In the treatment of anterior shoulder instability, there are various conditions in which a sling effect is needed to enhance anterior stability. The traditional Bristow-Latarjet procedure provides a sling effect but destroys or does not purposely protect the coracoacromial (CA) arch, which may result in superior instability. To preserve the CA arch and create a sling to enhance the anterior-inferior side of the shoulder, we introduce an arthroscopic technique to transfer the conjoined tendon-coracoid tip complex (CTCTC) with the intention to keep the CA ligament intact to the utmost...

BACKGROUND: Damage to the cardiac conduction system requiring permanent pacemaker (PPM) implantation is a known adverse outcome of transcatheter aortic valve replacement (TAVR). A permanent-temporary pacemaker (PTPM) is a device that involves an active-fixation lead attached to an external pulse generator taped to the skin. We reviewed the utility of PTPMs as a temporary bridge measure after TAVR in patients with conduction abnormalities that do not meet conventional criteria for PPM placement...

OBJECTIVES: The best fixation method for open tibial fractures has long been a matter of debate, many studies have recommended the use of intramedullary nails over external fixation for treating such fractures, recent studies also showed favorable results for the use of plates in managing open tibial fractures. However, there are very few (if any) reports in the literature comparing the use of minimally invasive plate osteosynthesis to reamed intramedullary nails in the fixation of open tibial fractures...

PURPOSE: To present a new arthroscopic method for treating supination losses. METHODS: Six patients (15-71 y) were eligible for this study. All had a history of trauma to the wrist more than 6 months previously. Five of them had sustained a distal radius fracture: 3 had been treated with a volar plate (1 of them for an extra-articular malunion), 1 with an external fixator and K-wires, and 1 had been treated in a cast. One of these patients underwent a further operation for correcting an intra-articular malunion...

This work deals with the structural analysis of screw clamps for external fixator devices. Screw clamps are widely used in external fixators as a means to connect the half-pins to the fixator body. The analysis is carried out by both numerical and experimental techniques, based on the case study of a clamp produced by Citieffe (Bologna, Italy). As a preliminary activity, the tribological parameters involved in the screw-clamp interaction have been characterized by means of a mixed finite element analysis and experimental procedure...

BACKGROUND: In a progredient rotator cuff tear with tendon retraction, fatty infiltration and atrophy of rotator cuff muscles the humerus cannot be centered and stabilized sufficiently in the glenohumeral joint. This leads to rotator cuff defect arthropathy as an eccentric osteoarthritis with acetabularization and wear of the acromion, as well as of the glenoid. INDICATION: A painful pseudoparalysis of the shoulder indicates the implantation of a reversed total shoulder arthroplasty (rTSA) to reduce pain and restore active motion...

INTRODUCTION: The combination of traumatic brain injury (TBI) and long-bone fracture leads to increased formation of callus and mineral density in wild-type (WT) mice. However, this effect was not detected radiologically in leptin-deficient mice. Due to the complex interactions between hormonal and bone metabolism and the important role of leptin in this setting, our aim was to investigate morphologic properties and the tissue composition in the fracture callus comparing WT and leptin-deficient mice...

We report a new surgical technique of intrascleral posterior chamber intraocular lens (PC IOL) fixation using a newly developed hook-shaped haptic IOL (NX-70CH) and a 25-gauge loop-shaped haptic manipulator. Previous techniques of intrascleral PC IOL fixation had 2 major technical challenges; that is, externalization of the haptic and fixation of the haptic into the scleral tunnel. The new IOL and manipulator can facilitate externalization and secure fixation of the IOL haptic and can be used for suture fixation or implantation in the capsular bag in cases with presumed subluxated lens...
