The objective of this work was to study the normal musculotendinous structures of the ostrich foot.
Ten African apparent healthy adult female ostriches () were slaughtered, and the pelvic limbs were separated from the ankle joint. The different biomedical scanning techniques including radiography, computed tomography (CT), magnetic resonance imaging, and ultrasonography were achieved. Then, the ostrich feet were freshly dissected.
The radiographs and CT images showed the bony components of the ostrich foot that revealed the presence of long tarsometatarsus and phalanges of the only developed third and fourth toes. The third digit was the longest and possessed four phalanges, whereas the shorter fourth toe contained five phalanges. The ostrich foot consisted mainly of tendons in addition to several small associated muscles. The extensor structures were the extensor digitorum longus tendon, Mm. extensor proprius digiti III, and extensor brevis digiti III and IV. On the other hand, the flexor structures were the flexor digitorum longus, flexor hallucis longus, flexor perforans et perforatus digiti III, and flexor perforatus digiti III and IV tendons. Furthermore, fibularis longus tendon and two muscles (Mm. abductor digiti IV and lumbricalis) were related to the flexor tendons.
The combination between the dissecting anatomy and the different biomedical scanning techniques was of value in describing the normal anatomical course of the musculotendinous structures of the ostrich foot, which aids in the diagnosis of any clinical abnormalities in these structures.
本研究旨在探究鸵鸟足部正常的肌肉肌腱结构。
选取10只表面健康的成年非洲雌性鸵鸟进行屠宰，将其骨盆肢从踝关节处分离。运用了包括X线摄影、计算机断层扫描（CT）、磁共振成像及超声检查在内的不同生物医学扫描技术。随后，对鸵鸟足部进行新鲜解剖。
X线片和CT图像显示了鸵鸟足部的骨骼组成部分，揭示了发达的第三和第四趾存在长跗跖骨和趾骨。第三趾最长，有四块趾骨，而较短的第四趾有五块趾骨。鸵鸟足部除了几块与之相连的小肌肉外，主要由肌腱构成。伸肌结构包括趾长伸肌腱、第三趾固有伸肌、第三和第四趾短伸肌。另一方面，屈肌结构包括趾长屈肌、拇长屈肌、第三趾屈肌穿孔腱和第三、四趾屈肌穿孔腱。此外，腓骨长肌腱以及两块肌肉（第四趾展肌和蚓状肌）与屈肌腱相关。
解剖学与不同生物医学扫描技术相结合，对于描述鸵鸟足部肌肉肌腱结构的正常解剖路径具有重要价值，有助于诊断这些结构的任何临床异常情况。
