    ABSTRACT: Syndesmotic rupture is present in 10 % of ankle fractures and must be recognized and treated to prevent late complications. The method of fixation is classically rigid fixation with one or two screws. Knowledge of the biomechanics of the syndesmosis has led to the development of new dynamic implants to restore physiologic motion during walking. One of these implants is the suture-button system. The purpose of this paper is to review the orthopaedic trauma literature, both biomechanical and clinical, to present the current state of knowledge on the suture-button fixation and to put emphasis on the advantages and disadvantages of this technique. Two investigators searched the databases of Pubmed/Medline, Cochrane Clinical Trial Register and Embase independently. The search interval was from January 1980 to March 2011. The search keys comprised terms to identify articles on biomechanical and clinical issues of flexible fixation of syndesmotic ruptures. Ninety-nine publications met the search criteria. After filtering using the exclusion criteria, 11 articles (five biomechanical and six clinical) were available for review. The biomechanical studies involved 90 cadaveric ankles. The suture-button demonstrated good resistance to axial and rotational loads (equivalent to screws) and resistance to failure. Physiologic motion of the syndesmosis was restored in all directions. The clinical studies (149 ankles) demonstrated good functional results using the AOFAS score, indicating faster rehabilitation with flexible fixation than with screws. There were few complications. Preliminary results from the current literature support the use of suture-button fixation for syndesmotic ruptures. This method seems secure and safe. As there is no strong evidence for its use, prospective randomized controlled trials to compare the suture-button to the screw fixation for ankle syndesmotic ruptures are required.

    ABSTRACT: Ankle fractures are one of the most frequently encountered musculoskeletal injuries, and 10% of patients have a concomitant distal tibiofibular syndesmotic disruption necessitating surgical repair. A national survey was conducted to gain more insight into the current approaches in the management of syndesmotic injuries in the Netherlands. A postal survey was sent to one or two staff members of the trauma and orthopaedic surgery departments in each of the 86 hospitals in the Netherlands. Questions concerned the pre-, per- and postoperative strategies and the different ideas on the type, number and placement of the syndesmotic screw. A total of 85.2% of the trauma surgeons and 61.9% of the orthopaedic surgeons responded (representing 87% of all hospitals). Syndesmotic injury was judged mainly using the 'Hook test'. Syndesmotic injuries in a Weber-B ankle fracture were treated with one screw in 81.2% of cases and in Maisonneuve injuries mainly with two screws. The 3.5-mm screw was used most frequently over three cortices at 2.1-4.0cm above the tibial plafond. Removal of the syndesmotic screw was routinely done by 87.0% of surgeons, mostly between 6 and 8 weeks. Of all respondents, 62.3% showed interest in participating in a randomised controlled trial comparing standard removal with removal on indication. Compared with previous surveys our survey is more complete, has the highest response rate and has almost national coverage. Most individual items reviewed compare well with current literature, except for the routine removal of the syndesmotic screw, which might not be encouraged from a literature point of view. For this reason, the results of the current survey will be used in the development of a multicentre randomised controlled trial comparing the functional outcome in routine removal of the syndesmotic screw compared with removal on indication.

    ABSTRACT: Paediatric blunt hepatic trauma treatment is changing from operative treatment (OT) to non-operative treatment (NOT). In 2000 the American Pediatric Surgical Association has published guidelines for NOT of these injuries. Little is known about the treatment of paediatric liver trauma in the Netherlands. Data of all patients aged 18 years and younger admitted to our hospital for blunt hepatic trauma in the past 18 years were retrospectively analysed using a prospective trauma registry. The mechanism of injury, treatment, ICU admission time, total admission time, morbidity and mortality were assessed. Subsequently the group was divided into patients treated before and after 2000. Eighty patients were identified: 52M, 28F with a mean age of 12 years (range 2-18). Thirty patients sustained isolated liver injury. Concomitant injuries were fractures of long bones (28), abdominal (25), chest (24) and head injuries (18). Mean ISS score was 18 (range 4-57). Mortality was 8%. Mechanisms of injury consisted of bicycle (25%), car (20%), and motorcycle accidents (15%), pedestrian hit by vehicle (15%), fall from height (14%) and accidents associated with animals (11%). Haemodynamically stable patients underwent NOT (55). 25 patients (31%) underwent a laparotomy, which in 20 cases (80%) was related to hepatic injury. Although the groups treated before and after 2000 did not differ haemodynamically on admission to hospital, a shift to NOT is evident: 24/37 (63%) patients underwent NOT before 2000 versus 38/45 (84%) after 2000 (p=0.04). Complications following NOT were rare. Late onset bleeding did not occur. Two patients developed an infected biloma, requiring a laparotomy. Mean ICU stay before 2000 was 4.2 days (range 0-25 days) and 2.6 days (range 0-17 days) after 2000. Total hospital time did not decrease: 14 days (range 1-39 days) before 2000 and 14 days (range 1-60 days) after 2000. The overall mortality was 8%. All deaths occurred in the operative group and were spread evenly over both periods. In blunt paediatric liver trauma, the incidence and trauma mechanism seem age-related. A shift to NOT is found in the treatment of paediatric blunt hepatic trauma. NOT is the preferred treatment for the haemodynamically stable patient. Complications are rare and the success rate is 96%. The mean ICU stay has decreased but the total admission time could possibly be shortened.
