Enzymes are biocatalysts composed of amino acids. Enzyme reactions are highly specific. It binds to the substrate to form a reversible intermediate product called enzyme substrate complex. As the concentration of the substrate increases the rate of formation of the intermediate complex also increases. This increase in velocity of the reaction is in a hyperbolic manner till it achieves the maximum velocity called Vmax .At this point all the enzymes will be in the form of ES complex. Substrate concentration will be in at its optimum level i.e. further increase in substrate concentration will not affect the rate of the reaction. The substrate concentration at which the rate of the reaction is half the maximum velocity Vmax is called the Michaelis-Menten constant, Km. This is constant for the given enzyme acting on the same substrate.

Centre of gravity

It is most commonly located is the middle of the rib cage, just caudal to the line separating the cranial and middle third of the body because the CG & located more cranially. The forelimbs bear 60-65% of body weight. This causes an increased stress of forelimb and increase incidence of lameness. The horse that is taller over the group than the wither has an additional disadvantage, because PTS CG is shifted further forwards.

1. Long backed horses may develop a swing in the gait that alters the movement of their limbs. Such horses are prone to speedy cutting. Cross firing & back problem due to muscle ligament strain.

2. Short backed horses may develop a swing in the gait that alters the movement of these limbs. Such horses are prone to speedy cutting, cross firing & back problem due to muscle and ligament strain.

Gait of ANormal Animal

This is a four - beat gait. Walking can be of various forms, but regardless of the form, it must be an even four beat gait.

When a regular sequence is lost, identified by four hoof beats at precise interyals, the cattle is no longer walking.

The walking sequence is lateral because both feet of one side hit the ground before the two feet of opposite side strike.

Propulsion primarily results from the hindlimbs, and the forelimbs simply follow.

The length of stride in the walk will usually vary between 5 1/2 and 6 ft. This distance is measured between successive imprints of the same foot.

The step will vary between 33 and 39 inches and is the measurement made between the imprints made by a pair of forefeet or the imprints made by a pair of hind feet.

The sequence of the hoof beats can be described according to this pattern: (1) near - hind, (2) near - fore, (3) off - hind, (4) off - fore.

This gait is sometimes described as beginning with a forelirnb as ; (1) off — fore, (2) near - hind, (3) near - fore, and (4) off - hind.

This description is not proper according to the way the cattle starts, but it is proper after it is in motion.

The condition in the young subject is as follows:

The two parietals are united with each other and also with the interparietal and supraoccipital. The resulting mass is somewhat horse shoe shaped. Its occipital part (planum occipitale) forms the greater part of the posterior wall of the cranium and bears about its centre the tubersity for the attachment of the ligamentum nuche. From either side of this a line curves outward and divide the surface into an upper smooth area and a lower area which is rough for muscular technique. The upper borderjoins the frontal bone and concurs In the formation of the frontal eminence. The temperal part (Plana temporalla) are much smaller and are concave externally; they join the frontal above and the squamous temporal below. A median occipital crest extends ventrally from the external occipital protuberance.

Meatus acusticus externus

This vertebra is decidedly atypical in form and structure. The body and spineous process are absent. It has the form of a strong ring, from which two curved plates, the wings, project laterally. The ring incloses a very large vertebral foramen and consistis of two lateral masses connected by dorsal and ventral arches.

The lateral masses (Massae laterales) present two deep oval anterior articular cavities (Foveae articulares craniales) which receive the occipital condyles; they are separated by a wide notch above and a narrow one below. The lateral margin is also notched, and a triangular non-articular depression cuts into the medial part of each cavity. The posterior articular surfaces (Facies articulares caudales) are somewhat saddle-shaped; they are confluent on the ventral arch, but are widely separated dorsally, and do not conform in shape to the corresponding surfaces of the axis.

The dorsal arch (Arcus dorsali,) presents a median dorsal tubercle (Tuberculum dorsale) and is concave ventrally. It is perforated on either side near its anterior margin by the inter vertebral foramen (Foramen invertebrale). The anterior border is deeply notched, and the posterior border is thin and concave.

The ventral arch (Arcus ventralis) is thicker, narrower, and less curved than the dorsal. In its lower surface is the ventral tubercle (Tuberculum ventrale), into which the terminal tendon of the longus colli muscle is inserted. The upper face has posteriorly a transversely- concave articular surface, the fovea dentis, on which the dens or odontoid process of the axis rests.

In front of this is a transverse rough excavation and a ridge for the attachment of the ligamentirm dentis.

The cervical vertebrae are 7 in number.

The first and second cervical vertebrae are highly modified in conformity with the special function of support and movements of the head.

The third, fourth and fifth have the following characters:

The body is long. Ventral surface present a median ventral spine.

The dorsal surface has a flat central area which is narrow in the middle of the vertebrae, and wide at either end. On either side of this area there is a groove which lodges the longitudinal spinal vein.

The anterior extremity or head has an oval articular surface which faces forward and downward; it is strongly convex and wider above than below.

The posterior extremity is larger and has a nearly circular cotyloid cavity.

The arch is large and strong. It is perforated on either side by foramen which communicates with the foramen transverse hum. The vertebral notches are large.

