T84.117A Breakdown (mechanical) of internal fixation device of bone of left lower leg, initial encounter

ICD10CM code

#### Name of the Condition
- Breakdown (mechanical) of internal fixation device of bone of left lower leg, initial encounter
- ICD-10 Code: T84.117A

#### Summary
This condition involves the failure or malfunction of an internal fixation device, such as a plate, rod, or screw, that was surgically implanted to stabilize a fracture or bone in the left lower leg. The initial encounter denotes the first time the patient is being assessed for this specific issue.

#### Causes
- Normal wear and tear over time
- Repetitive stress or excessive load on the leg
- Trauma or injury to the leg
- Improper surgical installation

#### Risk Factors
- Previous leg surgeries with internal fixation
- Engaging in high-impact sports or activities
- Osteoporosis or weakened bones
- Advanced age leading to bone weakness

#### Symptoms
- Pain or discomfort in the lower leg
- Swelling or inflammation in the affected area
- Instability or inability to bear weight on the leg
- Visible or palpable abnormalities near the site of implantation

#### Diagnosis
- Physical examination assessing the affected area
- Imaging techniques such as X-rays or MRIs to visualize the breakdown
- Patient medical history review confirming prior surgical interventions

#### Treatment Options
- **Revision surgery:** Replacing or repairing the broken device.
- **Pain management:** Medications to relieve discomfort.
- **Physical therapy:** To improve mobility post-repair.
- **Rest and immobilization:** To prevent further injury.

#### Prognosis and Follow-Up
- Generally favorable with appropriate intervention and no severe complications.
- Regular follow-up appointments are crucial to monitor healing and prevent recurrences.

#### Complications
- Infection at the site of implantation
- Non-union or delayed healing of the bone
- Potential for additional surgeries if not resolved

#### Lifestyle & Prevention
- Avoid repetitive stress on the affected leg post-recovery
- Engage in low-impact exercises to maintain bone health
- Adequate calcium and vitamin D intake to support bone strength

#### When to Seek Professional Help
- Sudden increase in pain or swelling
- Loss of function or mobility in the leg
- Signs of infection such as redness, warmth, or discharge
