Shoulder osteoarthritis

We report on a singular case of a unique form of post-traumatic reversal of the humeral head after humeral neck fracture, in which the pattern of collapse resulted in the formation of a native reverse polarity shoulder. In essence, the humeral head became a socket, and the glenoid rounded to become a head with well-preserved shoulder function. To our knowledge, this is the first case of an acquired shoulder deformity that bears a remarkable functional similarity to a prosthetic reverse polarity shoulder replacement...

BACKGROUND: Alcohol use disorder (AUD) is the most prevalent substance use disorder in the United States. However, the current literature on AUD as a preoperative risk factor for Total Shoulder Arthroplasty (TSA) outcomes is limited. The purpose of this study was to identify the association of AUD with revision rates and 90-day postoperative complications in TSA. METHODS: A retrospective study was conducted using the PearlDiver database. Patients diagnosed with AUD were identified...

INTRODUCTION: While several general questionnaires can be used to evaluate shoulder conditions, very few tools specifically evaluate the impact of shoulder osteoarthritis. The WOOS (Western Ontario Osteoarthritis of the Shoulder index) is a patient-reported outcome measure with excellent psychometric properties intended for patients suffering from shoulder osteoarthritis. Unfortunately, there is no validated French version of this questionnaire. OBJECTIVE: Produce a validated French version of the WOOS that is suitable for the Francophone populations of Europe and North America...

Osteoarthritis management primarily focuses on targeting pain. Conventional modalities for pain management include acetaminophen, non-steroidal anti-inflammatory drugs (NSAIDs), and intra-articular corticosteroid injections. However, these approaches may provide minimal pain relief and can be contraindicated for some patients, highlighting the ongoing need for alternative pain management. Colchicine, commonly used in the management of gout, has emerged as a potential option for pain management in osteoarthritis...

Introduction: Osteoarthritis (OA) and rotator cuff tear (RCT) pathologies have distinct scapular morphologies that impact disease progression. Previous studies examined the correlation between scapular morphology and glenohumeral joint biomechanics through critical shoulder angle (CSA) variations. In abduction, higher CSAs, common in RCT patients, increase vertical shear force and rotator cuff activation, while lower CSAs, common in OA patients, are associated with higher compressive force. However, the impact of the complete patient-specific scapular morphology remains unexplored due to challenges in establishing personalized models...

OBJECTIVE: Osteoarthritis affects over 5.4 million people in the United States. A common treatment is to perform intra-articular corticosteroid injections. However, the ideal steroid dose is unknown. This study aimed to pilot a corticosteroid injection protocol for primary glenohumeral OA. METHODS: We conducted a double blinded randomized feasibility pilot study. Patients with primary osteoarthritis of the glenohumeral joint were recruited and randomized to receive 20 ​mg, 40 ​mg, or 80 ​mg of triamcinolone...

BACKGROUND: Shoulder pain is one of the most common presentations in the orthopedic clinic. Multiple factors have been found to cause shoulder pain. Radiographs and ultrasound are widely available, relatively cheap modalities in assessing shoulder pain. The aim of this study is to assess the radiographic and sonographic imaging patterns of shoulder pain. METHODS: A descriptive prospective cross-sectional hospital-based study was conducted at the Department of Radiology of Tikur Anbessa Specialized Hospital among patients with shoulder pain that came for imaging from August 2021-January 2022...

A Segond fracture is a specific type of avulsion fracture involving the lateral aspect of the proximal tibia adjacent to the tibial plateau. Segond fractures are indicative of ligamentous injury in the knee. In this case report, a 29-year-old male delivery driver presented to the ED with acute onset right knee pain after losing control of his motorbike at low speed. Examination revealed significant effusion and medial and lateral joint line tenderness. An anterior-posterior radiograph of the knee showed a Segond fracture...

INTRODUCTION: Reverse total shoulder arthroplasty (RTSA) can result in varying amounts of humeral medialization or lateralization. The amount of medial or lateral change-in-arm-position can be predicted using 3D CT planning software. It is not clear if the preoperatively-predicted change-in-arm-position correlates with the actual, radiographically-measured change-in-arm-position or if predicted or actual change-in-arm-position correlates with patient-reported outcomes or complications...

BACKGROUND: Knowledge of premorbid glenoid parameters at the time of shoulder arthroplasty, such as inclination, version, joint line position, height, and width, can assist with implant selection, implant positioning, metal augment sizing and/or bone graft dimensions. The objective of this study was to validate a scapular statistical shape model (SSM) in predicting patient-specific glenoid morphology in scapulae with clinically relevant glenoid erosion patterns. METHODS: Computer tomography scans of 30 healthy scapulae were obtained and used as the control group...

Osteoarthritis is one of the most common diseases in veterinary medicine. There are various causes for joints developing OA, with some of them being well investigated, while others are still a matter of speculation. In this retrospective study we examined the prevalence of OA in the shoulder, elbow, hip and stifle joints in a clinic population of dogs older than 8 years, which were presented mostly due to orthopaedic complaints. Dogs were included in the study if one or more of the aforementioned joints was included in the radiographs...

