S72.435H Nondisplaced fracture of medial condyle of left femur, subsequent encounter for open fracture type I or II with delayed healing

Name of the Condition

• Nondisplaced fracture of medial condyle of left femur, subsequent encounter for open fracture type I or II with delayed healing

Summary

This condition involves a nondisplaced fracture of the medial condyle, the inner rounded projection of the left femur at the knee joint. The fracture is classified as open (type I or II), meaning the skin is breached but the wound is typically small and clean. Nondisplacement indicates the bone fragments remain aligned, though the open nature of the fracture increases infection risk. The injury affects knee stability and function, potentially causing pain, swelling, and impaired mobility. This is a subsequent encounter, indicating ongoing care for a fracture that has not healed as expected within the typical timeframe.

Causes

High-impact trauma, such as falls, motor vehicle accidents, or direct blows to the knee. Sports injuries or physical altercations involving the thigh. Stress fractures from repetitive overuse or strenuous activity.

Risk Factors

• Advanced age, which may lead to decreased bone density.
• Osteoporosis or other bone-weakening conditions.
• Participation in high-risk activities or contact sports.
• Prior history of femur fractures or bone disorders.
• Poor blood supply to the fracture site.
• Inadequate initial treatment or immobilization.

Symptoms

• Severe pain localized to the inner knee or thigh.
• Swelling, bruising, or visible deformity around the knee.
• Inability to bear weight or move the knee joint properly.
• Possible numbness or tingling if nerves are involved.
• Open wound at the fracture site (type I or II).
• Persistent pain or instability beyond the expected healing period.

Diagnosis

Physical examination to assess pain, swelling, and limb alignment. Imaging studies, such as X-rays or CT scans, to confirm the fracture type, location, and healing status. Additional tests, like MRI, if soft tissue damage or subtle fractures are suspected. Evaluation of the open wound to determine its type and risk of infection. Assessment of healing progress to identify delayed union.

Treatment Options

• Immobilization with a cast or brace to stabilize the fracture.
• Wound care for the open fracture to prevent infection.
• Pain management with medications or physical therapy.
• Surgical intervention if the fracture shows no signs of healing or if the wound requires debridement.
• Bone stimulation therapies to promote healing in cases of delayed union.

Prognosis and Follow-Up

Prognosis depends on the severity of the fracture, the effectiveness of treatment, and the patient’s overall health. Delayed healing may prolong recovery, requiring extended follow-up and adjustments to the treatment plan. Regular monitoring with imaging is necessary to assess progress. Most patients eventually regain function, but some may experience long-term stiffness or weakness.

Complications

• Infection at the open fracture site.
• Nonunion or malunion of the fracture.
• Chronic pain or arthritis in the knee joint.
• Nerve or blood vessel damage.
• Limited mobility or functional impairment.

Lifestyle & Prevention

• Avoid high-impact activities until fully healed.
• Follow a balanced diet rich in calcium and vitamin D to support bone health.
• Use protective gear during sports or high-risk activities.
• Maintain a healthy weight to reduce stress on the knee joint.
• Engage in low-impact exercises, such as swimming, to preserve mobility.

When to Seek Professional Help

Seek immediate medical attention if you experience severe pain, swelling, or deformity after an injury. Contact your healthcare provider if you notice signs of infection, such as redness, warmth, or pus at the wound site. Follow up regularly with your provider to monitor healing progress and address any concerns.

Tips for Medical Coders

Document the fracture type (open, type I or II), the encounter type (subsequent), and the presence of delayed healing. Ensure clinical notes specify the fracture’s alignment (nondisplaced) and the affected side (left femur). Include details about wound care, imaging results, and any interventions related to delayed healing to support accurate coding.
