MATERIAL AND METHODS: We retrospectively identified 27 patients who underwent antegrade intramedullary nail fixation for traumatic humeral shaft fractures and received follow-up for at least 5 years post-operatively. The patients were divided into two groups: those without tears and those with partial or complete tears, diagnosed using ultrasonography. We compared the functional and radiological shoulder outcomes between the two groups.
RESULTS: Of the 27 patients, 10 had partial or complete supraspinatus tears with a mean follow-up of 7.5 years postoperatively. The incidence of acromial spurs was significantly higher in patients with partial or complete tears than in those without tears (P<0.001). There were no significant differences in the age and sex-adjusted Constant score, or the American Shoulder and Elbow Surgeon score between the two groups.
CONCLUSION: Our results revealed that 37% of patients developed partial or complete supraspinatus tendon tears in the mid-term. Post-operative rotator cuff tears were significantly associated with the formation of acromial spurs; however, they had no significant effect on mid-term shoulder functional outcomes.
