Assesment of Functional Outcome of Acromio Clavicular Joint Injuries Treated By Hook Plate Using Penn and Constant Score
Journal Title: IOSR Journal of Dental and Medical Sciences (IOSR-JDMS) - Year 2018, Vol 17, Issue 8
Abstract
Introduction Acromioclavicular joint dislocation is very common following upper extremity trauma. For acromioclavicular joint dislocations that are Rookwood type III and above, surgical treatment is currently recommended. Aims & Objectives: To Analyze the functional outcome of Acromioclavicular joint injuries (dislocations) grade 3 to 6 which were treated surgically using a hook plate. Material & Methods: A retrospective analysis was performed on the patients treated with a hook plate for Acromioclavicular joint dislocation in our hospital from February 2011 to March 2014 There were total 30 cases of pure acromioclavicular joint dislocation without associated injuries, including 21 males, and 9 females; mean age was 48.27 + 8.7 years (age range 20-67 years old). There were 28 cases of Rockwood type III acromioclavicular dislocation, 2 cases of type V. 16 cases had the injuries on the left side, 14 cases on the right side. All patients had open reduction and hook plate fixation within 2 to 6 days after injury, and had the hook plate removed within 8 to 12 months after the surgery. Results: According to the Constant-shoulder score the average scores were 76 ± 6 points 8 to 12 months after the surgery and before the removal of the hook plate, the average scores were 88 ± 6 minutes two months after the removal of hook plate. Postoperative X-ray imaging showed osteolysis in 9 cases (33.3%), osteoarthritis in five cases (20.%), osteolysis associated with osteoarthritis in four cases (13.3%), and steel hook broken in one case (3%) PENN score was excellent in 26 patients, good in 2 and fair in 2 cases patients. Conclusion: The use of hook plate on open reduction and internal fixation of the acromioclavicular joint dislocation had little adverse effect on shoulder function and is an effective method for the treatment of acromioclavicular joint dislocation. Osteoarthritis and osteolysis are the two common complications after hook plate use, which are associated with the impairment of shoulder function. Shoulder function will be improved after removal of the hook plate.
