Distal insertional anatomy of the triceps brachii muscle: MRI assessment in cadaveric specimens Employing Histologic Correlation and Play-doh ® Models of the Anatomic Findings / Francisco Alejandro Ramírez Ruiz
Título : Distal insertional anatomy of the triceps brachii muscle: MRI assessment in cadaveric specimens Employing Histologic Correlation and Play-doh ® Models of the Anatomic Findings Tipo de documento : documento electrónico Autores : Francisco Alejandro Ramírez Ruiz, Fecha de publicación : 2020 Títulos uniformes : Skeletal Radiology Idioma : Inglés (eng) Palabras clave : Cadavers Insertion anatomy Magnetic resonance imaging Triceps brachii tendon Resumen : Objectives: Assess the insertional anatomy of the distal aspect of the triceps brachii muscle using magnetic resonance imaging (MRI) in cadavers with histologic correlation and Play-doh® models of the anatomic findings. Materials: Elbows were obtained from twelve cadaveric arm specimens by transverse sectioning through the proximal portion of the humerus and the midportion of the radius and ulna. MRI was performed in all elbows. Two of the elbow specimens were then dissected while ten were studied histologically. Subsequently, Play-doh® models of the anatomic findings of the distal attachment sites of the triceps brachii muscle were prepared. Results: MRI showed a dual partitioned appearance of the distal attachment sites into the olecranon in all specimens. In the deeper tissue planes, the medial head muscle insertion was clearly identified while superficially, the terminal portion of the long and lateral heads appeared as a conjoined tendon. Histologic analysis, however, showed continuous tissue rather than separate structures attaching to the olecranon. Conclusion: Although MRI appeared to reveal separate and distinct attachments of the triceps brachii muscle into the olecranon, histologic analysis delineated complex but continuous tissue related to the attachments of the three heads of this muscle. The Play-doh® models were helpful for the comprehension of this complex anatomy and might serve as a valuable educational tool when applied to the analysis of other musculoskeletal regions.

Título : High origin of the anterior band of the inferior glenohumeral ligament: MR arthrography with anatomic and histologic correlation in cadavers Tipo de documento : documento electrónico Autores : Francisco Alejandro Ramírez Ruiz, Fecha de publicación : 2012 Títulos uniformes : Skeletal Radiology Idioma : Inglés (eng) Palabras clave : Shoulder Inferior glenohumeral ligament Labrum MRI Arthrography Resumen : Introduction: The anterior band of the inferior glenohumeral ligament has been described to arise from the anteroinferior labrum, but we have observed that in some persons its origin is from the anterior or anterosuperior labrum, creating diagnostic difficulties. Materials and methods: Ten fresh unembalmed cadaveric shoulders underwent magnetic resonance arthrography (MRA) using a posterior approach with a 1.5 T GE magnet, with the following sequences: T1-weighted fast spin-echo in axial, coronal and sagittal planes, and T1 fat-suppressed spin-echo in the axial plane (TR/TE 600/20, section thickness 2.5 mm, 0.5 mm interslice space, number of signals acquired, two, field of view 12 × 12 cm, and matrix 512 × 256 pixels). Following imaging, the shoulders were frozen and later sectioned using a band saw into 3-mm sections corresponding to the axial imaging plane. Histological analysis was also performed to determine the origin of the anterior band. Results: Four of the ten shoulders had an origin of the anterior band above or at the 3 o’clock position: one at the 1 o’clock position, two at the 2 o’clock position, and one at the 3 o’clock position. In another shoulder, the anterior band of the inferior glenohumeral ligament originated from the middle glenohumeral ligament, and in five other shoulders, the anterior band originated from the anteroinferior labrum as has been described in the literature. Conclusions: This finding is of clinical significance as a high origin of the anterior band of the inferior glenohumeral ligament leads to MR arthrographic finding that can simulate those of labral tears or detachments.
