Summary: Arthroscopic Subtalar Arthrodesis technique is a simple and fast, which can be used in cases of osteoarthritis even in patients with a very small joint space. The clinical outcome found was quite promissing.


Introduction

Subtalar joint arthrodesis can be performed arthroscopically through two hindfoot portals with the patient in the prone position.
This approach allows a simple way to achieve arthrodesis in patients with symptomatic subtalar osteoarthritis

Material And Methods

The patients studied underwent subtalar arthrodesis between January 2011 and December 2011, with a minimum follow-up of 12 months and maximum 18 months.
The sample is composed of 27 patients, with 83.3% female and 16.7% were male, with an average age of 53.8 years.
7 patients had a history of calcaneus fracture and 20 degenerative osteoarthritis.
Arthroscopy was performed with joint distraction with trocar introduced through the sinus tarsi and with cruentation of the articular surfaces using bone shaver. There were always placed 2 uncannulated screws, self-compressive, with fluoroscopic control.
None of the patients needed corrective osteotomy action.
The patients were evaluated for functional AOFAS hindfoot score and radiologically evaluation with x-ray.

Results

All patients had arthrodesis achieved with improvement of symptoms with clinical and radiological healing of the arthrodesis between 8 and 12 weeks.
The average AOFAS score was 80 ± 4 points.

Discussion

This arthroscopic subtalar arthodesis is a simple technique with high consolidation rate, without risk of cutaneous necrosis.
Positioning the patient in the prone position facilitates the surgical technique.
The use of uncannulated screws seem to show quite good compression capacity.

Conclusion

The subtalar arthroscopic fusion technique is a simple and fast, which can be used in cases of osteoarthritis even in patients with a very small joint space. The clinical outcome found was quite promissing.
This procedure does not imply prolonged hospitalization and has very few complications.
