Dynamic skeletal fixation in the upper extremity.

Recent advances in the understanding of the biomechanics of the elbow and improvement in material designs have revolutionized the ability to treat difficult problems of the proximal interphalangeal and elbow joints. Dynamic skeletal fixation addresses the desire to allow an injured joint to heal, move, and remain stable simultaneously. In the past, such goals were achieved sequentially or in series. It is now possible to perform such tasks in parallel.
