Treatment of dicapitular fractures of the mandibular condyle with ultrasound activated resorbable pins—early clinical experience

Resorbable pins have been advocated for open reduction and internal fixation of dicapitular condylar fractures because they do not need to be removed should the fixation fail, or if the screw is overextended surgically or as a result of later remodelling. Ultrasound activated resorbable pins produce less compression forces during insertion, reducing the risk of splitting of the small proximal condylar fragment. We have now treated 4 patients with unilateral dicapitular fractures of the condyle with ramus shortening, ranging in age from 19 to 66, by open reduction and internal fixation with this technique. Fixation of the condylar head was performed with ultrasound-activated poly-( d , l )-lactide resorbable pins (KLS Martin SonicWeld Rx ® ) using 2.1 mm diameter, 15 mm length screws. Follow up ranges from 2 to 6 months. Post-operatively all patients have returned to normal mandibular movements within 2 months. None reported symptoms of temporomandibular dysfunction. There was one patient with temporary palsy of the frontal branches of the facial nerve. There were no other intra- or post-operative complications. On the basis of our preliminary experience we advocate the use of ultrasound activated resorbable pins for the fixation of dicapitular fracture of the mandibular condyle with ramus shortening.
