Traumatic brain injury and alcohol intoxication: effects on injury patterns and short-term outcome.

PURPOSE: A significant number of patients with traumatic brain injuries (TBI) are diagnosed with elevated blood alcohol concentration (BAC). Recent literature suggests a neuroprotective effect of alcohol on TBI, possibly associated with less morbidity and mortality. Our goal is to analyze the association of different levels of BAC with TBI characteristics and outcome. METHODS: Adult patients with moderate to severe TBI (AIS ≥ 2) and measured BAC admitted to the Trauma Centre West (TCW), during the period 2010-2015, were retrospectively analyzed. Data included injury severity (AIS), length of hospitalization, admittance to the Intensive Care Unit (ICU) and in-hospital mortality. The association of BAC with ICU admittance and in-hospital mortality was analyzed using multivariable logistic regression analysis with correction for potentially confounding variables. RESULTS: BACs were available in 2,686 patients of whom 42% had high, 26% moderate, 6% low and 26% had normal levels. Patients with high BAC's were predominantly male, were younger, had lower ISS scores, lower AIS-head scores and less concomitant injuries compared to patients in the other BAC subgroups. High BACs were associated with a lower risk for in-hospital mortality (AOR 0.36, 95% CI 0.14-0.97). Also, patients with moderate and high BACs were less often admitted to the ICU (respectively, AOR 0.36, 95% CI 0.25-0.52 and AOR 0.40, 95% CI 0.29-0.57). CONCLUSION: The current study suggests that in patients with moderate to severe TBI, increasing BACs are associated with less severe TBI, less ICU admissions and a higher survival. Further research into the pathophysiological mechanism is necessary to help explain these findings.

Patient-reported outcomes after a distal radius fracture in adults: a 3-4 years follow-up.

Background and purpose - There are few reports on the outcome of distal radius fractures after 1 year. Therefore we investigated the long-term patient-reported functional outcome and health-related quality of life after a distal radius fracture in adults. Patients and methods - We reviewed 823 patients, treated either nonoperatively or operatively in 2012. After a mean follow-up of 3.8 years 285 patients (35%) completed the Patient-Rated Wrist Evaluation (PRWE) and EuroQol-5D. Results - The mean PRWE score was 11. The mean EQ-5D index value was 0.88 and the mean EQ VAS for self-rated health status was 80. Nonoperatively treated type A and type B fractures had lower PRWE scores compared with operatively treated patients, whereas the EQ-5D was similar between groups. The EQ VAS for patients aged 65 and older was statistically significantly lower than that of younger patients. Interpretation - Patients had a good overall long-term functional outcome after a distal radius fracture. Patients with fractures that were possible to treat nonoperatively had less pain and better wrist function after long-term follow-up than patients who needed surgical fixation.

Medium-sized posterior fragments in AO Weber-B fractures, does open reduction and fixation improve outcome? the POSTFIX-trial protocol, a multicenter randomized clinical trial.

BACKGROUND: Guidelines for treatment of the posterior fracture fragment in trimalleolar fractures are scarce and show varying advices. Did the increasing size of the posterior fragment seem to relate to worse outcome in the past, nowadays this has changed to the amount of dislocation of the posterior fragment post-operatively. Despite many retrospective cohort studies and some prospective cohort studies, no consistent guideline could be derived from the current literature. METHODS: The POSTFIX-study is designed as a multicenter randomized clinical trial to analyse the effects of anatomical reduction and fixation of the posterior fragment in AO 44-B3 fractures with medium-sized posterior fragment. A total of 84 patients will be included and online allocated to either anatomical reduction and fixation of the posterior fragment via the posterolateral approach (n = 42) or no fixation of the posterior fragment (n = 42). The concomitant fractured medial and lateral malleoli are treated according to the AO-principles. Functionality of the ankle as measured by the AAOS-questionnaire (American Association of Orthopaedic Surgeons) 1 year post-operatively was set as primary outcome. Main secondary outcome measures are the AAOS-questionnaire 5 years postoperatively and osteoarthritis as measured on plain radiographs 1 year and 5 years post-operatively. The Olerud and Molander score, the AOFAS-score, the VAS-pain, the Euroqol-5D and Range of Motion by physical examination will also be evaluated during the follow-up period. DISCUSSION: The POSTFIX-trial is the first high quality multicenter randomized clinical trial worldwide to analyse the effects of anatomical fixation of the posterior fragment in trimalleolar fractures. New guidelines on anatomical reduction and fixation of the posterior fragment can in future be based on the results of this trial. TRIAL REGISTRATION: This trial is registered on ClinicalTrials.gov with reference number: NCT02596529 . Registered 3 November 2015, retrospectively registered.

