“…The thin cement mantle technique was introduced by Postel et al [26], and is widely used in France [9]. Langlais et al [9] introduced the design philosophy of the Charnley-Kerboull and the Ceraver Osteal stems, which includes very thin and sometimes incomplete cement mantles.…”

“…Langlais et al [9] introduced the design philosophy of the Charnley-Kerboull and the Ceraver Osteal stems, which includes very thin and sometimes incomplete cement mantles. They commented that the vigorous insertion of a canal-filling stem into doughy cement would produce a marked pressure increase at the cement-bone interface during stem insertion, and stronger initial mechanical interlocking at the cement-bone interface could be obtained.…”

“…Langlais et al [9] described that French stems using the thin cement mantle technique, provided that their surfaces are polished, function well in the medium and long term, although the cement mantles are extremely thin and may be incomplete. The average surface roughness of the stem used in this study was 0.5 µm to 2.2 µm, suggesting that good results can be expected even if rougher surface stems are used.…”

This paper presents the mid-term results of hybrid total hip arthroplasty for patients with hip dysplasia using a tight fit technique for the femoral component. We followed 113 hips in 99 patients for a mean of 11 years. All final femoral rasps used in this study over-rasped by 0.5 -1.0 mm for stem insertion, resulting in relatively thin cement mantles. Both components of one hip were removed due to infection. The other 5 acetabular components were revised for osteolysis, recurrent dislocation, or dislodgement of the polyethylene liner.No femoral component was revised for aseptic loosening. We conclude that the tight fit technique using a canal-filling stem may produce good long-term results for patient with hip dysplasia.

“…On the other hand, the thin cement mantle technique was introduced by Postel [21]. Langlais et al showed good clinical results with a thin cement mantle technique using Charnley-Kerboull and the Ceraver Osteal cemented femoral components [14]. These stems were intended to fully fill the medullary canal of the femur.…”

A 4-U hybrid total hip arthroplasty (THA) system was specifically designed for patients with developmental dysplasia of the hip (DDH). Straight stem with an appropriate offset and various size variations are advantages. We followed 128 hips in 124 patients, 13 men and 111 women, for a mean of 6.5 years (range, 5.0-7.5 years). Two acetabular and femoral components in two patients had been revised for infection, one acetabular component had been revised for recurrent dislocation, and one femoral component had been revised for periprosthetic femoral fracture. None of the acetabular or femoral components were revised for loosening or were found to be loose at follow-up. The Harris hip score increased from a preoperative average of 42 points to 88 points at the most recent follow-up. Primary THA using the 4-U system had a good mid-term result in patients with DDH. This system could be applied for all patients including those with the narrowest and deformed femurs.

“…However, migration was limited in size and did not progress over 1 year. Stability of the femoral component is said to depend on several factors, including optimal graft packing and mechanical resistance, good stem filling of the neo-canal combined with a thin cement mantle [16] and intrinsic properties of the collared stem. Nevertheless, the influence of synthetic grafting on mechanical resistance of the reconstruction still is unclear.…”
