The greater tubercle of the humerus, a prominent bony projection, serves as a critical attachment site for rotator cuff muscles, but its associated muscles can be challenging for medical students to memorize. The mnemonic “Sally and Ingrid Teach Maths” offers a concise and engaging way to recall the three rotator cuff muscles—supraspinatus, infraspinatus, and teres minor—that attach to this structure. This tool aids students in mastering shoulder anatomy for exams and enhances clinical understanding, particularly in diagnosing rotator cuff injuries or planning shoulder surgeries.

Mnemonic Breakdown
S
S stands for the supraspinatus, a rotator cuff muscle that attaches to the superior facet of the greater tubercle. It initiates shoulder abduction and stabilizes the humeral head in the glenoid cavity, crucial for arm elevation. Supraspinatus tears, common in repetitive overhead activities, can cause significant shoulder weakness and pain.
I
I represents the infraspinatus, a rotator cuff muscle that attaches to the middle facet of the greater tubercle. It externally rotates the humerus and stabilizes the shoulder joint, supporting movements like throwing. Infraspinatus injuries, often from sports or trauma, can limit external rotation and compromise shoulder stability.
T
T denotes the teres minor, a rotator cuff muscle that attaches to the inferior facet of the greater tubercle. It assists in external rotation and adduction of the humerus, contributing to shoulder joint integrity. Teres minor dysfunction, though less common, can impair fine motor control in the shoulder.
M
M refers to the muscles collectively, emphasizing the role of the supraspinatus, infraspinatus, and teres minor as part of the rotator cuff. These muscles work synergistically to stabilize and move the shoulder, critical for daily activities and athletic performance. Injuries to these muscles, such as tears or strains, often require precise diagnosis to guide treatment.

Summary and Clinical Context
The “Sally and Ingrid Teach Maths” mnemonic simplifies the recall of the three rotator cuff muscles—supraspinatus, infraspinatus, and teres minor—that attach to the greater tubercle of the humerus, into a vivid, easy-to-remember phrase. By linking each muscle to a specific letter, it creates a clear framework that aligns with their anatomical roles, making it an effective tool for medical students during exams and clinical rotations. Its catchy structure ensures quick recall under pressure, such as when assessing patients with rotator cuff tears or interpreting imaging for shoulder impingement. The mnemonic fosters both rapid memorization and a deeper understanding of shoulder anatomy, essential for clinical proficiency.
In clinical settings, knowledge of the greater tubercle’s muscle attachments is critical for diagnosing and managing conditions like rotator cuff tears, which affect approximately 20% of the population over 60, often resulting from repetitive overhead motions or acute trauma. Shoulder impingement, frequently involving the supraspinatus due to its position under the acromion, can cause pain and restricted motion, requiring targeted physical therapy or surgical decompression. Infraspinatus or teres minor injuries, though less common, may contribute to shoulder instability, necessitating precise imaging and sometimes arthroscopic repair. The mnemonic aids students in identifying these muscles during physical exams or imaging, enhancing diagnostic accuracy and informing treatment plans, such as conservative management or surgical intervention for humeral fractures involving the greater tubercle.
The mnemonic’s benefits extend beyond rote learning, supporting interdisciplinary applications for radiologists, orthopedic surgeons, and physical therapists. Radiologists rely on knowledge of these muscle attachments to interpret MRI scans for tears or inflammation, while surgeons use it to navigate procedures like rotator cuff repair or greater tubercle fracture fixation. Students can enhance retention by pairing the mnemonic with visual aids, such as 3D humerus models, or integrating it with related mnemonics, such as “CRAzy TULips” for humerus epicondyles, to build a comprehensive skeletal framework. Its simplicity makes it valuable for beginners mastering foundational anatomy and advanced learners preparing for specialties like orthopedics or sports medicine, where precise shoulder knowledge is paramount.
The mnemonic’s blend of clarity and clinical relevance empowers students to excel academically and in patient care. By embedding the rotator cuff muscles in an engaging phrase, it transforms a complex topic into an accessible, confidence-building tool. Whether studying for board exams or evaluating a patient with a suspected supraspinatus tear, “Sally and Ingrid Teach Maths” equips learners with the knowledge to navigate shoulder anatomy effectively. Its practical utility in high-stakes scenarios, such as trauma assessments or surgical planning, underscores its value as an indispensable educational resource.
Furthermore, the mnemonic fosters a structured approach to learning that aligns with the demands of medical education. By breaking down the greater tubercle’s muscle attachments into a memorable sequence, it reduces cognitive overload, allowing students to focus on clinical correlations, such as the role of the infraspinatus in external rotation or the supraspinatus in abduction. Its versatility supports long-term retention, enabling students to recall shoulder anatomy years into their careers, whether in emergency medicine or rehabilitation. Ultimately, “Sally and Ingrid Teach Maths” not only boosts academic performance but also enhances patient outcomes by enabling accurate diagnoses and tailored treatments.
