Abstract
Acetabular loosening is often dangerous because the patient is pain free for several years. The following bone loss may represent the biggest challenge in revision surgery.
Object of this study is to evaluate the use of an iliac stem cup (Link®) associated with impacted bone grafts in acetabular loosening and CDH.
We performed 25 implants in loosening (13 grade 2 and 12 grade 3 of Paprosky): average age was 68 years old in 16 female and 9 male. Mean follow up was 22 months.
We used bone grafts in 17 cases. In 1 case we cemented the Mcminn cup because of poor initial stability with no complication at 18 months.
We noted radiolucency lines < 2 mm. in 1 case and bone resorption in 2 cases. The complications were: malpositioning of the stem (1%), sacroiliac pain (4%), superficial infection (2%) and DVT (1%).
In conclusion, we can affirm that McMinn cup, despite a demanding surgical technique, represents a valid alternative to acetabular revision surgery because of the good initial stability, the respect of loading lines and besides it allows the use of pressurized bone chips.
