BACKGROUND Posterior glenoid bone loss is commonly encountered in total shoulder arthroplasty (TSA). The purpose of our study is to report the clinical and radiographic findings of patients with a minimum of 2 years' follow-up treated with an all-polyethylene, augmented glenoid component. METHODS Twenty-two shoulders with posterior glenoid bone loss were treated by a single surgeon. All under...

We have undertaken a prospective clinical and radiological analysis of 124 shoulder arthroplasties (113 patients) carried out for osteoarthritis. The clinical results showed improvement in the absolute Constant score and the American Shoulder and Elbow Surgeons score of 22 and 43, respectively. Both were statistically significant (p < 0.001). There was no significant difference in the scores af...

BACKGROUND Successful placement of a fixation device on the superior glenoid rim during superior labrum repairs requires accurate knowledge of the glenoid rim anatomy. PURPOSE To investigate the normal bony anatomy of the superior glenoid rim. STUDY DESIGN Descriptive anatomic study. METHODS Twenty cadaveric glenoid specimens were scanned to obtain cross-sectional images with peripheral q...

BACKGROUND A variety of measurements can be used to assess radiographic osteoarthritic changes of the shoulder. This study aimed to analyze the correlation between the radiographic humeral-sided Samilson and Prieto classification system and 3 different radiographic classifications describing the changes of the glenoid in the coronal plane. METHODS The study material included standardized radi...

In 100 patients the fulcrum axis which is the line connecting the anterior tip of the coracoid and the posterolateral angle of the acromion, was used to position true anteroposterior radiographs of the shoulder. This method was then compared with the conventional radiological technique in a further 100 patients. Three orthopaedic surgeons counted the number of images without overlap between the...

BACKGROUND Despite an increased awareness of the condition, the diagnosis, classification, and treatment of recurrent posterior shoulder instability remain challenging. No clear relationship has been established between glenohumeral morphologic characteristics and the risk for posterior shoulder instability or with outcomes after treatment. PURPOSE To examine the structure of the glenoid in a...

Subchondral bone cysts (subchondral cystic lesions or osseous cyst-like lesions) are relatively uncommon in the horse (Baxter 1996). They may be articular or extra-articular, and may, or may not, result in lameness (Baxter 1996), although most cystic lesions that contribute to lameness are articular in nature (Bramlage 1993). Horses from all breeds are susceptible, and whilst the disease has be...

Shoulder instability after a posterior glenoid rim fracture is rare and potentially difficult pathology to treat. Operative techniques often involve a large dissection to view the fragments resulting in local soft tissue injury. Internal fixation is often achieved with interfragmentary screws; however, this may not be possible with small or multifragmentary fracture patterns. We describe an art...

We performed an RSA (Anatomical Shoulder (TM) Inverse/Reverse; Zimmer) on a 73-year-old, right-handed man who had radiographic evidence of an irreparable rotator cuff tear and early rotator cuff arthropathy. The patient was immobilized in a sling for 6 weeks postoperatively. The sling was removed 3 times daily for shoulder exercises. At 4 weeks postoperatively, the patient reported good pain re...
