Interprosthetic femoral fractures treated with locking plate

“…Soenen et al reported one of 14 patients dying within six months of the fracture event [12]. Platzer et al reported one of 23 patients dying from cardiac arrest 15 days postoperatively [13], and Ehlinger et al reported one death out of eight patients four months after operation [19]. This study reports three of 15 patients dying within six months postoperatively, including one patient already full weight bearing.…”

“…This studies' conflicting result of incidence of fracture location suggests limited value predicting interprosthetic fracture location with such a small sample size. Ehlinger et al had eight patients treated with locked plates spanning the femur, with healing in an average of 14 weeks [19]. In contrast, Hou et al treated 13 patients with interprosthetic fracture as if they were isolated periprosthetic fractures [10]: four were treated with total joint revision and nine with locking plate.…”

“…Only 77 of these cases used locking plates, all of whom had varied treatments. Several authors used locking plates spanning the tips of the prostheses for all fracture types [11,19]. Other interprosthetic fractures were managed as if they were isolated periprosthetic fractures [10].…”

Enhancing fixation strength in periprosthetic femur fractures by orthogonal plating—A biomechanical study

“…In case of persisting instability, they proposed the placement of an additional anterior plate. Beside periprosthetic and interprosthetic fracture fixation, the orthogonal plating technique was successfully applied in nonunion treatment . Especially in revision surgery, where bone healing might be decelerated or bone defects bridged with bonegrafts, orthogonal plating can provide a stable mechanical environment…”

“…Beside periprosthetic and interprosthetic fracture fixation, the orthogonal plating technique was successfully applied in nonunion treatment. 9,21,22 Especially in revision surgery, where bone healing might be decelerated or bone defects bridged with bonegrafts, 23 orthogonal plating can provide a stable mechanical environment. 22 This study has several limitations: Due to the in vitro character of the study, the reinforcing effect of bone healing on the construct stability could not be investigated so that these data focus on direct postoperative primary stability.…”
