S42.264 Nondisplaced fracture of lesser tuberosity of right humerus

Name of the Condition

• Nondisplaced fracture of lesser tuberosity of right humerus (ICD Code: S42.264)

Summary

This condition involves a nondisplaced fracture of the lesser tuberosity, a bony prominence on the front of the right humerus near the shoulder joint. The fracture does not involve significant separation of bone fragments, preserving the structural alignment of the tuberosity and its attachment to the subscapularis muscle.

Causes

Nondisplaced 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 confirm nondisplacement. 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 support healing.
• Pain management with medications or ice therapy.
• Physical therapy to restore strength and mobility once healing progresses.
• Surgical intervention if displacement occurs or if conservative measures fail.

Prognosis and Follow-Up

Most nondisplaced fractures heal well with conservative treatment, though recovery may take several weeks to months. Follow-up imaging and physical therapy assessments are typically recommended to monitor progress and ensure proper healing.

Complications

• Delayed union or nonunion of the fracture.
• Nerve or blood vessel damage near the fracture site.
• Chronic pain or reduced shoulder function.
• Post-traumatic arthritis in the shoulder joint.

Lifestyle & Prevention

• Use protective gear during high-risk activities.
• Maintain bone health through diet and exercise.
• Avoid falls by modifying home environments for safety.
• Strengthen shoulder muscles to improve stability.

When to Seek Professional Help

Seek immediate medical attention if severe pain, swelling, or deformity occurs after an injury. Contact a healthcare provider if symptoms worsen or do not improve with initial treatment.

Tips for Medical Coders

Document the nondisplaced nature of the fracture and specify the right humerus to support accurate coding. Include details about trauma mechanism, imaging findings, and treatment plans to ensure comprehensive clinical documentation.
