Role of Additional Inferomedial Supporting Screws in Osteoporotic 3-Part Proximal Humerus Fracture: Finite Element Analysis

open access: yesGeriatric Orthopaedic Surgery & Rehabilitation, 2020
Introduction: Importance of inferomedial supporting screws in preventing varus collapse has been investigated for the proximal humerus fracture. However, few studies reported the results of osteoporotic complex fracture.

The stability of bone screws in the os sacrum [PDF]

open access: yesEuropean Spine Journal, 1998
A variety of points of insertion and implantation techniques are recommended for inserting screws into the os sacrum. On the basis of 16 complete human sacrum specimens the following axial pull-out tests were performed: 1. Insertion of convergent measuring screws, 6.0 mm and 7.0 mm in outside diameter respectively, into the body of vertebra S1 using a ...

Biomechanical comparison of different fixation methods in tibiotalocalcaneal arthrodesis: a cadaver study

open access: yesJournal of Orthopaedic Surgery and Research, 2023
Background Various fixation methods are available for tibiotalocalcaneal arthrodesis: nail, plate, or screws. An intramedullary bone stabilization system within a balloon catheter has not previously been used in tibiotalocalcaneal arthrodesis. The aim of

Osseointegration of Titanium Implants in Onlay of Cerament™, a New Ceramic Bone Substitute

open access: yesJournal of Functional Biomaterials, 2016
The purpose was to investigate whether a new biphasic and injectable ceramic bone substitute Cerament™ that rapidly remodels to bone, may contribute to the retention of titanium implant screws during the healing period, and to analyze the pattern of bone

A circumferentially flanged tibial tray minimizes bone-tray shear micromotion [PDF]

open access: yes, 2005
Aseptic loosening of the tibial component is the major complication of total knee arthroplasty. There is an association between early excessive shear micromotion between the bone and the tray of the tibial component and late aseptic loosening.

Medium to long-term outcome of thoracoscapular arthrodesis with screw fixation for facioscapulohumeral muscular dystrophy [PDF]

open access: yes, 2013
Background: Shoulder girdle muscle weakness is the most constant feature of facioscapulohumeral muscular dystrophy and leads to scapular winging. Mechanical fixation of the scapula to the thoracic wall provides a stable fulcrum on which the deltoid ...
