S82.55 Nondisplaced fracture of medial malleolus of left tibia

Name of the Condition

• Nondisplaced fracture of medial malleolus of left tibia

Summary

A nondisplaced fracture of the medial malleolus of the left tibia is a break in the inner bony prominence of the lower leg (tibia) near the ankle, where the bone fragments remain in their normal alignment. This injury typically affects the stability of the ankle joint but may not require surgical intervention if the alignment is maintained. The severity and treatment approach depend on the fracture pattern and associated joint involvement.

Causes

Fractures of the medial malleolus typically result from direct trauma, such as falls, twisting injuries, or high-impact events like sports collisions or motor vehicle accidents. Sudden rotational forces or excessive stress on the ankle joint can also lead to this type of fracture.

Risk Factors

• Participation in activities with a high risk of ankle injury, such as contact sports or gymnastics.
• Osteoporosis or other bone-weakening conditions that reduce bone density.
• Previous ankle injuries or surgeries that may weaken the joint.
• Age-related bone loss, particularly in older adults.

Symptoms

• Pain and swelling localized to the inner ankle.
• Difficulty bearing weight on the affected foot.
• Bruising and tenderness at the fracture site.
• Possible deformity or misalignment of the ankle if the fracture is displaced.

Diagnosis

Diagnosis involves a physical examination to assess pain, swelling, and range of motion. Imaging studies, such as X-rays, are used to confirm the fracture and evaluate the degree of displacement. In some cases, a CT scan may be used to assess complex fractures or associated joint damage.

Treatment Options

Treatment depends on the fracture's stability and alignment. Nondisplaced fractures may be managed with immobilization using a cast or brace, followed by gradual weight-bearing and physical therapy. Pain management and activity modification are also key components of care. Severe or unstable fractures may require surgical intervention to restore alignment and stability.

Prognosis and Follow-Up

Most nondisplaced fractures of the medial malleolus heal well with appropriate treatment, though recovery time varies based on the individual's health and fracture severity. Follow-up appointments are necessary to monitor healing and adjust treatment plans. Physical therapy may be recommended to restore strength and mobility.

Complications

Potential complications include delayed healing, nonunion, or malunion of the fracture. Infection, nerve damage, or post-traumatic arthritis may also occur, particularly if the injury involves joint surfaces. Early intervention and adherence to treatment plans can reduce these risks.

Lifestyle & Prevention

• Wear supportive footwear and use ankle braces during high-risk activities.
• Maintain bone health through a balanced diet rich in calcium and vitamin D.
• Avoid activities that increase the risk of falls or ankle injuries.
• Engage in regular exercise to improve balance and muscle strength.

When to Seek Professional Help

Seek immediate medical attention if you experience severe pain, inability to bear weight, visible deformity, or signs of infection (e.g., fever, increased swelling, or redness) after an injury.

Tips for Medical Coders

When coding for S82.55, ensure documentation specifies the nondisplaced nature of the fracture and the left tibia involvement. Verify that the medical record includes details on the fracture's location, alignment, and any associated injuries to support accurate coding.
