The flexor digitorum profundus tendons are markedly interconnected, making them less able to move independently than the tendons of the flexor digitorum superficialis. This difference is often attributed to the common muscle belly of the profundus, but also, more importantly, to cross-connections between the tendons of the profundus. The effect of this quadriga phenomenon is important in several clinical situations, including testing for strength, assessing movement of the tendons, and when deciding which exercises to teach the patient after a tendon injury. The anatomy and biomechanics of this phenomenon are reviewed in this article to help explain why certain conditions occur, and to improve the diagnosis and treatment of some conditions in rehabilitation medicine.
指深屈肌腱明显相互连接，这使得它们比指浅屈肌腱更难以独立移动。这种差异通常归因于深屈肌的共同肌腹，但更重要的是，归因于深屈肌腱之间的交叉连接。这种“四肌腱现象”的影响在几种临床情况下很重要，包括力量测试、评估肌腱运动以及在肌腱损伤后决定教给患者哪些锻炼方法时。本文回顾了这一现象的解剖学和生物力学，以帮助解释某些情况为何会发生，并改善康复医学中某些病症的诊断和治疗。
