Brief summary

studying coracoid tunnel widening after arthroscopic fixation of acute acromioclavicular joint (ACJ) dislocation using TightRope system and its correlation with loss of reduction and the functional scores.

Detailed description

Abstract Purpose: To detect coracoid tunnel widening after arthroscopic fixation of acute acromioclavicular joint (ACJ) dislocation using TightRope system and its correlation with loss of reduction and the functional scores. Methods: From July 2016 to Dec 2018, a prospective study was performed at our hospital. Twenty-three patients with acute grade III-V ACJ dislocation were included in the study. Arthroscopic double tight-rope repair of the ACJ was performed. Coracoid tunnel widening was measured by computed tomography (CT) and coraco-clavicular distance was measured on the x-ray immediately post-operative and at 12 months. Constant Shoulder Score, Oxford Shoulder Score, Nottingham Clavicle Score and Visual analogue scale were used as outcome measures at 12 months. Level of evidence IV Keywords Acute acromioclavicular joint injury . TightRope . Coracoid tunnel dilatation. Loss of reduction.

Design outcomes

Primary

Measure	Time frame	Description
Coracoid tunnel diameter difference between immediate postoperative and final follow up	1 year	Radiological outcome using CT scans
Coraco-clavicular distance immediate postoperative and at final follow up	1 year	Radiological outcome using X-rays

Secondary

Measure	Time frame	Description
Constant-Murley shoulder score. Ranges from 0 representing worst outcome to 100 representing best outcome	1 year	Clinical score using a questionnaire
Disability of arm shoulder and Hand score ( DASH score) highest is 100 which represents worst outcome while lowest is 0 representing best possible outcome	1 year	Clinical score using a questionnaire
Oxford Shoulder score, a questionnaire of 12 questions each scores from 1 to 5. 1 being the fewest symptoms, 5 being the worst. The total score is 60 marks, the higher the score the worse the outcomes	1 year	Clinical score using a questionnaire
