Diagnostics and treatment of cranial cruciate ligament rupture
Prednji križni ligament jedan je od glavnih stabilizatora koljenog zgloba kod pasa i ljudi. PuknuÄe prednjega križnog ligamenta najÄeÅ”Äi je razlog Å”epanja i bolnosti stražnje noge kod pasa te može biti razliÄite etiologije. U veÄini se sluÄajeva radi o kroniÄnom procesu, a ne o akutnoj traumatskoj ozlijedi. PuknuÄe može biti djelomiÄno ili potpuno. Prilikom ortopedskog pregleda bitno je odrediti o kakvom se puknuÄu radi te je li doÅ”lo do ozljede meniska. Ortopedski se pregled preporuÄuje izvoditi u sedaciji zbog boljih rezultata i smanjene bolnosti pri pregledu. LijeÄenje može biti konzervativno i kirurÅ”ko, a odabir ovisi o starosti i veliÄini psa, starosti procesa te moguÄnostima i željama vlasnika.The cranial cruciate ligament is one of the most important stabilizers of the stifle (knee) joint in dogs and humans. Rupture of cranial cruciate ligament is one of the most common reasons for hind limb lameness and pain and it has various different etiologies, most of the cases are chronic processes rather than acute trauma. Rupture can be partial or full rupture. When doing an orthopedic exam it is important to discern what kind of rupture it is, and whether the meniscus is damaged or not. It is advised to sedate the animal prior to the orthopedic exam. When the animal is calm, the muscles are relaxed and the examination is less painful which ensures more accurate results. Treatment can be non ā surgical and surgical, depending on the dog size, age, duration of the lesion, and on the wishes and possibilities of the owner
Ventralna abdominalna hernija u nimfe (Nymphicus hollandicus) - prikaz sluÄaja
Not many abdominal hernias in small birds have been clearly described. As in other animals, ventral abdominal hernias have been characterized as a separation of the abdominal musculature on the ventral midline. Hernias are often related to breeding, egg binding or influenced by hormones. This article describes one case of abdominal hernia in a five year old female cockatiel. A painless, 3cm in diameter and non-reducible mass was located in the ventral abdominal region. The mass was less than 1 cm from the cloaca. The bird had had problems with defecation for several months. After clinical examination and contrast radiogram, an abdominal hernia was diagnosed. Surgical repair was performed under general anesthesia and herniorrhaphy was indicated. After skin incision, a large mass of yellowish fat tissue was discovered and the intestines within with adhesions. The hernial sack contents were resected using blunt cotton swabs soaked in saline. For repair of the abdominal hernial ring and the abdominal wall, a simple continuous suture pattern with polyglyconate 4-0 was used. The skin was also sutured with a simple continuous pattern. Normal defecation returned within hours post op. The follow up examination after one month revealed no complications and no recurrence of the hernia.U danas dostupnoj literature nema puno prikaza sluÄajeva kila u malih ptica. Kao i u drugih životinja ventralne abdominalne kile opisane su kao razdvajanje miÅ”iÄja trbuÅ”nog zida u srediÅ”njoj ventralnoj liniji. Kile u ptica su Äesto povezane sa reprodukcijom, zaostalim jajetom ili hormonima. Ovaj Älanak prikazuje sluÄaj ventralne trbuÅ”ne kile u pet godina stare nimfe. Bezbolna, 3 cm u promjeru, nereponibilna tvorba primjeÄena je na ventralnom dijelu trbuha. Tvorba je bila smjeÅ”tena manje od 1 cm od kloake. Nimfa je imala problema sa zaÄepom nekoliko mjeseci. Nakon kliniÄkog pregleda i kontrastnog rendgenograma, dijagnosticirana je ventralna trbuÅ”na kila. KirurÅ”ko lijeÄenje provedeno je u opÄoj anesteziji te je uÄinjena herniorafija. Nakon kožnog reza primjeÄena je velika žuta masa masnog tkiva te zavoji tankog crijeva sa priraslicama. Sadržaj hernijalne vreÄe je reseciran i prepariran tupo pomoÄu Å”tapiÄa s vatom natopljenih u fizioloÅ”ku otopinu. Za Å”ivanje i rekonstrukciju hernijalne vreÄe i trbuÅ”ne stijenke koriÅ”ten je produžni Å”av poliglikonatom 4-0. Koža je saÅ”ivena takoÄer produžnim Å”avom. Nekoliko sati poslije operacije ptica je dobila stolicu. Mjesec dana poslije operacije ptica nije pokazivala nikakve simptome povrata kile i obstipacije
Management of Long Bone Fractures in Young Animals
