M89.672

Clinical Causes: Previous poliomyelitis infection, especially if it was severe or involved muscles supporting the ankle and foot Post-viral nerve damage leading to altered biomechanics in the affected limb Muscle weakness or paralysis resulting in abnormal gait and stress on bones and joints Age-related degeneration of the affected joints after initial recovery Compensatory changes in gait causing additional strain on the ankle and foot bones

Key Symptoms: Persistent pain or discomfort in the left ankle and foot Swelling or inflammation in the affected area Reduced range of motion or stiffness Muscle weakness or fatigue in the lower limb Altered gait or walking difficulties Numbness or tingling sensations due to nerve involvement Development of deformities or abnormal foot positioning over time

Diagnosis Path: Medical history review focusing on prior poliomyelitis infection and recent symptoms Physical examination assessing joint mobility, muscle strength, and deformities Imaging studies such as X-rays to evaluate bone structure and joint integrity Additional tests like MRI or CT scan if soft tissue or nerve damage is suspected Assessment by specialists in orthopedics or neurology to determine the extent of musculoskeletal involvement

Treatment Protocols: Physical therapy to strengthen muscles, improve joint flexibility, and promote proper gait Orthotic devices such as braces or custom insoles to provide support and alleviate strain Pain management strategies including medications or topical treatments Surgical intervention in severe cases for realignment, stabilization, or correction of deformities Assistive devices like canes or walkers to enhance mobility and safety Lifestyle modifications, including weight management and activity adjustments, to reduce joint stress Regular follow-up to monitor progression and address new symptoms
