“…[ 3 4 5 6 7 8 ] However, recent literature considers we should prefer the terminology of aponeurotic expansion or slip of the supraspinatus tendon, as described for the first time by Brodie in 1890, because it is not connected to the LHB despite its anatomical proximity. [ 2 9 10 ] A retrospective study of 150 shoulder magnetic resonance imaging (MRI) performed for various reasons at one institution and 50 US on cadaveric shoulders revealed that aponeurotic expansion of the supraspinatus located anterior and lateral to the LHB in its groove can be identified in about half of the shoulders on MRI or US.…”

Role of point-of-care ultrasonography (POCUS) in the diagnosing of acute medial meniscus injury of knee joint

Background In recent years, musculoskeletal ultrasound has increasingly become the common method for diagnosis for many medical specialties. Therefore, the present study was performed to evaluate the diagnostic value of point-of-care ultrasonography (POCUS) as a primary triage tool in the diagnosis of the acute medial meniscus injury of the knee. Materials and methods The present cross-sectional study was performed on patients with a suspected medial meniscus injury of the knee in the emergency department (ED). After history taking and primary physical examination, radiographic imaging of the knee was done. If there was no fracture in the knee X-ray, the POCUS examination on the knee was carried out. All the patients were asked to refer to an orthopedic clinic 2 weeks after discharge from ED for the Magnetic Resonance Imaging (MRI) evaluation. Finally, the POCUS findings were compared with the MRI findings in diagnosing medial meniscus injury. Results Fifty-five patients with a mean age of 35.48 ± 11.58 years were analyzed in the study (69.1% male). In comparison with MRI scan, the sensitivity and specificity of POCUS in the detection of medial meniscus injury were 85.0 [95% confidence interval (CI), 54.0 to 98.9] and 65.7% [95% CI 42.2 to 85.7], respectively. Its positive and negative predictive values were 58.6% [95% CI 33.8 to 81.5] and 88.5% [95% CI 62.1 to 99.3], respectively. (Area under the ROC curve = 0.726, P value = 0.003). Conclusion The present study demonstrated that POCUS can reasonably be applied in comparison with MRI to evaluate medial meniscus injury. POCUS is an effective initial diagnostic modality in patients with suspected medial meniscus injuries.

Purpose: The objective of this cadaveric study was to study the anatomic relationships between the rotator cuff muscles and the rotator cable. Methods: In 30 formaldehyde-fixed shoulders from 20 cadavers, the rotator cuff and rotator cable were dissected and the glenohumeral joint opened. The orientation and attachments of the rotator cable to the rotator cuff muscles were studied and the severity of any osteoarthritis, labral pathology, and rotator cuff pathology present was documented. The width and thickness of the infraspinatus attachments to the rotator cable were measured. Results: The infraspinatus muscle was noted to be more loosely adherent to the rotator cable, while the supraspinatus and teres minor were tightly adherent to the cable. Specifically, the superior-most portion of the infraspinatus was found to be less tightly adherent than the inferior-most portion in 26 of the 30 shoulders studied. There was a correlation between increased thickness of the inferior-most portion of infraspinatus and more-than-minimal osteoarthritis and labral pathology (p=0.0477, p=0.0409, respectively). Conclusions: While the supraspinatus and teres minor muscles were tightly adherent to the cable in all shoulders, the degree of attachment of the superior-most portion of the infraspinatus muscle was notably less in 26 of the 30 shoulders studied. This could mean that only the inferior portion of the infraspinatus participates in stress shielding through the cable or be a compensatory response to increased load on the tendon. This work is expected to provide insight into the function of the rotator cable and the different functions of the infraspinatus.
