title: Isolated intra-articular fracture of the distal ulna: a rare injury related to airbag deployment.
abstract: An isolated intra-articular and adjacent shaft fracture of the distal ulna is described. A 38-old-year woman driver sustained an automobile accident with subsequent airbag deployment injuring her left wrist. Imaging studies showed displacement of a radiovolar fragment and deformity of the ulnar articular surface. The fracture was reduced and internally fixed with 3, 3.5-mm, cannulated screws to avoid future difficulties in forearm rotation, ulnocarpal impaction, and late posttraumatic arthritis. The final outcome was excellent. Careful clinical and radiologic examination is strongly recommended for this type of fracture, which seems to be a part of the spectrum of upper limb injuries associated with airbag deployment. Such injuries can be expected to occur more frequently with the increasing use of airbags.
