Just scroll below to get the Download. The book has received numerous updates since it was first launched, creating a new volume every time it is updated. New images and texts are added, however, the basic content has somehow been unchanged. You can always opt for other books, but in India, even the top colleges follow it. There must be a reason for it, right? Suggestions to those studying anatomy in first year of MBBS includes following:.

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 medial surface presents a rough impression above. It is convex forwards and is directed obliquely downwards and medially. In the middle one-third. Between the two condyles. The spiral line winds round the shaft below the lesser trochanter to reach the posterior surface of the shaft Fig.

The medial and lateral borders are rounded and ill-defined. The rounded elevation. Lower End The lower end of the femur is widely expanded to form two large condyles. The part over the medial condyle. Intertrochanteric Crest It marks the junction of the posterior surface of the neck with the shaft of the femur. The medial and lateral surfaces are directed more backwards than towards the sides.

Shaft In the upper one-third of the shaft. It is narrowest in the middle. In the lower one-third of the shaft also. The linea aspera has distinct medial and lateral lips.

It is a prominent roughened ridge which begins above. Thus it has four borders. 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 patellar surface covers the anterior surfaces of both condyles. The gluteal tuberosity is a broad roughened ridge on the lateral part of the posterior surface. The medial border and medial supracondylar line meet inferiorly to obliterate the medial surface.

The tibial surfaces cover the inferior and posterior surfaces of the two condyles. It is a smooth-rounded ridge. It is separated from the tibial surfaces by two faint grooves. Intertrochanteric Line It marks the junction of the anterior surface of the neck with the shaft of the femur.

The part of the surface over the lateral condyle is short and straight anteroposteriorly. Articular Surface The shaft is more or less cylindrical. The two condyles are partially covered by a large articular surface which is divisible into patellar and tibial parts.

The attachments on the lesser trochanter are as follows. The attachments on the shaft are as follows. The following are attached to the greater trochanter. The most prominent point on it is called the medial epicondyle.

Though it is less prominent than the medial condyle. It has a deeper anterior part and a shallower posterior part. 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. This tubercle is an important landmark.

The quadrate tubercle receives the insertion of the quadratus femoris Fig. Posterosuperior to the epicondyle there is a projection.

It is limited anteriorly by the patellar articular surface. They separate the extensor muscles from the adductors medially.

Human Anatomy, Volume 2: Lower Limb, Abdomen and Pelvis

When the knee is flexed the tendon of this muscle lies in the shallow posterior part of the groove. The origin of the medial head of the gastrocnemius extends to the popliteal surface just above the medial condyle.

The attachments on the lateral condyle are as follows. The intercondylar line provides attachment to the capsular ligament and laterally to the oblique popliteal ligament. The upper epiphyses. The lower epiphysis fuses by the twentieth year. The following points are noteworthy. The attachments on the medial condyle are as follows. There are three epiphyses at the upper end and one epiphysis at the lower end.

The femur ossifies from one primary and four secondary centres. The posterior cruciate ligament is attached to the anterior part of the lateral surface of the medial condyle.

The secondary centres appear. The infrapatellar synovial fold is attached to the anterior border of the intercondylar fossa. The attachments on the intercondylar notch are as follows. The nutrient foramen is located on the medial side of the linea aspera. In case it is absent. Nutrient Artery to the Femur This is derived from the second perforating artery. The primary centre for the shaft appears in the seventh week of intrauterine life. The posterioi surface is articular in its upper three-fourths and non-articular in its lower onefourth.

It is covered by an expansion frorr the tendon of the rectus femoris. Ossification of femur. The posterior articular surface is divided by. In addition. Presence of its centre in a newly born child found dead indicates that the child was viable.

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. This strip articulates with a reciprocal strip on the medial side of the intercondylar notch of the femur during full flexion. The apex is non-articula posteriorly. Tripping over minor obstructions or other accidents causing forced medial rotation of the thigh and leg during the fall results in: Features The patella has an apex.

The anterior surface is rough and non-articulai The upper three-fourths of the posterior surface ar smooth and articular. The articular area is divided by a vertical ridge into a larger lateral and smaller medial portion. The concavity of the neck-shaft angle is strengthened by a thickened buttress of compact bone.

The apex directed downwards. Another vertical ridge separates a medial strip from the medial portion. The patella is triangular in shape with its ape directed downwards. This mechanism helps in resisting stresses including that of body weight.

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. During different phases of movements of the knee. The lateral borderprovides insertion to vastus lateralis in its upper one-third or half. The superior surface of the condyle articulates with the lateral condyle of the femur.

