S42.262 Displaced fracture of lesser tuberosity of left humerus

Name of the Condition

• Displaced fracture of lesser tuberosity of left humerus (ICD Code: S42.262)

Summary

This condition involves a displaced fracture of the lesser tuberosity, a bony prominence on the front of the left humerus near the shoulder joint. The fracture is characterized by the separation of bone fragments, which may affect the attachment of the subscapularis tendon and surrounding structures.

Causes

Displaced fractures of the lesser tuberosity typically result from direct trauma, such as a fall onto the shoulder or a forceful pull on the arm. High-impact injuries, including motor vehicle accidents or sports-related collisions, may also cause this type of fracture.

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

Treatment depends on fracture severity and displacement. Non-surgical options include immobilization with a sling and physical therapy. Surgical intervention may be required for significant displacement, involving open reduction and internal fixation to realign and stabilize the bone.

Prognosis and Follow-Up

Most patients recover well with appropriate treatment, though recovery time varies. Follow-up care includes monitoring for healing, physical therapy to restore function, and imaging to assess bone union. Long-term outcomes depend on fracture severity and adherence to rehabilitation.

Complications

Potential complications include nonunion or malunion of the fracture, shoulder stiffness, nerve or blood vessel damage, and post-traumatic arthritis. Infection may occur if surgery is performed.

Lifestyle & Prevention

Avoid high-risk activities that may lead to falls or direct trauma. Maintain bone health through a balanced diet rich in calcium and vitamin D, and engage in weight-bearing exercises to strengthen bones. Use protective gear during sports.

When to Seek Professional Help

Seek immediate medical attention if you experience severe shoulder pain, swelling, deformity, or inability to move the arm after an injury. Numbness, tingling, or weakness in the hand or fingers also warrants prompt evaluation.

Tips for Medical Coders

Document the fracture's displacement, laterality (left), and any associated injuries. Ensure clinical notes specify the fracture type (e.g., closed, open) and encounter details (e.g., initial, subsequent) for accurate coding. Verify that imaging results support the diagnosis.
