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).

[Translated article] Design and comparison of bone substitutes. Study of in vivo behaviour in a rabbit model.

Aim: To compare the in vivo bone formation capacity of of biomaterials designed as bone substitutes with respect to iliac crest autograft, one based on carbonate hydroxiapatite and the other one on bioactive mesoporous glass.

Materials And Methods: Experimental study consisting on 14 adult female New Zeland rabbits where a critical defect was made in the rabbit radius bone. The sample was divided into four groups: defect without material, with iliac crest autograft, with carbonatehydroxyapatite scaffold, and with bioactive mesoporous glass scaffold.

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.

Trans-olecranon fracture dislocations: How should we treat them?

Background: Trans-olecranon fracture dislocations are the least frequent complex elbow instability. Proper surgical treatment should be performed to avoid postoperative complications.

Methods: A retrospective design study was performed.

[Mid-term complications of the monopolar, modular radial head prosthesis].

Introduction: The objective of this study is to assess the type, frequency and severity of complications after the implantation of the modular monopolar radial head prosthesis.

Material And Methods: Forty-seven patients with 48 radial head prostheses implanted between 2009 and 2017 were reviewed retrospectively. Patients were evaluated clinical and radiographically for a mean follow-up of 43.

Protocolised surgical treatment of terrible triad of elbow. Results and complications.

Background: Terrible triad of elbow is a complex lesion with a high rate of complications. Our goal is to analyse both clinical results and complications after performing protocolised surgery.

Material And Methods: The database of our hospital was used during 2005-2015, collecting characteristics of the patient, the fracture, the surgery and the associated complications, as well as functional results and range of mobility.

Scaphoid-trapezium hereditary coalition. A case report.

Carpal coalitions are relatively frequent between bones in the same carpal row. Coalitions between bones of different rows, however, are very uncommon. We present a case of bilateral intercarpal coalition between the trapezium and scaphoid as an incidental finding, confirming its hereditary origin since a parent has the same bilateral coalition.

Scaphoid Fractures treated with a volar percutaneous approach. Analysis and results in 92 cases.

Objective: Herbert type B1 and B2 scaphoid fractures can be treated by orthopaedic treatment or surgery. The aim of this study is to analyse results and complications of scaphoid waist fractures treated using the percutaneous volar approach.

Material And Method: We present a retrospective study of 92 patients, treated in our institution from 2006 to 2016 using a volar percutaneous fixation.

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.

A total of 85 arthrodesis were carried out using a titanium quadrangular plate (Proflyle plate, Stryker, Kalamazoo MI, USA), without grafting in any case.

Chronic ankle instability: Arthroscopic anatomical repair.
