Do the humeral radiographic changes at 5-year follow-up affect the clinical outcomes of press-fit humeral stems in primary reverse shoulder arthroplasties?

Introduction: The purposes of this study were to analyze and compare the functional outcomes and radiological changes around the press-fit humeral components in two contemporary medialized reverse total shoulder arthroplasty (RTSA) systems at a minimum of 5-year follow-up.

Materials And Methods: Between December 2003 and December 2015, 249 consecutive RTSAs were performed at our hospital. Of these, 68 primary uncemented RTSA met our inclusion criteria.

Elongation of the brachial plexus after reverse shoulder arthroplasty: an anatomical study.

Introduction: The use of reverse shoulder arthroplasty (RSA) is becoming more extended and its clinical results are good or excellent according to the literature. The main biomechanical characteristic of RSA is that it lowers and medializes the centre of rotation of the shoulder causing an arm lengthening. Although the number of neurological complications is low (5%), there are more neurophysiological changes in the brachial plexus with RSA than with the anatomic shoulder arthroplasty.

Dislocation after reverse total shoulder arthroplasty using contemporary medialized modular systems. Can we still consider it such a frequent complication?

Introduction: Improvement in reverse total shoulder arthroplasty (RTSA) prosthesis and technique has reduced the initially high complication and revision rates associated with this implant. However, instability continues to be a leading cause of reoperation after RTSA, being related in previous studies with medialized designs. The aim of this study was to determine the dislocation rate with the employment of two medialized modular systems of RTSA in our institution.

Cerclage wire fixation of trochanteric osteotomies in complex hip revision: our experience and comparison with cable-plate fixation.

Introduction: Osteotomy of the greater trochanter is a commonly used procedure in complex revision hip arthroplasty in order to achieve a wide exposure to the femoral stem and acetabular components. There is no clinical evidence in favour of a specific fixation method. The aim of this study was to compare cable-plate with figure-of-eight cerclage wire fixation in patients requiring a trochanteric "slide" osteotomy.

Enhancement of in vivo supraspinatus tendon-to-bone healing with an alginate-chitin scaffold and rhBMP-2.

Introduction: Rotator cuff disorders present a high retear rate despite advances in surgical treatment. Tissue engineering could therefore be interesting in order to try to enhance a more biological repair. RhBMP-2 is one of the most osteogenic growth factors and it also induces the formation of collagen type I.

A clinical review of 11 cases of large-sized well-differentiated liposarcomas.

Well-differentiated liposarcomas of the extremities are one of the most frequent types of malignant soft tissue tumors in adults. These tumors are typically locally aggressive and show a tendency to recurrence after surgical excision even though they do not metastasize and very rarely dedifferentiate. Its clinical presentation is generally a progressively growing mass causing aesthetic, functional, or compressive symptoms depending on the tumor's size and localization.

A mid-term follow-up of Koutsogiannis' osteotomy in adult-acquired flatfoot stage II and "early stage III".

Introduction: Koutsogiannis' osteotomy has been widely described to treat adult-acquired flatfoot. However, few articles describe its midterm follow-up. Our aim was to study clinical and radiological outcomes at least one year after surgery and to analyze whether a combined procedure on the medial soft tissue affected these outcomes.

Paraneoplastic vasculitis associated to pelvic chondrosarcoma: a case report.

Vasculopathic syndromes have been associated with hematological and solid organ malignancies. The pathogenesis of these syndromes remains largely unknown and there are no biologic markers identified. Whether it is or is not a paraneoplastic syndrome is under discussion, the close temporal relationship of cancer and vasculitis suggests that these vasculitides are a paraneoplastic condition.

Benefits of early intramedullary nailing in femoral metastases.

Purpose: Pathological fractures of the long bones are common complications of metastatic disease; however, the outcome of different surgical techniques for the treatment of these fractures has not been clearly defined. The aim of this study was to evaluate differences in prophylactic and therapeutic intramedullary nailing in femoral metastasic implants.

Methods: Sixty-five patients with metastasis of the femur were analysed retrospectively (37 females; 28 males) between 1995 and 2011 (follow-up 15 months).
