Bilateral Femoral Nutrient Foraminal Cement Penetration during Total Hip Arthroplasty.

Journal of orthopaedic case reports

Coomber R, Bhumbra RS, Marston R.
PMID: 27298876
J Orthop Case Rep. 2012 Oct-Dec;2(4):4-6.

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...

Comparison of computed tomography dose index in polymethyl methacrylate and nylon dosimetry phantoms.

Journal of medical physics

Sookpeng S, Cheebsumon P, Pengpan T, Martin C.
PMID: 27051170
J Med Phys. 2016 Jan-Mar;41(1):45-51. doi: 10.4103/0971-6203.177287.

The use of computed tomography (CT) scanning has been growing steadily. Therefore, CT dose measurement is becoming increasingly important for patient protection and optimization. A phantom is an important tool for dose measurement. This paper focuses on the evaluation...
