Aim

To know the portion of limb to be covered by P.O.P cast bandage for immobilization of fore limb (Fig 1a) & hind limb ( Fig 2a) bone fracture.

As per general rule, joint below and joint above should be covered.

Aim: Amputation of limb by bone section technique.

Indication: Irreparable injury; Gangrene; Malignant disease.

Site:

Fore-limb: Common site is junction of the lower and middle third of the radius(fore-arm).

Hind-limb: common site is the middle third of the leg region(tibia).

Anaesthesia and control: Fore-limb: general anaesthesia; Hind-limb: epidural anaesthesia. Operated in lateral recumbent position.

Libido • It is the willingness & eagerness of male animal to mount and perform complete service. It is sexual desire or drive which is an innate character of male animals. • Libido and mating ability have no direct relation with fertility. Libido is not related directly to sperm production and semen quality. • The libido of an animal depends on androgenic steroid hormone. Vasectomy or cryptorchidism does not affect libido in male animals. • Animals have no or reduced libido that are castrated before puberty. If the animals, that know the copulation, are castrated after puberty, they display the copulation behaviour for longer period. • Reaction time – It is the time between the contact of a male animal with female animal to 1st false mount with erected penis. Reaction time is the good predictor of libido.

Lipoma is a benign tumor of adipocytes and it is more common in dogs and mostly observed in the trunk, thigh and proximal limbs with rare presence of ulceration.

Liposarcoma is a rare malignant tumor of adipocytes in dogs. Grossly, the neoplastic cells are arranged in less circumscribed to large firm to hard (Figure 67) nodules on the dermis and the nodules noticed on the subcutis are grey white in color.

Local Anesthetic Techniques of Head Region
The following nerves can be blocked in the head region for performing surgery.
    1.    Cornual nerve block 
    2.    Peterson’s orbital nerve block 
    3.    Auriculopalpebral nerve block 
    4.    Supra orbital nerve block 
    5.    Infra orbital nerve block 
    6.    Retro bulbar nerve block 
    7.    Mental nerve block 
    8.    Maxillary nerve block 
    9.    Mandibulo alveolar nerve block 

These are the drugs that reversibly block the propagation of action potentials along nerve axons. General anesthesia may be advantageous where complete immobilization and relaxation of the patients required. However, local anesthetic techniques are advantageous for providing surgical anesthesia in animals that are considered at risk for inhalant or intravenous anesthesia. These drugs are injected directly at the target site.

DEFINITION

Lower level fracture in animals include any fracture of the region from knee joint to foot in forelimb and from hock joint to foot in hind iimbs.

CFERA’nVE PROCEOURE-H ere the principle of treatmient is application of cast and conjoint metal ‘U’ plate over the fractured site. Permanent immobilization of the limb should be done only after 7 days to subside.

Length to be covered-Forelimb-above knee joint and below foot. Hind limb-above hock joint and below foot, (as shown in fig.1)

Padding-6-12 layer thick padded cloth should be vmapped applying gum.s throughout the doth area, over the fracture, it should not be too tight but it should be strong. Sloughing off the hoof may result due to hypostatic congestion; hence the hooves should not be left open. (Cotton pad as shown in fig.2)

Fracture of meta-carpals and meta-tarsals comes under lower level fracture. Padded cloth and netted bamboo splint along with conjoint U plate has been considered as standard method of repair.

The fractufe is a lower level fracture involving the meta-carpal and meta- tarsal bones. (Fig.1 & Fig.2)

The fracture site is immobilized extending joint below and joint above level initially with cloth or cotton padding.(Fig.3)

Netted bamboo splint Is applied over it for support involving joint above and joint below which should not be too tight or too loose.(Flg.4)

Splints are retained in position by thread with knots. The ends of bamboo splint kept padded to avoid skin damage.(Fig.4)

More strength is given to immobilisation by application of conjoint U- plate.Conjoint U-plate is a U shaped metallic plate used for lower level fracture immobilisation. (Fig.5 & Fig.6)

At the end the entire bandage is covered with cloth or a bandage roll.The hoof should also be bandaged to avoid damage due to improper blood circulation.(Flg.6)

Luxation/Dislocation : It refers to the displacement of opposing articular surfaces of bone. The direction of displacement is described with reference to the distal bone in relation to the proximal bone.

