S42.255 Nondisplaced fracture of greater tuberosity of left humerus

Name of the Condition

• Nondisplaced fracture of greater tuberosity of left humerus (ICD-10 Code: S42.255)

Summary

This condition involves a fracture of the greater tuberosity, a bony prominence on the upper end of the left humerus (upper arm bone) near the shoulder joint. The fracture is nondisplaced, meaning the bone fragments remain in their normal anatomical position. The greater tuberosity serves as an attachment point for shoulder muscles and ligaments, and its fracture may affect shoulder function.

Causes

Fractures of the greater tuberosity typically result from direct trauma, such as a fall onto the shoulder, a direct blow to the area, or forceful muscle contraction (e.g., during sports or lifting). Low-energy trauma may also cause the injury in individuals with weakened bones.

Risk Factors

• Participation in contact sports or activities with a high risk of falls.
• Osteoporosis or other conditions that weaken bone density.
• Advanced age, which increases susceptibility to fractures.
• Previous shoulder injuries or surgeries.

Symptoms

• Acute pain in the shoulder or upper arm.
• Swelling, bruising, and tenderness around the shoulder.
• Difficulty moving the arm, especially with overhead motions.
• Possible deformity or visible lump at the fracture site.

Diagnosis

Physical examination to assess pain, swelling, and range of motion. Imaging tests, such as X-rays, are used to confirm the fracture and evaluate displacement. CT scans or MRIs may be ordered for detailed assessment if needed.

Treatment Options

• Conservative management with rest, ice, and pain relief.
• Immobilization using a sling or brace to support the shoulder.
• Physical therapy to restore range of motion and strength.
• Surgical intervention is rarely required for nondisplaced fractures but may be considered in specific cases.

Prognosis and Follow-Up

Most nondisplaced fractures heal well with conservative treatment. Full recovery typically occurs within 6–12 weeks, depending on the individual’s age and overall health. Follow-up appointments monitor healing and functional recovery.

Complications

• Delayed union or nonunion of the fracture.
• Chronic pain or stiffness in the shoulder.
• Reduced range of motion or strength.
• Rarely, associated nerve or blood vessel injury.

Lifestyle & Prevention

• Use proper techniques during sports or physical activities to avoid falls.
• Maintain bone health through adequate calcium and vitamin D intake.
• Wear protective gear during high-risk activities.
• Avoid overexertion or repetitive overhead motions that strain the shoulder.

When to Seek Professional Help

Seek immediate medical attention if you experience severe pain, inability to move the arm, visible deformity, or signs of infection (e.g., fever, redness, drainage) at the injury site.

Tips for Medical Coders

Document the side (left), fracture type (nondisplaced), and anatomical location (greater tuberosity of humerus) to ensure accurate coding. Include details on trauma mechanism, imaging results, and treatment approach to support code specificity.
