[The use of uncemented extensively porous-coated femoral components in the management of Vancouver type B2 periprosthetic femoral fractures].
OBJECTIVE
To assess the outcome of patients with Vancouver type B2 periprosthetic fractures treated with femoral revision using an uncemented extensively porous-coated implant.


METHODS
From October 2002 to May 2007, a retrospective clinical and radiographic assessment of 10 patients with Vancouver type B2 periprosthetic fractures treated with femoral revision was evaluated, among which 4 was cement fixation, 6 was non-cement fixation in the index procedure.


RESULTS
The mean follow-up for these patients was 44 months (range, 12 to 67 months). The mean Harris hip score was 87.6 points. All 10 reconstructions showed solid fracture union and a stable prosthesis, 8 was bone ingrowth, 2 was fibrous ingrowth. Complications in 4 patients included thigh pain in 1, stress shield in 3.


CONCLUSIONS
Vancouver type B2 periprosthetic fractures treated with uncemented extensively porous-coated femoral stems incorporate distally allowing stable fixation.
