Tienfenboeck TM et al. – This study reported long term follow–up outcomes of patients with acromioclavicular (AC) joint dislocation treated with Bosworth Screw and additional K–wiring. The authors concluded that despite its complications, the surgical procedure with Bosworth Screw and additional K–wiring was adequate with good–to–excellent functional outcome and highly satisfactory results in the majority of patients.

Methods

• In this single–center retrospective study, all patients operated for AC joint dislocation with Bosworth Screw and additional K–wire fixation were evaluated.

Results

• Among 22 eligible patients (male=20, mean age = 40 years ± 15.6 years), 3 grade–II, 13 grade–III, 4 grade–IV and 2 grade–V lesions graded according to Rockwood classification were noted.
• After at least 2 years of follow up (range 2–19 years), the overall mean clinical outcomes were found to be Constant 95, Disability of the Arm, Shoulder and Hand Score 6.4, American Shoulder and Elbow Surgeons 94.6, Simple Shoulder Test 99.02, University of California at Los Angeles Shoulder Score 33.1, Acromioclavicular Joint Instability 91.82 and Visual Analog Scale 0.29.
• Overall, 86%, 68% and 73% of patients reported very satisfied with achieved results, able to participate in every sports activity, and able to perform daily activity without limitations, respectively.
• Complications were reported in 14% of patients.
