Summary
A young military cadet experienced right shoulder fatigue and weakness. Magnetic resonance imaging revealed a posterior labral tear and paralabral cyst compressing the suprascapular nerve.
Area of Science:
- Orthopaedic Surgery
- Sports Medicine
- Neurology
Background:
- A 21-year-old military academy cadet presented with a one-week history of right shoulder fatigue and discomfort.
- The patient sought physical therapy via direct access due to the chief complaint.
Observation:
- Physical examination revealed significant muscle atrophy and weakness in the affected shoulder.
- No history of traumatic injury was reported by the patient.
Findings:
- Orthopaedic consultation and diagnostic imaging were pursued due to the unexplained symptoms.
- Magnetic resonance imaging (MRI) identified a posterior labral tear with a large paralabral cyst.
- The paralabral cyst was deemed the likely cause of significant compression on the suprascapular nerve.
Implications:
- This case highlights the importance of considering nerve compression in cases of shoulder pain and atrophy without clear injury.
- Early diagnosis through advanced imaging is crucial for appropriate management of suprascapular nerve impingement.
- Understanding the relationship between labral tears, cysts, and nerve dysfunction is vital for physical therapists and orthopaedic surgeons.

01:29Herniated Intervertebral Disc l: Introduction
Intervertebral disc herniation refers to the displacement of the nucleus pulposus (the gel-like inner core of the disc) through a tear or weakened area in the annulus fibrosus (the outer fibrous ring). The displaced disc material extends beyond the normal boundaries of the disc space and may compress or irritate nearby spinal nerve roots or, less commonly, the spinal cord.Etiology and Risk FactorsHerniation commonly results from degeneration, in which aging reduces disc hydration and...
01:23Muscles of the Shoulder
The muscles surrounding the shoulder girdle, including the clavicle and scapula, primarily stabilize the scapula. This stable base allows other muscles to move the humerus effectively. Scapular movements often mirror those of the humerus and extend its range of motion. For instance, raising the arm above the head would not be feasible without simultaneous upward rotation of the scapula.

01:31Muscles that Move the Arm
Nine muscles are involved in arm movements. Two of these, the pectoralis major and latissimus dorsi, originate from the axial skeleton and are called axial muscles. The other seven originate from the scapula and are called the scapular muscles.
The pectoralis major has two origins. Its clavicular head originates on the medial half of the clavicle. In contrast, the sternocostal head originates on the costal cartilages of ribs 1-6, the sternum, and the aponeurosis of the external oblique of the...
