PREVALENCE OF PARTIAL THICKNESS ROTATOR CUFF TEAR IN YOUNGER POPULATION (20 - 40 YEARS)- A CADAVERIC STUDY
Journal Title: Journal of Evolution of Medical and Dental Sciences - Year 2018, Vol 7, Issue 19
Abstract
BACKGROUND Most of the rotator cuff injuries are left unnoticed in the early period, because of lack of knowledge and evidence of its prevalence and later on they present in an inoperable state at younger age. There is a discrepancy between cadaver and clinical studies because intratendinous tears are more difficult to diagnose with arthroscopy, MRI or ultrasound than bursal or articular tears. MATERIALS AND METHODS We performed a cadaveric study in the Department of Orthopaedics, Madurai Medical College. Rotator cuff muscles (Supraspinatus and infraspinatus) were dissected from fresh cadavers of both sexes on both sides, excluding those with soft tissue or bony injuries regardless of the cause of death. 75 rotator cuff specimens, dissected from 40 cadavers in Mortuary, Government Rajaji Hospitals under guidance of Forensic Medicine Department, Madurai Medical College with age at death between 20 and 40 years (mean age29.22 years) were analysed for the prevalence of macroscopic and microscopic partial thickness tear (PTT) and in occupation requiring overhead activities. RESULTS In our study, overall prevalence of PTT in young cadaveric population (20 - 40 years) was found to be 10%. Bursal sided PTT (7.5%) are more common than articular (2.5%). All 4 subjects had tear bilaterally (100%). CONCLUSION The lower prevalence of PTT in younger age group suggests an age-related degeneration in the pathogenesis of rotator cuff tear. As there is a strong evidence of bilateral presence, it is important to screen asymptomatic contralateral shoulder in patients with RCT.
