Operative management of acromioclavicular joint dislocations can be with plate or with coracoclavicular screw fixation. As the coracoclavicular screw fixation can be done without opening acromioclavicular joint, they preserve the acromioclavicular joint ligaments, providing early healing and low infection rates. It achieves sufficient stability providing early mobilization of the neighboring joints.
In this study we have tried to analyze the outcome in terms of time for healing, functional results and complications of acromioclavicular joint dislocations managed with coracoclavicular screw fixation.
Methods: 20 adult patients with acromioclavicular joint dislocatios were treated with coracoclavicular screw fixation. under brachial plexus block all the dislocations were fixed using a vertical incision at lateral 1/3rd of clavicle under image intensifier assistance using a 4 mm cannulated cancellous screw across clavicle and coracoid. There were 15 males and 5 females with an average age of 35.75 years (21-60 years). All the patients were followed over a period of 2 years and results were analyzed.
Results: 17 (85%) dislocations healed within an average time of 8 weeks, in 3 (15%) dislocations screw back out occurred. Functional results were excellent in 16 (80%), moderate in 4 (20%) due to shoulder stiffness.
Conclusion: Coracoclavicular screw fixation offers a safe and reliable method of fixing acromioclavicular joint dislocations, with early healing. It provides early rehabilitation and reduces the hospital stay.
