The management of displaced forearm diaphyseal fractures in adults is predominantly operative. Anatomical reduction is necessary to infer optimal motion and strength. The authors have observed an intraoperative technique where passive pronosupination is examined to assess quality of reduction as a surrogate marker for active movement. We aimed to assess the value of this technique, but intentionally malreducing a simulated diaphyseal fracture of a radius in a cadaveric model, and measuring the effect on pronosupination. A single cadaveric arm was prepared and pronation/supination was examined according to American Academy of Orthopaedic Surgeons guidance. A Henry approach was then performed and a transverse osteotomy achieved in the radial diaphysis. A volar locking plate was used to hold the radius in progressive amounts of translation and rotation, with pronosupaintion measured with a goniometer. The radius could be grossly malreduced with no effect on pronation and supination until the extremes of deformity. The forearm showed more tolerance with rotational
1. The long-term results in a consecutive series of 323 healed subcapital fractures of the femur show that, with few exceptions, the capital fragment maintains its integrity when the fragments are aligned within the narrow limits of good reduction, but undergoes superior segmental collapse when reduction is poor. 2. The effect of
Introduction. Previous studies have demonstrated the need of accurate reduction of ankle syndesmosis. Measurement of syndesmosis is difficult on plain radiographs. Recently, a difference of 2mm in anterior and posterior measurements at incisura of the inferior tibio-fibular joint on CT has been described as a measure of
Tibial plateau fractures are common injuries. Displaced fractures are treated with open reduction and internal fixation (ORIF). Goals of treatment include restoration of extremity axial alignment, joint stability and congruity, allowing for early motion and prevention of osteoarthritis. Short term results of surgical fixation of tibial plateau fractures are good, however, longer term outcomes have demonstrated a higher risk of end-stage arthritis and total knee arthroplasty. Despite the vast literature around tibial plateau fractures, to our knowledge there are no series examining post-operative reductions using axial imaging. It is our goal to define the incidence of articular
Ankle fractures are the fourth most common fracture requiring surgical management. The deltoid ligament is considered the primary stabilizer of the ankle against a valgus force. The management of the deltoid ligament in ankle fractures is currently a controversial topic no consensus exists regarding repair in the setting of ankle fractures. The purpose of this systematic review is to examine the role and indications for deltoid ligament repair in ankle fractures. A systematic database search was conducted with Medline, Pubmed and Embase for relevant studies discussing patients with ankle fractures involving deltoid ligament rupture and repair. The papers were screened independently and in duplicate by two reviewers. Study quality was evaluated using the MINORs criteria. Data extraction included post-operative outcomes, pain, range of motion (ROM), function, medial clear space (MCS), syndesmotic
Introduction. Injury to the syndesmosis is not always clearly demonstrated on radiographs and different tests have been described to assess for injury. In the presence of a significant injury to the syndesmosis, surgical fixation is often indicated and various fixation methods have been described. If the result of surgery is any mal-reduction of the fibula, this may result in ongoing ankle pain. Assessing how well the fibula has been reduced intra-operatively is currently limited to image intensifier views. We have previously developed a simple assessment, which has been shown to give accurate intra-operative demonstration of an injury to the syndesmosis. Our objective was to ascertain if the same test could demonstrate any
Introduction. We performed a longitudinal outcome study involving the operative management of ankle fractures at two university teaching hospitals. This was a retrospective review of the quality of reduction and a prospective study into the functional outcome. Methods. All patients undergoing open reduction internal fixation of the ankle between November 2006 and November 2007 at one centre, and January to December 2009 at the other were included. Adequacy of reduction was assessed on the initial post-operative radiographs using Pettrone's criterion. The post-operative functional outcome was recorded using the Lower Extremity Functional Scale (LEFS), completed by postal or telephone follow-up at 64 months post injury (60–74 months). Results. There were 261 patients in the cohort, with a mean age of 47 years (17–91). Weber B fractures were sustained in 193 patients compared to 68 Weber C fractures. The medial malleolus was fractured in 43 cases, and a large posterior malleolar fragment (>20%) was found in 13 cases.
