Background: Managing posterior glenoid wear and retroversion remains a challenge in shoulder arthroplasty.Correcting glenoid version through asymmetric reaming (AR) with placement of a standard glenoid component and theuse of posteriorly augmented glenoid (PAG) components are two methods used to address this problem. Our objectiveis to report the radiographic outcomes of patie...

Glenohumeral osteoarthritis is the most common reason for shoulder replacement. Total shoulder arthroplasty provides reliable pain relief and restoration of function, with implant survivorship reported at 85% at 15 years. Glenoid component wear and aseptic loosening are among the most common reasons for revision. Glenoid wear characteristics have been correlated with, among other things, the de...

BACKGROUND Modern cementing techniques have improved glenoid fixation, reduced glenoid lucency seen with keeled components, and may eliminate differences attributable to glenoid design. The purpose of this study was to determine the effect of glenoid design on immediate and follow-up radiographic lucency of pegged and keeled glenoid components, using modern cementing techniques. MATERIAL AND ...

Condyle dislocation is defined as displacement of the condyle out of the glenoid fossa while it still remains within the joint capsule [1]. The condyle can be dislocated in many directions, with antero-medial and anterior dislocation being the most common [2-4]. On the contrary, dislocation of an intact condyle into the middle cranial fossa is very rare [24,6]. In general the condyle has a larg...

BACKGROUND Total shoulder arthroplasty is technically demanding in regard to implantation of the glenoid component, especially in the setting of increased glenoid deformity and posterior glenoid wear. Augmented glenoid implants are an important and innovative option; however, there is little evidence accessible to surgeons to guide in the selection of the appropriate size augmented glenoid. M...

A forty-one-year-old male patient was referred to our department of Radiology for left shoulder pain and reduced mobility. There was no history of trauma, infection nor therapeutic intervention. A plain radiograph (Fig. A) of the left shoulder showed the presence of two small roundshaped lucent bubbles in the soft tissue above the glenoid. An additional ultrasound examination revealed the prese...

  Background : Glenoid bone damages consisting of anterior rim erosion and bony avulsion are very important in decision making for treatment of recurrent dislocation in shoulder joint. This study was aimed to determine the prevalence of these damages in patients with anterior recurrent shoulder dislocation.   Methods : The study was a cross-sectional study evaluating patients with unstable shou...

BACKGROUND The conventional measuring method for glenoid version is greatly influenced by the scapular body shape that varies widely between patients. We postulated that the glenoid vault version could be more useful than the conventional glenoid version in clinical cases. OBJECTIVES The purposes of this study were to compare the values of glenoid version measured with the conventional method...

HYPOTHESIS The success of shoulder arthroplasty surgery has been limited by a common complication: glenoid implant loosening. Eccentric loading of the glenoid due to migration of the humeral head is considered to be the major cause of glenoid loosening and is referred to as the rocking-horse phenomenon. Glenoid implant loosening may cause pain, limitation of function, and the need for complicat...