Fusion is complete at puberty. The condition is bilateral and symmetrical Fig. 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 patella probably improves the leverage of the quadriceps femoris by increasing the angulation of the line of pull on the leg. The anterior and medial surfaces are marked by numerous vascular foramina.

It is homologous with the radius of the upper limb. The lower pair of articular facets articulates during extension. Attachments on the Patella The superior border or base provides insertion to the rectus femoris in front and to the vastus intermedius behind.

The upper end includes: As in the case of the medial condyle. Features The tibia has an upper end. The articular surface is nearly circular. Medial Condyle Medial condyle is larger than the lateral condyle. Upper End The upper end of the tibia is markedly expanded from side to side.

The lateral margin of the articular surface is raised to cover the medial intercondylar tubercle. One or two centres at the superolateral angle of the patella may form separate pieces of bone. The central part of the surface is slightly concave and comes into direct contact with the femoral condyle.

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 sinuously curved and terminates below at the anterior border of the medial malleolus. The articular surface has a raised medial margin which covers the 1. The projection is called the medial malleolus.

The medial side of the lower end projects downwards beyond the rest of the bone. The patella ossifies from several centres which appear during 3 to 6 years of age. Its superior surface articulates with the medial condyle of the femur. The non-articular area on the posterior surface provides attachment to the ligamentum patellae below. Such a patella is known as bipartite or tripartite patella.

Surfaces The lateral surface lies between the anterior and interosseous borders. Borders The anterior border is sharp and S-shaped being convex medially in the upper part and convex laterally in the lower part. It is subcutaneous and forms the shin. In its upper three-fourths. The medial surface is subcutaneous and is continuous with the medial surface of the medial malleolus. The medial surface lies between the anterior and medial borders.

Still further posteriorly this surface gives attachment to the tibial collateral ligament along the media border. It is a branch of the posterior tibial artery which enters the bone on its posterior surface. If the foot gets caught in a hole in the ground there may be forcible abduction and external rotation. Relations of the Tibia Apart from the relations mentioned above. A secondary centre for the upper end appears just before birth.

This may also be caused by tearing of the nutrient artery. The primary centre appears in the shaft during the seventh week of intrauterine life. The upper end of the tibia is one of the commonest sites for acute osteomyelitis. The groove for the tendon of the tibialis posterior continues downwards on the posterior surface of the medial malleolus. The deltoid ligament of the ankle joint is attached to the lower border of the medial malleolus Figs The tibia is commonly fractured at the junction of the upper two-thirds and the lower one-third of the shaft as the shaft is most slender here.

In such an injury. Separate secondary centres may appear for the tibial tuberosity and the medial malleolus Fig. The knee joint remains safe because the capsule is attached near the articular margins of the tibia. Sometimes a surgeon takes a piece of bone from the part of the body and uses it to repair a defect in some other bone called a bone graft. This is the commonest type of the fracture at the ankle. Forward dislocation of the tibia on the talus produces the characteristic prominence of the heel in this injury.

The upper epiphysis usually includes the tibial tuberosity. It is very thin as compared to the tibia. For this purpose pieces of bone are easily obtained from the subcutaneous medM aspect of the tibia. The tibia ossifies from one primary and two secondary centres. It is homologous with the ulna of the upper limb. A secondary centre for the lower end appears during the first year.

These stages are termed 1st. Such fractures may unite slowly. The medial surface of the shaft gives origin to: The posterior surface is the largest of the three surfaces.

Blood Supply The peroneal artery gives off the nutrient artery for the fibula. A secondary centre for the upper end appears during the fourth year.

The fibula violates the law of ossification because the secondary centre which appears first in the lower end does not fuse last. The fibula ossifies from one primary and two secondary centres. The groove on the posterior surface of the malleolus lodges the tendon of the peroneus brevis.

The reasons for this violation are: The primary centre for the shaft appears during the eighth week of intrauterine life. From medial to lateral side these are the medial cuneiform. In the first stage of Pott's fracture. Each tarsal bone is roughly cuboidal in shape. The tarsal bones are much larger and stronger than the carpal bones because they have to support and distribute the body weight.

Another bone. Though it does not bear any weight. The tarsus is made up of seven tarsal bones. In the proximal row. The fibula is an ideal spare bone for a bone graft. The upper and lower ends of the fibula are subcutaneous and palpable. The common peroneal nerve can be rolled against the neck of the fibula. This nerve is commonly injured here. In other words. In the distal row. The body bears a large triangular.

It has a head. R is directed forwards and slightly downwards d medially. The rounded head is directed forwards.