Background. Many approaches to management of medial malleolar fractures are described in the literature however, their morphology is under investigated. The aim of this study was to analyse the morphology of medial malleolar fractures to identify any association with medial malleolar fracture non-union or malunion. Methods. Patients who had undergone surgical fixation of their MMF were identified from 2012 to 2022, using electronic patient records in a single centre. Analysis of their preoperative, intraoperative, and postoperative radiographs was performed to determine their morphology and prevalence of non-union and malunion. Lauge-Hansen classification was used to characterise ankle fracture morphology and Herscovici classification to characterise MMF morphology. Results. A total of 650 patients were identified across a 10-year period which could be included in the study. The overall non-union rate for our cohort was 18.77% (122/650). The overall malunion rate was 6.92% (45/650). There was no significant difference in union rates across the Herscovici classification groups. Herscovici type A fractures were significantly more frequently malreduced at time of surgery as compared to other fracture types (p=.003). Medial wall blowout combined with Hercovici type B fractures showed a significant increase in malunion rate. There is a higher rate of bone union in patients who have been anatomically reduced. Conclusion. The morphology of medial malleolar fractures does have an impact of the radiological outcome following surgical management. Medial wall blowout fractures were most prevalent in adduction-type injuries; however, it should not be ruled out in rotational injuries with medial wall blowouts combined with and Herscovici type B fractures showing a significant increase in malunions. Herscovici type A fractures had significantly higher

Variations in pelvic anatomy are a major risk factor for misplaced percutaneous sacroiliac screws used to treat unstable posterior pelvic ring injuries. A better understanding of pelvic morphology improves preoperative planning and therefore minimises the risk of malpositioned screws, neurological or vascular injuries, failed fixation or
Lisfranc fracture dislocations of the midfoot are uncommon but serious injuries, associated with posttraumatic arthrosis, progressive deformity, and persistent pain. Management of the acute injury aims to restore anatomic tarsometatarsal alignment in order to minimise these complications. Reduction and stabilisation can be performed using image-guided percutaneous reduction and screw stabilisation (aiming to minimise the risk of wound infection) or through open plating techniques (in order to visualise anatomic reduction, and to avoid chondral damage from transarticular screws). This retrospective study compares percutaneous and open treatment in terms of radiographic reduction and incidence of early complications. Case records and postoperative radiographs of all patients undergoing reduction and stabilisation of unstable tarsometatarsal joint injuries between 2011 and 2014 in our institution were reviewed. Dorsoplantar, oblique and lateral radiographs were assessed for accuracy of reduction, with

The purpose of this project was to evaluate North American trauma surgeon preferences regarding patient positioning for antegrade fixation of mid shaft femoral shaft fractures. This project was a cross sectional survey taken of orthopaedic fellows and staff surgeons, belonging to three organizations across North America. An estimated sample size was calculated a priori, while various online techniques were utilized to reduce non responder and fatigue bias. The survey was distributed multiple times to optimize yield. Two hundred twelve (212) participants responded in full, 134 (56%) of whom practiced in Canada. The majority of surgeons worked in level one trauma centres (74%), while 72% treated more than one femoral shaft fracture per week. The most common patient position for mid shaft fixation amongst all surgeons was lateral positioning with manual traction (68%), however community surgeons were significantly more likely to use a fracture table. The most common difficulties faced with using a fracture table were inability to achieve fracture reduction and peroneal nerve palsies. The majority (64%) of surgeons quoted a complication rate with fracture tables of greater than 1 per 100 cases. Lateral position with use of manual traction is the preferred set up for antegrade fixation of femoral shaft fracture in this large North American cohort of trauma surgeons. However, a large subset of community and non academic surgeons still prefer use of the fracture table. Amongst all respondents, a high rate of fracture table complications, including
