 16 infantile and juvenile anatomical hip specimens as well as the radiological examination of 1350 hip joints of healthy children, a biomechanical model of the developing hip was computed. Inferiorly, the labrum appears to be continuous with the transverse acetabular ligament over the cotyloid notch; however, a distinction is seen between the labrum and the transverse ligament. Those facets are the insertions of the abductor complex; the gluteus medius muscle attaches to the superoposterior and lateral facets, and the gluteus minimus muscle attaches to the anterior facet. It is an encapsulated synovial joint with a ball and socket architecture in which the femoral head is the ball and the acetabulum is the socket. The ILFL restricts external rotation in both flexion and extension and internal rotation in flexion. examined 11 formalin-mounted human hips and described a separation between the anterior innervation of the capsule (obturator and femoral nerve) and its posterior innervation (sciatic nerve, superior gluteal nerve, and the nerve to the quadratus femoris). Since the loading of the hip in the single leg stance phase of gait is a multiple of body weight, increases in body weight will have a particularly deleterious effect on the total compressive forces applied to the joint. Saudi Journal of Sports Medicine, 13(2), pp. Although the hip is a relatively mobile joint, it is also incredibly stable because of its osseous architecture, joint articulation, and extensive surrounding soft tissue structures. J Pediatr Orthop. The capsular branches of the obturator nerve travel along the anteroinferior margin of the capsule, entering the capsule primarily medially over an arc of 105 degrees between 3 o’clock and half past 6 o’clock, with an equal contribution from both the anterior and posterior branches. The foveal artery, running within the ligamentum teres, is formed by the acetabular branches of the obturator or the medial circumflex or from both, and often its contribution to the femoral head blood supply is minute. The superior and inferior retinacular vessels arise from the deep branch medial femoral circumflex artery and run along the upper and lower borders of the femoral neck. ... Plica syndrome is a disorder in which the synovial plica becomes inflamed and causes abnormal biomechanics in the knee. Through the twentieth week of gestation, the differentiation of the hip joint ends and the process shifts to growth and maturation. Click here to navigate to parent product. On average, the acetabular labral size ranges from 4 to 8 mm. Biotribology is a very important part of it. It forms the primary connection between the bones of … The hip joint ( coxa in Latin) is the articulation connecting the pelvis and the femur. Overall, the development of both the proximal femur and the acetabulum are related to correct development and positioning of each other. The capsule is generally thought to receive its innervation from branches of the obturator, femoral, sciatic, and superior gluteal nerves, the nerve to quadratus femoris, and possibly from the accessory obturator nerve. The medial cortex is also known as Adam’s arch. The acetabular depth can be also quantified radiographically on an anteroposterior pelvis view by the center edge angle (of Wiberg). Anastomoses of the deep branch of the medial femoral circumflex artery with other arteries have been described; a significant and consistent anastomosis with a branch of the inferior gluteal artery is found along the piriformis, and in some cases the inferior gluteal artery was found to be the main blood supply of the hip. Maximum cartilage thickness was found ventrosuperiorly in the acetabulum and in the femoral head. However, Birnbaum et al. The value is positive if the center of the femoral neck is lateral to the line connecting the acetabular rim and negative if medial to it. The capsular branches of the femoral nerve, which travel along the anterior margin of the capsule, pierce the capsule either medially or laterally over an arc of 75 degrees between the half-past 2- and 5-o’clock positions. Joint reaction force defined as force generated within a joint in response to forces acting on the joint. The ligamentum teres, otherwise known as the round ligament of the femur, is a triangular double-band ligament with a length of 30 to 35 mm that attaches the femoral head to the acetabulum. A description of the movements and forces acting around the hip joint that are expected during activities of daily living is offered and also how these movements are affected following total hip replacement, with particular reference to femoral offset and leg length inequality.
