Enriched mesoporous bioactive glass scaffolds as bone substitutes in critical diaphyseal bone defects in rabbits.

In the field of orthopedic surgery, there is an increasing need for the development of bone replacement materials for the treatment of bone defects. One of the main focuses of biomaterials engineering are advanced bioceramics like mesoporous bioactive glasses (MBG´s). The present study compared the new bone formation after 12 weeks of implantation of MBG scaffolds with composition 82,5SiO-10CaO-5PO-x 2.

In vivo behavior in rabbit radius bone defect of scaffolds based on nanocarbonate hydroxyapatite.

Bone defects treatment may require the use of biomaterials that behave as a support and promote bone regeneration. Limitations associated with the use of autografts and allografts make it necessary to design new synthetic bone substitutes. Some of the most promising biomaterials currently under investigation are based on nanocarbonate hydroxyapatite (nCHA).

Chronic Isolated Dorsal Dislocation of the Lunate. A Rare Presentation of Carpal Instability.

Unlabelled: Isolated dorsal lunate dislocation is a rare injury. Only one case has been reported previously in which the treatment was performed in the chronic stage. In this report, we present the case of a 49-year-old handworker male who presented a dorsal dislocation of the lunate after a traffic accident.

Acute complex instability of the elbow treated with internal joint stabilizer IJS-E System.

Introduction: Treatment of acute complex fracture-dislocation of the elbow has been associated with a high rate of complications. Internal Joint Stabilizer of the Elbow (IJSE) device appears as a valid option to optimize and improve our results.

Material And Methods: We present a retrospective case series of five patients treated at our institution with IJS-E System (Skeletal DynamicsR) from February 2019 to 2020.

The anconeus muscle revisited: double innervation pattern and its clinical implications.

Purpose: The aim of the present study is to describe in detail the morphology and innervation pattern of the anconeus muscle, bearing in mind clinical implications such as iatrogenic injuries during surgical elbow approaches.

Methods: A cadaveric study was performed; 56 elbows from 28 formalin-fixed cadavers belonging to the Anatomy Department of Universidad Complutense of Madrid were dissected. The triceps-anconeus nerve was located and dissected.

Arthrodesis of the thumb carpometacarpal joint using a quadrangular plate: surgical technique and long-term results of 70 patients.

Purpose: To assess the long-term results of trapeziometacarpal arthrodesis using a quadrangular plate, regarding clinical, radiological and functional outcomes, as well as development of complications.

Material And Method: From 2005 to 2015, 70 patients were treated at our institution for primary osteoarthrosis of thumb carpometacarpal joint performing a trapeziometacarpal arthrodesis. A total of 85 arthrodesis were carried out using a titanium quadrangular plate (Proflyle plate, Stryker, Kalamazoo MI, USA), without grafting in any case.
