摘要 |
The acromioclavicular joint prosthesis of the present invention provides a mechanism for securing the distal or outer end of the clavicle to the acromion of the scapula. The present prosthetic device includes an acromion attachment component, an opposite clavicle attachment component, and an articulated joint between the two components. The intermediate joint may include a "breakaway" component, allowing the joint to be temporarily misaligned in the event that a severe force is applied to the shoulder, rather than damaging the joint or shoulder structure. The breakaway joint may be quickly and easily realigned by a medical professional. The joint may also include a spring loaded shock absorption component as well, to avoid damage to the joint due to excessive tensile forces. Tools and a method for surgically installing and locking the present prosthesis securely to the respective bones of the skeletal structure, are also disclosed.