U mladih životinja koje joÅ” nisu zavrÅ”ile s rastom ploÄe rasta graÄene su od hrskavice koja Äe se s procesom sazrijevanja mineralizirati. U najÄeÅ”Äe lomove u mladih životinja ubrajamo greenstick-lomove, avulzijske lomove te fizne lomove. Lomove koji zahvaÄaju fize prema Salter-Harrisovoj klasifikaciji dijelimo na Å”est tipova. SpecifiÄnost je mladih kostiju da stvaraju snažniji kalus nego odrasle, a sam je proces cijeljenja brži. Konzervativno lijeÄenje lomova jest stabilizacija upotrebom imobilizacijskih povoja te udlaga bez otvorenoga kirurÅ”kog pristupa. Operacijsko lijeÄenje loma jest primjena kirurÅ”kog pristupa kako bi se mogla postiÄi anatomska repozicija, odnosno rekonstrukcija fragmenata pomoÄu implantata koji bi ih držali na mjestu. NajÄeÅ”Äe se upotrebljavaju vanjski fiksatori, ploÄe i vijci te intramedularni Äavli.In young animals that have not yet finished growing, the growth plates are made up of cartilage that will mineralize with skeletal maturation. The most common fractures in young animals include: greenstick fractures, avulsions and physeal fractures. Fractures involving the physis are classified into 6 types according to the Salter-Harris classification. The specificity of young bones is that they create a stronger callus than adult bones, and that the healing process itself is faster. Conservative treatment of fractures involves stabilization using immobilization bandages and splints, without creating a surgical wound and opening a surgical field. Surgical treatment of a fracture is the use of a surgical approach in order to achieve anatomical reposition and reconstruction of fragments using implants to hold them in place. The most commonly used implants are external fixators, plates and screws, and intramedullary pins
Surgical Treatment of Scapular Fractures in Dogs and Cats
Lomovi lopatice rijetko se pojavljuju u veterinarskoj medicini. Uzroci su tupe traume, no u mladih životinja mogu se pojaviti i avulzijski lomovi. Nestabilni lomovi i artikularni lomovi lopatice zahtijevaju kirurÅ”ko lijeÄenje. VeÄe koÅ”tane fragmente na lopatici stabiliziramo upotrebom ortopedskih ploÄica, igala i vijaka ili serklažne žice, te kombinacijom ovih metoda. Lomovi manjih koÅ”tanih fragmenata stabiliziraju se priteznim ortopedskim vijcima, serklažnom žicom i ortopedskim iglama. Artikularni lomovi povezani su s dugoroÄnom rezidualnom hromoÅ”Äu. MoguÄe metode oÄuvanja dijela uda ukljuÄuju djelomiÄnu ili potpunu skapulektomiju ili artrodezu ramenog zgloba. Izostankom dubokog bola prognoza je nepovoljna i u tom se sluÄaju preporuÄuje kompletna amputacija.Scapular fractures are rarely seen in veterinary medicine. They are caused by blunt force trauma, but still, avulsion fractures can also occur in young animals. Unstable fractures, as well as articular fractures, require surgical treatment. Bone plates, Kirschner wire, bone screws, orthopedic wire and their combination stabilize larger fragments. Smaller bone fragments are stabilized with lag screws, orthopedic wire, and Kirschner wire. Articular fractures are linked with long-term residual lameness. Amputation with scapulectomy or shoulder arthrodesis is a viable salvage procedure. Loss of deep pain sensation is linked with poor long-term prognosis and warrants amputation
SpororastuÄi osteosarkom lopatice u psa mops pasmine - prikaz sluÄaja
A scapular bone tumor in a 7-year-old male Pug is described. The Pug accidentally ran into a door six years before and started to limp on his front right leg. A small mass was noticed by the Pugās owners on his right shoulder which was ignored by the veterinarian. The mass increased in size until it became 9 cm in diameter and the dog was not using his leg occasionally. Finally the dog was referred to the Surgery, Ophthalmology and Orthopedics Clinic for further diagnostics. Following complete clinical and orthopedic examinations, an X-ray of the right scapula was performed and a neoplasia of the scapulae was suspected. A biopsy and histopathological examination was recommended in order to rule out osteosarcoma. The histopathological examination established the diagnosis of a highly productive, osteoblastic osteosarcoma of the right scapula with pulmonary metastasis. Prognosis was unfavorable due to metastases to the lungs evidenced