Subluxation : It refers to partial or incomplete dislocation.

Classification
    1.    Acute : Recent occurrence of luxation.
    2.    Chronic : Luxation existing for a long time.
    3.    Recurrent : Reluxation after correction.
    4.    Simple : No open wound is communicating with the joint.
    5.    Compound : Open wound is communicating with the joint.
    6.    Pathological : Dislocation due to any pathological lesion.

Systematic recording is vital for smooth running of any artificial insemination enterprise. All the information in the center should be so arranged so that it can be readily be traced out and used for analysis of performance of the center. The records should be critically analyzed for selecting better animals / personnel and for improving reproductive management. The objective of record keeping is as follows.

A very common condition caused by Malassezia pachydermatis in dogs. It is also caused by predisposing allergic skin disease. It occurs in ventral neck, ventral abdomen, axilla, face, pinnae, feet and forelegs. Tape impression smear will reveal numerous yeasts.

Key Points

• In diary animals, the health of the mammary gland (udder) is paramount.

• Any udder or teat disease state has a direct impact on milk output.

• Common udder/teet affections include: abscess, mammary gland hematomas, udder cleft dermatitis, udder edema, intramammary hemorrhage, teat damage, ulcerative mammillitis, udder dermatitis, and more.

Introduction

Mammary gland (udder) health is a crucial factor in animals used for production. The state of the udder determines the dairy industry's economics. The output of dairy animals is directly impacted by any udder ailment. Due to selection, breeding, genetic engineering, and animal management, animals under production pressure are more susceptible to a variety of diseases. More safety measures should be implemented in order to shield the udder from illness-causing factors. The many udder and teat affections and their therapeutic management are briefly discussed in this chapter.

One of the most common fractures seen in the dog is comminutuion of femoral shaft, often related to sever impact from an automobile accident or jump from a height. Comminuted fractures are characterized by one or more butterfly fragments and assorted small bone chips that are especially difficult to align accurately and stabilize completely. These complicated fractures require sophisticated repair technique that are capable to resisting compression, bending and rotational forces. Rebuilding of comminuted fractures so that all fragments are accurately aligned and gaps are eliminated is often impossible. Non-union and osteomylitis have their highest incidence in these fractures. Over the years, several techniques are tried to treat comminuted femoral fractures with different success rate and there is a lack of uniform fracture presentation. Hence, it will be difficult to compare different techniques in a particular type of fracture. The present chapter is, therefore, undertaken to evaluate radiographically and histopathologically the efficacy of three different internal fixation techniques in the management of comminuted diaphyseal femoral fracture in dogs.

Clinically healthy, adult mongrel dogs (15) of either sex are randomly divided into groups A, B and C of 5 animals each. In all the animals unilateral comminuted diaphyseal femoral fractures is created under general (thiopental - 5%) anaesthesia and is immobilized with intramedullary (IM) pinning with cerclage wiring (Gr. A), neutralization bone plating (Gr. B) and neutralization bone plating with cerclage wiring (Gr. C) respectively. All the animals are administered broad spectrum antibiotic (streptopenicillin @ I g intramuscularly (dog/day) and analgesic (diclophenac sodium @ l mg/ kg b. wt. daily) and surgical wounds are dressed daily with povidone iodine and antibiotic cream for 5 days postoperatively.

Lateral and oblique views of radiography are taken at the operated site just after the operation and subsequently on days 15, 30, 45 and 60 postoperatively. The radiographs are observed for status of fracture reduction and fixation, progress of healing at the fracture site and complications like fixation failure, osteomylitis etc., if any, at different intervals. Bone sections are collected from the fracture site including adjacent normal bone after sacrificing the animals on day 60. The sections are decalcified using Goodling and Stewart’s solution (80% distilled water, 15% formic acid and 5% formalin) and then processed routinely for H & E staining for histopathological studies
