Original Paper



Allograft hip composite prosthesis (APC) is a type of reconstruction after resection of the proximal femur. This study aimed to assess long-term outcomes after an APC reconstruction.

Materials and methods

Forty-six patients were retrospectively included (14 revision total hip replacements, 30 primary malignant bone tumors, two metastasis).


The mean length of femoral bone resection was 16.4 cm (7 to 27). With a mean follow-up of 14.7 years (6.3 to 32.6), Postel-Merle d’Aubigné score was 15.7 (8 to 21), Musculoskeletal Tumor Society score at 23.1 or 77% (15 to 29), and abductor strength at 3.4 (2 to 5). Allograft resorption was minor for 20 patients (44.4%), moderate for 13 patients (28.9%), and severe for 12 patients (26.7%). Host-allograft shaft bone fusion was achieved in 37 cases (84.1%). Trochanteric fracture occurred in 26 cases (59.1%). Length of femoral resection, allograft bone resorption, and trochanteric fracture did not have an effect on functional outcomes. At ten years follow-up, overall revision-free and femoral stem survivals were 54.1 ± 0.8% and 81.4 ± 0.6% respectively. No parameter evaluated influenced the survivorship.


APC is a reliable reconstruction adapted for huge proximal femoral bone resections. Trochanteric fracture and allograft bone resorption do not seem to influence functional results.
