Review of 121 bone scintigrams obtained on racing Thoroughbred horses with clinical histories indicative of forelimb lameness revealed 3 scintigraphic patterns of stress-induced trauma to the dorsal cortex of the third metacarpal bone: (1) focal, intense uptake associated with recent stress fracture; (2) regional uptake of varying intensity or a mixed pattern of uptake associated with chronic stress fracture; and (3) diffuse, mild to moderate uptake associated with periostitis (bucked shins). The latter scintigraphic pattern appeared to be an exaggerated manifestation of the normal remodeling process evident in immature horses (2 to 3 years old). Scintigraphy was most helpful in identifying radiographically occult stress fractures, determining the extent of cortical involvement before surgical intervention in cases of chronic stress fractures, and monitoring the fracture healing process.
对121匹有前肢跛行临床病史的纯种赛马的骨闪烁显像图进行回顾分析，发现第三掌骨背侧皮质因应力性创伤出现3种闪烁显像模式：（1）与近期应力性骨折相关的局灶性、强烈摄取；（2）与慢性应力性骨折相关的不同强度的区域性摄取或混合摄取模式；（3）与骨膜炎（胫骨酸痛）相关的弥漫性、轻度至中度摄取。后一种闪烁显像模式似乎是2至3岁未成熟马匹正常重塑过程的一种夸张表现。闪烁显像在识别X线隐匿性应力性骨折、确定慢性应力性骨折病例手术干预前皮质受累程度以及监测骨折愈合过程方面最有帮助。
