Mont and Maar classified fractures of a femur that also treated with a total hip prosthesis. The type of fracture can help determine the optimum management strategy. The authors are from Good Samaritan Hospital in Baltimore.
Type
Description
1
intertrochanteric
2
in proximal femur (subtrochanteric or diaphysis, spanning the stem of the prosthesis)
3
spanning the distal tip of the prosthesis
4
distal to the distal tip of the prosthesis
5
comminuted
6
supracondylar (distal femur)
Type
Management Suggestion
1
nonoperative (traction and casting)
2
cerclage fixation and bone-graft, OR revision to a cemented long-stem prosthesis with cerclage fixation and bone graft
3
cerclage fixation and bone-graft, OR revision to a cemented long-stem prosthesis with cerclage fixation and bone graft
4
long-stem revision and simple traction
5
long-stem revision with supplementary fixation and bone-graft
