A local anesthesia without tourniquet for distal fibula hardware removal after open reduction and internal fixation: the safe use of epinephrine in the foot. A randomized clinical study
Vol 32, Issue 6S1, 2018
Abstract
Hardware removal after surgical treatment fracture is one of the most common procedures in orthopaedic daily activity. A percentage from 14.5 to 21 of total removal involves the ankle joint. Trying to reduce the important socio-economic impact of this surgical procedure, we thought to perform it using the Wide Awake Local Anaesthesia Without Tourniquet (WALANT), a particular technique presented by D. Lalonde that associated a local anaesthetic drug with epinephrine in order to obtain an effective haemostatic effect despite the lack of a tourniquet. Nowadays, the WALANT efficiency and safety in hand surgery is widely demonstrated in literature but there are no data about its use in lower limb extremity surgeries. Authors performed a randomized study with 60 patients whom underwent distal fibula hardware removal between 2014 and 2016; they were divided into two groups: Group A under loco-regional anaesthesia with tourniquet and Group B under WALANT. We did not find significant differences in term of maximum pain level felt during the anaesthesiologic and surgical procedure. However, the use of WALANT significantly reduced post-operative pain levels. The WALANT procedures also reduced the number of hospitalization days. No differences in term of post-operative complication rates were found. In conclusion, the WALANT can be considered as a suitable option for distal fibula hardware removal in selected patients; it shows important clinical and economic advantages compared to the traditional loco-regional anaesthesia with tourniquet. This study also lays the foundation for the use of the WALANT beyond the field of hand surgery only.
