A 10-yr-old male Masai giraffe (Giraffe camelopardalis tippelskirchi) presented with acute right forelimb lameness. Radiographs revealed a fracture of the medial claw of the distal phalanx penetrating into the distal interphalangeal joint. The giraffe was sedated while it was standing in a chute, and a wooden "hoof block" was applied to the lateral claw of the same limb. The animal was no longer lame 3 days after the procedure. Subsequent treatments included vitamin E, phenylbutazone, and glycosaminoglycans. For 7 wk it was maintained in a small holding yard on packed sand during the day and on deep sand during the night. The hoof block slowly wore down, and at 7 wk, it was placed back on concrete in the evening. At 8 wk, the block had completely worn off and the animal was no longer lame, but radiographs indicated minimal fracture healing. Radiographs performed at 7 mo indicated that there was still a radiolucent zone at the fracture line but calcification was evident at the margins of the fracture.
一只10岁的雄性马赛长颈鹿（Giraffe camelopardalis tippelskirchi）出现右前肢急性跛行。X线片显示远端指骨内侧爪骨折并穿入远侧指间关节。长颈鹿站在斜槽中时被麻醉，然后在同一肢体的外侧爪上安装了一个木制“蹄块”。术后3天，这只长颈鹿不再跛行。后续治疗包括维生素E、苯丁氮酮和糖胺聚糖。在7周的时间里，白天它被关在一个铺满压实沙子的小围场里，晚上则关在深沙里。蹄块慢慢磨损，7周时，晚上将其放回混凝土上。8周时，蹄块完全磨损，长颈鹿不再跛行，但X线片显示骨折愈合程度极小。7个月时进行的X线片显示，骨折线处仍有一个透光区，但骨折边缘有明显钙化。
