Evaluation results of surgical treatment of periprosthetic femoral fractures of THA in years 2004-2010

Martin KorbelOrtopedická klinika FN Hradec Králové

Page 2: Periprosthetic fractures

Incidence 0,4 – 6 %

increase in revision surgeries obese patiens (BMI over 35) elderly patients with fragile bones in cementless total hip arthoplasties

Page 3: Periprosthetic fractures

Vancouver classification

- location of the fracture- fixation of the stem- quality of the remaining bone stock

Page 4: Periprosthetic fractures

Vancouver A

fractures involve the greater or lesser trochanter

stable conservative treatment (protected weight bearing)

unstable trochanteric cerclage

Page 5: Periprosthetic fractures

Vancouver B

around or just distal to stem surgical treatment

B1 – the stem remains well fixed

open reduction and internal fixation

B2 – the stem is loose long stem revision, cerclage

B3 – the stem is loose and the proximal femur is

deficientlong stem revision, cerclage

Page 6: Periprosthetic fractures

Vancouver C

below the stem with no stem loosening

open reduction and internal fixation leaving the stem

Conclusion

large number of patients with diseases of the nervous or musculoskeletal system

generally poor results with a large number of complications in the group of Vancouver B2 fractures

Vancouver B2 fractures treated with the implantation of the revision stems and cerclage
