Abstrakt
Mediaalne põlvekedra paigaltnihkumine (patella luksatsioon) on tavaline, peamiselt
kaasasündinud ortopeediline haigus, mis on probleemiks kõikidele koertele, eriti aga
kääbus ja väiksetel tõugudel. Selle haiguse kogu patogenees ei ole veel selge aga enamikul
koertest esineb sarnaseid lihaste ja skeleti anomaaliaid tabandunud tagajäsemes.
Selle uurimuse eesmärkiks oli hinnata röntgenpiltidelt reieluu nurkasid ja nende nurkade
suuruse erinevusi normaalsete põlvedega (Putnami skaalal 0/0) ja patella luksatsiooniga
(Putnami skaalal 1-2) Lancashire’i heelerite vahel. Kokku mõõdeti ja analüüsiti 75
tagajäset. Kirjeldavad andmed koerte kohta koguti Soome Kennelliidu andmebaasist. Kõik
mõõtmised röntgenpiltidelt tegi töö autor teadmata mõõdetavate jalgade patella
luksatsiooni kraadi.
Tulemused näitasid statistiliselt oluliselt (p < 0,05) suuremad reieluu varus nurgad (FVA),
reieluu pea kalduvuse nurk (IFA) ja anatoomiline lateraalse distaalse reieluu nurgad
(aLDFA) koertel kellel on mediaalne põlvekedra nihestus. Ka mehhaaniline lateraalne
distaalne reieluu nurgad (mLDFA) oli suuremad aga see tulemus oli vaid lähedane
statistilisele olulisusele (p = 0,055). Teistes mõõdetud parameetrites ei esinenud olulist
erinevust tervete ja patella luksatsiooniga jalgade vahel. Samuti ei esinenud seost ühegi
mõõdetud parameetri ning koera vanuse, soo ega ka tagajala poole vahel.
Medial patellar luxation (MPL) is a common, usually considered a congenital orthopedic disorder in all dogs, especially toy, miniature and small breed dogs. The entire pathogenesis of this condition is not clear but most of the animals are presented with some form of musculoskeletal abnormalities in the affected limb. The aim of this study was to evaluate in general and investigate the correlation between the magnitude of radiographic femoral angle measurements in Lancashire Heelers that have normal (Putnam grades 0/0) patellae and the ones with MPL (Putnam grades 1-2). Total of 75 pelvic limbs were measured and analyzed. Results demonstrated a statistically significant (p < 0,05) larger femoral varus angles (FVA), inclination of the femoral head angles (IFA) and anatomical lateral distal femoral angles (aLDFA) in the MPL group. According to the results, mechanical lateral distal femoral angles (mLDFA) were also larger but the result was not statistically significant, even though it approached it (p = 0,055). No significant difference was found in other measurement values. No association with the magnitude of the measurements to the dogs’ age, gender or the side of the limb was found.
