Patient randomization will be performed using computerized random number table, in which patient will be randomly allocated in a ratio of 1：1 to receive one of the two assigned blocks.

Group A (n = 43) will receive Femoral nerve Block with 15 mL of 0.25% bupivacaine).

Group B (n = 43) will receive Fascia iliaca compartment block with 30 mL of 0.25% bupivacaine).

Depending on the allotted group, patients will receive the block under the guidance of ultrasound in the Operation Theatre under all aseptic precautions.

Effect will be checked by pin prick on anterior part of thigh at every 2 min interval.  VAS (Visual Analogue Scale) Score will be recorded before the block and immediately after the block at every 1 min interval upto 15 min until VAS is <3. The time taken to achieve VAS <3 will be noted. When VAS Score is achieved<3 under all aseptic precautions SAB will be given in sitting position in L3-L4 space using 0.5% hyperbaric Bupivacaine 12.5mg +25mcg of fentanyl using 25 gauze quinke’s needle. When adequate sensory and motor blockade will be achieved, surgery will be started. Intraoperative parameters such as Heart Rate, SBP, DBP, MAP andSpo2 will be monitored according to proforma.

When surgery will  complete patient will be shifted to PACU. Inj. Tramadol  100 mg will be given as rescue analgesia. Time for the need of first rescue  analgesia will be noted. This time will be calculated from VAS<3 after the block to request of first rescue analgesia by patient at VAS >3.VAS Score will  be assessed at hourly interval for first 6 hrs., 2 hrly interval for 12hrs, 4 hrly interval for 24 hrs.Total dose of Tramadol required in 24hrs will be noted. Anesthesiologist Satisfaction Score, and Patient’s satisfaction score will be  assessed.Side effect if develop will be noted and managed accordingly.
