BACKGROUND: Loosening of the glenoid component is a primary reason for failure of an anatomic shoulder arthroplasty. Pegged glenoids were designed in an effort to outperform keeled components. This study evaluated the midterm clinical and radiographic survival of a single implant design with implantation of an in-line pegged glenoid component and identified risk factors for radiographic loosening and clinical failure. MATERIALS AND METHODS: There were 330 total shoulder arthroplasties that had been implanted with a cemented, all-polyethylene, in-line pegged glenoid component evaluated with an average clinical follow-up of 7...

BACKGROUND: Glenoid component loosening is a common indication for revision shoulder arthroplasty. The objective of this study is to assess the longer-term outcomes of patients undergoing revision specifically for aseptic loosening. MATERIALS AND METHODS: Between 1985 and 2005, 34 revision shoulder arthroplasties were performed for aseptic glenoid loosening. Three patients were lost to follow-up. Treatment included component reimplantation in 20 shoulders (group I) or component removal with bone grafting in 11 shoulders (group II)...

INTRODUCTION: The glenoid labrum is frequently torn in traumatic glenohumeral dislocation; arthroscopic repair is the standard method of treatment. The complications associated with this repair are pulling out of metal suture anchors, chondrolysis and joint infection. The infection of joint after arthroscopy is less than 1%. Staphylococcus is most common organism and rarely followed by Pseudomonas aeruginosa. We report a case of infected shoulder with chondrolysis of the joint and pulled out metal suture anchor lying inside the joint after Bankart's repair...

BACKGROUND: MRI is the standard methodology in diagnosis of rotator cuff diseases. However, many patients continue to have pain despite treatment, and MRI of a static unloaded shoulder seems insufficient for best diagnosis and treatment. This study evaluated if Dynamic MRI provides novel kinematic data that can be used to improve the understanding, diagnosis and best treatment of rotator cuff diseases. METHODS: Dynamic MRI provided real-time 3D image series and was used to measure changes in the width of subacromial space, superior-inferior translation and anterior-posterior translation of the humeral head relative to the glenoid during active abduction...

BACKGROUND: Large glenoid defects pose difficulties in shoulder arthroplasty. Structural grafts consisting of a humeral head autograft, iliac crest, and allograft have been described. Few series describe grafts used with reverse total shoulder arthroplasty (RTSA). METHODS: We retrospectively reviewed patients who had undergone primary or revision RTSA. We identified 44 patients (20 men and 24 women; mean age, 69 years) as having a bulk structural graft to the glenoid behind the baseplate...

BACKGROUND: Glenoid loosening is one of the most common causes of total shoulder failure. High rates of positive cultures of Propionibacterium and coagulase-negative staphylococcus have been found among shoulders having surgical revision for glenoid loosening. This study reviewed the culture results in a series of surgical revisions for failed total shoulder arthroplasty to determine the relationship between glenoid loosening and positive cultures. METHODS: The medical records of 221 patients without obvious evidence of infection who underwent revision total shoulder arthroplasty were reviewed to examine the association between the security of fixation of the glenoid component and the results of cultures obtained at revision surgery...

INTRODUCTION: Osteoarthritis of the shoulder often results in significant posterior glenoid wear. The options for treating this have been eccentric glenoid reaming and occasionally bone grafting. More recently reverse total shoulder arthroplasty (rTSA) with or without bone grafting and posterior augmented glenoids (PAGs) has been introduced. The PAG restores the native joint line while reaming a minimal amount of glenoid bone. The purpose of this study is to compare osteoarthritic shoulders with significant posterior glenoid wear treated with anatomic total shoulder arthroplasty (aTSA) using a PAG to shoulders without glenoid wear treated with aTSA using a standard all poly pegged glenoid...

Loosening of the glenoid component is a frequent cause of failure of total shoulder arthroplasty (TSA). The etiology of glenoid component loosening is multifactorial and includes aseptic osteolysis, rotator cuff insufficiency, soft tissue instability, and infection. A loose glenoid component is frequently associated with a substantial loss of glenoid bone, which necessitates additional procedures to implant a new component. Several studies have shown that patients with a new glenoid component have better clinical outcomes, which makes successful glenoid reimplantation a priority...

In France, the number of revisions for total shoulder arthroplasty (TSA) has increased by 29% between 2006 and 2010. Published studies have reported a revision rate of approximately 11% for hemi-arthroplasty and total anatomical implants, and 10% for reversed implants. The decision to revise or not revise a TSA requires that a rigorous, clinical, laboratory and imaging initial assessment be done in order to answer five questions. Is it infected? Is it unstable? Is it worn? Is it loosened? How is the rotator cuff? This assessment and an evaluation of the bone stock are required to decide whether or not to revise...

The purpose of the study was to describe the normal anatomy of the glenoid labrum to help identification of pathology and guide surgical repair. Twenty dry bone scapulae and 19 cadaveric shoulders were examined. Light microscopy was performed on 12 radial slices through the glenoid. An external capsular circumferential ridge, 7-8 mm medial to the glenoid rim marks the attachment of the capsule. A separate internal labral circumferential ridge 4 mm central to the glenoid rim marks the interface between the labrum and articular cartilage...

The clinical results obtained an average of 4.2 years after resurfacing of the humeral head in 72 rheumatoid shoulders showed 94% of the patients being pleased regarding pain relief and 82% reporting improved shoulder mobility. Shoulder function was significantly improved. The radiographs were analyzed regarding the position of the humeral head resurfacing cup, proximal migration of the humerus, and glenoid attrition during the follow-up period. Change of the distance between the superior margin of the cup and the greater tuberosity and/or change of inclination of the prosthesis were regarded as signs of prosthetic loosening...

BACKGROUND: The reverse total shoulder replacement has become a popular treatment option for cuff tear arthropathy and other shoulder conditions requiring arthroplasty in the setting of a deficient rotator cuff. Despite a revision rate of as much as 10%, to date, there are few reports of reverse replacement conversion to hemiarthroplasty, and none specifically examining shoulder function. MATERIALS AND METHODS: Six patients with a reverse replacement that was dislocated, infected or loose were revised an average of 9...

Since synovial chondromatosis (SC) clinically mimics symptoms of internal derangements of the TMJ, the diagnostic value of MRI and CT, overlooked for years, is discussed in the presented case. Multiple amorphous calcifications in the left infratemporal fossa and upper synovial compartment of the TMJ were detected on the CT and MRI scans. The patient underwent open TMJ arthrotomy and removal of 15 calcified loose bodies. SC may be diagnosed radiographically when sclerosis of the glenoid fossa, soft tissue edema, and intraarticular radio-opaque loose bodies are detected...

Post-operative change in the mechanical loading of bone may trigger its (mechanically induced) adaptation and hamper the mechanical stability of prostheses. This is especially important in cementless components, where the final fixation is achieved by the bone itself. The aim of this study is, first, to gain insight into the bone remodelling process around a cementless glenoid component, and second, to compare the possible bone adaptation when the implant is assumed to be fully bonded (best case scenario) or completely loose (worst case scenario)...
