The present study was undertaken to determine the influence of the peroneus tertius muscle on the loading regime of the tibia in the horse. Strain gauge rosettes were bonded to the cranial and caudal cortices of the left and right tibiae in six Shetland ponies. In vivo bone strain recordings were made before and after unilateral transection of the peroneus tertius muscle. Relatively large individual variations in response to transection were observed in both the experimental and the contralateral control limbs. The principal strain values on the cranial and caudal cortices increased during the second peak in the support phase by approximately 10 per cent; the angle between the larger principal strains and the long axis of the bone, measured proximal to the gauges, rotated approximately 4 degrees medially in experimental limbs, but did not change in the control limbs. It seems unlikely that the peroneus tertius muscle has a substantial influence on the loading regime of the tibia during normal walking.
本研究旨在确定第三腓骨肌对马胫骨负荷状态的影响。在6匹设得兰矮种马中，将应变片花粘贴到左右胫骨的颅侧和尾侧皮质上。在单侧切断第三腓骨肌之前和之后进行体内骨应变记录。在实验侧肢体和对侧对照肢体中均观察到对切断反应的相对较大的个体差异。在支撑相的第二个峰值期间，颅侧和尾侧皮质上的主应变值增加了约10%；在应变片近端测量的较大主应变与骨长轴之间的角度在实验侧肢体中向内侧旋转了约4度，而在对照肢体中没有变化。在正常行走过程中，第三腓骨肌似乎不太可能对胫骨的负荷状态产生实质性影响。
