Efficacy of Intraoperative Periarticular Injections in Hip Fracture Hemiarthroplasty

Patients in the periarticular injection group were administered a 100 mL periarticular solution comprising 200 mg of bupivacaine (40 mL), 60 mg of ketorolac (2 mL), 8 mg of dexamethasone (2 mL), 2 mg of 1:1000 epinephrine (2 mL), and standard saline solution (54 mL). This solution was prepared in two 50 mL syringes. The first syringe containing 50 mL of the cocktail was injected into the capsule and gluteal muscles prior to femoral stem insertion. Following joint capsule closure, the second syringe containing 50 mL of the periarticular injection cocktail was infiltrated into the fascia lata muscle, subcutaneous tissue, and wound layers.

The control group received the conventional treatment protocol.