The articular process are large. Their articular surface are extensive, oval in outline, and slightly concave.

LUMBAR VERTEBRAE (Fig. 1)

Lumbar vertebrae, six in number, are much longer than in the horse.

The body is much constricted in the middle, expanded at either end, and bears a rudimentary ventral crest.

The articular processes are large, and their facets are more strongly cun/ ed than in the horse.

The transeverse processes ail’curve foPA/ard, borders a.^e thin and irregular and often bear projections of variable size and form..

The spinous processes are relatively low wide, the last being the smallest; their summits are moderately thickened.

The scapula is more regularly triangular than in horse, relatively, wider at the vertebral end and narrower at the distal end. The scapular index is about T.0.6. The spine is more prominent and is placed further forward, so that the supras- pinous fossa is narrow and does not extend to the lower part of the bone. The spine is sinuous, bent backward in its middle, forward below. Its free border is somewhat thickened in its middle, but bears no distinct tuber. Instead of little more prominent, and is prolonged by a pointed production, the acromion, from which part of the deltoid muscle arises. The sub scapular fossa is shallow. The areas for the attachment of the stratus muscle are not very distinct. The nutri- ent foramen is usually in the lower third of the posterior border. The glenoid cavity is almost circular and without any distinct notch. The tuberosity is small and close to the glenoid cavity. The coracoid process is short and rounded. The cartilage resembles that of the horse. The tuberosity unites with the rest.

Four digits are presents in the ox of these two the third and forth -are fully developed and have three phalanges and three sesamoid each.The second and fifth are vestiges.

FRIST PHALANX- (Fig.No.1)

The interdigital surface is flattened and its volor parts bears a prominence for the attachment of the interdigital ligaments.

The proximal extremity is relatively large and somewhat compressed from side to side.

The articular surface is concave from before backword and is divided by sagittal groove in two areas, of which the aboxial one is the larger and higher.

Behind tese are two facets for articulation with the sesamoid bones.

The distal extremity smaller than the proximal.

The ilia are almost parallel to each other and form a much smaller angle with the horizontal plane than in the horses.they are relatively small. The glutei line is prominent and nearly parallel to the lateral border,it joins the ischiatic spine.A rounded ridge separates the two parts of pelvic surface.The surface for articulation with sacrum is triangular. The tuber coxae is relatively prominent and not so oblique as in horses, wide in middle,smaller at either end.Shaft is short and compressed from side to side.

Ischium is large.Its long axis is directed obliquely upward and downward forming an angle of 5o to 60 degree with horizontal plane.The transverse axis is obliquely downward and inward at similar angle so concave from side to side.Ventral surface has rough ridge for muscular attatchment. The ischiatic spine is high and thin and bears a series of vertical rough line. lschiuatic arch is narrow and deep.The tuber ischii is large and three sided bearing dorsal ,ventral, lateral tuberosities.The symphysis bears a ventral ridge which fades out at ischial arch.The acetabular branch of pubis is narrow and is directed laterally,and a little forward.The anterior border is marked by a transverse groove which ends below rough iliopectineal eminence. The symphyseal branch is wide and thin. The acetabulum is smaller than in horses. Rim is rounded and usually marked by two notches. One is directed to deep acetabular fossa and and converted to foramen. The other is anteromedial and small also replaced by foramen or absent.

ILIUM

The ilium are almost parallel to each other and form a much smaller angle with the horizontal plane than in the horse. They are relatively small. The gluteal line is prominent and is nearly parallel to the lateral border; it join the ischiatic spine. A rounded ridge separates the two parts of the pelvic surface. The surface for articulation with the sacrum is triangular. The tuber sacrale is truncated, does not extend so high as the vertebral spines, and is separated from the opposite angle by a wider interval than in the horse. The tuber coxae is relatively large and prominent; it is not so oblique as in the horse, and is wide in the middle, smaller at either end. The shaft is short and compressed from side to side.

FEMUR

The femur has a relatively small shaft, which is cylindrical in its middle. The trochanter minor has the form of a rough tuberosity.

The trochanteric ridge connects it with the trochanter major. The third trochanter is absent. The supracondyloid fossa is shallow. The proximal extremity is very wide.

The fovea capitis is a small depression on the middle of the heacKfor the attachment of the round ligament.

The trochanter major is very massive and is undivided; its lateral surface is very rough. The trochanteric fossa is deep. The ridges of the trochlea are less oblique.

First Aid in Orthopaedic Patient

Immediately transfer the animal to a safety place.

The place should be well settled, well ventilated, neat and clean.

If the fracture site is limb and it is a simple fracture, immediately immobilize the animal with soft cotton padding and plastic scale placed at four sites.

If the fracture site is limb and it is a compound fracture, cover the fractured site v/ith th’ck padded clean cotton cloth and few bamboo splint placed on four sides to keep limb straight.

Control the bleeding, if bleeding occurs at time of covering of fractured site with thick padded clean cotton cloth.

If the fracture site is vertebral column, it is better not to lift the patient vigorously.

A patient with vertebral column fracture shouldn’t be allowed for standing.
