Subluxation of the tarsometatarsal joint, specifically coded as S93.321 in the ICD-10 classification, refers to a partial dislocation of the joints connecting the tarsal bones to the metatarsals in the foot. This condition can lead to pain, instability, and functional impairment, necessitating a comprehensive treatment approach. Below, we explore standard treatment strategies for managing this injury.

Initial Assessment and Diagnosis

Before treatment can begin, a thorough assessment is essential. This typically includes:

• Clinical Examination: A healthcare provider will assess the foot for swelling, tenderness, and range of motion. They may also check for any visible deformities.
• Imaging Studies: X-rays are commonly used to confirm the diagnosis and rule out complete dislocations or fractures. In some cases, MRI may be utilized to evaluate soft tissue injuries associated with the subluxation[1].

Conservative Treatment Approaches

Most cases of tarsometatarsal joint subluxation can be managed conservatively, especially if the injury is not severe. Standard conservative treatment options include:

1. Rest and Activity Modification

• Patients are advised to avoid weight-bearing activities to allow the joint to heal. Crutches or a walking boot may be recommended to minimize stress on the foot[1].

2. Ice Therapy

• Applying ice to the affected area can help reduce swelling and alleviate pain. It is typically recommended to ice the area for 15-20 minutes every few hours during the initial days post-injury[1].

3. Compression and Elevation

• Compression bandages can help control swelling, while elevating the foot above heart level can further assist in reducing edema[1].

4. Pain Management

• Over-the-counter nonsteroidal anti-inflammatory drugs (NSAIDs), such as ibuprofen or naproxen, may be prescribed to manage pain and inflammation[1].

5. Physical Therapy

• Once the acute pain subsides, physical therapy may be initiated to restore range of motion, strength, and stability. This often includes exercises focused on ankle mobility, proprioception, and strengthening the surrounding musculature[1][2].

Surgical Treatment Options

In cases where conservative management fails or if the subluxation is severe, surgical intervention may be necessary. Surgical options can include:

1. Open Reduction and Internal Fixation (ORIF)

• This procedure involves realigning the bones and securing them with hardware, such as screws or plates, to stabilize the joint[2].

2. Arthrodesis

• In chronic cases or when there is significant joint instability, fusion of the tarsometatarsal joint may be considered to provide stability and alleviate pain[2].

Rehabilitation and Recovery

Post-treatment rehabilitation is crucial for a successful recovery. This phase typically includes:

• Gradual Return to Activity: Patients are guided on how to progressively return to normal activities, including weight-bearing exercises and sports, based on their recovery progress.
• Continued Physical Therapy: Ongoing therapy may be necessary to ensure full recovery and prevent future injuries. This can include balance training and functional exercises tailored to the patient's needs[1][2].

Conclusion

The management of subluxation of the tarsometatarsal joint (ICD-10 code S93.321) typically begins with conservative treatment strategies, focusing on rest, ice, compression, and physical therapy. Surgical options are reserved for more severe cases or when conservative measures fail. A structured rehabilitation program is essential for restoring function and preventing recurrence. As always, treatment should be tailored to the individual patient's needs and the specifics of their injury.
