MAÏA Trapeziometacarpal Joint Arthroplasty: Clinical and Radiological Outcomes of 76 Patients With More Than 10 Years of Follow-Up.

Purpose: Trapeziometacarpal (TMC) joint replacement has become a valid option in the therapeutic arsenal of TMC joint osteoarthritis in Europe. Good mid-term results of the MAÏA TMC joint prosthesis suggested that it is a reliable procedure. This study aimed to assess the long-term results of this modular uncemented ball-and-socket hydroxyapatite-coated implant.

Non-operative management of humeral periprosthetic fracture after stemless shoulder arthroplasty.

Purpose: Periprosthetic fractures around a stemless implant often involve lesser and greater tuberosities with a well-fixed implant in the metaphysis. This exposes the surgeon to unique questions and challenges as no surgical option (open reduction and internal fixation or revision to a stem) appears satisfactory to address them. Purpose of this study was to evaluate the clinical outcomes after non-operative management of periprosthetic fractures after stemless shoulder arthroplasty.

Heterotopic ossification of the shoulder after arthroscopic rotator cuff repair: A case report.

Introduction And Importance: Heterotopic ossification (HO) often arises in response to trauma, prior surgical procedures, neurological injuries, or burns. However, its presentation as a complication of shoulder arthroscopy is uncommon and can sometimes lead to functional impairment. In our study, we report a case of HO complicating rotator cuff repair, along with details of the surgical treatment and subsequent progression.

Stemless shoulder arthroplasty.

The concept of stemless shoulder arthroplasty was born in 2005. It is now a valid option in the context of either anatomical or reverse shoulder replacement. Several questions have come up over our 15 years of using this system: How was the stemless shoulder arthroplasty concept born? It was motivated by a desire to have epiphyso-metaphyseal fixation using a corolla-shaped impacted anchor design.

Arthroscopic Latarjet procedure and suture-button fixation: can we predict nonunion early?

Background: The arthroscopic Latarjet procedure is a technically challenging technique that provides well-known results. The first series reported fixation with screws. An alternative fixation technique has been proposed, using a button, to improve the reproducibility and to decrease the complications due to screws.

The INCA® implant to treat isolated scaphotrapeziotrapezoid osteoarthritis: Preliminary results at a minimum 2 years' follow-up.

We report results with the INCA® distal scaphoid pole resurfacing implant anchored within the scaphoid for isolated scaphotrapeziotrapezoid osteoarthritis. Thirty-five implants in 27 patients (mean age, 69 years) were retrospectively included with a minimum follow-up of 2 years. Outcome criteria were pain (VAS), PROMs (QuickDASH, PRWE and MMWS), wrist motion, pinch and grip strength, and radiographic assessment.

Trapeziometacarpal prostheses.

In 1970, Jean-Yves de la Caffinière developed the first trapeziometacarpal (TMC) joint prosthesis, a ball-and-socket design based on hip replacement implants. From 1970 to 1990, the first generation of cemented prostheses was developed. At that time, trapeziectomy, with tendon interposition or suspension arthroplasty, and Swanson silastic spacers remained the most widely used surgical procedures for thumb basal joint arthritis.

Osteoarthritis of the shoulder in under-50 year-olds: A multicenter retrospective study of 273 shoulders by the French Society for Shoulder and Elbow (SOFEC).

Introduction: Osteoarthritis (OA) of the shoulder in under-50 year-olds is rare, and treatment is delicate. Shoulder replacement incurs frequent long-term risk of progression and a high revision rate, making it unsuited to young active patients. The aim of the present study was to determine the epidemiology of shoulder OA in under-50 year-olds and to assess the clinical results of the various treatment options.

Clinical outcomes after multiligament injured knees: medial versus lateral reconstructions.

Purpose: The purpose of this study was to analyse the clinical outcomes of multiligament injured knees with respect to the medial collateral ligament and posteromedial corner (PMC) repair or reconstruction versus the posterolateral corner (PLC) reconstruction in patients operated according to a codified surgical protocol.

Methods: Patients were divided into two groups depending on whether PMC or PLC was injured. Cruciate ligaments as well as PMC or PLC were reconstructed/repaired in a one-stage procedure.

Stemless shoulder prosthesis for treatment of proximal humeral malunion does not require tuberosity osteotomy.

Purpose: When the proximal humeral anatomy is altered because of malunion, shoulder arthroplasty is a challenge for the orthopaedic surgeon, and tuberosity osteotomy should be avoided whenever possible. The purpose of this study was to investigate the clinical and radiological outcomes of anatomic stemless shoulder arthroplasty in cases of malunion. We hypothesized that a stemless prosthesis can be implanted without performing tuberosity osteotomy.

The TESS reverse shoulder arthroplasty without a stem in the treatment of cuff-deficient shoulder conditions: clinical and radiographic results.

Background: Reverse total shoulder arthroplasty (RSA) is a recent concept that enables good functional outcomes in cases of massive rotator cuff tear and cuff tear arthropathy. Design parameters influence the functional results and complications. The purpose of this study is to present the results of a novel RSA, the Total Evolutive Shoulder System (TESS; Biomet, Warsaw, IN, USA), based on a reverse corolla without a stem.

Biometry of the calcaneocuboid joint: biomechanical implications.

Precise biometric data of calcaneus, cuboid bones and calcaneocuboid joint are not alluded to in textbooks of anatomy. This study focussed on the biometry of 50 calcanei, 30 cuboid dry bones, and anatomical specimens of 21 transverse tarsal joints. Measurement of the length, width, angular orientation, contact surface and radius of curvature, rolling band of the joints surfaces according to the main axes were performed.

[Nerve transfer in isolated deltoid palsy: branch of the long head of the triceps to the axillary nerve].

Aim: Nerve transfer of the nerve branch to long head of triceps onto the axillary nerve has joined the therapeutic armamentarium for isolated deltoid paralysis cases. We report our experience in the case of a non-excisable neuroma of the axillary nerve at its origin from the posterior cord.

Methods: Eight patients of average age 28 (15-38) were included in a retrospective study with one operating surgeon.

Role of haeme oxygenase-1 in resolution of oxidative stress-related pathologies: focus on cardiovascular, lung, neurological and kidney disorders.

The present review examines the role of the cytoprotective enzyme haeme oxygenase-1 (HO-1) in adaptive responses to inflammatory disease and explores strategies for its clinical use, with particular emphasis on use of therapeutic use of the enzyme using phytochemical inducers of HO-1 such as extracts of Ginkgo biloba, curcumin, and flavonoids extracted from seeds of the sour cherry (Prunus cerasus). This laboratory has identified strategies by which combinations of dietary phytochemicals may be configured to synergistically strengthen immunoregulatory mechanisms that normally prevent inflammation from leading to disease. A major focus of this research initiative has been HO-1, which is capable of substantially reducing oxidative stress by several mechanisms.

Biometry of bone components in the talonavicular joint: a cadaver study.

Introduction: Exhaustive biometric data of the talus and the navicular bones have not been reported in the classical anatomy treatises.

Hypothesis: The radiographic measurements, being variable according to the X-ray beam inclination, have no real value. This biometric analysis aimed to specify the characteristics of the constitutive bone components of the talonavicular joint.

Lactic acid bacteria biomass monitoring in highly conductive media by permittivity measurements.

Recent technological improvements have extended the application range of permittivity biomass measurements to bacterial fermentations in highly conductive media. With Lactobacillus casei, the effective biomass detection sensitivity of the FOGALE Biomass System is around 0.2 g/l (0.
