Abstract

INTRODUCTION: Cement pressurisation is important for the insertion of both the acetabular and femoral components during Total Hip Arthroplasty (THA). Secondary to pressurization the rare phenomenon of unilateral cement incursion into the nutrient foramen has previously been reported. No bilateral case has been reported to date. This has implications both for misdiagnosis of periprosthetic fractures and for medico-legal consequences due to a presumed adverse intra-operative event.

CASE REPORT: We present a case report of a 59 year old, caucasian female who underwent staged bilateral cemented Stanmore THA. The post-operative radiographs demonstrate evidence of bilateral nutrient foramen penetration intra-operatively by standard viscosity cement. The patient suffered no adverse consequences.

CONCLUSIONS: In summary, cement extravasation into the nutrient foramen is an important differential to be considered in presence of posterior-medial cement in the diaphysis of femur following THA. This requires no further intervention and has no effect on the outcome.
