All arthroscopic augmented Vargas procedure: An option after failed acromioclavicular joint dislocation...

Area of Science:

• Orthopedic Surgery
• Arthroscopic Techniques
• Shoulder Reconstruction

Background:

• The Weaver-Dunn procedure is a common treatment for acromioclavicular joint instability.
• Salvage options after failure of the Weaver-Dunn procedure are limited.
• Arthroscopic revision techniques are desirable for minimally invasive treatment.

Purpose of the Study:

• To describe a novel all-arthroscopic revision procedure for failed Weaver-Dunn repairs.
• To evaluate the efficacy of the Vargas procedure using a vascularized conjoint tendon transfer augmented with an artificial coraco-clavicular ligament.

Main Methods:

• Two patients underwent an all-arthroscopic revision procedure.
• A vascularized conjoint tendon was harvested, tubularized, and transferred to the distal clavicle.
• An artificial coraco-clavicular ligament was used to augment the tendon transfer.

Main Results:

• No complications were reported in the two patients.
• At a minimum two-year follow-up, there was no recurrence of acromioclavicular joint instability.
• Patients achieved normal range of motion and returned to sport.

Conclusions:

• The Vargas procedure is a feasible and effective arthroscopic salvage technique for failed Weaver-Dunn procedures.
• This technique restores shoulder stability and function, allowing patients to return to athletic activities.
