ICD-10: S90.445

The ICD-10 code S90.445 specifically refers to "External constriction, left lesser toe(s)." This code falls under the broader category of S90, which encompasses various superficial injuries of the toes. Here’s a detailed clinical description and relevant information regarding this condition.

Clinical Description

Definition

External constriction of the toe occurs when a foreign object, such as a hair, string, or other material, wraps around the toe, leading to compression. This condition can result in pain, swelling, and potential ischemia (reduced blood flow) if not addressed promptly. The left lesser toe(s) specifically refers to the smaller toes on the left foot, typically the second, third, fourth, and fifth toes.

Symptoms

Patients with external constriction of the left lesser toe(s) may present with the following symptoms:
- Pain: Localized pain at the site of constriction, which may worsen with movement.
- Swelling: The affected toe may appear swollen due to inflammation and fluid accumulation.
- Discoloration: The toe may exhibit changes in color, such as redness or a bluish tint, indicating compromised blood flow.
- Numbness or Tingling: Patients may experience altered sensation in the affected toe due to nerve compression.

Causes

The primary cause of external constriction is the presence of a tight band or object around the toe. Common sources include:
- Hair: Often seen in children, where hair wraps around a toe, leading to constriction.
- String or Thread: Accidental entanglement of threads from clothing or other materials.
- Tight Footwear: Shoes that are too tight can also contribute to constriction, although this is less common for specific toes.

Diagnosis

Diagnosis of external constriction of the left lesser toe(s) typically involves:
- Clinical Examination: A thorough physical examination to assess the toe's condition, including checking for signs of constriction, swelling, and discoloration.
- Patient History: Gathering information about the onset of symptoms, potential causes (e.g., recent haircuts, activities involving string), and any previous occurrences.

Treatment

Treatment for external constriction of the left lesser toe(s) focuses on relieving the constriction and addressing any complications:
- Removal of Constricting Material: The first step is to carefully remove any hair, string, or other materials causing the constriction.
