Differential Diagnosis for Rotator Cuff Strain
Single Most Likely Diagnosis
- Rotator cuff tendinitis: This is the most likely diagnosis due to the common presentation of pain and limited mobility in the shoulder, which are typical symptoms of rotator cuff injuries.
Other Likely Diagnoses
- Adhesive capsulitis (frozen shoulder): This condition can present with similar symptoms to rotator cuff strain, including pain and limited range of motion in the shoulder.
- Bursitis: Inflammation of the bursae in the shoulder can cause pain and stiffness, mimicking the symptoms of a rotator cuff strain.
- Labral tear: A tear in the labrum, the cartilage surrounding the socket of the shoulder joint, can cause pain and limited mobility, similar to a rotator cuff strain.
Do Not Miss Diagnoses
- Fracture: A fracture of the humerus, scapula, or clavicle can present with severe pain and limited mobility, and must be ruled out to avoid delayed diagnosis and treatment.
- Dislocation: A dislocation of the shoulder joint can cause severe pain and deformity, and requires prompt recognition and treatment.
- Axillary nerve injury: Injury to the axillary nerve can cause weakness and numbness in the shoulder and arm, and must be recognized to avoid delayed treatment and potential permanent damage.
Rare Diagnoses
- Osteonecrosis: Avascular necrosis of the humeral head can cause pain and limited mobility in the shoulder, although it is a less common condition.
- Infection: Septic arthritis or osteomyelitis can present with pain, swelling, and limited mobility in the shoulder, although these conditions are relatively rare.
- Tumor: A tumor in the shoulder region, such as a soft tissue sarcoma, can cause pain and limited mobility, although this is a very rare diagnosis.
