ICD-10: S93.323

The ICD-10 code S93.323 refers to a subluxation of the tarsometatarsal joint of an unspecified foot. This code is part of the broader category of codes that address dislocations and sprains, specifically focusing on the tarsometatarsal joint, which is crucial for foot stability and movement.

Clinical Description

Definition of Subluxation

A subluxation is defined as a partial dislocation where the joint surfaces are misaligned but still maintain some contact. This condition can lead to pain, swelling, and impaired function of the affected joint. In the case of the tarsometatarsal joint, which connects the tarsal bones to the metatarsals, subluxation can significantly affect a person's ability to walk or bear weight.

Anatomy of the Tarsometatarsal Joint

The tarsometatarsal joint consists of the five metatarsal bones and the distal tarsal bones (specifically, the cuboid and the three cuneiform bones). This joint plays a vital role in the foot's biomechanics, allowing for flexibility and stability during movement. Disruption in this area can lead to altered gait patterns and increased risk of further injury.

Causes of Subluxation

Subluxation of the tarsometatarsal joint can occur due to various factors, including:
- Trauma: Acute injuries from falls, sports, or accidents can lead to joint instability.
- Chronic Conditions: Conditions such as arthritis or ligamentous laxity may predispose individuals to subluxation.
- Improper Footwear: Wearing shoes that do not provide adequate support can contribute to joint misalignment.

Symptoms

Patients with a tarsometatarsal joint subluxation may experience:
- Pain: Localized pain at the top of the foot or in the arch.
- Swelling: Inflammation around the joint area.
- Limited Range of Motion: Difficulty in moving the toes or foot.
- Instability: A feeling of the foot giving way during weight-bearing activities.

Diagnosis and Treatment

Diagnosis

Diagnosis typically involves a thorough clinical examination, patient history, and imaging studies such as X-rays or MRI to assess the extent of the subluxation and rule out fractures.
