Keller arthroplasty: is distraction a useful technique? A retrospective study

A retrospective study comparing advantages of single or crossed intramedullary Kirschner wire fixation versus straight Keller arthroplasty is reported. The results suggest that the use of distractors weakly correlates with increase in both range of motion and overall patient satisfaction. It appears this correlation is related to temporary increase in joint space, which accordingly leads to increased fibrosis in the early postoperative stages, allowing for a better joint space and functional result.
