Abstract

Objective

To evaluate the efficacy of a computerized cryotherapy protocol on time to surgery, Length of Hospital Stay (LOS), pain control, and complication rates in patients with acute ankle fractures and dislocations, compared to conventional management.

Methods

A single-center comparative analysis was conducted on 428 patients. The intervention group (n=180) received early, regulated computerized cryotherapy via a dedicated boot system according to a standardized protocol. The historical control group (n=248) received conventional management with traditional ice packs and immobilization. Primary outcomes were time to surgery (hours) and LOS (days). Secondary outcomes included pain scores (Visual Analog Scale), opioid consumption (morphine milligram equivalents), postoperative wound complications, and patient satisfaction.
