ANKLE FIXATION SYSTEM

摘要

A clamping assembly (108) includes a longitudinal member (162) having a first end (164) and a second end (166), the second end defining a first clamp (168), a second clamp (170) configured to attach to the first end of the longitudinal member and connect to a rod assembly (106), a clamping member (176) including a first end (178), a second end (180) defining a spherical portion (190) which can be configured to expand, and a third clamp (182), where the first clamp of the longitudinal member is configured to receive the spherical portion of the second end of the clamping member to form a polyaxial joint. The clamping assembly can be a metatarsal bone pin clamping assembly of an external fixation system, for example for immobilizing an ankle joint.
