Subtrochanteric Fractures of The Femur: May a Short Nail Be a Reliable Option?

Objectives: Treatment of subtrochanteric fractures of the proximal femur may be challenging due to their anatomical and biomechanical features. Intramedullary nails are the most frequently used devices, although there is no consensus concerning their optimal length. The aim of this study is to compare the functional and radiological outcomes of the fragility subtrochanteric fractures treated with short versus long cephalomedullary nails.

Background: Few studies compare complications and results in ceramic-ceramic (CeCe) metal-on-crosslink polyethylene (Me-XLPE) hip prosthesis.

Methods: of 2 series of hydroxyapatite-coated Furlong Active implanted with identical protocol by 1 surgeon in 1 hospital from 2006 to 2014.

Bearing Surface: CeCe (Biolox Forte/Delta) in 35 cases of 53.

Diagnostic Accuracy of Magnetic Resonance Images and Weight-Bearing Radiographs in Patients With Arthroscopic-Proven Medial Osteoarthritis of the Knee.

Aims: The aim of this study is to analyze the diagnostic value of weight-bearing radiographs, magnetic resonance images (MRI), and the combination of both in osteoarthritic knees when using arthroscopic findings as the "gold standard" to compare with.

Methods: A total of 59 patients were studied because of chronic pain in 1 of their knees. Radiographs were classified according to Kellgren-Lawrence scale.

Early efficacy evaluation of mesenchymal stromal cells (MSC) combined to biomaterials to treat long bone non-unions.

Background And Study Aim: Advanced therapy medicinal products (ATMP) frequently lack of clinical data on efficacy to substantiate a future clinical use. This study aims to evaluate the efficacy to heal long bone delayed unions and non-unions, as secondary objective of the EudraCT 2011-005441-13 clinical trial, through clinical and radiological bone consolidation at 3, 6 and 12 months of follow-up, with subgroup analysis of affected bone, gender, tobacco use, and time since the original fracture.

Patients And Methods: Twenty-eight patients were recruited and surgically treated with autologous bone marrow derived mesenchymal stromal cells expanded under Good Manufacturing Practices, combined to bioceramics in the surgical room before implantation.

Editorial. The Challenges of Orthopaedic Trauma in Spain.

Spain is considered the healthiest nation in the world, due to lifepromoting aspects such as good diet, care facilities and a favourable family environment. However, although increased life expectancy is an indicator of development, it may have a negative impact on the other two variables of health service efficiency, namely health expenditure per capita and its relative weight in Gross Domestic Product.

Validation of a long bone fracture non-union healing score after treatment with mesenchymal stromal cells combined to biomaterials.

Unlabelled: The available scores to clinically evaluate fracture consolidation encounter difficulties to interpret progression towards consolidation in long-bone non-union, particularly when incorporating biomaterials in the surgical treatment. The aims of this study were to validate the REBORNE bone healing scale in tibia, humerus and femur non-unions treated by a combination of mesenchymal stromal cells (MSCs) and biomaterials, through the interclass correlation (ICC) among raters, and to define reliability and concordance in anteroposterior and lateral radiographs, compared to computed tomography (CT).

Methods: Twenty-six cases from the EudraCT 2011-005441-13 clinical trial underwent bone healing evaluation, if at least 3 out of 4 cortical views clearly identified.

Staphylococcus aureus Prosthetic Joint Infection Is Prevented by a Fluorine- and Phosphorus-Doped Nanostructured Ti-6Al-4V Alloy Loaded With Gentamicin and Vancomycin.

Prosthetic joint infection (PJI) is one of the most devastating complications in orthopedic surgery. One approach used to prevent PJI is local antibiotic therapy. This study evaluates the antibiotic release, in vitro cytocompatibility and in vivo effectiveness in preventing PJI caused by Staphylococcus aureus (S.

Urine Aluminum Concentration as a Possible Implant Biomarker of Infection Using a Fluorine- and Phosphorus-Doped Ti-6Al-4V Alloy with Osseointegration Capacity.

Joint prosthesis failure is mainly related to aseptic loosening and prosthetic joint infections, both associated with high morbidity and a substantial cost burden for patients and health systems. The development of a biomaterial capable of stimulating bone growth while minimizing bacterial adhesion would reduce the incidence of prosthetic failure. Using an in vivo rabbit model, this study evaluates the osseointegration effect of the fluorine (F)- and phosphorus (P)-doped bottle-shaped nanostructured (bNT) Ti-6Al-4V alloy and effectiveness of monitoring urine aluminum concentration to determine the presence of infection in Ti-6Al-4V implants.

Proximal Femoral Bone Regeneration After an Uncemented Hydroxyapatite-coated Long-stem in Revision Hip Surgery.

Background: Bone remodelling with lateral femoral cortex thinning is a major concern after extensively porous-coated long-stem in revision surgery. Extensive hydroxyapatite coated long-stems were introduced to improve osseointegration, but bone remodelling changes have not been quantified.

Objective: The question of whether bone remodelling changes from extensive hydroxyapatite-coated long stems influence the durability of femoral revision, clinical outcome is assessed in follow-up radiographs.

One- and two-stage surgical revision of peri-prosthetic joint infection of the hip: a pooled individual participant data analysis of 44 cohort studies.

One-stage and two-stage revision strategies are the two main options for treating established chronic peri-prosthetic joint infection (PJI) of the hip; however, there is uncertainty regarding which is the best treatment option. We aimed to compare the risk of re-infection between the two revision strategies using pooled individual participant data (IPD). Observational cohort studies with PJI of the hip treated exclusively by one- or two-stage revision and reporting re-infection outcomes were retrieved by searching MEDLINE, EMBASE, Web of Science, The Cochrane Library, and the WHO International Clinical Trials Registry Platform; as well as email contact with investigators.

Feasibility and safety of treating non-unions in tibia, femur and humerus with autologous, expanded, bone marrow-derived mesenchymal stromal cells associated with biphasic calcium phosphate biomaterials in a multicentric, non-comparative trial.

Background: ORTHO-1 is a European, multicentric, first in human clinical trial to prove safety and feasibility after surgical implantation of commercially available biphasic calcium phosphate bioceramic granules associated during surgery with autologous mesenchymal stromal cells expanded from bone marrow (BM-hMSC) under good manufacturing practices, in patients with long bone pseudarthrosis.

Methods: Twenty-eight patients with femur, tibia or humerus diaphyseal or metaphyso-diaphyseal non-unions were recruited and surgically treated in France, Germany, Italy and Spain with 100 or 200 million BM-hMSC/mL associated with 5-10 cc of bioceramic granules. Patients were followed up during one year.

Effect of different agents with potential antibiofilm activity on antimicrobial susceptibility of biofilms formed by Staphylococcus spp. isolated from implant-related infections.

An in vitro study aimed to evaluate the effect of N-acetyl cysteine (NAC) or sub-ICs of erythromycin on antimicrobial susceptibility of staphylococcal biofilms was performed. Staphylococcus aureus and Staphylococcus epidermidis strains were isolated from patients with prosthetic joint infections using a previously published sonication procedure. Conventional susceptibility studies were performed using microdilution according to the CLSI procedures.
