Abstract
PDF - PURPOSE
The purpose was to evaluate the postoperative periprosthetic femur fracture of hip arthroplasty and relative problems of management using plate fixation. MATERIAL AND METHOD: We reviewed 37 cases of femoral fractures out of 1,270 (1,183 primary hips and 97 revision hips) hips which received hip arthroplasty during the observation period (1985~1998). We classified them according to the stability and the location of the fractures related to the stem tip: Proximal (I), middle (around stem) (II) and distal (III). Then we subclassified the fractures as cortical perforation or a fissure, undisplaced (A), displaced (B) and unstable prosthesis (C). we managed periprosthetic fracture with splint applied or cerclage proximal fracture (type I), plate fixation and bone grafts in the stem tip (type II) or distal fracture (type III). In unstable fractures, we revised them with long fluted stems.
RESULT
The average union time is 3.1 months (range, 2~6.2 months). After management of fracture with plate showed 5 complications, two nonunion and three refractures. The causes of nonunion are early weight bearing and a too short plate. The causes of refracture are screw fixation and empty hole just distal to stem tip. The other caused by the roles of stress riser in proximal screw of blade plate in management of supracondylar fracture.
CONCLUSION
We recommend the use of cerclage band system or fixed in a more proximal site in long plate and bone graft. In unstable prosthesis, we had taken a best results after revised with distal fluted stem, in which we don't need further distal stability like a additional cerclage or locking screw and additional bone graft.
