UPPER LIMB PROSTHETICS-F. CONTROL CABLE SYSTEMS

SUMMARY

1. Consists of a flexible, stranded stainless-steel cable which slides within a flexible housing. The cable is attached proximally at the harness and distally at the elbow or terminal device.

2. The single-control cable system (Bowden cable system): muscle movements used to operate the terminal device are forward humeral flexion and biscapular abduction.

3. The dual-control cable system (split cable or fair lead cable system): is typically used in the transhumeral control-cable system as well as in the very short transradial split-socket prosthesis with locking hinge.
- Consists of one cable with two functions: flex the elbow unit when the elbow is unlocked; operates the terminal device when the elbow is locked.
