Pseudo-arthrosis repair of a posterior cruciate ligament avulsion fracture.

Hoogervorst P, Gardeniers JW, Moret-Wever S, van Kampen A - Knee Surg Sports Traumatol Arthrosc (2010)

Bottom Line: A pseudo-arthrosis repair of a 4-year-old bony avulsion fracture of the PCL using a minimally invasive technique, screw fixation, and bone grafting is reported.The case presented seems to be rather unique due to the fragment size and the approach for pseudo-arthrosis repair.Therefore, refixation and pseudo-arthrosis repair should be considered as a viable treatment.

ABSTRACT
A pseudo-arthrosis repair of a 4-year-old bony avulsion fracture of the PCL using a minimally invasive technique, screw fixation, and bone grafting is reported. The case presented seems to be rather unique due to the fragment size and the approach for pseudo-arthrosis repair. There was a good functional result following minimally invasive pseudo-arthrosis repair of a posterior cruciate ligament avulsion fracture. There are no previous reports of similar pseudo-arthrosis repairs, and other authors report good results of delayed refixation of PCL avulsion fractures. Therefore, refixation and pseudo-arthrosis repair should be considered as a viable treatment.

Mentions: Using a curette through the drill-hole, the remaining pseudo-arthrosis was removed under fluoroscopic control (Fig. 4). A combination of the removed cancellous bone mixed with homologous bone was used to fill the defect created by the cannulated drill. Fluoroscopic imaging showed good positioning of the bone grafting. A tibial ACL guide was used to guide Kirschner wires for two 4.5-mm cannulated partially threaded screws. These screws were used to lag and stabilize the bony fragment.Fig. 4
