In situ synthesis of FeO nanoparticles coated by chito-oligosaccharides: physico-chemical characterizations and cytotoxicity evaluation for biomedical applications.

Nanotechnology 2020 Apr 8;31(17):175602. Epub 2020 Jan 8.

IMP, CNRS UMR 5223, Univ Claude Bernard Lyon 1, Univ Lyon, 15 bd Latarjet, F-69622 Villeurbanne, France.

FeO nanoparticles coated with chito-oligosaccharides (COS) were prepared in situ by a simple co-precipitation method through a mixing of iron ions (Fe and Fe) and COS aqueous solutions followed by precipitation with ammonia. The impact of COS with different degree of polymerization (DP 10, 24 and 45) and degree of N-acetylation (DA) ∼ 24% and 50% (exhibiting high solubility) on the synthesis and physical properties of the coated magnetic nanoparticles was evaluated. Several advantages were found when the magnetic nanoparticles were prepared in the presence of the studied COS, such as: preparation of functionalized magnetic nanoparticles with narrower size distributions and, consequently, higher saturation magnetization (an increase of up to 22%); and an expressive increasing in the concentration of COS-coated magnetic nanoparticles (up to twice) in the cell viability test in comparison with pure FeO nanoparticles.

Bone-mediated anteroinferior glenohumeral instability : Current concepts.

Orthopade 2018 Feb;47(2):129-138

Center for Musculoskeletal Surgery, Charité-Universitätsmedizin Berlin, Augustenburger Platz 1, 13353, Berlin, Germany.

Recurrent anterior shoulder instability is commonly associated with defects of the anterior glenoid rim. Substantial osseous defects significantly diminish the glenohumeral stability and require a bony augmentation, either by a coracoid transfer or free bone grafting procedure. Both reconstructive techniques have been applied for a long time and evaluated biomechanically and clinically. Read More

One step arthroscopically assisted Latarjet and posterior bone-block, for recurrent posterior instability and anterior traumatic dislocation.

Int J Shoulder Surg 2015 Jul-Sep;9(3):94-8

Department of Shoulder Surgery, IRCCS Galeazzi Orthopaedic Institute, Milan, Italy ; Department of Surgery, Upper Limb Unit, OBV, Mendrisio, Switzerland.

This case presents the challenges of the surgical management for a patient with a history of recurrent posterior shoulder instability and subsequently traumatic anterior dislocation. The patient was already on the waiting list for an arthroscopic posterior stabilization with anchors, when a car accident caused an additional anterior shoulder dislocation. This traumatic anterior dislocation created a bone loss with a glenoid fracture and aggravated the preexisting posterior instability. Read More

Arthroscopically assisted Latarjet procedure: A new surgical approach for accurate coracoid graft placement and compression.

Int J Shoulder Surg 2013 Jul;7(3):120-3

Upper Limb Unit, Department of Surgery, OBV, Mendrisio, Switzerland.

The Latarjet procedure is a confirmed method for the treatment of shoulder instability in the presence of bone loss. It is a challenging procedure for which a key point is the correct placement of the coracoid graft onto the glenoid neck. We here present our technique for an athroscopically assisted Latarjet procedure with a new drill guide, permitting an accurate and reproducible positioning of the coracoid graft, with optimal compression of the graft onto the glenoid neck due to the perfect position of the screws: perpendicular to the graft and the glenoid neck and parallel between them.
