Conjoined Ischiopubic Rami Bones 13 The inferior ramus of the pubis unites with the ramus of the ischium on the medial side of the obturator foramen. The greater part of the pelvic surface of the ischium gives origin to the obturator internus. There is a bursa deep to the tendon. The upper border forms part of the margin of the obturator foramen. The lower area is subdivided by a longitudinal ridge into outer and inner area Fig. The dorsal surface of the ischium has the following relationships.
The upper and lower margins of the notch give origin to the superior and inferior gemelli respectively Fig. The attachments on the ischial tuberosity are as follows.
The notch is lined by hyaline cartilage. The upper convex area is related to the piriformis. The groove transmits the tendon of the obturator internus Fig. The conjoined rami have 1 two borders. The 7ower border forms the pubic arch along with the corresponding border of the bone of the opposite side. The pelvic surface is smooth and forms part of the lateral wall of the true pelvis.

The lesser sciatic notch is occupied by the tendon of the obturator internus. The site of union may be marked by a localized thickening. Its dorsal surface is crossed by the internal pudendal vessels and by the nerve to the obturator internus Figs 2. The superolateral area gives origin to the semimembranosus. The upper area gives origin to the obturator internus. The perineal membrane is attached to the lower ridge. The upper ridge gives attachment to the upper layer of the urogenital diaphragm.
The middle area gives origin to the sphincter urethrae and to the. It is large and oval in males. It is bridged by the transverse ligament. Ossification in the acetabulum is complete at years. The lower area provides attachment to the eras penis. These are i the iliac crest. At birth the hip bone is ossified except for three cartilaginous parts. It is closed by the obturator membrane which is attached to its margins. The ischiopubic rami fuse with each other at 7 to 8 years of age Fig.
It is a deep cup-shaped hemispherical cavity on the lateral aspect of the hip bone. The nonarticular roughened floor is called the acetabular fossa. The fibrocartilaginous acetabular labrum is attached to the margins of the acetabulum. This is a large gap in the hip bone. The primary centres appear.
A horseshoe-shaped articular surface or lunate surface is seen on the anterior. It contains a mass of fat which is lined by synovial membrane. The anterior superior iliac spine. It is lined with hyaline cartilage. Hj Bones 15 deep transverse perinei. The hip bone ossifies in cartilage from three primary centres and five secondary centres.
The secondary centres appear at puberty. It is directed laterally. The margin of the acetabulum is deficient inferiorly. The angle of femoral torsion or angle of ante. The anterior surface is flat. Blood supply. The angle facilitates movements of the hip joint. It is strengthened by a thickening of bone called the calcar femorale present along its concavity. The curvatures of the iliac crest are more pronounced in males. The vessels.
Like any other long bone it has two ends upper and lower.
This set constitutes the main supply and damage to it results in necrosis of the head following fractures of the neck of the femur. The articular cartilage of the head may extend to this surface. Only a little more than its medial half is intracapsular. This pit is called the fovea. The obturator foramen is large and oval in males. The intracapsular part of the neck is supplied by the retinacular arteries derived chiefly from the trochanteric anastomosis.
It connects the head with the shaft and is about 3. These arterial twigs enter the acetabular notch and then pass along the round ligament to reach the head Fig. The upper border.
It articulates with the acetabulum to form the hip joint. The posterior surface is convex from above downwards and concave from side to side. The head is directed medially upwards and slightly forwards. The pubic crest is shorter in males. The chilotic line extends from the iliopubic eminence to the iliac crest. It meets the shaft at the intertrochanteric crest. The neck has two borders and two surfaces. The lower border. It is entirely intracapsular. In females.
A roughened pit is situated just below and behind the centre of the head. These are described as follows. The upper end bears a rounded head whereas the lower end is widely expanded to form two large condyles.
It makes an angle with the shaft. It is less in females due to their wider pelvis. The head forms more than half a sphere. Upper End The upper end of the femur includes the head. The lower margin of the ischiopubic rami is more everted in males. The iliac fossa is deeper in males. Head 1. The shaft is directed obliquely downwards and medially so that the lower surfaces of the two condyles of the femur lie in the same horizontal plane.
The preauricular sulcus is more marked in females. It is crossed by a horizontal groove for the tendon of the obturator externus. The head is directed medially. The acetabulum is large in males.
After epiphyseal fusion. The cylindrical shaft is convex forwards. Neck 1. It is about 15 degrees. It meets the shaft at the intertrochanteric line. The apex is the inturned posterior part of the posterior border. The upper border of the trochanter lies at the towards the head. The extracapsular part of the 2. This is large quadrangular prominence located fossa below.