Talar Fractures in Children: A Possible Injury After Go-Karting Accidents.

Go-karting is an increasingly popular high-energy sport enjoyed by both children and adults. Because of the speeds involved, accidents involving go-karts can lead to serious injury. We describe 6 talar fractures in 4 patients that resulted from go-karting accidents. Talar fractures can cause severe damage to the tibiotalar joint, talocalcaneal or subtalar joint, and the talonavicular joint. This damage can, in turn, lead to complications such as avascular necrosis, arthritis, nonunion, delayed union, and neuropraxia, which have the potential to cause long-term disability in a child.

Evidence-based treatment of open ankle fractures.

Fractures of the ankle are fairly common injuries. Open ankle fractures are much less common and associated with severe injuries to surrounding tissues. We have performed a systematic review of the literature concerning the clinical results and complication rates in the treatment of open ankle fractures. We conducted a search limited to the following databases: Pubmed/Medline, Cochrane Database of Systematic Reviews, Cochrane Clinical Trial Register and Embase. These were searched from 1968 to April 2010 to identify studies relating to the treatment of open ankle fractures. Fifteen articles concerning 498 patients with treatment of an open ankle fracture were identified. The number of included patients varied from 11 to 64. There were 2 prospective and 13 retrospective studies. All articles were case series and classified as Level IV evidence. In 373 cases, open ankle fractures were treated by immediate internal fixation. In 125 cases, a conservative treatment or delayed/other fixation treatment was followed. Of those patients treated by immediate internal fixation, 81% had satisfactory result. Poor results (15%) were most commonly due to non-anatomic reductions, articular surface damage or deep infection. When conservative treatment was followed, 76% had satisfactory results. The most reported complications after immediate internal fixation were deep infection (8%) and skin necrosis (14%). There is a lack of high quality literature concerning the (operative) treatment of patients with open ankle fractures. Remarkable is that most authors reported satisfactory results after performance of their treatment protocol. Based on the available literature, we formulated guidelines regarding: timing of operative treatment, wound irrigation, the role of internal fixation, wound coverage and closure, the use of antibiotics and additional therapies.

[Traumatic atlas fracture in a child following fall on head]. / Traumatisch atlasletsel na een val op het hoofd bij een kind.

An 8-year-old girl presented at the Accident & Emergency Department with torticollis and neck pain after falling on her head from a climbing frame. A computed tomography scan revealed a Gehweiler type 1 avulsion fracture combined with widening of an anatomically variant single anterior synchondrosis. The child was successfully treated with halter traction, painkillers and bed rest. Physicians should look out for upper cervical spine injury in children who sustained a cranial axial load injury. Differential diagnosis between pain-reactive muscular torticollis and atlantoaxial rotatory subluxation is essential. Children presenting with posttraumatic torticollis require a conventional or dynamic computed tomography scan.

Long-term reendothelialization of excimer laser-assisted nonocclusive anastomoses compared with conventionally sutured anastomoses in pigs.

OBJECT: In contrast to conventional anastomosis methods, the excimer laser-assisted nonocclusive anastomosis (ELANA) technique involves a platinum ring and intima-adventitia apposition with a rim of medial and adventitial layers exposed to the bloodstream. The authors assessed the reendothelialization of porcine carotid arteries through ELANA compared with conventional anastomosis by using scanning electron microscopy. METHODS: In 28 pigs a bypass with one ELANA and one conventional anastomosis was made on the left common carotid artery. All patent anastomoses were evaluated intraoperatively with the aid of an ultrasonographic flowmeter and postoperatively by using scanning electron microscopy at 2 weeks, 2 months, 3 months, and 6 months thereafter. Twenty-four of 28 bypasses (48 of 56 end-to-side anastomoses) were fully patent at the time of evaluation. On scanning electron microscopic evaluation of the bypasses, all 48 patent anastomoses showed complete reendothelialization, including all 24 ELANAs in which the endothelium covered the rim and the laser-ablated edge completely. No endothelial difference was observed between conventional anastomoses and ELANAs, aside from the obvious anatomical differences like the platinum ring, which had been completely covered with endothelium. At 6 months postsurgery, remodeling of the ELANA was observed, leaving the ring covered with a layer of endothelium as the most narrow part of the anastomosis. CONCLUSIONS: In long-term experiments, ELANA allows reendothelialization comparable to that achieved with conventional anastomosis. Considering its nonocclusive and high-flow characteristics, the ELANA technique is preferable in cerebral revascularization procedures.
