We followed up 37 periprosthetic fractures to assess the factors related to the outcomes and the loosening of prostheses. The average union time is 3.1 months (range, 2-6.2 months). The most common types were fractures around the stem tip and displaced (89.1%). In our study, the loosening rate (32.4%) was low compared with other reports. These might be due to the cementless stem, but the difference was not significant (P>.05). After management of the fracture with a plate, we noted 5 complications: 2 nonunion and 3 refractures. The causes of these complications were related to screw in the level of the stem tip. Therefore, in the management of fractures with plates, we do not recommend using a screw in the area of the stem tip but rather using a cerclage proximally and bone graft. If stem was unstable or stability was uncertain, and the arthroplasty did not function well previously, revision with a distal fluted stem showed an early bony union.
