Realignment Calcaneal Osteotomy for Bilateral Complete Talocalcaneal Synostosis: A Case Report

Area of Science:

• Orthopedics
• Pediatric Orthopedics
• Foot and Ankle Surgery

Background:

• Talocalcaneal synostosis is a rare congenital condition involving incomplete segmentation of tarsal bones.
• Differentiating it from talocalcaneal coalition, the most common tarsal coalition, can be difficult, especially with large bone bridges.
• Complete talocalcaneal synostosis is exceptionally rare, with limited literature on clinical outcomes and surgical interventions.

Observation:

• A 15-year-old female presented with bilateral complete talocalcaneal synostosis.
• The patient also exhibited a heel varus deformity.
• This condition presented diagnostic challenges due to its rarity and potential overlap with talocalcaneal coalition.

Findings:

• The patient underwent a lateral sliding calcaneal osteotomy for hindfoot realignment.
• This surgical intervention yielded positive clinical results.
• The procedure effectively addressed the heel varus deformity associated with the synostosis.

Implications:

• Lateral sliding calcaneal osteotomy is a viable surgical option for correcting hindfoot deformities in cases of complete talocalcaneal synostosis.
• This case expands the understanding of surgical management and outcomes for this rare condition.
• Further research into operative methods and long-term outcomes for symptomatic talocalcaneal synostosis is warranted.
