Morphological classification of acromial spur: correlation between Rockwood tilt view and arthroscopic finding

چکیده
Purpose and hypothesis: Acromion spur is the extrinsic factor for impingement syndrome and rotator cuff tear. The Rockwood tilt view can be used to evaluate prominence of the anterior acromion, however no study has shown the correlation of findings between the Rockwood tilt view and the arthroscopic finding. METHODS We developed the arthroscopic classification of acromion spur as type 1 flat spur, type 2 bump spur, type 3 heel spur, type 4 keel spur, and type 5 irregular spur. Patients with rotator cuff syndrome who underwent arthroscopic surgery were recruited. Two observers were asked to classify the type of spur from arthroscopic findings and Rockwood tilt views separately in random pattern. The prevalence of supraspinatus tendon tear was also recorded as no tear, partial-thickness tear, and full-thickness tear. RESULTS The keel spur (33.9%) was the most common finding followed by the heel spur (27.8%). The correlation was high especially for the heel, the keel, and the irregular spur (75.47%, 74.03%, and 72.73%, respectively.) These three types of spurs have a high prevalence of full thickness of supraspinatus tendon tear. CONCLUSION The Rockwood tilt view can be used to evaluate the morphology of an acromion spur, especially the at-risk spur that correlates highly with the full-thickness supraspinatus tendon tear. The arthroscopic classification will also be a useful tool to improve communication between the surgeon and the guide for appropriate treatment in a rotator cuff tear patient when encountering the heel, keel, and irregular spur.

OBJECTIVE The objective of the present study was to determine the acromial shape and examine if there is a correlation between the acromial morphology and genders, ages and sides. MATERIAL AND METHOD The present examined 154 dried Thai scapulas (107 males and 47 females) with age range from 16 to 87years (mean = 49 + 17 years). The acromial morphology of each scapula was studied by the comput...
متن کاملCorrelation of acromial morphology with impingement syndrome and rotator cuff tears
BACKGROUND AND PURPOSE Indications for acromioplasty are based on clinical symptoms and are generally supported by typical changes in acromial morphology on standard radiographs. We evaluated 5 commonly used radiographic parameters of acromial morphology and assessed the association between different radiographic characteristics on the one hand and subacromial impingement or rotator cuff tears ...

The influence of individual acromial morphology on the pathogenesis of rotator cuff tears remains controversial. Since Neer first described the impingement syndrome, several authors have described the morphology of the acromion. In this study, we try to find a physiopathological correlation between the anatomical morphology of the acromion based on these two recently descripted parameters (Acro...
