Tornier HRS (Humeral Reconstruction System) Study (REVIVE)

This is an international, single arm, multicenter, prospective follow-up, non-significant risk, Post-Market Clinical Follow-up (PMCF) study. Data will be collected for the commercially available Tornier HRS (HUMERAL RECONSTRUCTION SYSTEM) shoulder system in both the anatomic and reversed configurations. Retrospective inclusions are allowed: study patients may be enrolled up to 3 months after date of surgery provided that the necessary pre-operative (baseline) and surgery data are accessible. Follow-up visits conducted from 3-month post-surgery onward must be prospective. The purpose of this study is to collect data needed to satisfy the European Union (EU) Medical Device Regulation (MDR) clinical post-market surveillance (PMS) and reporting requirements, and to support future regulatory submissions and peer-reviewed publications on device performance and safety.

Diaphragm-Sparing Regional Anesthesia Techniques for Shoulder Surgery

This study will compare two regional anesthesia techniques for shoulder surgery and evaluate their effects on diaphragmatic function. The standard regional anesthesia technique for shoulder surgery is the interscalene brachial plexus block (ISB), which provides effective analgesia but is frequently associated with ipsilateral hemidiaphragmatic paresis due to phrenic nerve involvement. An alternative diaphragm-sparing strategy is the combination of a suprascapular nerve block (SSNB) and an infraclavicular brachial plexus block (ICB), which may reduce the risk of diaphragmatic dysfunction while maintaining effective analgesia for shoulder surgery. All participants will receive ultrasound-guided regional anesthesia prior to surgery and will be randomly assigned to one of two groups: Group 1: Interscalene brachial plexus block Group 2: Suprascapular nerve block combined with infraclavicular brachial plexus block The primary aim of this study is to determine whether the diaphragm-sparing technique reduces the incidence of hemidiaphragmatic paresis while providing analgesia comparable to the standard interscalene block. Diaphragmatic movement will be assessed using ultrasound before and after block placement. Secondary outcomes include postoperative pain intensity, opioid consumption, pulmonary function parameters, and block-related complications.

Perform Humeral System Study

This study is an international, single arm, multicenter, prospective, non-significant risk, Post-Market Clinical Follow-up study, which is designed to collect safety and performance data at baseline, surgery, immediate post-op and annually through 10 years post-operation. Data collected from this study will be used for purposes, including but not limited to, Post-Market Surveillance, peer-reviewed publications, education materials, regulatory submissions, and/or product development.

FX Shoulder Prospective Clinical Study

Prospective Multi-Center Registry on study subjects with implanted devices marketed and legally commercialized in the USA by FX Shoulder Solutions.

Shoulder iD™ Primary Reversed Glenoid Outcomes Clinical Study

The goal of the Shoulder iD™ Primary Reversed Glenoid Outcomes Clinical Study is to collect safety and performance data on the commercially available Shoulder iD™ Primary Reversed Glenoid device. The study will learn about standard device use in adult patients who have a functional deltoid muscle and massive and non-repairable rotator cuff tear. The main questions it aims to answer are: * What is the average improvement in patient-reported shoulder function after 2 years when compared to before the surgery, and * What is the rate of surgical revisions needed over a 10 year period Patients will be asked to will be asked to regularly attend their check-up visits with their surgeon (including having x-rays or CT images taken to check their shoulder and implant), to complete questionnaires to report how their shoulder is doing, and to tell their surgeon when they notice any changes.

The Effect of Micro Fragmented Adipose Tissue (MFAT) on Shoulder Osteoarthritis

This is a non-surgical trial comparing the clinical and functional outcomes of patients with osteoarthritis treated with Intra-articular injection of Micro Fragmented Adipose Tissue versus conventional therapy of intra-articular injection of corticosteroid.

TESS V3 Modular Total Shoulder System PMCF

This is a multicenter, retrospective and prospective, non-controlled post market surveillance study. The objectives of this study are to confirm safety, performance and clinical benefits of the T.E.S.S.® Version 3 Anatomic and Reverse Modular Total shoulder prosthesis and its instrumentation.

Prophylactic Conjoint Tendon Lengthening During Reverse Shoulder Arthroplasty Outcomes

Some patients may experience persistent pain in the front of their shoulder after reverse shoulder replacement. One of the possible reasons for this is that the surgery causes a change in the alignment of the shoulder joint, which may cause increased tension and compression on one of the biceps tendon called the conjoint tendon. The purpose of this study is to evaluate whether conjoint tendon lengthening, a surgical procedure that involves cutting and lengthening the conjoint tendon in order to reduce tension and compression, is able to prevent or reduce the risk of anterior shoulder pain at one year after surgery.

DenCT Shoulder Bone Quality Evaluation

The objective of the study is to evaluate the preoperative bone quality assessment based on CT to later establish a scale for the decision of stemless shoulder arthroplasty.

Embo Registry; National Registry for Artery Embolization

Embo Registry is a retrospective and prospective observational study to evaluate real world effectiveness and the use of Artery Embolization as a treatment for chronic pain with patients that have osteoarthritis and localized pain to provide symptomatic relief. This study is to determine the efficacy and validity of procedure and that following procedure patients had decreased pain and improved quality of life.

TSA v RSA in Osteoarthritic Shoulders With Greater Than 15 Degrees of Retroversion

This study will compare total shoulder arthroplasty (TSA) with an augmented glenoid component and reverse shoulder arthroplasty (RSA) procedures, in participants with advanced glenohumeral osteoarthritis aged 65 years and older, who also present with greater than 15 degrees of glenoid retroversion, in the context of a prospective, randomized controlled trial to determine the optimal treatment in this patient population.

FX Shoulder Solutions Retrospective / Prospective Clinical Study

Subjects implanted with the shoulder replacement medical devices manufactured by FX Shoulder Solutions and distributed by FX Shoulder Solutions.

Autologous Adipose Tissue-Derived Mesenchymal Stem Cells (AdMSCs) for Osteoarthritis

This is a phase 2 open-label, 6 arms (1 study group and 1 control group for each joint category), randomized control group clinical study with 300 subjects diagnosed with osteoarthritis of knees (n=100), hips (n=100) and shoulders (n=100). The study subjects will be evaluated for disease-associated severity according to symptoms, such as pain, mobility, daily active life, and functions using arthritis society established specific measurement tools related to the joints (KOOS and KSS for OA-knees: HOOS and HHS for OA-hips and ASES and CSS for OA-shoulders).