This study aimed to assess the effect of the status of the tendon and patient factors on patient satisfaction after rotator cuff repair. Forty-six patients treated for tears with a minimum of 5-year follow-up were included. Gender, age, and active smoking status were recorded. Pain visual analogue scale, American Shoulder and Elbow Surgeons Standardized Shoulder Assessment Form, Simple Shoulder Test, and Single Assessment Numeric Evaluation were recorded preoperatively and at the last follow-up. Patients were divided into groups of highly satisfied (HS) and vaguely satisfied (VS) patients...

BACKGROUND: Controversy exists regarding the ideal humeral component version to optimize humeral rotation and patient outcomes in reverse total shoulder arthroplasty (rTSA). METHODS: Patients undergoing primary rTSA for rotator cuff tear arthropathy, a massive rotator cuff tear, or primary osteoarthritis with a rotator cuff tear were randomized to placement of the humeral component in neutral version or 30° of retroversion. Shoulder active range of motion and strength and visual analog scale (VAS) pain, American Shoulder and Elbow Surgeons (ASES), and Patient-Reported Outcomes Measurement Information System Global 10 (PROMIS-10) scores were collected up to 2 years postoperatively...

Trapeziometacarpal osteoarthritis (TMC-OA) reduces the range of motion (ROM) of the thumb. However, the kinematic change achieved through surgical treatment remains unclear. Therefore, to quantify the kinematic change following TMC-OA surgery, we performed a three-dimensional motion analysis of the thumb using an optical motion capture system preoperatively and 1 year postoperatively in 23 patients with TMC-OA scheduled for arthrodesis (AD) or trapeziectomy with suspensionplasty (TS). Eighteen hands of nine healthy volunteers were also included as controls...

INTRODUCTION: Physical therapy (PT) is a described first-line treatment option for glenohumeral arthritis, but its efficacy for treating this spectrum of disease is not well understood. The purpose of this study is to evaluate the opinions of expert providers-orthopedic surgeons and physical therapists-regarding the utility of PT in treating glenohumeral arthritis in different stages of radiographic severity. Our goal is to identify areas of interprofessional majority agreement as well as areas without agreement that warrant further investigation...

Background: The primary cause of medium- to long-term complications in reverse shoulder arthroplasty (RSA) is the failure of the glenoid component. The purpose of this study was to evaluate both the achievement of planning through computer-assisted navigation and the clinical outcomes at a minimum follow-up (FU) of 12 months. Methods: From December 2019 to December 2022, 57 Equinoxe RSAs with computer-assisted navigation were performed. The average age was 72.8 ± 6.6 years. Using the Orthoblue software, the version and inclination of the glenoid were evaluated from a preoperative CT scan, and planning was performed...

BACKGROUND: Shoulder pain is a leading cause of disability. Occupations requiring high upper extremity demands may put workers at greater risk of shoulder injury and resulting pain. We examined associations of occupation with shoulder pain and upper extremity disability in the Johnston County Osteoarthritis Project. METHODS: Work industry and occupational tasks for the longest job held were collected from participants. At follow-up ranging from 4-10 years later, participants were asked about shoulder symptoms (pain, aching, or stiffness occurring most days of 1 month in the last year) and given a 9-item, modified Disabilities Arm Shoulder and Hand (DASH) questionnaire to categorize disability from 0-4 (none-worst)...

Shoulder arthroplasty has significantly gained popularity in orthopedic surgery, driven by progress in prosthesis design and surgical techniques. This study explored the epidemiology of shoulder arthroplasty, analyzing healthcare data from 2012 to 2022 for primary osteoarthritis of the shoulder. The data included patient demographics and types of surgical procedures. Data analysis indicates a higher utilization rate of reverse total shoulder arthroplasty (RTSA; n = 41,251) over total- (TSA; n = 18,679) and hemiarthroplasty (HSA; n = 12,827) for primary shoulder osteoarthritis...

OBJECTIVE: Hyaluronic acid (HA) in synovial fluid (SF) contributes to boundary lubrication with altered levels in osteoarthritis (OA) and rheumatoid arthritis (RA). SF extracellular vesicles (EVs) may participate in arthritis by affecting inflammation and cartilage degradation. It remains unknown whether HA and EVs display joint-specific alterations in arthritic SFs. DESIGN: We investigated the numbers and characteristics of HA-particles and large EVs in SF from knees and shoulders of 8 OA and 8 RA patients and 8 trauma controls, and in plasma from 10 healthy controls and 11 knee OA patients...

Background: Wrist arthroplasty is increasingly offered to patients with symptomatic wrist arthritis as an alternative to wrist arthrodesis. The purpose of this study was to present our outcomes with the ReMotion™ wrist arthroplasty in a consecutive series of patients with wrist arthritis from non-inflammatory conditions. Methods: Thirteen (eight women, nine dominant wrists) patients, 68 (44-85) years of age with advanced radiocarpal arthritis due to SLAC/SNAC (11) and Kienbock disease (2) had a ReMotion™ (Stryker, Michigan, USA) wrist arthroplasty implanted, and were prospectively followed for 7 (4-9) years...
