Background: Wide Awake Local Anesthesia No Tourniquet (WALANT) uses a mixture of lidocaine and epinephrine for anesthesia and has found great success in hand surgery. At the Philippine Orthopedic Center (POC), we still use local anesthesia along with a tourniquet which gives the patient pain and discomfort at the tourniquet site. This study aims to determine perioperative and post-operative pain, intraoperative bleeding and immediate clinical outcomes of patients using WALANT for surgical anesthesia for carpal tunnel release. Methods: A case series of all patients who underwent carpal tunnel release under WALANT from April 2016 to September 2016 is presented. Those with concomitant trigger finger and de quervain disease which required release on the affected hand were also included. A tourniquet was on standby in case of uncontrollable bleeding. Intraoperative bleeding, pain NRS scores, and return to daily activity were noted. Results: Thirteen patients were included in the study; 3 were male, 10 were female. Mean age was 58 years, Mean surgical time was 15 minutes. Twelve were reported to have “some bleeding” and one was reported to have “bleeding but was still manageable”. None of the surgeries were totally bloodless or had too much bleeding that necessitated a tourniquet. Pain NRS scores during injection of local anesthesia had a mean of 2. None of the patients felt pain during and immediately after the surgery. Average time return to daily activity was 6 days. No complications were noted. Conclusions: Patients included in the study who underwent carpal tunnel release under WALANT did not experience pain associated with a tourniquet. Visualization of the field was adequate enough for the surgeons to do the surgery without the need for a tourniquet and with no associated complications.

Background: Closed reduction and internal fixation (CRIF) of closed hand fractures in the main operating room (OR) is much more expensive than outside of the OR. However, there is a reluctance to fix fractures out of the OR due to the perceived increase in infections. Our goal was to prospectively analyze the infection rates of performing CRIF of closed metacarpal and phalangeal fractures in these two settings. Methods: A multicenter prospective analysis of patients undergoing CRIF of metacarpal or phalangeal fractures inside or outside the OR was performed. Demographic data, injury characteristics, surgery information and postoperative infectious complications were recorded, including cellulitis, frank pus, and osteomyelitis. Results: The study involved 1042 patients with a total of 2265 Kirschner-wires (K-wires). Infection rates were not statistically higher in the 719 patients who had CRIF outside of the OR (cellulitis 2.5%, frank pus 1.4%) compared with the 323 patients with CRIF in the OR group (cellulitis 3.4%, frank pus 2.5%). The OR group had a longer time to operation and a longer procedure time, but a shorter time with the K-wires in place. Conclusion: K-wire fixation of closed hand fractures outside of the OR under field sterility is safe because it does not increase infectious complications compared to CRIF in the main OR under full sterility.
