Purpose: To assess moderate-term outcomes of silastic joint replacements of the first metatarsophalangeal joint.

Method: The thirty-two patients (37 feet) that had silastic implants inserted were reviewed at an average of 2 years and 4 months (ranging 7 months to 5 years and 4 months). The mean patient age was 63 years. These patients answered a subjective questionnaire, had their feet examined clinically and radiographically and a pre-operative and post-operative AOFAS score was calculated for each.

Results: The follow-up assessment revealed that every patient described that their pain had decreased after surgery and 17 feet (46%) were completely pain free. There was a significant improvement in patients’ subjective pain scores after surgery (t value = < 0.0001). Pre-operatively, the mean pain score for all 37 feet was 8.14, whereas post-operative the mean pain score was 1.32. The mean AOFAS score before surgery was 39.97. This increased to a mean score of 87.40 after surgery (P = < 0.0001). This again is a significant improvement. No patient was dissatisfied with the outcome with their surgery.

Conclusion: These moderate term results are encouraging, with good subjective and objective results. However, long-term follow-up will be required to assess the longevity of this implant.
