Impact of abrupt versus gradual correction of mitral and tricuspid regurgitation: a modelling study.

Aims: Correction of mitral and/or tricuspid regurgitation (MR, TR) frequently leads to poor outcomes in the days following intervention. We sought to understand how abrupt correction of MR and TR affects ventricular load and to investigate if gradual correction is beneficial.

Methods And Results: MR and TR were simulated using the CircAdapt cardiovascular system model with effective regurgitant orifice (ERO) areas of 0.

Efficacy of 3-D-imaging in minimally-invasive screw fixation of proximal phalanx fractures: A cadaveric study.

The current study evaluated whether 3-D fluoroscopic imaging is capable of adequate visualisation, reduction and effective guidance of implant placement during a minimally-invasive screw-fixation (MISF) procedure in the treatment of proximal phalanx fractures. A comparison with conventional intraoperative 2-D imaging was performed in a cadaveric model. Conventional 2-D and 3-D imaging series were performed following the creation of proximal phalanx fractures, reduction and fixation, pre- and post-operatively.

Results of total aponeurectomy for Dupuytren's contracture in 61 patients: a retrospective clinical study.

Introduction: Many surgical techniques have been advocated to treat Dupuytren's contracture. Partial fasciectomy is often performed to treat the whole spectrum of Dupuytren's disease.

Method: We have reviewed the effectiveness of total aponeurectomy performed on 61 patients [10 women and 51 men (male:female ratio 5.

Arthrodesis of the distal interphalangeal joint: description of a new technique and clinical follow-up at 2 years.

Introduction: Arthrodesis of the distal interphalangeal joint (DIPJ) is an accepted operative procedure to treat osteoarthritis, instability and joint deformity. There is a wide spectrum of recommended operative techniques including cerclage wires, headless screws, bio-resorbable pins and lag screws. Lag screw fixation remains one of the most accepted methods of fixation; however, problems can occur in particular subsidence of the screw head leading to loss of compression and prominence of the screw head in the finger tip necessitating removal.

[Self-active physical thrombosis prophylaxis in the patients' bed with the Phlebostep: acceptance and measurement of venous blood flow in immobilized patients].

Background: Despite the broad use of low molecular weight heparin, deep vein thrombosis is still a relevant risk for immobilized patients in orthopedic surgery. Patients can reduce this risk by active training exercises with a muscle pump. The aim of this study was to test the acceptance and effect of a self-developed training device to accelerate venous return as well as a technical optimization.
