Abstract :
A 63-year-old woman (height 1.70 m, weight 92 kg, BMI 31)
with developmental dysplasia of both hips underwent bilateral
hybrid total hip replacement (THR) using the cemented Exeter
V40 stem (offset 44 mm, size 3) and uncemented Trident PSL
(Stryker) with alumina-on-alumina ceramic bearing (Biolox
Forte; Ceramtec, Plochingen, Baden-Württemberg, Ger-
many) at our hospital in 2004. A ceramic femoral head with
a diameter of 36 mm and offset of +5 mm was used. Short-
term functional outcome was excellent. 5 years and 3 months
later, the patient tripped on a flat floor and fell down, and was
unable to move her left leg due to severe pain. Plain radio-
graphs revealed a neck fracture in the Exeter stem. She under-
went revision surgery, during which both the remnant of the
Exeter stem and the uncemented acetabular component were
found to be well fixed.
