Ukratko

Lumbosacral stenosis is a common degenerative spinal condition in dogs that compresses the nerves at the base of the back. Learn to recognize the signs of pain, weakness, and mobility issues, and discover how veterinarians diagnose and treat this progressive disease.

TL;DR. Degenerativno suženje donjeg kralježničnog kanala s kompresijom živaca: bol, slabost i problemi s kretanjem.

Zahvaća lumbosakralni spoj.

Što je to?

Degenerativna lumbosakralna stenoza sužava kanal na L7–sakrumu gdje prolaze korijeni cauda equina. Kompresija uzrokuje bol, upalu i neurološke deficite.

Uzroci i čimbenici rizika

Uglavnom degenerativna: disk L7–S + nestabilnost + zadebljanje fasetnih zglobova, čahura i žutog ligamenta. Česta u velikih aktivnih pasa; predispozicija u German Shepherd Dogs, Belgian Malinois i Labrador Retrievers.

Znakovi na koje treba pripaziti

Glavni

  • Bol na dubokoj palpaciji sakruma; bol na dorzifleksiji repa ili hiperekstenziji lumbalnog dijela

Uobičajeni

  • Nevoljkost za trčanje, skakanje, stepenice; stražnje šepanje; sporo ustajanje

Povremeni / crveni

  • Stražnja slabost, nizak rep, atrofija, izmijenjeni refleksi; smanjen analni tonus, inkontinencija, samotrauma perineuma

Dijagnostika

Isključiti diskospondilitis, bolest prostate i artrozu. Klinički testovi. RTG. MR u ekstenziji zlatni standard.

Liječenje

Medicinski (prvi izbor ako blago)

Kirurški

  • Dekompresivna laminektomija ako lijekovi zakažu ili deficiti napreduju

Prognoza

Samo šepanje i blagi deficiti: često izvrstan. Inkontinencija ili teški deficiti: oprezan do loš. Dugoročni kirurški uspjeh ~55 %.

Prevencija

Idealna težina, low-impact kretanje, rana intervencija kod rizičnih pasmina.

Kada zvati veterinara

Pregled pri sporom ustajanju, izbjegavanju stepenica ili niskom repu. Hitno pri iznenadnoj stražnjoj parezi, inkontinenciji, ekstremnoj boli ili agresivnom lizanju baze repa/prepona.

Za određene pasmine

Posebna budnost kod German Shepherd Dogs, Belgian Malinois i Labrador Retrievers.
