ICD-10: S93.149

The ICD-10 code S93.149 refers to the subluxation of the metatarsophalangeal joint of unspecified toe(s). This condition is categorized under the broader classification of dislocations and sprains, specifically focusing on the subluxation aspect, which is a partial dislocation of a joint.

Clinical Description

Definition of Subluxation

Subluxation is defined as a partial dislocation where the joint surfaces are misaligned but still maintain some contact. In the case of the metatarsophalangeal joint, which connects the metatarsal bones of the foot to the proximal phalanges of the toes, this condition can lead to pain, swelling, and impaired function of the affected toe(s) [2][4].

Symptoms

Patients with a subluxation of the metatarsophalangeal joint may experience:
- Pain: Often localized around the joint, which may worsen with movement or weight-bearing activities.
- Swelling: Inflammation around the joint area is common, leading to visible swelling.
- Limited Range of Motion: Difficulty in moving the affected toe(s) due to pain and instability.
- Deformity: In some cases, the toe may appear misaligned or out of its normal position.

Causes

Subluxation of the metatarsophalangeal joint can result from 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 subluxations.
- Improper Footwear: High heels or ill-fitting shoes can contribute to abnormal stress on the toes, increasing the risk of subluxation.

Diagnosis

Diagnosis typically involves a thorough clinical examination, where a healthcare provider assesses the joint's stability, range of motion, and any associated symptoms. Imaging studies, such as X-rays, may be utilized to confirm the diagnosis and rule out complete dislocations or fractures [1][3].

Treatment

Treatment for a subluxation of the metatarsophalangeal joint may include:
- Rest and Ice: To reduce swelling and pain.
- Immobilization: Using splints or buddy taping to stabilize the affected toe(s).
- Physical Therapy: To strengthen the surrounding muscles and improve joint stability.
