“Study on functional outcome of reconstruction of acromioclavicular joint dislocations type III to type VI using tight rope with endobutton”

Abstract

Introduction: Acromioclavicular joint are common in physical active young adults, mostly involves in sports activities. Its male predominant and account 9% of all shoulder injuries. Tight rope and endobutton reduces the chances of clavicular fracture across the tunnels and avoids hardware related complications. Aims and Objectives: To study functional outcome of acromioclavicular joint dislocat ion by using tight rope and endobutton. Materials and methods: This is prospective study of 25 cases of AC joint dislocations type iii to vi admitted between oct 2017 to march 2019. Out of 25 only 16 patients was operated.In procedure, clavical tunnel made, tight rope passed around coronoid process and through clavicular tunnel and secure with endobutton. Observations and Results: In our study M:F of 17:8 and mean age of 44 years having right side predominance, average blood loss 150 ml functional outcome by CONSTANT score got 4 complications. 8 patients got excellent result, 6 good, 2 adequate results. Conclusions: AC joint dislocation type iii to type iv using tight rope with endobutton have excellent result give less complications and rigid fixation with extensive tensile strength allowing physiological motion between clavical and corocoid, endobutton avoid stress concentration over bone bridge between the two tunnels. Tight ropes prevents necessities of biological tendenous graft.