The medial surface presents a rough impression above. The anterior surface is rough ln its a Greater Trochanter l teral part. The lateral surface is crossed by an at the upper part of the junction of the neck with the oblique ridge directed downwards and forwards. The greater trochanter has an upper border neck is supplied by the ascending branch of the with an apex. The part of the surface over the lateral condyle is short and straight anteroposteriorly.
In the middle one-third. The patellar surface covers the anterior surfaces of both condyles. Lesser Trochanter It is a conical eminence directed medially and backwards from the junction of the posteroinferior part of the neck with the shaft.
The medial border and medial supracondylar line meet inferiorly to obliterate the medial surface. It is a smooth-rounded ridge. Between the two condyles. Articular Surface The shaft is more or less cylindrical.
It is narrowest in the middle. Intertrochanteric Line It marks the junction of the anterior surface of the neck with the shaft of the femur. It is separated from the tibial surfaces by two faint grooves. It is convex forwards and is directed obliquely downwards and medially. The medial and lateral surfaces are directed more backwards than towards the sides.
Intertrochanteric Crest It marks the junction of the posterior surface of the neck with the shaft of the femur. In the lower one-third of the shaft also. The spiral line winds round the shaft below the lesser trochanter to reach the posterior surface of the shaft Fig. The linea aspera has distinct medial and lateral lips.
The rounded elevation. Shaft In the upper one-third of the shaft. The gluteal tuberosity is a broad roughened ridge on the lateral part of the posterior surface. Lower End The lower end of the femur is widely expanded to form two large condyles. The medial and lateral borders are rounded and ill-defined. It is a prominent roughened ridge which begins above. The tibial surfaces cover the inferior and posterior surfaces of the two condyles.
The two condyles are partially covered by a large articular surface which is divisible into patellar and tibial parts. The part over the medial condyle.
Thus it has four borders. It has a deeper anterior part and a shallower posterior part. The most prominent point on it is called the medial epicondyle.
The lateral aspect presents the following. Intercondylar Fossa or Intercondylar Notch This notch separates the lower and posterior parts of the two condyles. The attachments on the shaft are as follows. Posterosuperior to the epicondyle there is a projection. This tubercle is an important landmark. It is limited anteriorly by the patellar articular surface. Though it is less prominent than the medial condyle. The attachments on the lesser trochanter are as follows.
Lateral Condyle The lateral condyle is flat laterally. The trochanteric bursa of the gluteus medius lies in front of the ridge. The intertrochanteric line provides: The fovea on the head of the femur provides attachment to the ligament of the head of femur or round ligament.
The quadrate tubercle receives the insertion of the quadratus femoris Fig. The following are attached to the greater trochanter. The epiphyseal line for the lower end of the femur passes through it. The origin of the medial head of the gastrocnemius extends to the popliteal surface just above the medial condyle. They separate the extensor muscles from the adductors medially. When the knee is flexed the tendon of this muscle lies in the shallow posterior part of the groove.
The attachments on the lateral condyle are as follows. In case it is absent. The infrapatellar synovial fold is attached to the anterior border of the intercondylar fossa. The intercondylar line provides attachment to the capsular ligament and laterally to the oblique popliteal ligament. The following points are noteworthy. The attachments on the medial condyle are as follows. The primary centre for the shaft appears in the seventh week of intrauterine life. Nutrient Artery to the Femur This is derived from the second perforating artery.
The attachments on the intercondylar notch are as follows. There are three epiphyses at the upper end and one epiphysis at the lower end. The posterior cruciate ligament is attached to the anterior part of the lateral surface of the medial condyle. The upper epiphyses. The lower epiphysis fuses by the twentieth year. The nutrient foramen is located on the medial side of the linea aspera.
The femur ossifies from one primary and four secondary centres. The secondary centres appear. It is covered by an expansion frorr the tendon of the rectus femoris.
The posterioi surface is articular in its upper three-fourths and non-articular in its lower onefourth. The apex directed downwards. Another vertical ridge separates a medial strip from the medial portion.
This mechanism helps in resisting stresses including that of body weight. The bone laid on a table rests on th broad lateral area. Structure The angles and curvatures of the femur are strengthened on their concave sides by bony buttresses. The posterior articular surface is divided by. The anterior surface is rough and non-articulai The upper three-fourths of the posterior surface ar smooth and articular.
The apex is non-articula posteriorly. This strip articulates with a reciprocal strip on the medial side of the intercondylar notch of the femur during full flexion. The rest of the medial portion and the lateral portion of the articular surface are divided by two transverse lines into three pairs of facets. The concavity of the neck-shaft angle is strengthened by a thickened buttress of compact bone.
