Is Non-Weight-Bearing Necessary? (INWN) is a pragmatic multicentre randomised controlled trial comparing immediate protected weight-bearing (IWB) with non-weight-bearing cast immobilisation (NWB) following ankle fracture fixation (ORIF). This trial compares; functional outcomes, complication rates and performs an economic analysis to estimate cost-utility. IWB within 24hrs was compared to NWB, following ORIF of all types of unstable ankle fractures. Skeletally immature patients and tibial plafond fractures were excluded. Functional outcomes were assessed by the Olerud-Molander Ankle Score (OMAS) and RAND-36 Item Short Form Survey (SF-36) taken at regular follow-up intervals up to one year. A cost-utility analysis via decision tree modelling was performed to derive an incremental cost effectiveness ratio (ICER). A standard gamble health state valuation model utilising SF-36 scores was used to calculate Quality Adjusted Life Years (QALYs) for each arm. We recruited 160 patients (80 per arm), aged 15 to 94 years (M = 45.5), 54% female. Complication rates were similar in both groups. IWB demonstrated a consistently higher OMAS score, with significant values at 6 weeks (MD=10.4, p=0.005) and 3 months (MD 12.0, p=0.003). Standard gamble utility values demonstrated consistently higher values (a score of 1 equals perfect health) with IWB, significant at 3 months (Ẋ = 0.75 [IWB] / 0.69 [NWB], p=0.018). Cost-utility analysis demonstrated NWB is €798.02 more expensive and results in 0.04 fewer QALYs over 1 year. This results in an ICER of −€21,682.42/QALY. This negative ICER indicates cost savings of €21,682.42 for every QALY (25 patients = 1 QALY gain) gained implementing an IWB regime. IWB demonstrates a superior functional outcome, greater cost savings and similar complication rates, compared to NWB following ankle fracture fixation.
The purpose of this trial is to investigate the safety and efficacy of immediate weight-bearing (IWB) and range of motion exercise regimes following ORIF of unstable ankle fractures with a particular focus on functional outcomes and complication rates. A pragmatic randomised controlled multicentre trial, comparing IWB in a walking boot and ROM within 24 hours versus NWB and immobilisation in a cast for six weeks, following ORIF of all types of unstable adult ankle fractures. The exclusion criteria are skeletal immaturity and tibial plafond fractures. The primary outcome measure is the functional Olerud-Molander Ankle Score (OMAS). Secondary outcomes include wound infection, displacement of osteosynthesis, the full arc of ankle motion, RAND-36 Item Short Form Survey (SF-36) scoring, time to return to work and postoperative hospital length of stay.Abstract

Postoperative management regimes vary following open reduction and internal fixation of unstable ankle fractures. There is an evolving understanding that poorer outcomes could be associated with non-weight bearing protocols and immobilisation. Traditional non-weight bearing cast immobilisation may prevent loss of fixation, and this practice continues in many centres. The aim of this systematic review and meta-analysis is to compare the complication rate and functional outcomes of early weight-bearing (EWB) versus late weight-bearing (LWB) following open reduction and internal fixation of ankle fractures. We performed a systematic review with a meta-analysis of controlled trials and comparative cohort studies. MEDLINE (via PubMed), Embase and the Cochrane Library electronic databases were searched inclusive of all date up to the search time. We included all studies that investigated the effect of weight-bearing following adults ankle fracture fixation by any means. All ankle fracture types, including isolated lateral malleolus fractures, isolated medial malleolus fractures, bi-malleolar fractures, tri-malleolar fractures and Syndesmosis injuries, were included. All weight-bearing protocols were considered in this review, i.e. immediate weight-bearing (IMW) within 24 hours of surgery, early weight-bearing (EWB) within three weeks of surgery, non-weight-bearing for 4 to 6 weeks from the surgery date (or late weight-bearing LWB). Studies that investigated mobilisation but not weight-bearing, non-English language publications and tibial Plafond fractures were excluded from this systematic review. We assessed the risk of bias using ROB 2 tools for randomised controlled trials and ROBINS-1 for cohort studies. Data extraction was performed using Covidence online software and meta-analysis by using RevMan 5.3.Introduction and Objective
Materials and Methods
Wide awake local anaesthetic no tourniquet (WALANT) is being used for a wide variety of hand and wrist surgery. It has recently been used in distal radius fracture fixation. The purpose of this systematic review and meta-analysis was to assess the effectiveness of the WALANT technique in open reduction internal fixation. Pubmed, Embase, and Scopus databases were searched on 02/03/21 with the following search terms: radius, WALANT, local anesthetic, wide awake surgery. The primary outcome measure was conversion to general anaesthetic and mean intra-operative visual analogue scale (VAS) pain scores. Secondary measures were operative times, mean intraoperative blood loss, post-operative functional and radiological outcomes.Introduction and Objective

Ankle fractures are common and affect young adults as well as the elderly. An unstable ankle fracture treatment typically involves surgical fixation, immobilisation, and modified weight-bearing for six weeks. Non-weight bearing (NWB) cast immobilisation periods were used to protect the soft tissue envelope and osteosynthesis. This can have implications on patient function and may reduce independence, mobility and return to work. Newer trends in earlier mobilisation compete with traditional NWB doctrine, and weak consensus exists as to the best postoperative strategy. The purpose of this trial is to investigate the safety and efficacy of immediate weight-bearing (IWB) and range of motion (ROM) exercise regimes following ORIF of unstable ankle fractures with a particular focus on functional outcomes and complication rates. A pragmatic randomised controlled multicentre trial, comparing IWB in a walking boot and ROM within 24 hours versus non-weight-bearing (NWB) and immobilisation in a cast for six weeks, following ORIF of all types of unstable adult ankle fractures (lateral malleolar, bimalleolar, trimalleolar with or without syndesmotic injury). The exclusion criteria are skeletal immaturity and tibial plafond fractures. The primary outcome measure is the functional Olerud-Molander Ankle Score (OMAS). Secondary outcomes include wound infection (deep and superficial), displacement of osteosynthesis, the full arc of ankle motion (plantar flexion and dorsal flection), RAND-36 Item Short Form Survey (SF-36) scoring, time to return to work and postoperative hospital length of stay.Introduction and Objective
