Superior surface

The superior surface of the body presents, behind, a smooth trochlear surface, the trochlea, for articulation with the tibia.


The trochlea is broader in front than behind, convex from before backward, slightly concave from side to side: in front it is continuous with the upper surface of the neck of the bone.


Inferior surface

The inferior surface presents two articular areas, the posterior and middle calcaneal surfaces, separated from one another by a deep groove, the sulcus tali.


The groove runs obliquely forward and lateralward, becoming gradually broader and deeper in front: in the articulated foot it lies above a similar groove upon the upper surface of the calcaneus, and forms, with it, a canal (sinus tarsi) filled up in the fresh state by the interosseous talocalcaneal ligament.


The posterior calcaneal articular surface is large and of an oval or oblong form.


It articulates with the corresponding facet on the upper surface of the calcaneus, and is deeply concave in the direction of its long axis which runs forward and lateralward at an angle of about 45° with the median plane of the body.


The middle calcaneal articular surface is small, oval in form and slightly convex; it articulates with the upper surface of the sustentaculum tali of the calcaneus.


Medial surface

The medial surface presents at its upper part a pear-shaped articular facet for the medial malleolus, continuous above with the trochlea; below the articular surface is a rough depression for the attachment of the deep portion of the deltoid ligament of the ankle-joint.


Lateral surface

The lateral surface carries a large triangular facet, concave from above downward, for articulation with the lateral malleolus; its anterior half is continuous above with the trochlea; and in front of it is a rough depression for the attachment of the anterior talofibular ligament.


Between the posterior half of the lateral border of the trochlea and the posterior part of the base of the fibular articular surface is a triangular facet which comes into contact with the transverse inferior tibiofibular ligament during flexion of the ankle-joint; below the base of this facet is a groove which affords attachment to the posterior talofibular ligament.


Posterior surface

The posterior surface is narrow, and traversed by a groove running obliquely downward and medialward, and transmitting the tendon of the Flexor hallucis longus.


Lateral to the groove is a prominent tubercle, the posterior process, to which the posterior talofibular ligament is attached; this process is sometimes separated from the rest of the talus, and is then known as the os trigonum.


Medial to the groove is a second smaller tubercle.

Bones of the Hip In anatomy, the hip is the bony projection of the femur, known as the greater trochanter, and the overlying muscle and fat. ... The medial surface of the Upper extremity of femur, of much less extent than the lateral, presents at its base a deep depression, the trochanteric fossa (digital fossa), for the insertion of the tendon of the Obturator externus, and above and in front of this an impression for the insertion... The Lesser Trochanter (small trochanter) of the femur is a conical eminence, which varies in size in different subjects; it projects from the lower and back part of the base of the neck. ... Running obliquely downward and medialward from the tubercle of the femur is the intertrochanteric line (spiral line of the femur); it winds around the medial side of the body of the bone, below the lesser trochanter, and ends about 5 cm. ... Running obliquely downward and medialward from the summit of the greater trochanter on the posterior surface of the neck is a prominent ridge, the intertrochanteric crest. ... The body of the femur (or shaft), almost cylindrical in form, is a little broader above than in the center, broadest and somewhat flattened from before backward below. ... The linea aspera is a ridge of roughened surface on the posterior aspect of the femur, to which are attached muscles and intermusclular septa. ... The linea aspera is a ridge of roughened surface on the posterior aspect of the femur, to which are attached muscles and intermusclular septa. ... The upper part of the gluteal tuberosity is often elongated into a roughened crest, on which a more or less well-marked, rounded tubercle, the third trochanter, is occasionally developed. ... On the posterior surface of the femur, the intermediate ridge or pectineal line is continued to the base of the lesser trochanter and gives attachment to the pectineus muscle. ... The lower extremity of the femur (or distal extremity), larger than the upper extremity of femur, is somewhat cuboid in form, but its transverse diameter is greater than its antero-posterior; it consists of two oblong eminences known as the condyles. ... The medial lip of the linea aspera ends below at the summit of the medial condyle, in a small tubercle, the adductor tubercle, which affords insertion to the tendon of the Adductor magnus. ... The lateral epicondyle of the femur, smaller and less prominent than the medial epicondyle, gives attachment to the fibular collateral ligament of the knee-joint. ... The medial epicondyle of the femur is a large convex eminence to which the tibial collateral ligament of the knee-joint is attached. ... The lateral condyle is one of the two projections on the lower extremity of femur. ... The medial condyle is one of the two projections on the lower extremity of femur. ... The articular surface of the lower end of the femur occupies the anterior, inferior, and posterior surfaces of the condyles. ... This article is about the vertebrate bone. ... The upper extremity of the tibia (or proximal extremity) is large, and expanded into two eminences, the medial condyle and lateral condyle. ... Posteriorly, the medial condyle and lateral condyle are separated from each other by a shallow depression, the posterior intercondyloid fossa (or intercondylar area), which gives attachment to part of the posterior cruciate ligament of the knee-joint. ...

FIG. 268– Bones of the right foot. ... The calcaneus is the large bone making up the heel of the human foot. ... At the upper and forepart of the medial surface of the calcaneus is a horizontal eminence, the sustentaculum tali, which gives attachment to a slip of the tendon of the Tibialis posterior. ... The two oblique grooves of the lateral surface of the calcaneus are separated by an elevated ridge, or tubercle, the trochlear process (peroneal tubercle, or fibular trochlea of calcaneus), which varies much in size in different bones. ...
