Background: Ulnar shortening is a common and useful method for treating ulnar wrist pain from many causes. Many devices used to perform osteotomy have been introduced in the literature; however, the devices are not universally available. The standard freehand technique is still commonly used in clinical practice; however, it is associated with several complications and is time-consuming. We present a freehand technique for ulnar-shortening osteotomy using a predrilled hole method.
Methods: From 2011 to 2013, we performed the predrilled hole method for ulnar shortening in 18 cases using the six-hole limited-contact dynamic compression plate (LC-DCP) and in two cases using the Acumed six-hole Locking Midshaft Ulna Plate.
Results: All patients had uneventful union, and the average operative time was 39.7 minutes (range, 32-50 minutes). The average follow-up period was 21 months (range, 12-30 months). There were no complications except in three patients in the LC-DCP group who complained of implant irritation. Good functional outcomes were achieved with this method.
Conclusion: Our technique is easy and quick to use and can minimize soft-tissue manipulation. The union rate is high and complications are few.
