ABSTRACT Short stem hip implants are becoming increasingly popular since they preserve bone stock and presumably reduce stress‐shielding. However, concerns remain whether suitable for a wide range of patients with varying anatomy. The aim this study was to investigate how femoral anatomy influences stress‐shielding induced by short calcar‐guided across set 90 CT‐based femur models. A computational tool developed that automatically selected the optimal size position stem. Finite element...
This study aimed to determine the contribution of each muscle lower limb walking using positron emission tomography (PET) with [F]-fluorodeoxyglucose (FDG). Furthermore, we compared our results obtained volumetric analysis entire muscles those a more traditional approach considering uptake in only one slice segment.Ten healthy subjects walked on treadmill at self-selected comfortable speed for 90 min, 60 min before and 30 after intravenous injection 50-MBq FDG. A PET/computerized scan was...
We report on a structured light-scanning system, the OGX|4DSCANNER, capable of capturing surface human body with 2 mm spatial resolution at 60 Hz frame-rate. The performance modeling lower dynamics is evaluated by comparing system current gold standard, i.e., VICON system. relies application reflective markers person's and tracking their positions in three-dimensional space using multiple cameras [optical motion capture (OMC)]. For purpose validation 4DSCANNER, set "virtual" was extracted...
Introduction Untreated unilateral developmental dysplasia of the hip (DDH) results in asymmetry gait and strength may lead to early osteoarthritis, which is commonly treated with a total arthroplasty (THA). There limited knowledge about obtained symmetry after THA. The objectives this cross-sectional study were to: a) identify asymmetries between operated non-operated side kinematics, kinetics strength, b) analyze if increased walking speed changed level patients c) compare these those...
Accurate predictions of functional outcome after limb salvage surgery (LSS) in the lower are important for several reasons, including informing patient preoperatively and, some cases, deciding between amputation and LSS. This study aimed to elucidate correlation surgeon-predicted patient-reported LSS Netherlands. Twenty-three patients (between six months ten years surgery) five independent orthopedic oncologists completed Toronto Extremity Salvage Score (TESS) RAND-36 physical functioning...
In adult patients with developmental hip dysplasia, a surgical procedure (triple innominate osteotomy) of the pelvic bone can be performed to rotate acetabulum in frontal plane, establishing better acetabular coverage. Although common clinical scores demonstrate significant improvements after surgery, they provide only overall information about function. The purpose this study was quantify long-term outcome triple osteotomy more detail using gait analyses and muscle strength measurements. We...
Aims Hip arthroplasty does not always restore normal anatomy. This is due to inaccurate surgery or lack of stem sizes. We evaluated the aptitude four total hip systems an anatomical and medialized rotation centre. Methods Using 3D templating software in 49 CT scans non-deformed femora, we virtually implanted: 1) small uncemented calcar-guided stems with two offset options (Optimys, Mathys), 2) straight (Summit, DePuy Synthes), 3) cemented undersized (Exeter philosophy) three (CPT,...
Purpose This study aimed to elucidate whether muscle activity (in terms of glucose uptake) between the legs can be considered symmetrical during walking. Furthermore, we determine [18F]-fluorodeoxyglucose was distributed heterogeneously throughout each muscle, and if so, areas high uptake would clustered. Methods Ten healthy participants walked on a treadmill at self-selected comfortable walking speed for total 90 minutes, 60 minutes before 30 after intravenous injection 50 MBq...
