Comparison of Specific Femoral Short Stems and Conventional-Length Stems in Primary Cementless Total Hip Arthroplasty.
There are several reported disadvantages with conventional-length femoral stems in cementless total hip arthroplasty (THA). Therefore, various efforts have been made to develop a specific femoral short stem to improve physiologic bone remodeling at the femoral aspect of a cementless THA. However, there are potential disadvantages with specific femoral short stems, such as malalignment, inadvert...
متن کاملFracture of cementless femoral stems at the mid-stem junction in modular revision hip arthroplasty systems.
BACKGROUND Mechanical failure of femoral stems at the modular junction of revision hip arthroplasty systems has been reported only infrequently. In the current study, the cause of six stem fractures, which occurred in vivo, was analyzed with use of clinical data and failure analysis. METHODS Six patients with a fracture at the mid-stem junction of a modular revision hip implant were identifie...
متن کاملThe Effect of Physiological Load Configuration on Interface Micromotion in Cementless Femoral Stems
The most commonly reported failure modes of cementless hip stems are loosening and thigh pain; both are attributed to the relative motion at the bone-implant interface due to failure to achieve sufficient primary fixation. Accurate predictions of hip stems’ stability are therefore crucial to the pre-clinical analyses of hip arthroplasty. This study uses finite element technique to analyse the e...
متن کامل[Conservative femoral implants. Short stems].
Uncemented hip replacement matches the best results of classic cemented replacements. With the aim of preserving bone and soft tissue, implants with shorter stems and proximal metaphyseal support have been developed. Likewise, the lack of distal load should avoid cortical diaphyseal remodelling phenomena and the thigh pain of some cylindrical and wedge implants. The resurfacing implant, very po...
متن کاملSpanning trees whose stems have at most k leaves
Let T be a tree. A vertex of T with degree one is called a leaf, and the set of leaves of T is denoted by Leaf(T ). The subtree T − Leaf(T ) of T is called the stem of T and denoted by Stem(T ). A spanning tree with specified stem was first considered in [3]. A tree whose maximum degree at most k is called a k-tree. Similarly, a stem whose maximum degree at most k in it is called a k-stem, and ...
