The existence of cords in olecranon bursae.

BACKGROUND

The purpose of this study was to document the existence of transverse cords in olecranon bursae in patients undergoing excision of the bursa and to describe the unique clinical presentation of patients with these cords.

METHODS

A retrospective study was performed on 24 patients who had surgery to excise an olecranon bursa between 2006 and 2011. The patient's history, preoperative radiographs, ultrasound images, intraoperative photographs, and findings on histologic analysis were reviewed in all cases.

RESULTS

Nine olecranon bursae had cords (cord group) and 15 did not have cords (noncord group). All patients in the cord group were male manual laborers, and nearly all had olecranon enthesophytes (n = 8). Patients in the noncord group had associated medical conditions or an infection. A higher level of satisfaction was reported in the noncord group after surgical excision.

CONCLUSION

This study documents the existence of transverse cords oriented at right angles to the long axis of the olecranon. Olecranon bursae with cords have a unique presentation and are found in male manual workers, are nearly always associated with an olecranon enthesophyte, and do not present with infections.
