Shoulder stability depends on several factors, either anatomical or functional. Anatomical
factors can be further subclassified under soft tissue (shoulder capsule, glenoid rim …

Posterior glenohumeral instability (PGHI) is a commonly under-and misdiagnosed pathology
owing to its variety of clinical presentations. In order to facilitate diagnosis and treatment, the …

Background Lateralizing the glenosphere and decreasing the humeral neck-shaft angles
are implant design parameters that reduce the risk of scapular impingement. The effects of …

Background: Posterior glenohumeral instability is an increasingly recognized cause of
shoulder instability, but little is known about the incidence or effect of posterior glenoid bone …

Posterior shoulder instability (PSI) is less common than anterior shoulder instability,
accounting for 2–12% of total shoulder instability cases. However, a much higher frequency …

Posterior shoulder instability (PSI) is defined by dynamic, recurrent and symptomatic partial
or total loss of posterior joint contact. Anatomic risk factors comprise ligament hyperlaxity …

Recurrent posterior glenohumeral instability is an entity that demands a high clinical
suspicion and a detailed study for a correct approach and treatment. Its classification must …

Background: The risk of re-engagement of bipolar bone defects in posterior shoulder
instability has not yet been investigated. Hypothesis: Posterior glenoid defects can lead to …

Purpose Purpose of this study was to evaluate the mid‐to long‐term outcome after
conservatively treated first‐time posterior shoulder dislocations and to determine structural …

Background: Little scientific evidence regarding reverse Hill-Sachs lesions (RHSLs) in
posterior shoulder instability exists. Recently, standardized measurement methods of the …
