Feb 15, 2024 · Pain usually ranges from mild to moderate and may radiate to the thigh. Doctors call post-hip replacement surgery pain in the thigh femoral stem pain.

Femoral stem cementation is a safe and viable alternative to cementless femoral stems and confers superior longevity among certain populations with diminished bone quality.

Over the past five decades, the femoral stem design of THA implants has changed in response to identified needs such as improved longevity, improved materials, and ease of use, and now there exist many viable options for an orthopaedic surgeon to choose .

2 days ago · There are two main philosophies of cemented femoral stem fixation (Figure 19.2): taper-slip/force-closed fixation and composite beam/shape-closed fixation. 13, 15 The taper-slip concept uses a dual- or triple-tapered stem with a smooth or highly polished surface finish allowing the stem to wedge into the cement mantle over the course of the ...

2 days ago · Proximally coated tapered wedge femoral stems have a long track record of durable performance. 1, 6, 7, 10 Combined with a reduced lateral shoulder and impaction broaching, these features have made tapered wedge stems a natural solution to femoral preparation challenges in DAA THA. However, some authors have found increased rates of early ...

Feb 9, 2024 · Currently, cemented femoral stems are broadly classified into two categories: ‘composite-beam’ or ‘shaped-closed’ design and ‘load-tapering’ or ‘force-closed’ design. The composite beam is designed to achieve a strong bond …

The aim of this article is to summarize the state of the art in cementing femoral stems in primary hip arthroplasty. The ultimate goal is to achieve reliable and stable fixation with a low failure rate. Bone cement serves as the foundation of the stem fixation in the femoral canal.

Nov 19, 2021 · Introduction: A comprehensive comparison of the performance of different femoral stem geometries in total hip arthroplasty (THA) is yet to be described. The primary aim of this study was to evaluate objective and subjective outcome measures in primary THA with different femoral implant styles.

2 days ago · The aim is to maintain an intact muscle-osseous sleeve, which is composed mainly of the gluteus medius, greater trochanter, vastus lateralis, and femoral diaphysis fragment. 12 The length of the osteotomy should be measured preoperatively so that the femoral stem can be easily removed and adequate fixation can be provided.

May 18, 2022 · Anatomic stems are designed to match femoral endosteal geometry, specifically the posterior kink in the femoral metaphysis created by anteversion of the femoral neck relative to the femoral shaft and the sagittal anterior bow of the femoral diaphysis.
