Glenoid loose

PURPOSE: This study aimed to evaluate age-stratified radiographic features in temporomandibular joint osteoarthritis using cone-beam computed tomography. MATERIALS AND METHODS: In total, 210 joints from 183 patients (144 females, 39 males, ranging from 12 to 88 years old with a mean age of 44.75±19.97 years) diagnosed with temporomandibular joint osteoarthritis were stratified by age. Mandibular condyle position and bony changes (flattening, erosion, osteophytes, subchondral sclerosis, and subchondral pseudocysts in both the condyle and articular eminence, thickening of the glenoid fossa, joint space narrowing, and joint loose bodies) were evaluated through cone-beam computed tomography...

BACKGROUND: Glenolabral articular disruption (GLAD) lesions may occur in adolescents with anterior shoulder instability, resulting in articular cartilage loss and reduced functional glenoid surface area. PURPOSE/HYPOTHESIS: To compare failure rates and patient-reported outcomes (PROs) between adolescents with versus without GLAD lesions who were treated for anterior shoulder instability with arthroscopic stabilization. It was hypothesized that the comparison would yield no significant differences...

BACKGROUND: Baseplate failure in reverse shoulder arthroplasty (RSA) is a rare but potentially catastrophic complication due to poor patient outcomes and significant glenoid bone loss. The purpose of this study was to report on prevalence, causes and outcomes of revision RSA for baseplate failure or loosening. METHODS: A retrospective review of our institutional database was performed to identify all patients treated for a failed RSA from 2006-2021 that required revision to another RSA (rRSA) by a single surgeon...

BACKGROUND: Total shoulder arthroplasty (TSA) can fail for several reasons, such as component loosening, periprosthetic fracture, instability, infection, soft tissue failure, or joint overstuffing. Severe metallosis without loose glenoid components after TSA may result in the need for revision to reverse TSA. CASE PRESENTATION: Four years before the current presentation, an 86-year-old woman suffered from right shoulder pain and swelling. The initial diagnosis was osteoarthritis of the shoulder joint, for which she underwent TSA...

BACKGROUND: The healing capacity of the human glenoid labrum varies by tear location. Current evidence suggests that the healing capacity of meniscal and cartilage injuries relates to cellular composition and vascularity. However, little is known about the histological characteristics of the glenoid labrum and how they may affect healing potential in specific anatomic regions. HYPOTHESIS: Regenerative characteristics of the glenoid labrum differ based on the anatomic region...

OBJECTIVE: The number of shoulder arthroplasties is increasing along with the need for revision surgeries. Determining the stability of the implant is crucial in preoperative planning. This study aims to investigate whether radiolucent lines (RLL) in preoperative radiographs predict component loosening. MATERIALS AND METHODS: Preoperative radiographs of 93 cases in 88 patients who underwent shoulder arthroplasty revision were evaluated regarding the presence of RLL...

BACKGROUND: Severe glenohumeral osteoarthritis (GHOA) with posterior glenoid erosion remains challenging to address for shoulder surgeons. Whereas anatomic total shoulder arthroplasty (TSA) has historically been the treatment of choice, reverse shoulder arthroplasty (RSA) offers an alternative option. Limited evidence exists directly comparing these 2 treatments in a similar patient population. The purpose of this study was to compare the clinical outcomes of patients with GHOA and Walch type B2 and B3 glenoid morphologies treated with TSA vs...

A spectrum of pathologies can cause clicking, popping or snapping of the shoulder joint. These can lead to a patient seeking attention in clinical practice due to pain, discomfort and impact on activities of daily living. Traditionally these can originate from pathologies which involve biceps tendon, tears of the rotator cuff or the glenoid labrum, articular cartilage or due to loose bodies and scapulothoracic joint dysfunction [Guillin et al. in Br J Radiol 85:1343-1353, 2012; Vidoni et al. in Indian J Musculoskelet Radiol 4:61-69, 2022]...

PURPOSE: The purpose of this study is to report the outcomes of the all-arthroscopic Trillat procedure, combined with capsular plication, for the treatment of recurrent anterior instability in young athletes with shoulder hyperlaxity (ER> 90°). METHODS: We performed a retrospective evaluation of patients with recurrent anterior instability and shoulder hyperlaxity who underwent an arthroscopic Trillat between 2009 and 2019. Patients with concomitant rotator cuff lesions, voluntary or multidirectional instability were excluded...

BACKGROUND: While there is a trend to manage failed anatomic total shoulder arthroplasties (aTSA) with revision to a reverse total shoulder arthroplasty, such revisions can be complicated by difficulties in baseplate fixation, instability, and acromial stress fractures. Some cases of failed aTSA may be safely revised to a hemiarthroplasty (HA). The objectives of this study were to report patient-reported outcomes after conversion from aTSA to HA and assess patient and shoulder characteristics associated with a successful outcome...

