Shoulder replacement

Apert syndrome, first described in the literature by a French pediatrician Eugene Apert, is a rare congenital form of acrocephalodactyly with autosomal dominant inheritance. Classically, this syndrome is characterized by craniosynostosis, midface hypoplasia, and symmetrical syndactyly of hands and feet resulting from embryonic anomalies during the third week of gestation. It is also associated with a variety of abnormalities of the viscera, involving the neurological, genitourinary, and cardiorespiratory systems...

BACKGROUND: Fractures of the distal humerus are a common fragility fracture in older adults. The purpose of this study was to systematically review the literature to produce pooled estimates of the outcomes of treatment using total elbow arthroplasty (TEA), open reduction and locking plate fixation (ORIF), hemiarthroplasty or with conservative management. METHODS: A systematic review of PUBMED and EMBASE databases was conducted for studies reporting outcomes of intra-articular fractures in older adults...

INTRODUCTION: Sex disparities in presentation of osteoarthritis and utilization of joint replacement surgery (JRS) have been demonstrated. The role of patients' unique perspectives on JRS on their treatment decisions is poorly understood. METHODS: JRS candidates who were offered JRS but declined surgical treatment completed this survey. Survey questions included demographic information, patient experiences and current opinions around JRS, patient experiences with providers, goals and concerns, and barriers to JRS...

INTRODUCTION: Shoulder arthroplasties have been demonstrated to provide reliable pain relief as well as functional benefits. The advent of the reverse shoulder arthroplasty allowed for expanded indications for shoulder replacement. Several studies comparing the outcomes of anatomic and reverse total shoulder arthroplasties have demonstrated decreased range of motion in the reverse arthroplasty cohort, especially in internal rotation. The authors hypothesized that slight modifications to the humeral component of a reverse shoulder arthroplasty could result in increased impingement free range of motion without significant sacrifices to stability...

OBJECTIVE: Primary joint arthroplasty (JA) is one of the most common operating room (OR) procedures, with knee and hip arthroplasties being listed in the top five most frequent OR procedures and while not as common, shoulder arthroplasties are increasing at greater rates than knee and hip arthroplasties. Periprosthetic joint/shoulder infections (PJI/PSI) are a devastating complication of primary JAs with infection prevention deemed as the single most important strategy in combating them...

Built upon the shoulders of graph theory, the field of complex networks has become a central tool for studying real systems across various fields of research. Represented as graphs, different systems can be studied using the same analysis methods, which allows for their comparison. Here, we challenge the widespread idea that graph theory is a universal analysis tool, uniformly applicable to any kind of network data. Instead, we show that many classical graph metrics-including degree, clustering coefficient, and geodesic distance-arise from a common hidden propagation model: the discrete cascade...

BACKGROUND: The design of reverse shoulder arthroplasty (RSA) implants has evolved significantly over the past 50 years. Today there are many options available that differ in design of the glenoid and humeral components, fixation methods, sizes and modularity. With respect to the humeral component the literature has generally focused on the differences between inlay and onlay designs and the potential impact on outcomes. However, inlay and onlay design represents only one factor of many...

INTRODUCTION: Revision shoulder arthroplasty can be challenging. One of the main considerations for surgeons is the type of implant that was placed in the initial surgery. Anatomic shoulder arthroplasty (ASA) is used for cases of osteoarthritis as well as for fractures of the humeral head. Hemiarthroplasty can be used for complex proximal humerus fractures. The purpose of this study is to determine whether there is a difference in clinical and radiographic outcomes between patients that failed primary fracture hemiarthroplasty (FHA), or ASA for osteoarthritis and then required reoperation with a conversion to reverse shoulder arthroplasty (RSA)...

BACKGROUND: Reverse total shoulder arthroplasty (rTSA) has gained popularity in recent years and is indicated for a wide variety of shoulder pathologies. However, use of rTSA in patients with "weight-bearing" shoulders that support wheelchair use or crutches has higher risk. The aim of this study was to assess the results of rTSA in such patients. METHODS: Between 2005 and 2014, 24 patients (30 shoulders) with weight-bearing shoulders were treated with rTSA at our unit...

Since its inception in 1893, shoulder arthroplasty has become an increasingly common surgical procedure. Between 1998 and 2008, shoulder arthroplasty procedures increased by nearly 28,000 cases per year in the United States alone and is the fastest growing joint replacement surgery among all joint. Despite its advantages, shoulder arthroplasty is often accompanied by significant postoperative pain. Pain control continues to be a major concern in patient management, as it impacts operative costs, postoperative mobility, length of hospital stay, patient satisfaction, and overall surgical outcomes...

