NCT02950558

Brief Summary

This pilot study will test the hypothesis that prolonged regional peripheral nerve block will reduce development of chronic pain in patients undergoing surgery for ankle fracture compared to standard of care. Subjects will be followed for one year.

Outcome Measures

Primary Outcomes (1)

  • Pain Score at 12 Months - Experimental Group vs. Control Group

    Patients will complete Self-Administered Foot and Ankle Questionnaire (SEFAS) at 12 months post surgery. 0 = worst possible pain and function, 48 = no pain or dysfunction. Higher scores indicate a better outcome.

    at 12 months post surgery

Secondary Outcomes (4)

  • Pain Score at 2 Weeks - Experimental Group vs. Control Group

    at 2 weeks post surgery

  • Pain Score at 3 Months - Experimental Group vs. Control Group

    at 3 months post surgery

  • Pain Score at 6 Months - Experimental Group vs. Control Group

    at 6 months post surgery

  • Incidence of Chronic Ankle Pain Diagnoses - Experimental Group vs. Control Group

    at 1 year post surgery

Limitations and Caveats

A problem encountered was that only 1 of the 6 subjects in the pump group received the full 5 days of treatment. The others discontinued using the pump early, primarily due to problems with catheter dislodgement/leakage. As specified in the statistical analysis plan, these subjects were all analyzed with intent-to-treat protocol and are included in the pump group data presented. Also, by chance, the distribution of males and females between the group was quite uneven.
