ICD-10: M77.40

Metatarsalgia, classified under ICD-10 code M77.40, refers to pain and discomfort in the metatarsal region of the foot, specifically without a specified cause. This condition is characterized by pain in the ball of the foot, which can result from various factors, including overuse, improper footwear, or underlying medical conditions.

Clinical Description

Definition

Metatarsalgia is a term used to describe pain in the metatarsal area, which consists of the five long bones in the foot that connect the toes to the midfoot. The pain is typically localized to the area just before the toes, often exacerbated by activities that put pressure on the forefoot, such as running or standing for extended periods[1][2].

Symptoms

Patients with metatarsalgia may experience:
- Sharp, aching, or burning pain in the ball of the foot.
- Pain that worsens with activity and improves with rest.
- Swelling or inflammation in the affected area.
- A feeling of having a pebble in the shoe or discomfort when walking[3][4].

Causes

The causes of metatarsalgia can be multifactorial, including:
- Biomechanical Issues: Abnormal foot mechanics, such as high arches or flat feet, can lead to uneven weight distribution and increased pressure on the metatarsals.
- Footwear: Wearing shoes that are too tight, high-heeled, or lack proper support can contribute to the development of metatarsalgia.
- Injury: Trauma to the foot, such as fractures or sprains, can lead to pain in the metatarsal region.
- Medical Conditions: Conditions like arthritis, Morton’s neuroma, or diabetes can also predispose individuals to metatarsalgia[5][6].

Diagnosis

Diagnosis of metatarsalgia typically involves:
- Clinical Evaluation: A thorough history and physical examination to assess pain location, duration, and exacerbating factors.
- Imaging Studies: X-rays or MRI may be utilized to rule out fractures, arthritis, or other structural abnormalities[7][8].

Treatment

Treatment options for metatarsalgia may include:
- Conservative Management: Rest, ice application, and anti-inflammatory medications to reduce pain and swelling.
- Footwear Modifications: Switching to shoes with a wider toe box and better arch support can alleviate pressure on the metatarsals.
- Orthotics: Custom insoles or orthotic devices can help correct biomechanical issues and redistribute weight more evenly across the foot.
- Physical Therapy: Exercises to strengthen foot muscles and improve flexibility may be recommended[9][10].
