Results of surgical treatment of tarsal tunnel syndrome.

BACKGROUND

The aim of our study is to evaluate retrospectively the prognostic factors affecting the final outcome of surgical treatment of tarsal tunnel syndrome.

MATERIAL AND

METHODS

Surgical decompression were performed on 31 patients. All patients had EMG and anesthetic test confirmation. The results were evaluated according to VAS scale and modified AOFAS score. Follow-up was after 12 months.

RESULTS

22 patients received very good or good (71%), 7 satisfactory (22%), 2 poor (7%) results in the subjective and objective patient's assessment. The outcomes decreased from 5.19 (SD 1.01) points to 1.19 (SD 0.83) points according to VAS scale, and modified AOFAS increased from 31.77 (SD 9.08) points to 57.58 (SD 9.90). Patients with diagnosed cause, short period of time between onset of disease till surgery, and positive Tinel's sign achieved the best results.

CONCLUSION

Etiology of the tarsal tunnel syndrome has influence on the results. Immediate diagnosis and short period between occurrences of symptoms in surgical treatment improves the outcomes. Tinel's sign may be used as a prognostic factor.
