Introduction Several alternatives are now available when treating posttraumatic acute bone defects. Masquelet's technique represents a safe procedure to treat lower limb open fractures associated with significant bone defects and allows surgeons to try to reduce complications incidence. Material and Methods Retrospective study based on patients´ record files and images (2015-2017). Twelve patients suffering acute bone defect, treated using Masquelet technique, were evaluated. A total of ten patients were finally included after exclusion criteria were applied. Results Average time from injury to first stage surgery was 11 days. Free flaps were required in three cases (two latissimus dorsi and one anterolateral thigh flap). Time to second stage surgery was 115 days on average. As bone graft, reaming irrigation-aspiration system was associated to this technique. Consolidation was achieved in all patients but one after an average time of 8.4 months. There was only one case of limb shortening of 20 mm. There was no case of nonunion or infection, and patients could perform daily basic activities independently. VAS mean score was one point one year after final surgery. Conclusions Masquelet's technique achieves encouraging results when treating lower limb acute bone defects. Using this technique, surgeons could decrease infection incidence in open fractures with severe bone loss. On the other hand, it is a two-stage surgery process, which makes the process longer.

Factors that impede closed reduction in intertrochanteric fractures remain unknown. This study was designed with the aim of establishing radiological variables that can predict an open reduction when nailing those type of fractures.Observational prospective study carried out between March 2013 and March 2015. Patients of both gender who suffered an intertrochanteric fracture, and who were surgically treated by intramedullary nailing (PFN-A), were included. Patients were evaluated by means of a questionnaire designed in 12 de Octubre Trauma department. Radiological parameters assessed preoperatively, after fracture reduction in the traction table, and after fixation were: calcar, lateral wall and posterior buttress integrity or disruption; lesser trochanter location, varus or valgus deformities, and flexion or extension of the proximal fragment.Association between open reduction and the following types of fractures was statistically significant (p0.001): subtypes A2.3, A3.2 and A3.3 of AO classification and subtypes IV and V of Evans classification. There were four radiological parameters associated with the need for open reduction: disruption of lateral wall (p0.0000), posterior wall fracture (p0.001), calcar (p0.004) and malalignment in the axial view (p0.001).Open reduction seems to be necessary for complex fracture patterns such as A2.3, A3.2 and A3.3 types of AO/OTA classification, as well as types IV and V of Evans classification. There are four major radiological parameters that can predict the need of approaching the fracture site: posterior buttress, calcar disruption, lateral wall disruption and proximal fragment flexion. The development of high quality evidence regarding this topic is necessary due to the vast impact that open reduction can have on elderly patients.

The aim of the present study is to analyse complications after a floating elbow injury, attempting to establish which of them act as a poor prognosis factor regarding clinical and functional results. Twenty-three patients who suffered a floating elbow injury, treated at our institution from 2004 to 2013, were retrospectively reviewed. Patients were divided into four groups depending on the type of injury. An analysis of demographic data, associated injuries, treatment options and complications was carried out. Clinical evaluation was made by a conventional goniometer, testing flexo-extension and prono-supination ranges. For functional evaluation, the Mayo Elbow Performance Score was employed. Association between radioulnar synostosis, articular surface disruption, nerve injury and clinical and functional results was analysed. Patients with radioulnar synostosis had worse results in functional evaluation than patients without it (56.6 vs. 75); this difference was statistically significant (p = 0.05). Regarding intra-articular extension, we found statistical association with worse results in functional evaluation (p = 0.018); however, nerve palsy does not seem to influence functional results. Radioulnar synostosis and intra-articular extension of the injury are poor prognosis factor in floating elbow.

Introduction The distal triceps tendon rupture is an uncommon injury. The acute treatment is well-defined, but when a delayed diagnosis is made or when a tendon retraction is present the alternatives or reconstruction are limited and sometimes complex. Case Presentation In this case, we report on a 28-year-old man who presented with a chronic disruption of the distal triceps tendon with a gap of approximately 15 cm. The patient was diagnosed in another center with an inveterate breakage of the distal triceps tendon and was initially treated with an Achilles allograft that was complicated by a wound infection and required more than ten surgeries. Nearly 22 months after the initial trauma, and 12 months after the first surgery, we performed a reconstruction with an Achilles tendon allograft using the new technique of distal attachment. At the 12-month follow-up the patient presented a joint balance from -5º to 110º and presented with no pain. Conclusions The use of an Achilles tendon allograft provides excellent results in complex distal triceps tendon ruptures. We report the use of a new technique to anchor a distal Achilles allograft.
