Abstract Introduction:
It is estimated that between 15 and 50 people per 100,000 suffer from a collagen disease or connective tissue disorder. Very frequently, the inherent hypermobility disturbs shoulder, ankle, and patellofemoral mechanics. In the shoulder, multidirectional instability (MDI) is the typical result.
The treatment recommendations for symptomatic MDI in patients with a systemic collagen disorder are fairly controversial. A better understanding of the "normal" shoulder function in this population would help in developing effective and evidence-based treatment protocols.

250 patients with genetic hypermobility or Ehlers-Danlos Syndrom were surveyed for their day-to-day shoulder function. Endpoints were subjective shoulder function (SSV), the ROWE and WOSI scores, demographic details and a free text question.

The return rate for the questionnaire was 93%. Most patients (56%) were between 22 and 40 years of age, female (86%), suffering from EDS (70%). 84% are suffering from constant joint pain, with a median Tegner activity score of 8. Shoulder pain is bilateral in 64%, 74% have experienced more than 6 full dislocations.
72% do sports on a regular basis. The mean SSV was 73 ± 23%. The mean Rowe score was 46 ± 22 pts, the mean WOSI score 59 ± 21 pts.
Three issues stood out in the free text response: pain and instability are independent problems; scapular problems often more troublesome than the glenohumeral instability; neurological issues even after successful stabilization.

In this population with genetic hypermobility, there was an interesting discrepancy between low clinical scores, but high levels of sports participation and SSV, suggesting well functioning compensation mechanisms. Many patients perceive their scapular problems equally or even more troublesome than the acutal glenohumeral instability.