The patella is triangular in shape with its ape directed downwards. Presence of its centre in a newly born child found dead indicates that the child was viable. The articular area is divided by a vertical ridge into a larger lateral and smaller medial portion. In addition. Tripping over minor obstructions or other accidents causing forced medial rotation of the thigh and leg during the fall results in: Ossification of femur. Features The patella has an apex. The articular surface has a raised medial margin which covers the 1.
The upper end includes: The lateral borderprovides insertion to vastus lateralis in its upper one-third or half. One or two centres at the superolateral angle of the patella may form separate pieces of bone.
Medial Condyle Medial condyle is larger than the lateral condyle. The condition is bilateral and symmetrical Fig. The medial side of the lower end projects downwards beyond the rest of the bone. Features The tibia has an upper end.
The posterior surface of the medial condyle has a groove. Its superior surface articulates with the medial condyle of the femur. The lateral margin of the articular surface is raised to cover the medial intercondylar tubercle. It is sinuously curved and terminates below at the anterior border of the medial malleolus. This is prevented by 1 bony factor—the lateral edge of the patellar articular surface of the femur is deeper than the medial edge Fig. The anterior border of the shaft is most prominent and crest-like.
The peripheral part is flat and is separated from the femoral condyle by the medial meniscus. Fracture of the patella should be differentiated from a bipartite or a tripartite patella Fig. The non-articular area on the posterior surface provides attachment to the ligamentum patellae below. The articular surface is oval and its long axis is anteroposterior.
The medial borderprovides insertion to the vastus medialis in its upper two-thirds or more. The anterior and medial surfaces are marked by numerous vascular foramina. The upper end is much larger than the lower end.
As in the case of the medial condyle. Such a patella is known as bipartite or tripartite patella. It is homologous with the radius of the upper limb. The articular surface is nearly circular. The patella probably improves the leverage of the quadriceps femoris by increasing the angulation of the line of pull on the leg.
The central part of the surface is slightly concave and comes into direct contact with the femoral condyle. Fusion is complete at puberty. The superior surface of the condyle articulates with the lateral condyle of the femur.
The patella ossifies from several centres which appear during 3 to 6 years of age. Lateral Condyle The lateral condyle overhangs the shaft more than the medial condyle.
Attachments on the Patella The superior border or base provides insertion to the rectus femoris in front and to the vastus intermedius behind. The projection is called the medial malleolus. Upper End The upper end of the tibia is markedly expanded from side to side.
The lower pair of articular facets articulates during extension. During different phases of movements of the knee. The patella has a natural tendency to dislocate outwards because of the outward angulation between the long axes of the thigh and leg. It is widest in its upper pa This part is crossed obliquely by a rough ridge calL the soleal line.
The medial border is rounded. Lower End The lower end of the tibia is slightly expanded. The interosseous or lateral border extends from the lateral condyle a little below and in front of the fibular facet.
Above the soleal line. The lower part is smooth and may be covered with hyaline cartilage. Attachments on the Medial Condyle a The semimembranosus is inserted into the groove on the posterior surface. The medial malleolus is a short but strong process which projects downwards from the medial surface of the lower end of the tibia.
Borders The anterior border is sharp and S-shaped being convex medially in the upper part and convex laterally in the lower part. The medial surface is subcutaneous and is continuous with the medial surface of the medial malleolus. It is divided into medial and laten parts by a vertical ridge. Surfaces The lateral surface lies between the anterior and interosseous borders. It has five surfaces. It has three borders. The lateral aspect of the lower end presents a triangular fibular notch to which the lower end of the fibula is attached.
Medially the articular surface extends on to the medial malleolus. The upper part of the notch is rough.
It is subcutaneous and forms the shin. The posterior surface lies between the medial ai interosseous borders. The inferior surface of the lower end is articular. A nutrient foramen i situated near the upper end of this ridge. It extends from the tibial tuberosity above to the anterior border of the medial malleolus below. It forms a subcutaneous prominence on the medial side of the ankle. It extends from the medial condyle.
The area below the sole. The medial surface lies between the anterior and medial borders. It articulates with the superior trochlear surface of the talus and thus takes part in forming the ankle joint. The soleal line begins just behind tl fibular facet.
The anterior surface of the lower end has an upper smooth part. It is broad. In its upper three-fourths. Shaft The shaft of the tibia is prismoid in shape. It i directed downwards and transmits the nutrient arter which is a branch of the posterior tibial artery. The lower rough area of the tuberosity is subcutaneous.
Mmmmmmmmmmmmmm e The posterior horn of the medial meniscus. Attachment on Tibial Tuberosity The ligamentum patellae is attached to the upper smooth part of the tibial tuberosity.
