Sonographic and MRI Presentation of Geyser Sign in Rotator Cuff Tears

Limited cases of rotator cuff tears with acromioclavicular (AC) degeneration in association with cystic swelling or ganglion cyst have been described till date. The “geyser radiographic sign” was originally described by Craig in 1984. Its significance was to document a tear in the articular capsule of the AC joint in the setting of a chronic full-thickness tear of the rotator cuff, which gave the appearance of a geyser arising from the subacromial bursa as radiographic contrast tracked through the AC joint to project superiorly from the shoulder. An 82-year-old male presented with pain on rest in the left shoulder and with difficulty in overhead abduction from last few months. MRI showed near complete full-thickness tear of supraspinatus tendon with retraction of the tendon and reduced bulk of the supraspinatus muscle with associated superior subluxation of humerus with AC arthropathic changes causing ganglion cyst and incidental finding of superior labrum anterior and posterior tear. AC cysts are further divided into Type 1 and Type 2. Repeated aspirations of these masses are not advised, as they often recur and repeated attempts at aspiration may lead to formation of a draining fistula. MRI geyser sign is highly suggestive of a benign process, which suggests underlying rotator cuff pathology.

The Relationship

Degenerative tears of the rotator cuff tendons are a significant clinical problem, with an incidence of more than 30% in asymptomatic persons over the age of 60 [1]. As the population continues to age, the incidence of partial and full-thickness rotator cuff tears continues to increase [2], with previous studies finding that greater age also correlates with worse surgical outcomes and increased fatty degeneration in the tissue [3]. Although the relationship between age, rotator cuff injury, and poor treatment outcomes has been previously established, insufficient information exists on the biological and mechanical changes in the tissue due to aging.

And Control

Background: The benefits of the interval slide (IS) procedure in retracted rotator cuff tears remain controversial. Purpose: The purpose was to evaluate the effect of the IS procedure on repair tension (RT). It was hypothesized that the IS procedure (anterior IS [AIS], posterior IS [PIS], and intra-articular capsular release [CR]) would reduce the RT of a supraspinatus tendon. Study Design: Controlled laboratory study. Methods: A total of 31 Thiel-embalmed human cadaveric shoulders (mean age, 74 years; range, 68-84 years) were tested. Full-thickness supraspinatus tendon tears were created, and 1 cm of tendon was resected to simulate a retracted defect. Shoulders were randomized into intervention (n = 16) and control (n = 15) groups. In all shoulders, the load during tendon reduction to footprint was measured, an endpoint was defined as maximum tendon lateralization before 50 N was reached, and the RT (load during lateralization to endpoint) of the native tendon (t1) was evaluated. In the intervention group, AIS (t2), PIS (t3), and CR (t4) were performed in order, with RT measurement after each step. In the control group, RT was assessed at the same time points without the intervention. Results: A complete reduction of the tendon was not achieved in any of the shoulders. Mean maximum lateralization was 6.7 ± 1.30 mm, with no significant differences between groups. In the intervention group, the overall IS procedure reduced RT about 47.0% (t1 vs t4: 38.7 ± 3.9 vs 20.5 ± 12.3 N; P < .001). AIS reduced RT significantly (t1 vs t2: 38.7 ± 3.9 vs 27.4 ± 10.5 N; P < .001), whereas subsequent PIS (t2 vs t3: 27.4 ± 10.5 vs 23.2 ± 12.4 N; P = .27) and CR (t3 vs t4: 23.2 ± 12.4 vs 20.5 ± 12.3 N; P = .655) did not additionally reduce tension. Comparison between groups at t4 revealed a reduction of RT of about 47.8% (control vs intervention: 39.3 ± 4.0 vs 20.5 ± 12.3 N; P < .001). Conclusion: The IS procedure reduces RT of the supraspinatus tendon in human cadaveric shoulders. However, performing PIS and CR subsequent to AIS does not reduce tension additionally. Clinical Relevance: These findings provide surgeons with a biomechanical rationale regarding the efficacy of the IS procedure.

