[Distraction arthrolysis with humero-ulnar motion fixator]

Distraction arthroplasty in the treatment of elbow stiffness with an external fixator and subsequent fixator assisted mobilization is described. Joint distraction is employed to correct the shortened ligaments and capsule and permits the separation of articular surfaces. After intraoperative joint distraction, a phase of relaxation followed by fixator assisted mobilization is carried out. The use of the motion fixator is described and additional measures discussed. This technique is particularly valuable in joint subluxation or persistent joint dislocation and allows for reduction after distraction in order to secure joint congruity. Postoperative management is a key factor for the success of the management protocol.
