S42.256 Nondisplaced fracture of greater tuberosity of unspecified humerus

Name of the Condition

• Nondisplaced fracture of greater tuberosity of unspecified humerus (ICD-10 Code: S42.256)

Summary

This condition involves a fracture of the greater tuberosity, a bony prominence on the upper end of the humerus (upper arm bone) near the shoulder joint, where the fracture fragments remain in their normal anatomical position without displacement. 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 if the fracture is unstable or fails to heal with conservative care.

Prognosis and Follow-Up

Most nondisplaced fractures heal well with conservative treatment, and patients often regain full shoulder function. Follow-up appointments monitor healing progress, and physical therapy may be recommended to restore mobility. Recovery time varies but typically ranges from several weeks to a few months.

Complications

• Delayed healing or nonunion of the fracture.
• Shoulder stiffness or reduced range of motion.
• Chronic pain or instability in the shoulder.
• Nerve or blood vessel injury in rare cases.

Lifestyle & Prevention

• Use protective gear during contact sports or high-risk activities.
• Maintain bone health through adequate calcium and vitamin D intake.
• Avoid falls by modifying the home environment (e.g., removing tripping hazards).
• Engage in regular exercise to strengthen shoulder muscles and improve balance.

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, pus) at the injury site.

Tips for Medical Coders

Document the fracture as nondisplaced and specify the humerus as unspecified. Ensure clinical notes confirm the absence of displacement and lack of laterality (right/left) to support the code S42.256. Include details on trauma mechanism, imaging findings, and treatment approach for accurate coding.
