Abstract
The aim of this study was to evaluate the security and effectiveness of AO/ASIF clavicle hook plate in the treatment of distal clavicle fractures and acromioclavicular joint dislocations. One hundred patients with distal clavicle fractures and acromioclavicular joint dislocations who were admitted in our hospital from January 2012 to January 2013 were selected as the study subjects. They were then randomly divided into a control group and an observation group (n=50). The observation group was treated with AO/ASIF clavicle hook plates, and the control group was treated with Kirschner-wire tension bands. The outcomes were recorded and compared. The JOA scores of the two groups were similar before surgery (P>0.05). The two groups both had obviously increased JOA scores in the postoperative 6th and 12th weeks, and the score in the postoperative 12th week was higher. There were statistically significant intra-group differences (P<0.05). The postoperative 6th-week and 12th-week JOA scores of the observation group were (83.2±1.8) and (97.4±1.5) respectively, and those of the control group were (71.6±2.2) and (82.3±2.6) respectively, with statistically significant inter-group differences (P<0.05). Significantly more patients in the observation group (100%) were evaluated as excellent or good outcomes after fixation than those in the control group (60%). After removal of the surgical apparatus, the recurrence rates of bone fracture and joint dislocation in the observation group were significantly lower than those of the control group (P<0.05). AO/ASIF clavicle hook plate functioned more effectively than Kirschner-wire tension band in clinical treatment of distal clavicle fractures and acromioclavicular joint dislocations. The former protocol enjoyed small incisions, firm fixation and early shoulder mobility. Therefore, it is a safe and effective surgical method that is worthy of being widely applied in clinical practice.
Highlights
Distal clavicle fractures and acromioclavicular joint dislocations, as common shoulder injuries in clinical practice, are mostly induced by violence
The observation group was treated with AO/ASIF clavicle hook plates, and the control group was treated with Kirschner-wire tension bands
Distal clavicle fractures can be classified into three Neer types, while acromioclavicular joint dislocations can be classified into three Tossy types
Summary
Distal clavicle fractures and acromioclavicular joint dislocations, as common shoulder injuries in clinical practice, are mostly induced by violence. Ensuring satisfactory recovery and aesthetically pleasing appearance, the former treatment does not function well for the patients with distal clavicle fractures and acromioclavicular joint dislocations. Nowadays, such patients are mainly treated surgically with Kirschner-wire tension band, T-type anatomical plate and miniature external fixator. These methods are prone to inducing complications.[2]
