Hm. Staal et al., Stem displacement during reduction of a dislocated cemented total hip arthroplasty with a polished tapered stem, J ARTHROPLA, 15(7), 2000, pp. 944-946
Displacement of the polished stem of a total hip arthroplasty from its ceme
nted mantle occurred as a complication of an attempted closed reduction aft
er luxation. No cement fractures were seen during subsequent reoperation. T
he complication can be avoided if cement is placed over the shoulder of the
prosthesis.
