Abstract:

BACKGROUND: Surgical therapy has been frequently used to treat Rockwood type Ⅲ acromioclavicular joint dislocation to restore normal anatomy of stable structures around the acromioclavicular joint and heal free of tension.
OBJECTIVE: To investigate the clinical effect of clavicular hook plate implantation on Rockwood type Ⅲ acromioclavicular joint dislocation.
METHODS: A total of 56 patients with Rockwood type Ⅲ acromioclavicular joint dislocation were selected from Department of Orthopedics of Wufeng People’s Hospifal and Department of Orthopedics of Yiling Hospital between December 2005 and June 2008. All patients were treated with clavicular hook plate implantation. Indicators including visual analogue scale (VAS), the United States Shoulder and Elbow Surgeon Score (ASES), and Constant and Murley scoring system were tested pre-operatively, one year postoperatively, before internal fixation, and 3 months after internal fixation. Additionally, functional changes of the shoulder joint and complications were analyzed before and after clavicular hook plate implantation.
RESULTS AND CONCLUSION: The surgery and follow-up were successfully achieved in 56 cases. The follow-up lasted for 15-30 months, with the mean time of 20 months. The internal fixation was taken out at about 1 year after implantation. Coracoclavicular ligament was repaired in 32 cases but not in 24 cases. Two patients with recurrence of acromioclavicular joint dislocation were excluded, and coracoclavicular ligament therapy was not performed. Shoulder pain, foreign body sensation, and internal fixation failure occurred in two cases. One year after operation, VAS was decreased compared with that before operation, but ASES and Constant and Murley score were significantly increased (P < 0.01). At 3 months after internal fixation, VAS was decreased compared with that at 1 year after operation, but ASES and Constant and Murley score were increased (P < 0.05). Results demonstrated that clavicular hook plate implantation for treating Rockwood type Ⅲ acromioclavicular joint dislocation is simple and minimally invasive, thus it is an ideal internal fixation.
