Abstract
Introduction
Hypoplasia of the glenoid is a rare condition caused by incomplete ossification of the postero-inferior aspect of the developing glenoid. It may be isolated or associated with a more generalised condition. The clinical symptomatology is variable depending on the age at time of presentation.
Materials and Methods
We performed a retrospective chart review of patients who presented with shoulder complaints, and in whom a radiographic diagnosis of glenoid hypoplasia had been made. From January 2002 to December 2012, 8 patients (9 shoulders) with radiological signs of glenoid hypoplasia were identified. The mean age at presentation was 39 years (range 23 to 77) and the mean symptom duration was 12.5 months (range 1 to 48).
Results
The diagnoses encountered included: impingement with rotator cuff tendonitis (2 shoulders), rotator cuff dysfunction with biceps tendonitis (1 shoulder), a SLAP lesion (2 shoulders), calcific tendonitis (1 shoulder), a posterior labral tear (1shoulder), multidirectional instability (1 shoulder), and adhesive capsulitis (1 shoulder). Of these nine, six shoulders were managed non-operatively and three were managed surgically, all with satisfactory results. The mean follow-up period was 30 months (range 5 to 60) and the mean Oxford shoulder score was 46.7 (range 42 to 48)
Conclusion
We present a series of patients, who have been managed for a variety of shoulder pathologies, and in whom underlying glenoid hypoplasia has been diagnosed.
