Nonunions following fracture fixation result in significant patient morbidity and financial burden. Traditional operative management around the elbow consists of removal of metalwork, debridement of the nonunion and re-fixation with compression, often with bone grafting. Recently, some authors in the lower limb literature have described a minimally invasive technique used for select nonunions where simply placing screws across the nonunion facilitates healing by reducing inter-fragmentary strain. To our knowledge, this has not been described around the elbow, where traditional more invasive techniques continue to be employed. The aim of this study was to describe the application of strain reduction screws for management of select nonunions around the elbow. We describe 4 cases (two humeral shaft, one distal humerus and one proximal ulna) of established nonunion following previous internal fixation, where minimally invasive placement of strain reduction screws were used. In all cases, no existing metal work was removed, the nonunion site was not opened, and no bone grafting or biologic stimulation was used. Surgery was performed between 9 and 24 months after the original fixation. 2.7 mm or 3.5 standard cortical screws were placed across the nonunion without lagging. Three fractures went on to unite with no further intervention required. One fracture required revision fixation using traditional techniques. Failure of the technique in this case did not adversely affect the subsequent revision procedure and has allowed refinement of the indications. Strain reduction screws are safe, simple and effective technique to treat select nonunions around the elbow. This technique has potential to be a paradigm shift in the management of these highly complex cases and is the first description in the upper limb to our knowledge. [ABSTRACT FROM AUTHOR] |
