Summary
Tarsal coalition, affecting less than 1% of people, often impacts the calcaneonavicular and talocalcaneal joints. Surgical correction is frequently needed for persistent foot pain, with excision showing moderate success for calcaneonavicular bars.
Area of Science:
- Orthopedics
- Podiatry
- Pediatric Orthopedics
Background:
- Tarsal coalition is a rare condition affecting foot and ankle motion.
- It commonly involves the calcaneonavicular and talocalcaneal joints.
- Diagnosis is key in adolescent patients with foot pain and limited subtalar motion.
Purpose of the Study:
- To review the prevalence, diagnosis, and treatment outcomes of tarsal coalition.
- To evaluate the effectiveness of surgical intervention for tarsal coalition.
- To discuss long-term results of coalition excision.
Main Methods:
- Literature review of tarsal coalition prevalence and diagnosis.
- Analysis of treatment strategies including conservative and surgical options.
- Assessment of long-term outcomes following surgical excision of tarsal bars.
Main Results:
- Tarsal coalition prevalence is estimated at 1% or less.
- Calcaneonavicular and talocalcaneal joints are most frequently affected.
- Surgical excision offers moderate long-term success for calcaneonavicular bars, but outcomes for subtalar bars are less clear.
Conclusions:
- Early diagnosis and intervention are crucial for managing tarsal coalition.
- Surgical correction is often necessary for persistent symptoms.
- Excision is a viable treatment for calcaneonavicular coalition, while subtalar coalition management requires further investigation.
