RYAN, P et al. Glenoid hypoplasia: A case series of ten shoulders. SA orthop. j. [online]. 2014, vol.13, n.4, pp. 43-49. ISSN 2309-8309.

The terms 'glenoid hypoplasia', 'glenoid dysplasia' and 'dentate glenoid' refer to an uncommon developmental abnormality of the lower glenoid and scapular neck. The presenting symptoms are variable depending on the age at presentation, and in many cases the diagnosis is made incidentally on X-ray. The exact incidence is unknown, but is estimated in cadaveric and MRI studies to be in the region of 14.3% to 35% depending on the ethnic population studied.12 Current orthopaedic literature consists of case reports and small case series, with some of the more recent papers focusing on the arthroplasty management and implications.3-5

Keywords : glenoid hypoplasia; glenoid dysplasia; dentate glenoid.
