Abstract
Purpose
Symptomatic acromioclavicular joint (ACJ) osteoarthritis causes pain and limitations in activities of daily living. Open and arthroscopic distal clavicle excision techniques have been described with good outcomes. However, both techniques have their own sets of advantages and disadvantages. This study describes a novel technique of percutaneous distal clavicle excision for symptomatic ACJ osteoarthritis and our two-year results.
Methods
Fifteen consecutive patients underwent percutaneous distal clavicle excision for ACJ arthritis. These patients had failed a trial of conservative treatment. The ACJ was confirmed as the pain generator with an intraarticular steroid/lignocaine injection, and shoulder MRI was used to exclude alternative pain generators in the shoulder. They had a minimum of two years of follow-up.
Results
At a mean of 26.8 months postoperatively, the mean VAS pain score was 0, and the mean Constant score for the shoulder was 87.3 points (range 50–94), which corresponded to 1 good, 1 very good and 13 excellent results. The mean SF-36 score was 94.9 points (range 65–100). There were statistically significant improvements in the VAS scores, Constant shoulder scores and SF-36 scores at one year and two years of follow-up (p < 0.05). Three unique complications, namely subcutaneous emphysema, “missing” of the distal clavicle and thermal skin injury, were encountered. Our surgical technique has since been modified to circumvent these complications.
Conclusion
Our novel technique of percutaneous distal clavicle excision yields a 93.3% good-to-excellent results based on the Constant shoulder score and durable pain relief based on VAS at two years.
