Influence of the Screw Positioning on the Stability of Locking Plate for Proximal Tibial Fractures: A Numerical Approach

2020

Tibial fractures are common injuries in people. The proper treatment of these fractures is important in order to recover complete mobility. The aim of this work was to investigate if screw positioning in plates for proximal tibial fractures can affect the stability of the system, and if it can consequently influence the patient healing time. In fact, a more stable construct could allow the reduction of the non-weight-bearing period and consequently speed up the healing process. For that purpose, virtual models of fractured bone/plate assemblies were created, and numerical simulations were performed to evaluate the reaction forces and the maximum value of the contact pressure at the screw/bo…

Cemented and screw-retained implant-supported single-tooth restorations in the molar mandibular region: A retrospective comparison study after an obs…

2015

Objectives: The aim of this study was to evaluate the survival and compare the appearance of different mechanical and biological complications, in screw-retained and cemented-retained single-tooth implant-supported restorations localized in the molar mandibular region, over a period of 1 to 4 years. Material and Methods: A retrospective study was carried out with a total of eighty implant-supported restorations, which were placed in eighty patients for prosthetic rehabilitation of a mandibular molar. Forty patients were rehabilitated with a cemented-retained restoration and the other forty with a screw-retained restoration. The presence of the following complications was recorded for both t…

Quasi-Fractional Models of Human Tendons Hereditariness

2018

In this study, the authors, after collecting a series of experimental evidences following a creep and relaxation tendon campaign, propose a non-linear model of the viscoelastic behavior of the tendons. The ligaments investigated are the patellars and the hamstrings. The analytical model proposed by the authors aims to explain the non-linear hereditary behavior of these tissues and proposes an approach with which to develop a hereditary fractional-order non-linear model.

Impingement of the Sciatic Nerve due to a Protruding Acetabular Cage Rim

2020

Abstract Sciatic nerve damage is a well-known complication that occurs in 1.5% of patients after primary total hip arthroplasty and in 8% after revision total hip arthroplasty. Yet when considering re-revision arthroplasty and acetabular cage implantation, incidence and management remain unclear. This case report describes a young female patient with sciatic nerve impingement after acetabular cage implantation. Her primary complaint was shooting sciatic left leg pain, worsening on ambulation and when seated. A complete workup was negative for spinal impingement or infection, and axonal nerve damage was confirmed through nerve conduction studies. The intraoperative findings showed that it wa…

Anti-TNF-Antikörper zur Therapie von entzündlichen Darmstenosen bei Morbus Crohn

2003

Stenoses are a frequent complication in patients with Crohn's disease and represent a major diagnostic and therapeutic challenge. The proper assessment of the nature of a stenosis as inflammatory or fibrotic is critical for appropriate treatment, since symptomatic fibrotic stenoses require surgical resection. Standard diagnostic procedures to assess the nature of a stenosis include endoscopy, conventional contrast radiography and magnetic resonance tomography. Recent data suggest, that the positron-emission-tomography possesses a high sensitivity and specificity to confirm inflammatory activity in the bowel. The recombinant monoclonal anti-TNF-antibody Infliximab (Remicade) has been approve…

Primäre Ellenbogenprothese bei distalen Humerustrümmerfrakturen

2004

The use of hip- and shoulder arthroplasty in elderly patients for grossly displaced intraarticular fractures is being more and more accepted. Total elbow replacement (TER) has not been considered as an option for the treatment of extensively comminuted fractures of the distal humerus because surgeons feel the outcome is not predictable after TER generally. On the basis of a Medline literature research of this issue and the documented results based on the improvement of the designs of the implants, operative technique and the selection of patients, TER has a definite role in the treatment of some fractures of the distal humerus. We retrospectively reviewed forty-nine acute distal humeral fra…

Multiple osteoartikuläre Komplikationen (dialyse-assoziierte Spondarthropathie) und Karpaltunnelsyndrom bei chronischer Hämodialyse

2008

Abstract During a nine-year treatment by haemodialysis for renal failure a now 57-year-old woman developed multiple complications of the skeletal system. Acute calcific periarthritis of the right shoulder became manifest one year after the start of the haemodialysis, followed the next years by progressive arthropathy with subchondral amyloid cysts of both shoulders, effusions in the knee-joint and destructive spondylarthropathy of the middle vertebrae. Carpal-tunnel syndrome also occurred, caused by a beta 2-microglobulin amyloidosis (beta 2-microglobulin concentration in serum 42.6 ng/l) and an aluminium osteopathy. These multiple complications, observed here in one patient, are each of th…

All that glitters is not gold: A spinal epidural empyema following epidural steroid injection

2020

Background: Therapeutic epidural spinal injections (ESIs) of steroids are one of the most common nonsurgical management modalities employed for alleviating pain due to chronic persistent lumbar spinal disease. However, it is well documented that they have significant risks and complications without any long-term efficacy. ESI may result in epidural empyema which may be difficult to diagnose with delays resulting in significant permanent neurological sequelae. Case Description: A 45-year-old female presented with a lumbar spinal epidural empyema after receiving ESI for low back and right leg pain due to a lumbar disc herniation. Laboratory studies showed elevations of multiple inflammatory …

Intra-Articular Injection of Botulinum Toxin for the Treatment of Knee Osteoarthritis: A Systematic Review of Randomized Controlled Trials

2023

The purpose of the present paper was to review the available evidence on intra-articular botulinum toxin (BTX) injection in the treatment of knee osteoarthritis and to compare it to other conservative treatment options. A systematic review of the literature was performed on the PubMed, Scopus, Cochrane Library, Web of Science, Pedro and Research Gate databases with the following inclusion criteria: (1) randomized controlled trials (RCTs), (2) written in the English language, and (3) published on indexed journals in the last 20 years (2001–2021) dealing with the use of BTX intra-articular injection for the treatment of knee OA. The risk of bias was assessed using the Cochrane Risk of Bias to…
