ABSTRACT
BACKGROUND:Clavicular hook plates have been used widely to treat acromioclavicular dislocations in recent years. However, it remains controversial whether coracoclavicular ligament should be repaired during the surgery. OBJECTIVE:To study the clinical effect and MRI manifestations after treatment of type III and V acute acromioclavicular Rockwood dislocation with clavicular hook plate, and to discuss the necessity of repairing coracoclavicular ligament during the surgery. METHODS:A total of 44 patients with type III and V acute acromioclavicular Rockwood dislocations were treated with clavicular hook plates without repair of coracoclavicular ligaments, and underwent plate removal operations later. At 24 months after the second surgery, X-rays were taken to measure the width of coracoclavicular joints in both normal and affected limbs, Constant-Murley scores were calculated in both sides, and MR images were used to observe the healing of coracoclavicular ligaments. RESULTS AND CONCLUSION:39 patients (89%) were fol owed up for 36.9±3.1 months (range, 30 to 45 months). The mean duration for retaining clavicular hook plates was 12.9±3.1 months (range, 6 to 21 months). The mean width of coracoclavicular joints was 6.04±1.21 mm (range, 4.3 to 8.8 mm) in normal limb, while 5.09±1.18 mm (range, 3.4 to 7.8 mm) in affected side without significant difference (P>0.05). The mean Constant-Murley score was 98.9±1.2 (range, 96 to 100) in normal limb, while 96.7±3.4 (range, 90 to 100) in affected side without significant difference (P>0.05). MRI showed healing of the coracoclavicular ligaments and the presence of continuous scar tissue in 38 patients, excluding one patient with recurrence of acromioclavicular joint dislocation. The clinical effects after treatment of type III and V acute acromioclavicular Rockwood dislocation with clavicular hook plate are satisfactory, and it is unnecessary to repair coracoclavicular ligament during the surgery. MR images reveal scar healing of the coracoclavicular ligaments without operative repair.
