Metacarpophalangeal (MCP) joint extension is primarily resisted by the digital flexor tendons and suspensory ligament. A variety of external support techniques are used to protect these supporting structures from or after injury by resisting MCP joint extension, although not all are effective and/or practical for use in an exercising horse. In this study, 7 forelimbs were loaded in vitro to determine the effect of a simple gamgee bandage, a 3-layered bandage with and without a contoured palmar splint, a neoprene exercise boot, and an innovative carbon fibre composite exercise boot (Dalmar tendon support boot). There was no significant resistance to MCP joint extension by the gamgee or neoprene exercise boot. The 3-layered bandage had a significant (P<0.01) supporting effect at MCP angles of > or = 245 degrees, and when combined with the contoured splint at angles of > or = 230 degrees. The Dalmar tendon support boot resisted MCP extension at angles of > or = 245 degrees (settings 1 and 2) and > or = 225 degrees (setting 3). These data demonstrate that the contoured splint and the Dalmar tendon support boot (which is also easily fitted for use during exercise) are useful for the management of tendon/ligament injury and during rehabilitation.
掌指关节（MCP）伸展主要受指屈肌腱和悬韧带的抵抗。人们采用了多种外部支撑技术，通过抵抗MCP关节伸展来在损伤前或损伤后保护这些支撑结构，不过并非所有技术都对运动中的马匹有效和/或实用。在本研究中，对7个前肢进行体外加载，以确定单层粗棉布绷带、带或不带塑形掌侧夹板的三层绷带、氯丁橡胶运动靴以及一种创新的碳纤维复合运动靴（达尔马肌腱支撑靴）的效果。单层粗棉布绷带或氯丁橡胶运动靴对MCP关节伸展没有显著的抵抗力。三层绷带在MCP角度≥245°时具有显著（P<0.01）的支撑作用，与塑形夹板结合时在角度≥230°时也有支撑作用。达尔马肌腱支撑靴在角度≥245°（设置1和2）以及≥225°（设置3）时可抵抗MCP伸展。这些数据表明，塑形夹板和达尔马肌腱支撑靴（在运动期间也易于安装使用）在肌腱/韧带损伤管理和康复过程中很有用。