Cuff Repair

Objectives: Rotator cuff tears lead to significant morbidity due to pain and decreased function. Despite the prevalence of cuff repairs, mid-term outcomes have been scarcely reported. The purpose of this study is to report minimum 5-year outcomes and clinical survivorship after double-row rotator cuff repair for full-thickness supraspinatus tendon tears. Methods: Patients at least five years out from arthroscopic double-row repair for a full-thickness cuff tear involving the supraspinatus tendon were included. Pre- and postoperative ASES, SF-12 PCS, QuickDASH, SANE, and satisfaction scores were collected. The relationship between outcomes and (1) tear chronicity, (2) number of tendons involved, (3) type of repair, and (4) primary versus revision procedure, was also evaluated. Kaplan-Meier survivorship analysis was conducted defining failures as progression to revision rotator cuff surgery. Results: From November 2005 to February 2012, a total of 189 shoulders were eligible for inclusion. Fifteen shoulders (7.9%) underwent revision rotator cuff repair and were considered failures. Outcomes data were reported at a mean follow-up of 6.6 (range, 5.0-11.0) years. All outcome scores significantly improved from pre- to postoperative time point, including mean ASES (57.9 to 92.9, P < 0.001), SF-12 PCS (43.4 to 52.0, P < 0.001), QuickDASH (35.2 to 10.5, P < 0.001), and SANE scores (61.5 to 86.5, P < 0.001). Acute tears demonstrated significantly better ASES and SANE scores than chronic tears (ASES 95.1 ± 8.9 versus 91.7 ± 11.2, P = 0.025; SANE 89.6 ± 19.9 versus 85.7 ± 21.3, P = 0.042). No other analyzed variable had a significant association with outcomes scores ( P > 0.05). Survivorship analysis demonstrated a postoperative clinical survivorship of the repair of 96.5% at two years and 93.8% at five years (Figure 1). Conclusion: Patients can expect excellent clinical outcomes and a low failure rate following arthroscopic double-row repair of full-thickness supraspinatus tears at mid-term follow-up. The repair of acute tears and primary repairs were associated with better postoperative outcomes.

Abstract Background Objectives: To comparatively evaluate the role of ultrasound and MRI in rotator cuff and biceps tendon pathologies and to establish ultrasound as a consistently reproducible, quick and accurate primary investigation modality sufficient to triage patients requiring surgical correction of full thickness rotator cuff tears. Methods: Fifty patients, clinically suspected to have rotator cuff and/or biceps tendon pathologies, with no contraindications to MRI, were evaluated by US and MRI, in a prospective cross-sectional observational study. US was done with high-frequency linear probe, and MRI was done on a 1.5-T scanner using T1 oblique sagittal, proton density (PD)/T2 fat-suppressed (FS) oblique sagittal, T1 axial, PD/T2 FS axial, T1 oblique coronal, T2 oblique coronal and PD FS oblique coronal sequences. Statistical testing was conducted with the statistical package for the social science system version SPSS 17.0. The sensitivity, specificity, PPV, NPV and accuracy were also calculated to analyze the diagnostic accuracy of US findings correlating with MRI findings. A p value less than 0.05 was taken to indicate a significant difference. Results Mean age was 45 years; 74% patients were males; 77% females and 60% males had tears. Majority of patients with rotator cuff tears were in the sixth decade of life. The frequency of tears was higher among older patients. Fourteen percent of patients had full thickness tears while 64% had partial thickness tears. US was comparable to MRI for detection of full thickness tears with overall sensitivity, specificity, PPV and accuracy of 93.8%, 100%, 100% and 98.2%, respectively (p value < 0.001). For partial thickness tears, US had overall sensitivity, specificity, PPV and accuracy of 75.6%, 82.6%, 89.5% and 78%, respectively (p value < 0.001), as compared to MRI. Subacromial-subdeltoid bursal effusion and long head of biceps tendon sheath effusion were common associated, though, non-specific findings. Conclusion Ultrasound findings in our study were found to be in significant correlation with findings on MRI in detection of rotator cuff tears. US was equivalent to MRI in detection of full thickness tears and fairly accurate for partial thickness tears. Therefore, US should be considered as the first line of investigation for rotator cuff pathologies.
