S42.26 Fracture of lesser tuberosity of humerus

Name of the Condition

• Fracture of lesser tuberosity of humerus (ICD Code: S42.26)

Summary

This condition involves a fracture of the lesser tuberosity, a bony prominence on the humerus bone near the shoulder joint. The lesser tuberosity serves as an attachment point for the subscapularis muscle, and fractures in this area may affect muscle function or joint stability.

Causes

Fractures of the lesser tuberosity typically result from direct trauma, such as falls onto the shoulder, motor vehicle accidents, or high-impact sports injuries. Low-energy trauma may also cause this type of fracture in individuals with weakened bones.

Risk Factors

• Advanced age and osteoporosis, which reduce bone density.
• Participation in contact sports or activities with a high risk of falls.
• Previous fractures or bone disorders that weaken the skeletal structure.

Symptoms

• Intense pain in the shoulder or upper arm.
• Swelling, bruising, and visible deformity at the fracture site.
• Inability to move the arm or bear weight.
• Numbness or tingling in the hand or fingers if nerve involvement occurs.

Diagnosis

Physical examination to assess pain, range of motion, and deformity. Imaging tests, including X-rays, to visualize the fracture pattern and displacement. CT scans or MRIs may be used for detailed assessment of complex fractures or soft tissue damage.

Treatment Options

• Immobilization with a sling or brace to stabilize the fracture.
• Pain management with medications.
• Surgical intervention to realign and fixate bone fragments if the fracture is displaced or unstable.

Prognosis and Follow-Up

Recovery time varies depending on the severity of the fracture and treatment approach. Physical therapy may be recommended to restore strength and mobility. Follow-up imaging and clinical evaluations are typically performed to monitor healing progress.

Complications

• Nonunion or malunion of the fracture.
• Nerve or blood vessel damage.
• Chronic pain or stiffness in the shoulder.
• Reduced range of motion or muscle weakness.

Lifestyle & Prevention

• Engage in regular weight-bearing exercise to maintain bone density.
• Use protective gear during high-risk activities.
• Ensure adequate calcium and vitamin D intake to support bone health.
• Avoid falls by modifying the home environment (e.g., removing tripping hazards).

When to Seek Professional Help

Seek immediate medical attention if you experience severe pain, swelling, or deformity after a fall or injury. Contact a healthcare provider if symptoms worsen or do not improve with initial care.

Tips for Medical Coders

Document the fracture location (lesser tuberosity) and any associated details, such as displacement or open/closed status, to support accurate coding. Ensure clinical documentation aligns with the specific characteristics of the fracture for proper code assignment.
