Bones You Need to Know Femur Tibia Fibula Tarsals Talus Calcaneus Metatarsals Patella

Tarsals

These basic are bundled in two rows. In the proximal row, talus is present above and calcaneus below. In the distal row, four tarsal bones are lying next; (from medial to lateral side) medial cuneiform, intermediate cuneiform, lateral cuneiform and cuboid. Another os called the navicular bone is nowadays between the three cuneiform bones and the talus.

TALUS:

Information technology is ane of the largest tarsal bones. It consists of 3 parts i.e. head, neck and body. In that location are no muscular attachments on this bone. Information technology is covered by an articular cartilage. The superior surface of the trunk of talus makes a joint with the tibia bone of lower limb to course the ankle joint.

CALCANEUS:

It is the largest of all the tarsal bones. The prominence of the heel is made past this bone. It has 6 surfaces i.due east. inductive, posterior, superior, plantar, lateral and medial surface. The different surfaces of this bone give attachments to different muscles and ligaments of the pes. It makes joint with the talus and cuboid bones.

NAVICULAR:

It is a bone that resembles the shape of a boat. It is present on the medial side of the foot, behind the cuneiform bones and in front of the talus. It has 6 surfaces; anterior, lateral, medial, posterior, plantar and dorsal surface. It forms joint with the talus, cuneiform and cuboid bones. The muscle tibialis posterior is inserted into the tuberosity of the navicular bone. This tuberosity is present on the medial surface of the os.

CUNEIFORM BONES:

These are three in number i.e. medial, intermediate and lateral cuneiform basic. These bones are wedge shaped. These bones, at inductive end, form a joint with the metatarsal bones and at the posterior finish, with navicular bone. These bones provide attachment to the tibialis inductive and skid of tibialis posterior muscles.

CUBOID:

This is nowadays on the lateral side (dorsal row of tarsal basic) of the foot. It is present inductive to the calcaneus bone and posterior to the 4th and 5th metatarsal bones. Information technology has six surfaces i.due east. plantar, distal, proximal, dorsal, lateral and medial surfaces. The plantar surface of this os gives origin to the flexor hallucis brevis musculus.

SOME IMPORTANT CLINICAL ASPECTS:

The cervix (more often than not during dorsiflexion of the human foot) and trunk (mostly due to leap from a height) of talus tin can be fractured easily. In these fractures, there is fair take chances of avascular necrosis.

Calcaneus is besides fractured easily equally it is besides weight begetting os (with talus).

These basic are bundled in two rows. In the proximal row, talus is present above and calcaneus below. In the distal row, 4 tarsal bones are lying side by side; (from medial to lateral side) medial cuneiform, intermediate cuneiform, lateral cuneiform and cuboid. Another os chosen the navicular os is nowadays between the three cuneiform bones and the talus.

TALUS:

Information technology is i of the largest tarsal basic. Information technology consists of three parts i.e. head, neck and body. There are no muscular attachments on this bone. Information technology is covered by an articular cartilage. The superior surface of the body of talus makes a joint with the tibia bone of lower limb to form the ankle joint.

CALCANEUS:

It is the largest of all the tarsal basic. The prominence of the heel is made past this os. Information technology has six surfaces i.e. anterior, posterior, superior, plantar, lateral and medial surface. The different surfaces of this bone give attachments to different muscles and ligaments of the foot. It makes joint with the talus and cuboid bones.

NAVICULAR:

It is a bone that resembles the shape of a gunkhole. It is present on the medial side of the foot, behind the cuneiform bones and in front of the talus. It has six surfaces; anterior, lateral, medial, posterior, plantar and dorsal surface. Information technology forms joint with the talus, cuneiform and cuboid bones. The muscle tibialis posterior is inserted into the tuberosity of the navicular os. This tuberosity is present on the medial surface of the bone.

CUNEIFORM BONES:

These are three in number i.e. medial, intermediate and lateral cuneiform bones. These basic are wedge shaped. These bones, at anterior end, class a joint with the metatarsal basic and at the posterior end, with navicular bone. These basic provide zipper to the tibialis anterior and slip of tibialis posterior muscles.

CUBOID:

This is present on the lateral side (dorsal row of tarsal bones) of the foot. It is present anterior to the calcaneus bone and posterior to the 4th and 5th metatarsal bones. Information technology has six surfaces i.eastward. plantar, distal, proximal, dorsal, lateral and medial surfaces. The plantar surface of this bone gives origin to the flexor hallucis brevis muscle.

SOME IMPORTANT CLINICAL ASPECTS:

The neck (mostly during dorsiflexion of the foot) and body (mostly due to jump from a height) of talus can be fractured easily. In these fractures, at that place is off-white take chances of avascular necrosis.

Calcaneus is as well fractured easily as it is likewise weight bearing bone (with talus).
