摘要

Background

Elastofibroma dorsi (ED) is a rare benign soft tissue tumour that usually occurs in the subscapular region of the back. Clinical presentation often includes the presence of a painless, slowly growing mass in the infrascapular region, which may be accompanied by shoulder discomfort or restricted movement.

Objective

This study aimed to contribute to the existing literature on the long-term outcomes of Elastofibroma dorsi by examining a series of 13 patients’ clinical features, imaging data, demographical data, and pre- and post-operative functional scores and also to investigate the relation between Elastofibroma dorsi and shoulder impingement.

Method

We have retrospectively analysed the radiological, clinical, demographical, and functional data of 13 patients from a single centre. Ipsilateral shoulder X-rays are examined for shoulder impingement using radiological parameters such as acromiohumeral distance, lateral acromial angle, and acromial index. The functional scores, including Constant Score, Q-Dash, and VAS were evaluated.

Results

There were 13 patients (9 females and 4 males) with a mean age of 59.9 years (range 53–68 years). The mean follow-up was 65.6 months (range 11–131 months). The tumour side was right in 6 (46%) patients and left in 5 (38%) patients, and the tumour was diagnosed bilaterally in 2 patients (15%). The pre-operatively mean Constant Score was 67.3 and improved to 85 post-operatively (p < 0.001). Pre-operatively, the mean quick-DASH score was 35.3 and improved to 15, 5 post-operatively (p < 0.001). Pre-operatively, the mean VAS score was 5.4 (range 0–10) and improved to 1.69 (range 0–5) post-operatively (p < 0.001). Pre-operatively, the mean flexion value was 137.7° and improved to 161.2°.

Conclusion

Our results show that shoulder impingement due to acromion abnormality could be relevant to scapulothoracic dyskinesia and ED. Further studies are needed to reveal the exact etiopathogenesis of ED
