Brief Summary:
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 or disease Intervention/treatment

Drug Information available for: Bupivacaine

Group/Cohort Intervention/treatment
Patients receiving Ultrasound-guided Ankle Block
Drug: Bupivacaine
Patients receiving Anatomic Landmark-guided Ankle Block
Drug: Bupivacaine

Primary Outcome Measures :
  1. 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.

  2. 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