by the X-ray. We report a case concerning an untreated scapular neoplasia with X-ray detectable lung metastases upon presentation at the Clinic. Proper diagnosis should be based on clinical examination, radiograph evaluation of the process and histopathological findings after bone biopsy. Blunt trauma can be a trigger for development of slow growing periosteal osteosarcoma, as described here. Treatment often include subtotal scapulectomy or forequarter amputation with adjuvant chemotherapy. Despite aggressive treatment, scapular osteosarcoma has a poor prognosis with low median survival time and disease free interval in dogs. Unfortunately the Pugās owners refused the recommended treatment and the dog was euthanized 2 months later.Opisan je tumor lopatice u sedmogodiÅ”njega muÅ”kog mopsa. Kao Å”tene, sluÄajno je naletio na vrata i poÄeo Å”epati na prednju desnu nogu. Vlasnici su primijetili malu tvorbu, oteklinu na desnoj lopatici koju je veterinar ignorirao. Tvorba se s godinama poveÄavala do veliÄine od 9 cm u promjeru, a pas je povremeno Å”epao. Nakon kliniÄkog i ortopedskog pregleda te rendgenografskog oslikavanja desne lopatice posumnjalo se na neoplaziju lopatice. PreporuÄena je biopsija i histopatoloÅ”ka pretraga tvorbe kako bi se potvrdila sumnja na osteosarkom. HistopatoloÅ”ki nalaz upuÄivao je na vrlo produktivan, osteoblastiÄni osteosarkom desne lopatice s pluÄnim metastazama. Prognoza je bila nepovoljna zbog rendgenografski dokazanih metastaza na pluÄima Kao Å”to je ovdje opisano, trauma može biti okidaÄ za razvoj spororastuÄeg periostalnog osteosarcoma, a pravilno dijagnosticiranje treba temeljiti na kliniÄkom pregledu, rendgenografskoj procjeni procesa i histopatoloÅ”kom nalazu. LijeÄenje osteosarkoma lopatice Äesto ukljuÄuje potpunu skapulektomiju ili amputaciju prednje noge s odgovarajuÄom kemoterapijom. UnatoÄ agresivnom lijeÄenju, skapularni osteosarkom ima loÅ”u prognozu, s niskim srednjim vremenom preživljenja i kratkim razdobljem bez bolesti u pasa. Nažalost, vlasnici mopsa odbili su preporuÄeno lijeÄenje i pas je nakon dva mjeseca eutanaziran
Causes of Achilles tendon inflammation in animals
Uzroci upala Ahilove tetive u životinja mogu biti traumatske i atraumatske prirode. PatoloÅ”ke promjene u smislu upale mogu se dogoditi na Äitavoj tetivi, bilo na prijelazu prema miÅ”iÄu, na samoj ovojnici bilo na hvatiÅ”tu Ahilove tetive za petnu kost. Etiologija upalnog procesa u samoj tetivi raznovrsna je, najÄeÅ”Äe je traumatske, odnosno mikrotraumatske, metaboliÄke i, rjeÄe, infektivne prirode. Djelovanjem razliÄitih Äimbenika, poput citokina interleukina-1, prostaglandina, duÅ”ikova oksida i metaloproteinaza, nastaje degradacija staniÄne i vlaknaste strukture tetiva. Degradacija je okarakterizirana kao slabljenje biomehaniÄkih svojstava tetive te smanjenje elastiÄnosti uz poveÄanu plastiÄnost i krutost te promjene u gustoÄi i debljini kolagenih vlakana koja postaju tanja. Nastaju promjene u sastavu i omjeru kolagena te izgledu vlakana karakteristiÄne za tendinopatije. Poznavanje etiologije i Äimbenika nastanka upale Ahilove tetive u životinja važno je za pravodobno prepoznavanje znakova upale, spreÄavanje nastanka kroniÄnog oblika upala i njihovo lijeÄenje. Za uspjeÅ”no i brzo lijeÄenje upale tetive lijeÄenje treba zapoÄeti u Å”to ranijoj fazi. Ako upalno stanje traje, nastaju oÅ”teÄenja, a upala prelazi u subakutni ili kroniÄni oblik. U sluÄaju da upala prelazi na hvatiÅ”te tetive, nastaje upalno stanje ā entezitis. Tkivo takve tetive je degenerativno promijenjeno i slabije opskrbljeno krvlju. Uz nakupljanje stranih tvari, poput kalcijevih soli, stvaraju se kalcifikati. Tetiva gubi svoju karakteristiÄnu histoloÅ”ku graÄu i biomehaniÄka svojstva, a svaki pokret postaje izvor bola. U ovom je radu sažeto prikazana problematika tendinopatija Ahilove tetive u životinja.Causes of Achilles tendon injury in animals can be traumatic or atraumatic. Pathological changes in relation to inflammation may occur throughout the entire tendon, either at the transition towards the muscle, on the tendon sheath itself, or on the Achilles tendon insertion into the back of the heel bone. The etiology of the inflammatory process in the tendon itself is diverse, most commonly itās traumatic, that is, microtraumatic, metabolic and less