BACKGROUND: Reverse shoulder arthroplasty (RSA) with concurrent latissimus dorsi transfer (LDT) is a potential treatment option for restoration of external rotation (ER). Biomechanical studies have emphasized the importance of the insertion site location for achieving optimal outcomes. In this systematic review and meta-analysis, we aim to describe what insertion sites for LDT are utilized during concomitant RSA and their associated clinical outcomes. METHODS: A systematic review and meta-analysis were performed per PRISMA guidelines...

BACKGROUND: Recovery from anatomic shoulder arthroplasty may be enhanced in patients with good mental health and the resilience to participate in the prescribed postoperative rehabilitation program. To test this concept, we utilized validated and reliable scales in determining whether resilience and mental health are associated with the outcome of anatomic arthroplasty. METHODS: 399 patients (195 ream and run (RnR) and 204 anatomic total shoulder (aTSA)) were surveyed at a mean follow-up of 6...

BACKGROUND AND OBJECTIVE: Crucial to the success of any total or reverse shoulder arthroplasty (RSA) is the stability of the glenoid component fixation. Instability can lead to early implant failure and unsatisfactory results. Patients often present with varying forms of glenoid bone loss (GBL) in both the primary and revision settings, which can be a challenge for the treating surgeon. Severe cases of GBL can increase the risk of potential complications and diminish implant longevity...

PURPOSE: The healthcare industry is a significant contributor to single-use plastic waste, particularly in the operating room (OR). This study aims to assess the volume of plastic waste generated during total hip, knee, and shoulder arthroplasty in the OR and identify areas for improvement. METHOD: A prospective transversal study at a tertiary hospital was conducted. All total knee arthroplasty (TKA), total hip arthroplasty (THA), and reverse shoulder arthroplasty (RSA) from April to July 2021 were included...

Background Inaccurate positioning of the glenoid component has been well described as the most common cause of early failure following a reverse shoulder arthroplasty (RSA). Among the latest developments in operative technique, three-dimensional preoperative planning and navigation intraoperative systems have been developed to improve the accuracy of the baseplate positioning during RSA. The primary purpose of this retrospective analysis was to investigate the mid-term results of patients who underwent an elective RSA or for acute highly comminuted proximal humerus fractures...

INTRODUCTION: Total shoulder arthroplasty (TSA) and hemiarthroplasty (HA) are used in the management of end stage glenohumeral arthritis. Improvement in shoulder function and resolution of symptoms are high priorities for patients. The aim of this study was to compare patient-reported outcome measures (PROMs) following TSA and HA. METHOD: Records from the National Joint Registry of England, Wales, Northern Ireland and the Isle of Man were linked to the PROMs dataset...

INTRODUCTION: Aseptic loosening is one of the most common complications of total elbow arthroplasty (TEA). Modern implants, such as the Nexel, have been designed in an attempt to decrease loosening. The present study aims to report implant survivorship, radiographic assessment of loosening and lucency, and patient-reported outcome measures (PROMs) in patients treated with the Nexel TEA at mid-term follow-up. METHODS: Consecutive series of adult patients underwent TEA using the Nexel by a single surgeon via standardized technique...

BACKGROUND: The current study aimed to determine the changes in pre-and post-operative Pittsburg sleep quality index (PSQI) and Tampa scale of kinesiophobia (TSK) values ​​according to the Hamada classification in patients who underwent reverse shoulder arthroplasty (RSA) for rotator cuff tear arthropathy (RCTA). METHODS: One hundred and eight patients who underwent RSA for RCTA were reviewed retrospectively. The patients were divided into two groups with low grade (stages 1-2-3) (n = 49) and high grade (stages 4a-4b-5) (n = 59) according to the Hamada classification, which is the radiographic evaluation of RCTA...

BACKGROUND: Individuals with shoulder pathologies frequently report sleep problems. Improving sleep quality is a treatment focus of shoulder arthroplasty. So far, it is unclear whether altered anatomy and biomechanics in reversed total shoulder arthroplasty affect sleep quality in the long term. In addition to a subjective evaluation, a reliable assessment can be obtained by recording objective sleep parameters. With the help of actigraphy, body movements are registered and divided into active and inactive phases by means of threshold values...

In trauma settings, including the management of outcomes, there is no consensus on the most appropriate reconstructive method in the presence of severe bone loss of the proximal humerus. The objective of this report is to evaluate the short-term functional outcomes of two patients in whom reverse shoulder megaprosthesis was used to treat the failure of trauma surgery with severe bone loss. The secondary objective was to compare the results obtained with the literature regarding the use of megaprosthesis in shoulder trauma surgery...
