Publisher: 1994Dissertation note: The fracture of patella usually falls in a special type of fracture, which is not treated by ordinary limb and bone fixation devices. Hence emphasis is given to counteract the distracting forces and to convert them into compressive forces to achieve the desired effects. Different types of internal fixation devices have been tried in the past for the repair of avulsion fractures like Tension Band wire, compression screws, compression plates, an steel sutures.
This study was conducted on 20 mongrel dogs divided into two groups of 10 animals each. These groups were designated as group A and group B. Two methods, Tension Band wire and square steel suture were used for the repair of transverse patellar fracture in dogs.
In group A, the right patella was surgically exposed, fractured and repaired by Tension Band wire with Thomas Splint on the same limb when the operated dog started bearing weight on its operated leg, the left patella was exposed and repaired using same technique but without Thomas Splint.
In group B the right patella was repaired by square steel suture with Thomas Splint. After six weeks, the left patella was operated and repaired using same technique but without Thomas Splint. The dog of each group was kept for a period of 16 weeks after surgery. The results were obtained on the basis of their clinical and radiographic picture.
The results of this study indicate that the use of steel suture is a better fixation device for the repair of transverse patellar fracture.

Publisher: 1996Dissertation note: A total of 120 broiler chicks were randomly selected and divided into six groups viz A, B, C, D, E and F, consisting of 20 birds each. At 4 week of age, A to E groups were experimentally infected with Salmonella pullorum inoculum. Group E (infected, non-medicated) and F (non-infected and non-medicated) were kept as control. The groups A, B, C and D were treated with Ampicillin 20%, Oxy-N-50, Chioricol10 and Trimodin forte, respectively, post infection. All the groups were kept under close observation to record signs and symptoms of disease, mortality, body weight gain and Feed Conversion Ratio. Gross lesions in visceral organs were also noted during this study. Some blood parameters (TEC, TLC and Hb content) were also estimated, pre and post infection. A mortality percentage in groups A, B, C and D were recorded as, 25%, 35%, 15% and 10%, respectively, while 70% mortality was recorded in control group F. According to this trial Trimodin forte (Trimethoprim Plus Sulphadiazine) . afforded maximum protection against infection and proved best in relation to weight gain and F.C.R. Chloricol-10 (Chioramphenicol) stood second in the list, while Ampicillin-20% (Ampicillin Trihydrate) was the third drug in furnishing protection against the infection. Whereas, Oxy-N-50 (Oxytetracycline plus neomycin sulphate) was the least effective drug in respect of protection against pullorum disease. The signs of ill health appeared 3 to 4 days post infection were listlessness, ruffled feathers, droopy wings, loss of appetite, poor growth, depression, increased thirst and severe diarrhoea of chalky white colour. The postmortem findings were enlarged and congested liver streaked with haemorrhages, 2-3 times enlarged spleen (spleenomegaly), enlarged heart and pericarditis, congested and distended kidneys, area of gray hepatization in lungs, thickened and inflammed intestinal walls and presence of necrotic foci in cardiac muscles, liver, spleen, lungs, caeca, large intestine and muscles of gizzard. The Total Erythrocytic count and Haemoglobin contents were decreased and Total Leukocytic Count, were increased 3 days post infection. The findings of the present study will further elucidate the disease and help in diagnosis and treatment of this malady on large scale.

; Nature of contents: ; Literary form: Publisher: 1998Dissertation note: Mid shaft tibial fractures can be repaired by external and internal methods of fixation. The internal methods include bone plates, bone screws, intramedullary pins, circiage wires etc. whereas external fixation devices include K.E. apparatus, Thomas splint, P.O.P. (Gypsona cast splint) other casts and fixation devices. In the cases of mid shaft tibial fracture in the dog, it is not necessary all the times to repair it by internal methods of fixation. External methods of fixation are comparatively cheaper and easy to apply and handle and prevent the animal from the post-operative complications of internal methods of fixation.
The present study was launched for the comparison of the external fixation devices used for the repair of mid-shaft tibia fracture in the dog i.e.
a) Gypsona cast splint.
b) K.E. apparatus.
c) Thomas splint.
The study was carried out on 12 mongrel dogs of either sex divided into four groups i.e. A, B, C and D and each groups comprising three animals designated as I, II and III. In group A, after the induction of mid shaft tibial fracture Gypsona cast splint was applied on right limb. In group B, K-E. apparatus and in group C Thomas splint was applied. The group D was held sham operated (control) after the induction of mid-shaft tibial fracture. The aforesaid devices were first applied on right tibia and then on left tibia of the same dog at an interval of 10 weeks. The dogs were kept in kennels for 20 weeks. At the end of experimental period, the dogs were euthanized and gross examination was conducted.
The results were collected on the basis of clinical examination (lameness) radiographs and post-euthanasia findings. The results clearly revealed that K-E. apparatus was the best choice in cases of mid shaft tibial fracture in the dog, in terms of best immobilization and good calus formation. Although K.E. device is costly one, but it won't exceeds the cost of the animal in many cases. The results were excellent and procedure can easily be applied easily by an average Orthopaedic surgeon. Thomas splint comes next to K-E. apparatus. If properly applied gives good results. Gypsona cast splint was graded at the end, due to its less efficacy and accuracy. It usually resulted in bone bending after application. It could have been a better procedure if applied with some metallic cast or splint.

Publisher: 1978Dissertation note: The study of "Treatnt of TibiaS fractures in the cog" through pinning end plating was undertaken primarily for introducing this branch of orthopaedic surgery here to keep pace with other countries of the erld, besides ascertaining the conp are- tive efficiency of both the aforesaid techniques. A total number of 32 dogs of local breed were selected for this purpose and were divided into eight groups of four animals each, The ani:aals in one group n of the sane sex and aqroximately of uniform age, size and weight, tine group of animals was used at a time, The left tibiae of the animals were broken approximately in the zui&ie with the help of chisel and haaaer under general anaesthesia of Intraval Sodiwa, Half of the fractures were ictnobilized using stainless steel intrameduUary pins and the recaining half by stainless steel bone plates, The aninols were kept under the same environmental conditions and fed on sane ration during the post-operative period, The results indicated that both the methods were just equaUy good as far as iaobilization art callus formation was concerned, However, pinning is prefexrd in view of its being simple ext less laborious both at the time of its introduction and removal after recovery. runhcr,,:e, from experiencing very negligible post-operative cocç; ications, pinning was quite economical as compared to plating,