common infective. By the action of numerous factors such as cytokine interleukin-1, prostaglandin, nitric oxide and metalloproteinase, the cellular and fibrous structure of the tendon is degraded. Degradation is characterized as the weakening of biomechanical tendon properties and reduced elasticity while plasticity and stiffness are being increased. Changes in thickness and density of collagen fibres occurs and fibres are becoming thinner. Composition changes, collagen ratio and appearance of the fibres are characteristic of tendinopathies. Knowing the etiology and the cause of the Achilles tendon inflammation in animals is important for timely recognition of signs of inflammation, prevention of chronic inflammation and successful treatment. For successful and quick treatment of tendon inflammation it is crucial to start treatment in the early stage. If the inflammatory condition lasts it causes damage and inflammation passes into a subacute or chronic form. In case when inflammation transits on the Achilles tendon insertion it forms inflammatory state, called enthesitis . The tissue of such tendon has been degenerately changed, less supplied with blood, with the accumulation of foreign substances such as calcium salts and calcifications. Tendon loses its characteristic histological structure and biomechanical properties, and each movement becomes a source of pain. This paper summarizes the problems of Achilles tendon tendinopathy in animals
Mnemonic evaluation of osteosynthesis in dogs and cats
KoÅ”tani sustav životinja jest Ävrsti dio lokomotornog sustava te sa skeletnim miÅ”iÄjem sudjeluje u kretanju organizma i pruža zaÅ”titu srediÅ”njem živÄanom sustavu. S obzirom na to da je koÅ”tani sustav izložen raznim mehaniÄkim silama, Äesto dolazi do ozljeda koje rezultiraju prekidom kontinuiteta kosti ili hrskavice, odnosno lomom. VeÄina tih ozljeda zahtijeva operacijsko lijeÄenje odnosno osteosintezu. Rendgensko snimanje mjesta prijeloma treba napraviti prije operacije, odmah nakon operacije te u redovitim vremenskim razmacima poslije operacije kako bi se nadziralo stanje i napredak pacijenta te na vrijeme reagiralo ako cijeljenje kosti izostane ili bude usporeno. Za analizu i praÄenje cijeljenja prijeloma nakon osteosinteze te uspjeÅ”nosti osteosinteze primjenjuje se 4A metoda kojom promatramo sljedeÄe Äimbenike: poravnavanje fragmenata (Alignment), apozicija fragmenata (Apposition), stanje implantata (Apparatus) i aktivnost kosti (Activity). U ovom je radu opisana 4A mnemoniÄka procjena osteosinteze u nekoliko kliniÄkih sluÄajeva.The skeletal system of animals is the solid part of the locomotory system and together with the skeletal muscles, it participates in the movement of the organism and provides protection to the central nervous system. Due to the fact that the skeletal system is exposed to various mechanical forces, injuries often occur which result in breaking of the continuity of bone or cartilage, i.e. fractures. Most of these injuries require treatment or osteosynthesis. Radiology of the fracture should be performed before surgery, immediately after, and at regular intervals after surgery, in order to properly monitor the patient\u27s condition and progress and to promptly respond promptly if bone healing is not progressing or has slowed down. For analysis and monitoring of fracture healing after osteosynthesis and the success of osteosynthesis, the 4A method is used to observe the following factors: Aligment, Fragment Apposition, Apparatus, and Activity. This paper describes a 4A mnemonic evaluation of osteosynthesis through several case study examples
Usporedba pokazatelja procjene boli u pasa s operacijskim lijeÄenjem puknuÄa prednjeg križnog ligamenta
