The operation of femoral non-union after IM(Intramedullary) nailing in distally femoral fractures is considered. Augmentive plate fixation is the management of femoral non-union after IM nailing. The purpose of this study is to compare the bending, torsional stiffness and stress distribution of the two operations by the FEM(Finite Element Method). Augmentive plate fixation is better than IM nail fixation. These results conclude that plate augmentation is a useful method for the unstable femoral non-union after interlocking IM nailing.

Purpose: To evaluate the clinical results of operative treatment of the intra-articular calcaneal fracture with injectable calcium sulfate ($MIIG^{TM}$). Materials and Methods: Between March 2004 and October 2006, a total 19 intra-articular calcaneal fracture (16 patients) with a large bony defect that underwent operative treatment with plate fixation and injectable calcium sulfate ($MIIG^{TM}$) with minimum follow-up of one year following. The mean age at time of surgery was 44.7 years (23 to 54). All of the cases were type 2 and 3 on the basis of Sanders classification. The lateral L shaped approach was used in all cases. Full weight bearing on the affected extremity was regained at an average 10 weeks postoperatively. Results: The mean Bohler angle was improved from $2^{\circ}$ ($-18.5{\sim}12.5^{\circ}$) preoperatively to $23.8^{\circ}$ ($12{\sim}37.5^{\circ}$) and the angle at last follow-up was $22.5^{\circ}$ ($11.5{\sim}37.5^{\circ}$), showing about 0.3 degree decline compared to postoperative Bohler angle. Only two case of whitish leakage of graft material but other complication were none. Conclusion: $MIIG^{TM}$ augumentation of displaced intra-articular calcaneal fracture with large bone defect seems to bo useful method for initial stabilized and plate fixation.
