OBJECTIVE The traditional freehand technique for external ventricular drain (EVD) placement is most frequently used, but remains the primary risk factor inaccurate placement. As this procedure could benefit from image guidance, authors set forth to demonstrate impact of augmented-reality (AR) assistance on accuracy and learning curve EVD compared with technique. METHODS Sixteen medical students performed a total 128 placements custom-made phantom head, both before after receiving...
Before starting surgery for the resection of an intracranial tumor, its outlines are typically marked on skin patient. This allows planning optimal incision, craniotomy, and angle approach. Conventionally, surgeon determines tumor borders using neuronavigation with a tracked pointer. However, interpretation errors can lead to important deviations, especially deep-seated tumors, potentially resulting in suboptimal approach incomplete exposure. Augmented reality (AR) displaying critical...
We present the results of a 5 year prospective follow-up study on functional outcome after total replacement trapeziometacarpal joint with Ivory prosthesis (Memometal, Stryker Corporate, Kalamazoo, Michigan, USA) in 22 patients. The female to male ratio was 21:1 and mean age 66 (range 54-78) years. period 67 60-77) months operation. Patient satisfaction high. mobility operated thumb restored range motion comparable contralateral thumb. Key pinch grip strength improved by 13% 31%,...
BACKGROUND AND OBJECTIVES: External ventricular drain (EVD) placement is often performed freehand, a technique subpar to accurate yet impractical image-guided methods, yielding optimal in only 70%. The aim of this study was address shortcomings EVD and image guidance technologies by implementing high-accuracy augmented reality (AR) guidance. METHODS: We conducted prospective clinical pilot assess feasibility, safety, performance using standalone AR headset equipped with inside-out infrared...
We carried out percutaneous, arthroscopically- and fluoroscopically-assisted osteosynthesis of fractures the tibial plateau in 52 patients, whom 38 were assessed using HSS knee score standing radiographs. reviewed 31 AO type-B seven type-C after a mean follow-up five years (1 to 14). Fixation was achieved percutaneous screws and/or an external frame; 33 associated intra-articular injuries, diagnosed 21 treated arthroscopically. Subjectively, 94.7% patients satisfied. According 78.9% results...
Spinal pain syndromes have a severe impact on the patient's sex life, contributing to decrease in sexual function and satisfaction. Despite importance of health mental physical wellbeing, is rarely discussed during consultations. The aim this study explore what extent influencing factors can alter discussion about More specifically, we will evaluate influence healthcare profession, patient surgical approach that proposed. An online survey was sent neurosurgeons, physicians orthopedists...
Background We compared anesthesia time, complications, fracture healing, as well shoulder and elbow function after retrograde antegrade nailing of humeral shaft fractures or impending fractures. Methods Thirty Marchetti-Vicenzi nails (MVN) 22 locked AO unreamed (AO-UHN) were inserted in 52 patients. Forty-three followed up until three required reoperation for nonunion (two MVN, one AO-UHN). Nineteen MVN 17 AO-UHN patients evaluated according to Constant's score HSS an average 2 years...
Background and purpose Two contradictory cementing techniques (using an undersized stem versus a canal-filling stem) can both lead to excellent survival rates, phenomenon known as the “French paradox”. Furthermore, previous studies have indicated that type of bone supporting cement mantle may affect implant survival. To further evaluate mechanical consequences variations in technique, we studied effect size on performance cemented total hip arthroplasty, using finite element analysis.Methods...
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...

Background: The cement mantle within a hip resurfacing head is important for implant survival. Too much leads to thermal bone necrosis, whereas not enough might cause mechanical failure and particle-induced osteolysis. We evaluated the impact of different cementing techniques on quality in resurfacing. Methods: Sixty bovine condyles were prepared fit size-46 ReCap (Biomet) divided into five groups twelve specimens each. In two groups, polymeric replica was filled halfway with low-viscosity...
Abstract Femoral fractures within resurfacing implants have been associated with bone necrosis, possibly resulting from heat generated by cement polymerization. The amount of depends on mantle volume and type cement. Using finite element analysis, the effect thermal necrosis was analyzed. Based CT‐data earlier implantations, two different models were created: a thick model, representing low‐viscosity “cement filling” technique, thin high viscosity packing” technique. Six types polymerization...
Background: Specific treatment of the volar marginal rim fragment distal radius fractures avoids occurance radiocarpal dislocation. Although several fixation systems are available to capture this fragment, adequately maintaining internal is difficult. We present our experience first 10 cases using 2.4 mm variable angle LCP plate (Depuy Synthes®, West Chester, US), a low-profile rim-contouring designed for positioning and stable buttressing fragment. Methods: Follow-up patient satisfaction,...
Using a modern cementing technique, we implanted 22 stereolithographic polymeric replicas of the Charnley-Kerboul stem in 11 pairs human cadaver femora. On one side, were cemented line-to-line with largest broach. other, one-size undersized used (radial difference, 0.89 mm sd 0.13).CT analysis showed that stems without distal centralisers at least as well aligned and centered centraliser, but surrounded by less cement presented more areas thin (< 2 mm) or deficient 1 cement. These located...
