A new tear pattern of the rotator cuff and its treatment: Fosbury flop tears.

Lädermann A, Denard PJ, Kolo FC - Int J Shoulder Surg (2015 Jan-Mar)

Bottom Line: A prospective radiologic and clinical study collected all patients with a magnetic resonance imaging arthrogram that underwent an arthroscopic rotator cuff repair over a 1 year period.Characteristic radiographic findings included a thicker tendon than normal, the presence of a stump and accumulation of liquid in the superior-medial part of the subacromial bursa, and adhesions between the supraspinatus tendon and the wall of the subacromial bursa.Level IV.

ABSTRACT

Purpose: The purpose of this report is to describe a new full-thickness tear pattern of the posterosuperior rotator cuff with reversal healing. We describe the specific radiologic signs associated with this tear pattern and the arthroscopic rotator cuff repair technique.

Materials and methods: A prospective radiologic and clinical study collected all patients with a magnetic resonance imaging arthrogram that underwent an arthroscopic rotator cuff repair over a 1 year period.

Results: Among 97 patients, five demonstrated a tear of the posterosuperior rotator cuff with reversal healing. Characteristic radiographic findings included a thicker tendon than normal, the presence of a stump and accumulation of liquid in the superior-medial part of the subacromial bursa, and adhesions between the supraspinatus tendon and the wall of the subacromial bursa.

Conclusion: Avulsion of the posterosuperior rotator cuff with reversal healing on its bursal-side is a less common condition. This type of lesion and distinct radiographic signs that can be recognized to facilitate anatomic repair of the rotator cuff.

Level of evidence: Level IV.

Figure 4: Coronal intermediate weighted image without fat saturation that shows the tendon stump projecting on top of the superomedial part of the subacromial bursa. A two-layered structure with the stump is clearly differentiated

Mentions: Compared to other patients with full-thickness tear patients with reversal healing showed distinct morphological differences. The mean thickness of the supraspinatus tendon was 11.2 ± 1.1 mm [Figure 3]. The tendon stump was visualized in five patients on the bursal-side of the retracted supraspinatus tendon arboring a superomedial orientation [Figure 4]. These patients also showed accumulation of fluid in the superomedial part of the subacromial bursa, and finally adhesions between the wall of the subacromial bursa and the supraspinatus tendon [Figure 5]. On T1-weighted images with fat saturation abnormal orientation of the tendon, fibers were always noted in the reversed healed stump. Fatty infiltration was stage 0 in three cases and stage 1 in two cases.
