A comparison among preoperative pedicle screw placement plans, obtained from computed tomography (CT) images manually by two spine surgeons and automatically a computer-assisted method.To analyze compare the manual approach to planning in terms of inter- intraobserver variability.Several methods for have been proposed; however, systematic variability analysis against has not performed yet.For 256 screws, plans were determined experienced surgeons, each independently performing sets...

Background and purpose — The accuracy of conventional navigation systems depends on precise registration bony landmarks. We investigated the clinical use electromagnetic (EMN), with a unique device for determination anterior pelvic plane.Patients methods randomly allocated patients scheduled total hip arthroplasty into 2 groups 42 each. In study group, cups were placed at predetermined target angles (inclination: 42.5°; anteversion: 15°) support EMN. control freehand aiming same angles....

PURPOSE: This study aimed to provide a reliable and valid translation of the Scoliosis Research Society-22 (SRS-22r) questionnaire, compare it with EQ-5D-5 L analyse health-related quality life (HRQoL) patients idiopathic scoliosis (IS) in Slovenia order potentially improve their rehabilitation processes. METHODS: A matched-case-control was performed assess internal consistency reliability, test-retest concurrent validity, discriminative validity. The questionnaire returned by 25 adolescent...

PURPOSE OF THE STUDYInterspinous dynamic stabilisation devices (IDSDs) are used for and indirect decompression of the spinal motion segment in minimally invasive treatment degenerative conditions lumbar spine.Good methodological quality studies on biomechanical effects IDSDs lacking scientific literature.The purpose this study was to evaluate effect IDSD implantation a segment. MATERIAL AND METHODSWe conducted parallel group randomised trial (RT) twelve patients, comparing radiological...

Case: A 68-year-old woman was scheduled to undergo elective correction of coronal spinal malalignment after a previous lumbar instrumented fusion. In the final stages operation, patient became hemodynamically unstable. Her systemic condition worsened subsequently, leading cardiac arrest followed by unsuccessful resuscitation. An autopsy revealed massive fat embolism in lungs. Conclusions: The diagnosis syndrome (FES) is clinical, and treatment supportive, with no clinical or investigative...

The presence of broken surgical blades or other surgically uncontrolled sharp and pointed objects in the disc space is a rare but potentially severe complication posterior lumbar spine procedures. Herein, we report case 59-year-old female patient with history decompression interspinous process device implantation who underwent an instrumented revision lumbosacral junction. During L5–S1 discectomy, scalpel blade broke, fragment could not be retrieved through approach. With regard to vascular...

Spinal deformity correction with vertebral fixation is nowadays the preferred surgical treatment, where pedicle screws are inserted through pedicles into corresponding bodies and afterwards connected rods. In clinical practice, straight-forward anatomical insertion technique currently being used for screw placement surgery. However, it difficult to quantitatively compare both techniques determine which more adequate each planned before surgery (i.e. preoperatively). this paper, we therefore...

The study aimed to assess long-term radiological outcomes in patients from our institution who were primarily treated for adolescent idiopathic scoliosis with surgical correction using Harrington rod (HR) instrumentation, and afterward watchful waiting of residual spinal deformity after HR removal, whereby no patient consented correction. A single-institution case series 12 was retrospectively evaluated. Preoperative most recent post-instrumentation removal radiographic measurements...

Background: Vertebral fixation by pedicle screw placement is the most frequently applied technique in spinal surgery. In this retrospective study we present a comparison of manual and computer-assisted preoperative planning three-dimensional (3D) computed tomography (CT) images deformities thoracic spine.Methods: Manual size trajectory was performed two orthopedic surgeons using dedicated software for surgical procedures, while automated image processing analysis techniques through...

The reported incidence of spondylolysis in athletes varies between 15% and 47%, considerably more than 6% the general population, with most common types related sport activities being gymnastics, weight lifting, soccer, swimming, cricket tennis. (Reitman, Stanitski). repeated tension stress microtrauma on ventro-caudal part inferior articular facet during lumbar hyperextension trunk twisting movements, together anatomical predispositions can result complete symptomatic fracture defect,...

Da bi dosegli zatrditev med gibljivo ledveno hrbtenico in negibljivo križnico, so se ob razvoju instrumentacijskih sistemov za notranje fiksiranje prsno-ledvene hrbtenice razvijale kirurške tehnike, ki omogočajo podaljšati take sisteme na kostne elemente medenice. Izraz sakroiliakalno (SI) zajema vse instrumentacijske tehnike notranjo učvrstitev ledveno-križničnega predela črevnico. Preprečevanje psevdoartroze fuzije prehoda, nastane meji dvema različnima strukturama (gibljivo statičnim...
