Abstract
Rotator cuff disease has been recognized for over 100 years. Full
thickness tears of rotator cuff are among the most frequently encountered
causes of pain and dysfunction in the shoulder. Since shoulder complaints are
the third most frequent cause (after knee and spine) of musculoskeletal
symptoms in the community, rotator cuff disease represents a significant
health economic issue. Cadaver studies in the elderly estimate the prevalence
of full thickness tears to be from 5% to 30%. MRI and ultrasound studies
have demonstrated that the prevalence of asymptomatic full thickness tears is
from 15% to 23% overall, 4% to 13% in subjects under the age of 59 years
and 28% to 51% in subjects between 60 and 80 years of age.
With recent advances in shoulder arthroscopy, techniques for
performing a successful rotator cuff repair have evolved from full open
procedures to arthroscopically assisted mini-open techniques to an allarthroscopic
technique.
In our study we hypothesized that, there is a critical period in which
degenerative and traumatic rotator cuff tears should be repaired to allow for
improvement of the functional outcome.
This is a prospective study conducted upon attendants of orthopedics
outpatient clinics of Suez Canal University Hospital in Ismailia city and
Fayoum University hospital in Fayoum city starting from January 2009 till
December 2011. This study included 31 cases; (16) cases of which were
done at Suez Canal University hospitals and (15) cases were done at Fayoum
University hospitals.
