Early loosening of a press-fit cup with ceramic-on-ceramic articulation: our early results.

Introduction: In this study, we present the short-term results of the Selexys TH+ cup with the Ceramys inlay which is a press-fit cup with a ceramic-on-ceramic articulation. (Mathys, Bettlach, Switzerland). We compared the results with a retrospective-matched control group with a Delta PF cup (Lima, Udine, Italy), which is also a press-fit cup with a ceramic-on-ceramic articulation.

Above- or below-elbow casts for distal third forearm fractures in children? A meta-analysis of the literature.

Introduction: Fractures of the distal third forearm are common fractures in childhood. Most of these fractures can be treated non-operatively by means of closed reduction and immobilization. The purpose of this meta-analysis is to investigate whether above- or below-elbow cast should be considered the first-choice for conservative treatment.

Screw fixation of the syndesmosis: a cadaver model comparing stainless steel and titanium screws and three and four cortical fixation.

We assessed syndesmotic set screw strength and fixation capacity during cyclical testing in a cadaver model simulating protected weight bearing. Sixteen fresh frozen legs with artificial syndesmotic injuries and a syndesmotic set screw made of stainless steel or titanium, inserted through three or four cortices, were axially loaded with 800 N for 225,000 cycles in a materials testing machine. The 225,000 cycles equals the number of paces taken by a person walking in a below knee plaster during 9 weeks.
