Complications following palmar plate fixation of distal radius fractures: a review of 665 cases.

INTRODUCTION

Palmar plate fixation of unstable distal radial fractures is quickly becoming the standard treatment for this common injury. The literature reporting complications consists mainly of isolated case reports or small case series.

METHOD

Between February 2004 and December 2009 palmar plate fixation was performed in 665 cases. The overall complication rate was 11.3 % (75 complications). Revision surgery was necessary in 10 % (65 procedures).

RESULTS

The reasons for revision surgery were: postoperative median nerve compression (22 patients) and secondary dislocation (9 patients). An ulna shortening osteotomy for ulnar impingement syndrome was necessary in eight cases. Intraarticular screw placement occurred in three patients. There were two flexor pollicis longus, one finger flexor and three extensor pollicis longus tendon ruptures. Posttraumatic compartment syndrome of the forearm requiring fasciotomy occurred in four cases. There were three cases of infection. Nonoperative treatment was necessary in nine patients, who developed a complex regional pain syndrome. Hardware failure occurred in three cases. Hardware removal was performed in 232 (34 %) cases.

CONCLUSION

Palmar plate fixation of distal radius fractures is a safe and effective procedure. Nevertheless, complications necessitating a second intervention are relatively common. A proportion of these complications is iatrogenic and can be avoided by improving the surgical technique.
