S93.325 Dislocation of tarsometatarsal joint of left foot

Name of the Condition

• Dislocation of tarsometatarsal joint of left foot

Summary

This condition involves the complete displacement of the tarsometatarsal joint in the left foot, where the tarsal bones and metatarsal bones lose their normal alignment. It typically results in pain, swelling, and impaired weight-bearing function due to joint instability.

Causes

Trauma, such as falls, sports injuries, or direct impacts to the foot, is the primary cause. Twisting or rotational forces applied to the foot can lead to joint displacement. High-impact events or sudden movements may also result in dislocation of the tarsometatarsal joint.

Risk Factors

• Participation in high-impact sports or activities with sudden directional changes.
• Previous foot injuries or joint instability.
• Wearing footwear that lacks proper support or stability.
• Uneven terrain or poor surface conditions.

Symptoms

• Pain and swelling in the midfoot area.
• Inability to bear weight or walk normally.
• Visible deformity or misalignment of the foot.
• Bruising or discoloration around the injured joint.
• Tenderness to touch or pressure.

Diagnosis

Diagnosis involves a physical examination to assess pain, swelling, and joint stability. Imaging tests, such as X-rays, are used to confirm displacement and rule out fractures. CT or MRI may be used to evaluate soft tissue or ligament damage.

Treatment Options

Initial treatment focuses on immobilization of the foot with a cast or boot, rest, ice, compression, and elevation. Severe cases may require closed reduction or surgical intervention to restore joint alignment. Physical therapy is often recommended during recovery to restore strength and function.

Prognosis and Follow-Up

Prognosis depends on the severity of the injury and adherence to treatment. Most patients recover with proper immobilization and rehabilitation, though some may experience long-term stiffness or instability. Follow-up appointments are necessary to monitor healing and adjust treatment plans as needed.

Complications

• Chronic pain or instability in the midfoot.
• Post-traumatic arthritis due to joint damage.
• Nerve or blood vessel injury in severe cases.
• Delayed healing or nonunion if treatment is inadequate.

Lifestyle & Prevention

• Wear supportive footwear during physical activities.
• Avoid uneven surfaces or high-impact movements that strain the foot.
• Strengthen foot and ankle muscles through targeted exercises.
• Use protective gear during sports to reduce injury risk.

When to Seek Professional Help

Seek immediate medical attention if you experience severe foot pain, visible deformity, or inability to bear weight after an injury. Persistent swelling, bruising, or difficulty walking should also prompt a clinical evaluation.

Tips for Medical Coders

Document the laterality (left foot) and the nature of the injury (dislocation) clearly. Ensure clinical notes specify the affected joint and any associated trauma or mechanism of injury. Code S93.325 is specific to dislocation of the tarsometatarsal joint of the left foot; verify documentation aligns with the code's definition to support accurate assignment.
