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.

[Translated article] Efficacy of transplantation of lipoaspired mesenchymal stem cells in the treatment of chronic rotator cuff tears. Experimental model in rats.

Background And Aim: Rotator cuff tears emerge in approximately 30% of the population over 60 years of age. Arthroscopic surgical treatment of these lesions is the treatment of choice, however, despite the improved repair techniques, the rate of re-tears ranges between 11 and 94%. Therefore, researchers seek to improve the biological healing process through the use of different alternatives such as mesenchymal stem cells (MSCs).

The Spanish version of the Constant-Murley Shoulder Score: translation, cultural adaptation, and validity.

Background: The Constant-Murley Score (CMS) is one of the most employed tools for assessing shoulder function. It was first devised in 1987 for the English population and is now widely used internationally. However, it had yet to be cross-culturally adapted and validated to Spanish, which is the world's second-most native language.

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.

Nailing unstable pertrochanteric fractures: does size matters?

Introduction And Objectives: New generation cephalomedullary nails are, currently, widely used for the treatment of trochanteric proximal femoral fractures. This study aims to compare the midterm outcomes and complication rates in patients with unstable 31A2 fractures treated with two different lengths of nails.

Materials And Methods: Retrospective study including 123 pertrochanteric proximal femoral fractures 31A2 treated with Gamma3 nail between January/2017 and January/2019.

[Hallux metatarsophalangeal arthrodesis: retrospective comparison between blocked plate and cannulated screws].

Introduction: There are multiple methods and implants used for the metatarsophalangeal arthrodesis of hallux without evidence in favor of one or the other in the bibliography. The goal was to compare the clinical and radiological results of 2 methods and implants used in our center.

Material And Methods: Retrospective review of 37 feet between 2013 and 2017 (22 feet by plate and 15 by cannulated screws).

Is fibromyalgia a cause of arthroscopic subacromial decompression failure?

Unlabelled: Isolated arthroscopic subacromial decompression (IASD) is a widely used surgical procedure with high success rates. However, up to 25% of patients experience residual pain. It is unclear whether aberrant central nervous system processing of pain as described in fibromyalgia (FM) could have a detrimental effect on outcomes.

Management of pediatric tibial tubercle fractures: Is surgical treatment really necessary?

Fractures of the anterior tibial tubercle are infrequent lesions. They often occur in male adolescent athletes, usually in relation with sports involving powerful jumps. We present a retrospective study of 10 patients, with an average age of 15.

[Dislocation of the proximal hallux interphalangeal joint with interposition of a sesamoid bone: a blibliographic review].

The irreducible dislocation of the hallux interphalangeal joint is an infrequent condition and only a few cases have been described. It presents as dorsal dislocation with interposition of the sesamoid bone, which has the possibility of being radiologically undetectable. We present the case of a 29 year-old patient who, after a sports trauma sustained a hallux interphalangeal dislocation that went unnoticed for eight days.

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.

[Congenital knee dislocation: case report].

Congenital knee dislocation is an infrequent condition with unknown etiology. In some cases it occurs as an isolated condition, while in others it coexists with associated conditions or syndromes. The treatment of congenital knee dislocation is driven by the severity and flexibility of the deformity.

[Surgical treatment of malignant primary tumors of the pelvis on Ennekings zone II].

Introduction: Surgical treatment of malignant bone tumors of the pelvis with periacetabular involvement is constantly evolving. Even though acetabular reconstructions improve quality of life without impairing cancer control, they are not complication free. Our purpose is to describe the functional outcomes and surgical complications of different reconstructive techniques for Enneking zone II tumors.

Repair of rotator cuff injuries using different composites.

Aim: Rotator cuff repairs have shown a high level of re-ruptures. It is hypothesised that the use of rhBMP-2 in a carrier could improve the biomechanical and histological properties of the repair.

Material And Methods: Controlled experimental study conducted on 40 rats with section and repair of the supraspinatus tendon and randomisation to one of five groups: Group 1 (control) only suture; Group 2 (double control), suture and alginate-chitin carrier; Group 3 (alginate-control), the rhBMP-2 was added to the alginate; Group 4 (chitin-control) application of the rhBMP-2 to the chitin, and Group 5 (double sample): The two components of the carrier (alginate and chitin) have rhBMP-2.

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).
