The investigators will be comparing ultrasound-guided (USG) ankle block and anatomic landmark-guided (ALG) ankle block to determine which of these procedures is better in surgical anesthesia and in postoperative pain relief.

Condition Intervention
Analgesia Drug: Bupivacaine

Study Type: Observational
Study Design: Observational Model: Case Control
Time Perspective: Prospective

Further study details as provided by Hillel Yaffe Medical Center:

Primary Outcome Measures:
  • Surgical Anesthesia Sufficient [ Time Frame: Thirty minutes ]
    Sufficiency of surgical anesthesia will be determined by the presence of a complete sensory or motor block. If general anesthesia needs to be added to achieve operative analgesia, the surgical block will not be deemed sufficient.

  • Post-operative Pain Relief [ Time Frame: Twenty-four hours ]
    Intensity of post-operative pain will be measured by a numerical scale from 0-10 by the patient

Estimated Enrollment: 100
Study Start Date: December 2012
Estimated Study Completion Date: December 2014
Estimated Primary Completion Date: December 2014 (Final data collection date for primary outcome measure)
