A number of studies have demonstrated that dorsal cortical comminution (DCC) can predict redisplacement after nonoperative treatment of Colles’ fractures; however, the effects of a DCC defect on radiographic outcomes following percutaneous pinning for dorsally displaced extraarticular Colles’ fractures are unclear. We, therefore, performed a retrospective study on 85 patients who sustained such fractures treated with percutaneous pinning within 2006–2009. The main outcome measures included four radiographic parameters, including radial height, radial inclination, radial tilt, and ulnar variance. The radiological results showed that all fractures after percutaneous pinning followed the same time series changes and patterns of fracture collapse regardless of the presence of a DCC defect. The use of the pinning construct is to provide support for static loading but not for dynamic loading. Although the final radiographic outcomes were classified as acceptable in fractures with and without DCC, we recommend that a different approach in the management of displaced Colles’ fractures might be necessary in consideration of increasing patient expectations of health care.
