Association between risk factor for anteriror glenohumeral instability and bone loss in active sport players

Svetoslav Dobrilov, Maxim Zagorov, Kalin Mihov


Introduction: Practicing mass and professional sport is with growing popularity among   young people. Sports like football, basketball, volleyball, and contact disciplines - boxing, martial arts, etc. are highly connected to trauma. Shoulder dislocation is very frequent and in most cases turns into instability. The main cause for it is glenoid and/or humeral bone loss.

Material and methods: For the period 2010-2015 in University Hospital `St. Marina` 22 patients with high physical activity were operated - 5 of them are professional sportsmen. Volume of bone lose is measured with CT and the method proposed by Sugaya. Indications for operative treatment were based on history, clinical examination, imaging and ISIS score. The performed operative treatment was coracoid transfer over glenoid rim. 

Results: All patients had significant for instability bone loss. The postoperative period was smooth and there were no instability recurrences detected during the follow-up period.

Conclusions: Glenohumeral instability in sportsmen is a result of recurrent shoulder dislocations, main cause for which is glenoid and/or humeral bone loss. Detecting and measuring the level of this bone loss is of great importance for the correct treatment algorithm leading to joint stability and return to active and competitive sport activities.
