The proximal interphalangeal joints (PIPs) of the fingers are crucial for normal digital and hand function. Studies of their anatomy reveal subtle bony differences that dictate the precise planes of motion allowed in the constrained joint. Soft tissue restraints guide the cartilaginous surfaces through permissible ranges of motion. Understanding these restraints and the precise orientation of other joint structures assists treatment of conditions affecting the PIP joint.
手指的近端指间关节（PIP）对于正常的手指和手部功能至关重要。对其解剖结构的研究揭示了细微的骨质差异，这些差异决定了受限关节所允许的精确运动平面。软组织限制引导软骨表面通过允许的运动范围。了解这些限制以及其他关节结构的精确取向有助于治疗影响近端指间关节的病症。
