Allogeneic tendon graft for reconstruction of the coracoclavicular and acromioclavicular ligaments in acromioclavicular dislocation

Objective To introduce and evaluate a new reconstructive method for the coracoclavicular and acromioclavicular ligaments using allogeneic tendon graft in the management acromioclavicular joint dislocation.Methods Between February 2010 and February 2012,6 cases of acromioclavicular joint dislocations were treated with allogeneic tendon graft to reconstruct the V structure of coracoclavicular and acromioclavicular ligaments in our clinic.Patient satisfaction,appearance of the shoulder,shoulder range of motion,maintenance of the reduced acromioclavicular joint in X-rays,Constant-Murley shoulder scores,UCLA shoulder scores and VAS for pain were documented during follow-up evaluation.Results The patients were available for a mean follow-up of 18 months (range,8 to 25 months).Patient satisfaction was documented as 83.3％.All patients had a normal appearance of the shoulder.Flexion and abduction of the shoulder were 163.5° and 147.2° respectively.The mean Constant-Murley and UCLA shoulder scores were 95.3 and 32.8 respectively.The mean V AS score of the patients was 0.3.Conclusion Reconstruction of the coracoclavicular and acromioclavicular ligaments with allogeneic tendon graft can achieve good outcomes in treatment of acromioclavicular joint dislocation.It fulfills biomechanical requirements and maintains sustainable and stable reduction of the joint.
