內容說明

Stifle instability

常見後肢跛行，尤其在較重的牛隻 Common hind limb lameness esp in heavy animals
在公牛常見於托架損傷 A common mounting injury in bulls
可能與十字韌帶損傷、側副韌帶斷裂、1或2個半月板損傷(撕裂等)，或股-脛骨關節完全脫位有關 May be associated with damage to the cruciate ligaments, rupture of the collateral ligaments, injuries to one or both menisci (tears etc) or complete dislocation of the femoro-tibial joint

膝關節站不穩 - 臨床症狀Stifle instability - clinical signs

Ø步伐縮短 Shortened stride

Ø負重在腳趾 Weight bearing on the toe

Ø壓抑而限制運動 Restricted movement of the stifle

通常可以觸診，有時後能聽見後膝關節有咚咚聲 Can usually palpate, hear (and sometimes see) a clunk over the stifle
為了檢測“關節的咚咚聲”，讓動物鎮定並走到牠旁邊，以你的手去感覺關節處 To detect the ‘clunk’, mild sedation and walk animal around the yard whilst feeling the joint with your hand
通常無明顯腫脹或伴有關節疼痛 Often no obvious swelling or pain associated with the joint

處置Stifle instability - treatment -膝關節站不穩治療

傳統治療及讓動物多休息 Conservative treatment and prolonged rest
畜主若忽略患畜肢體關節的聲音而給予額外的壓力，可能會讓動物崩潰 Warn owner joint on sound limb may collapse under additional pressure
預後的將來，在公牛的育種上需非常謹慎 Prognosis for future breeding soundness for a bull is very guarded
通常建議淘汰 Culling is often recommended