The objective of this study was to compare postoperative pain, as assessed by multiple objective and subjective methods, after Tibial Tuberosity Advancement and Modified Retinacular Imbrication Technique, procedures that differ significantly in the extent of the operative trauma. We compared the preoperative, 2, 6, 10, 20, 44 and 68-hour postoperative results of the University of Melbourne Pain Scale and visual analogue scale with the dynamics of the physiologic, biochemical and behavioural parameters. The integration of various parameters increases the objectivity of pain assessment. The invasiveness of the surgical technique does not necessarily correlate with the level of postoperative pain.Cilj ovog istraživanja bila je usporedba poslijeoperacijske boli, procijenjene viÅ”estrukim objektivnim i subjektivnim metodama, nakon kranijalne transpozicije goljeniÄne kvrge i modificiranog postupka zatezanja retinakula, kirurÅ”kih zahvata koji se prema opsegu operacijske traume znatno razlikuju. Usporedili smo rezultate bodovnog sustava intenziteta boli SveuÄiliÅ”ta u Melbourneu i vizualne analogne skale s dinamikom fizioloÅ”kih, biokemijskih i bihevioralnih pokazatelja prije operacije te 2, 6, 10, 20, 44 i 68 sati poslije operacije. Objedinjavanje razliÄitih pokazatelja poveÄava objektivnost procjene boli. Invazivnost operacijske tehnike ne mora se nužno podudarati sa stupnjem poslijeoperacijske boli
Complications of fracture healing in dogs and cats
Prilikom odabira lijeÄenja loma kosti potrebno je uzeti u obzir stanje životinje (dob, tjelesna masa i zdravstveno stanje), vrstu loma te financijsko stanje i angažman vlasnika. Zbog raznih uzroka, na koje se može ili ne može utjecati, može doÄi do komplikacija cijeljenja kosti, poput odgoÄenog cijeljenja, pseudoartroze ili nesrastanja, nepravilna srastanja, osteomijelitisa, sekvestracije, kutne deformacije te komplikacije cijeljenja zbog utjecaja implantata. Svako cijeljenje prijeloma dulje od oÄekivanoga naziva se odgoÄeno cijeljenje, a uzroci mogu biti neadekvatna fiksacija fragmenta, nedovoljna vaskularizacija kosti i okolnoga mekog tkiva, starost i drugi. Nesrastanje se odnosi na prijelome kod kojih nisu prisutni znakovi osteogenetske aktivnosti te je za sanaciju tih prijeloma potrebna kirurÅ”ka intervencija. Možemo ih klasificirati u dvije skupine: bioloÅ”ki aktivne i bioloÅ”ki neaktivne. Nepravilno srasli lomovi jesu oni u kojima fragmenti kosti tijekom cijeljenja nisu bili anatomski poravnati. Vrste nepravilnog srastanja su valgus, varus, translacijsko nepravilno srastanje, rekurvatum, antekurvatum i torzijsko nepravilno sraÅ”tavanje. Osteomijelitis je infekcija kosti koja ukljuÄuje Haversove i Volkmanove kanale, te uglavnom medularni kanal i periost. Može nastati zbog otvorenog prijeloma, ali i zbog nekih trauma. Sekvestar je avitalan ulomak kosti koji se izolirao procesom nekroze i okružen je eksudatom, koji može biti ili sterilan ili neinficiran. Kutna deformacija nastaje nakon traume fize kod životinja koje nisu zavrÅ”ile rast, kao posljedica preranog zatvaranja dijela ili Äitave zone rasta te zaustavljanja rasta tog dijela kosti. U ovom Äemo radu pobliže objasniti svaku od komplikacija i njihove uzroke.When choosing a method of fracture repair, patient considerations (such as age, weight, overall general health), type of fracture and the ability of the owner to perform postoperative care, and the financial status of the owner should all be carefully considered. For various reasons that may or may not be preventable, complications of fracture treatment may be observed, such as delayed union, non-union, malunion, osteomyelitis, sequestration, angular deformities and implant failure. A delayed union is a fracture that takes longer to heal than anticipated. Causes may be inadequate fracture ļ¬xation, inadequate vascularity of the bone and soft tissue, the patient\u27s age, etc. A nonunion is a fracture that has failed to heal, and does not show any further signs of progression towards consolidation. Nonunions may be classified as biologically active (viable), and biologically inactive (nonviable). Malunions are healed fractures in which anatomical bone alignment was not achieved or maintained during healing. Malunions include: deviations in the limb axis (angular deformities), rotational limb deformities and shortening of the limb. Osteomyelitis is defined as a bone inflammation involving the Haversian spaces, Volkmann canals, and generally the medullary cavity and periosteum. Bone infection is usually associated with open fractures or other trauma. Sequestra are, by definition, dead bone fragments separated from a blood supply, that may be associated with infection. Angular deformities appear after physeal fractures as a result of injury to the growth plate. This paper explains each of the complications of fracture repair and their causes
