| 中文描述 | 腓腸肌肌腱炎會引起馬匹跛腳.這樣會減少踝關節的彎曲度,降低抬腳時的弧度,以及會縮短跨步的前期距離,而在某些馬會在跨步的後期時減少負重的時間.會在腓腸肌的區域有輕微到中度的腫脹,在某些馬會有熱感,但肌腱觸診時無痛.有些馬發展出一種”加蓋踝關節”外觀.從超音波上看,腓腸肌的橫截面區域是擴大的,伴隨粗劣分辨的一或多個空白和一個減弱的回音強度區域.阻斷腓股和脛骨神經或單獨脛骨神經所引發的局部痛覺缺失導致步態的改善.初始檢查後2-3個月馬匹仍為跛腳. |

| 英文描述 | Gastrocnemius tendinitis caused lameness in horses. There was reduced hock flexion, lowered arc of foot flight, shortened length of the cranial phase of the stride, and in some horses a reduced duration of weight bearing during the caudal phase of the stride. There was mild to moderate enlargement in the region of the gastrocnemius, with associated heat in some horses, but no pain on palpation of the tendon. Some horses developed a 'capped hock' appearance. On ultrasonography the cross-sectional area of the gastrocneumius was enlarged, with poor definition of one or more margins and an area of decreased echogenicity. Local analgesia caused by blocking the fibular and tibial nerves or the tibial nerve alone resulted in improvement of the gait. Horses remained lame 2-3 months after initial examination. |