BACKGROUND: Total shoulder arthroplasty provides excellent long-term clinical outcomes in the treatment of glenohumeral arthritis. However, symptomatic glenoid polyethylene loosening can be seen at intermediate follow-up and can lead to shoulder pain and dysfunction. The purpose of this study was to perform a systematic review of the available literature to determine the optimal management of symptomatic glenoid loosening with regards to reoperation and patient satisfaction following various approaches to symptomatic glenoid loosening...

OBJECTIVE: To investigate the diagnosis and treatment procedure of synovial chondromatosis (SC) of the temporomandibular joint (TMJ). METHODS: Clinical features, imaging features, surgical methods, and prognosis of 7 patients with SC of the TMJ were analyzed. We also reviewed and analyzed surgery-relevant literature included in the Pubmed database in the past decade using the search terms "synovial chondromatosis" and "temporomandibular joint", and found 181 cases...

Glenohumeral arthritis is a challenging problem, especially in the young, active patient. After nonoperative treatment, including activity modification, anti-inflammatory medications, physical therapy, and injections, is exhausted, surgical treatment ranging from simple debridement to arthroplasty is commonly offered. Given concerns regarding arthroplasty implant longevity, there is an interest in joint-preserving procedures. In this difficult population, the authors recommend a systematic, inclusive approach to the array of pathologies encountered in the setting of early glenohumeral arthritis: the Comprehensive Arthroscopic Management (CAM) procedure...

BACKGROUND: Glenoid bone loss is one of the main challenges in revision of failed shoulder arthroplasties. The concept of a hemi-reverse procedure is to implant a glenoid baseplate and glenosphere to protect the glenoid reconstruction to allow it to heal and to preserve the joint space for a potential second-stage humeral component implantation. The purpose of this study was to report the results of hemi-reverse procedures. METHODS: Revision to a hemi-reverse procedure was performed in 15 patients: 8 with a failed anatomic total shoulder arthroplasty, 3 with a failed reverse shoulder arthroplasty, 3 with a failed humeral hemiarthroplasty, and 1 with placement of a cement spacer owing to sepsis after a total shoulder arthroplasty...

BACKGROUND: Hybrid glenoid component fixation represents an emerging technology in total shoulder arthroplasty (TSA) design. However, there is a paucity of larger-scale studies reporting the outcomes following implantation of these components. This study aimed to determine the outcomes following primary TSA using hybrid glenoid component fixation with a central porous titanium post. METHODS: A retrospective review of 2 institutional databases identified patients aged ≥ 18 years who underwent primary elective hybrid TSA between 2009 and 2018 with a minimum of 2 years of follow-up...

AIMS: The use and variety of stemless humeral components in anatomical total shoulder arthroplasty (TSA) have proliferated since their advent in 2004. Early outcomes are reassuring but independent mid-term results are scarce. This independent study reports a consecutive series of 143 Eclipse stemless shoulder prostheses with a minimum five-year (5 to 10) follow-up. METHODS: Outcomes of 143 procedures undertaken for all indications in 131 patients were reviewed, with subset analysis of those for osteoarthritis (OA) (n = 99)...

RATIONALE: Synovial chondromatosis of the shoulder joint is uncommon; this condition usually affects the knee joint and the hip joint. Lesions of multiple chondral nodules form in the synovium and are usually found within the joint capsule. Treatment of synovial chondromatosis consists of loose body removal and synovectomy. In synovial chondromatosis of the shoulder, arthroscopic loose body removal and synovectomy have been reported with good outcomes. Arthroplasty can be a treatment option when osteoarthritis co-occurs at the affected joint...

BACKGROUND: Few studies have compared clinical outcomes between the traditional Latarjet procedure for anterior shoulder instability and the congruent arc modification to the Latarjet procedure. PURPOSE: To systematically evaluate the literature for the incidence of recurrent instability, clinical outcomes, radiographic findings, and complications for the traditional Latarjet procedure and the congruent arc modification and to compare results of each search. STUDY DESIGN: Systematic review; Level of evidence, 4...

Background: Shoulder microinstability is often overlooked, which can be problematic, especially in overhead athletes. The slipping phenomenon is defined as posterior or lateral sliding of the humeral head in an elevated arm. When the shoulder is close to the end range of stability, the infraspinatus is highly activated and keeps the shoulder in the glenoid cavity. This study aimed to examine the characteristic physical function and infraspinatus activity during the pitching motion in baseball pitchers with shoulder instability...

Background: Coracoid transfer procedures have been increasingly utilized for anterior shoulder instability with associated glenoid bone loss1 . Unfortunately, in a young, high-risk patient population, these procedures can fail secondary to traumatic causes but also because of bone graft resorption or malposition or hardware prominence, among other reasons2 . In active patients, revision glenoid reconstruction may be indicated. Distal tibial osteoarticular allografts have been utilized to treat recurrent anterior shoulder instability for several years3 ...
