Summary
Luxatio erecta humeri, a rare shoulder dislocation, commonly shows rotator cuff tears and ligament injuries on MRI. Recognizing these findings aids in diagnosing this specific inferior glenohumeral dislocation.
Area of Science:
- Orthopedic Surgery
- Radiology
- Musculoskeletal Imaging
Background:
- Luxatio erecta humeri is a rare inferior glenohumeral dislocation.
- Its specific magnetic resonance imaging (MRI) findings are not well-documented in radiology literature.
Purpose of the Study:
- To identify and describe the characteristic MRI findings associated with luxatio erecta humeri.
Main Methods:
- Retrospective review of MRI scans from four patients with luxatio erecta humeri.
- Evaluation for rotator cuff, biceps tendon, labral, ligament, bone, and cartilage pathology.
Main Results:
- All patients had glenohumeral joint pathology.
- Common findings included rotator cuff tears (supraspinatus, infraspinatus, subscapularis), biceps tendon pathology, glenoid labrum and inferior glenohumeral ligament (anterior and posterior bands) injuries.
- Humeral head contusions/fractures and cartilage abnormalities were also observed.
Conclusions:
- MRI findings of rotator cuff tears, labral tears, and inferior glenohumeral ligament injuries are common in luxatio erecta humeri.
- These findings support the mechanism of injury and can suggest this specific type of dislocation.

01:19Bones of the Upper Limb: Humerus
The upper limb consists of the arm, forearm, wrist, and hand bones. The humerus is the single bone of the upper arm region. Proximally, it has a large, spherical, smooth head that articulates with the glenoid cavity of the scapula to form the glenohumeral or shoulder joint. The margin of the head is the anatomical neck, a residual epiphyseal plate. Laterally it extends to form bony projections called the greater tubercle and the lesser tubercle. Next to the tubercles is the surgical neck, a...

Magnetic resonance imaging (MRI) is a noninvasive medical imaging technique based on a phenomenon of nuclear physics discovered in the 1930s, in which matter exposed to magnetic fields and radio waves was found to emit radio signals. In 1970, a physician and researcher named Raymond Damadian noticed that malignant (cancerous) tissue gave off different signals than normal body tissue. He applied for a patent for the first MRI scanning device in clinical use by the early 1980s. The early MRI...

Introduction:Magnetic Resonance Imaging, or MRI, can include a specialized imaging technique of the urinary system known as Magnetic Resonance Urography (MRU). This radiation-free technique uses strong magnetic fields and radio waves to produce detailed images with the help of a computer. MRU is particularly effective for visualizing fluid-filled structures like the kidneys, ureters, and bladder.Applications of MRI in the Genitourinary SystemKidneys and Ureters: MRI detects tumors, cysts,...
