Functional and radiological outcomes of acromioclavicular joint reconstruction in type iii disruption without allograft with synthetic materials

Abstract

Introduction: Effectiveness of surgery for complete Acromio-clavicular Joint (ACJ) dislocation is controversial. We analyzed the long-term Functional and radiological outcome after in on Acromio-clavicular ligament reconstruction by modified Mazzocca technique for Type 3 dislocations. Aim: To study the functional and radiological outcomes of acromioclavicular joint reconstruction in type III disruption without allograft with synthetic materials Method: Retrospective analysis of case records and patient reviewed to assess the long-term functional and radiological outcome by patient satisfaction, UCLA shoulder rating score and coracoclavicular distances. Results: We had 38 cases of Type 3 Acromio-clavicular dislocations over a period of 5 years. Mean age of the entire group was 42.1 years (26 to 57). Among them, 32 are males and six females. Three patients were lost their follow-up during the post-op rehabilitation period; among them, two were presented with infection, one with shoulder stiffness. Long-term functional and radiological outcomes were regarding UCLA shoulder rating score, patient satisfaction and coracoclavicular distances compared with the uninjured shoulder. Conclusions: More aggressive management of acromioclavicular dislocation needed to avoid poor results with chronic injuries, and we have moved toward without graft and earlier surgical intervention. We recommend modified Mazzocca technique used in the management of Grade 3 Acromio-clavicular joint dislocation for the following reasons (A). Better short-term functional and radiological outcome and low risk of complications (B). No need graft harvesting surgery and decreased donor site morbidity.
