The pattern of the fracture and displacement of the fragments predict the outcome in proximal humeral fractures.

Our aim was to determine the effect of the initial pattern of fracture and the displacement of fragments on the outcome of proximal humeral fractures treated conservatively. We followed 93 consecutive patients prospectively for one year. Final movement and strength were compared with those of the contralateral side.

Interactions of human bone cells with diamond-like carbon polymer hybrid coatings.

Diamond-like carbon (DLC) coatings produced using the plasma-accelerating filtered pulsed arc discharge (FPAD) method display excellent adherence to the substrate and improve its corrosion resistance. This article reports the interactions of human osteoblastic cells with DLC and two DLC polymer hybrid (DLC-p-h) coatings deposited on smooth, matt and rough silicon wafers by the FPAD method. The DLC-p-h materials were DLC-polytetrafluoroethylene hybrid (DLC-PTFE-h) and DLC-polydimethylsiloxane hybrid (DLC-PDMS-h) coatings.

Proximal humerus fracture rotational stability after fixation using a locking plate or a fixed-angle locked nail: the role of implant stiffness.

Background: Fixed-angle locked devices have been developed to improve internal fixation of proximal humerus fractures. Available low-profile precontoured locking plates and intramedullary nails with fixed-angle interlocks are currently favored by most surgeons in this setting. The aim of this study was to assess the relative stability of these two methods of fixation under torsion load.

Using metal-ligand interactions for the synthesis of metallostar polymers.

In this work we report the synthesis and assembly of metallostar polymers using a combination of metal complexation, RAFT and Click chemistry.

Identification of differentially expressed genes in trabecular bone from the iliac crest of osteoarthritic patients.

Objective: Osteoarthritis (OA) is clinically characterized by degeneration of the joints and has been traditionally considered a primary disorder of articular cartilage, with secondary changes in the subchondral bone. The increased bone mass and generalized changes in bone quality observed in osteoarthritic patients suggest that OA may be a primary systemic bone disorder with secondary articular cartilage damage. The iliac crest is a skeletal site distant from the affected joint, with a minimal load-bearing function.
