Differential Diagnosis for Wrist Injury with Lateral Side to Side Movement Pain
Single Most Likely Diagnosis
- Scapholunate Ligament Sprain or Tear: This is a common injury that occurs when the wrist is subjected to a fall onto an outstretched hand, causing pain with lateral side to side movement due to the instability of the scapholunate joint.
Other Likely Diagnoses
- Triangular Fibrocartilage Complex (TFCC) Injury: The TFCC is a ligamentous structure on the ulnar side of the wrist that can be injured with a fall or sudden twisting motion, leading to pain with lateral movement.
- Wrist Fracture (e.g., Scaphoid Fracture): A fracture of one of the carpal bones, such as the scaphoid, can cause pain with movement, especially with lateral side to side motion.
- Ganglion Cyst: A ganglion cyst is a benign lump that can form on the wrist, causing pain and discomfort, especially with certain movements.
Do Not Miss Diagnoses
- Infectious Arthritis: Although less common, infectious arthritis of the wrist joint can cause severe pain and limited mobility, and if not promptly treated, can lead to serious complications.
- Osteonecrosis (e.g., Kienböck's Disease): A condition where the blood supply to one of the carpal bones (usually the lunate) is disrupted, leading to bone death and potentially severe wrist pain.
Rare Diagnoses
- Madelung's Deformity: A rare congenital condition affecting the distal radius and ulna, leading to abnormal wrist alignment and potential pain with movement.
- Tumor (e.g., Giant Cell Tumor of the Tendon Sheath): Although rare, tumors of the wrist can cause pain and limited mobility, and their diagnosis is crucial for appropriate management.
