“…We have shown that the Thackray polyethylene plug (Fig. 1) has a failure rate of at least 25%, and this has been confirmed by others (Bakker et al 1988;Northmore-Ball, Narang and Vergroesen 1991;Thomsen et al 1992). Cement leakage and migration of the plug were observed frequently and osteolysis of the bone around the plug was seen in 5% of firmly fixed prostheses by five The Thackray polyethylene cement plug.…”

We have investigated the use of a conically-shaped cement plug made of Polyactive (PA), a biodegradable copolymer. The flexibility and hydrogel properties were thought to facilitate occlusion of the femoral canal even when it was oval or irregular in shape. The function of the plug was first compared with that of the Thackray polyethylene model in 16 artificial plastic femora.The maximum intramedullary pressure achieved during cementing was ten times higher with the biodegradable model. Migration or leakage of cement did not occur when the diameter of the femoral canal was equal to or smaller than the diameter of the plug. We also showed that the biodegradable properties of this implant were such that it did not require removal during revision.The new plug was tested in a pilot clinical trial. At two years only two out of 21 patients had evidence of migration or leakage of cement, probably due to a mismatch in the size of plug and femoral canal. There were no local changes in the femur.

We reviewed a series of consecutive total hip replacements with cemented femoral components. Modern cementing techniques were followed in all cases, but two different medullary plugs were used-one was polyethylene and the other bioabsorbable gelatin. Cement mantle quality and plug migration were assessed by three different observers (X, Y, and Z); their findings did not agree. This was particularly evident when the cement mantles were assessed. There was a better cement mantle grading and less distal migration with polyethylene plugs, although there was no significant statistical difference between the two groups.Résumé Nous avons étudié une série de prothèses totales de hanche consécutives avec un composant fémoral cimenté. Les techniques modernes de cimentage ont été utilisées dans tous les cas avec une obturation médullaire par un bouchon de polyéthylène ou par un bouchon de gélatine bio-absorbable. La qualité du manchon cimente et la migration du bouchon ont été évaluées par trois observateurs différents. Pour l'évaluation du manchon de ciment la concordance inter observateur a été mauvaise. Dans les cas avec obturateur en polyéthylène un manchon de ciment de meilleure qualité et une moindre migration distale du bouchon ont été notés, sans signification statistique cependant.

“…Various experimental studies have been published on the efficacy of intramedullary plugs (Oh et al 1978, Lee and Ling 1981, Beim et al 1989, Maltry et al 1995, Prendergast et al 1999, Yee et al 1999, Heisel et al 2003. Pressure measurements, testing of shear stresses, and examination of the effects of back bleeding have been done; a few comparative studies have analyzed the clinical outcome and performance of cement restrictors (Thomsen et al 1992, Bulstra et al 1996, Visser et al 2002.…”

“…■ For adequate cement interdigitation, the use of a distal intramedullary cement restrictor (plug) is essential in order to obtain high cement pressures (Markolf and Amstutz 1976, Bannister and Miles 1988, Bean et al 1988. Plug performance should be consistent and reliable, but comparative clinical studies have shown high variability between different designs and materials (Thomsen et al 1992, Bulstra et al 1996, Visser et al 2002. Even wellcontrolled biomechanical tests have confirmed that there is a high variability in plug performance with regard to stability and occlusion of the intramedullary cavity (Prendergast et al 1999, Danter et al 2000, Heisel et al 2003.…”
