Summary
Surgical management for symptomatic bipartite talus, a rare foot condition, involves fragment fusion or excision. Procedures led to symptom improvement and radiographic union in most cases, guiding treatment for this rare foot anomaly.
Area of Science:
- Orthopedic Surgery
- Foot and Ankle Surgery
- Sports Medicine
Background:
- Bipartite talus is a rare foot condition with unknown causes.
- Various surgical treatments have been documented for bipartite talus.
Purpose of the Study:
- To present surgical outcomes for symptomatic bipartite talus.
- To propose a treatment rationale for bipartite talus management.
Main Methods:
- Case series of five symptomatic bipartite talus instances in four male patients.
- Surgical interventions included internal fixation with bone grafting, fragment excision with sub-talar arthrodesis, and tibio-talar-calcaneal fusion.
- Independent assessment and radiographic evaluation were performed.
Main Results:
- One patient with bilateral lesions underwent fixation with bone grafting, with one side failing to unite.
- Another patient with sub-talar osteoarthritis had fragment excision and arthrodesis.
- A third patient with severe hind-foot osteoarthritis underwent tibio-talar-calcaneal fusion.
- The final patient had fragment excision and sub-talar arthrodesis.
- All patients reported symptom improvement or resolution.
- Radiographic union was observed in four cases.
Conclusions:
- A treatment approach involves fragment fusion for larger fragments or excision for smaller ones.
- Associated limited fusion may be necessary for adjacent joint degeneration.
- This strategy aims to improve outcomes for bipartite talus patients.
