Stenosis lumbosakral degeneratif menyempitkan kanal di L7–sakrum, tempat akar cauda equina lewat. Kompresi menyebabkan nyeri, peradangan, dan defisit neurologis.

Penyebab dan faktor risiko

Utamanya degeneratif: diskus L7–S + ketidakstabilan + penebalan faset, kapsul, dan ligamen kuning. Umum pada anjing besar aktif; predisposisi pada German Shepherd Dogs, Belgian Malinois, dan Labrador Retrievers.

Tanda yang perlu diwaspadai

Utama

  • Nyeri pada palpasi dalam sakrum; nyeri pada dorsifleksi ekor atau hiperekstensi lumbar

Umum

  • Enggan berlari, melompat, naik tangga; pincang belakang; bangkit lambat

Sesekali / merah

  • Kelemahan belakang, ekor rendah, atrofi, refleks berubah; tonus anus menurun, inkontinensia, trauma diri perineum

Diagnosis

Singkirkan diskospondylitis, penyakit prostat, dan OA. Tes klinis. Rontgen. MRI dalam ekstensi baku emas.

Pengobatan

Medis (lini pertama jika ringan)

Bedah

  • Laminektomi dekompresif jika obat gagal atau defisit progresif

Prognosis

Hanya pincang dan defisit ringan: sering sangat baik. Inkontinensia atau defisit berat: waspada hingga buruk. Keberhasilan bedah jangka panjang ~55 %.

Pencegahan

Berat ideal, olahraga low-impact, intervensi dini pada ras berisiko.

Kapan menghubungi dokter hewan

Kunjungan jika bangkit lambat, hindari tangga, atau ekor rendah. Darurat jika paresis belakang mendadak, inkontinensia, nyeri ekstrem, atau jilat agresif pangkal ekor/selangkangan.

Untuk ras tertentu
