A modified cable wiring technique with C-shaped passer through a mini-open approach to assist reduction in femoral fractures.

Femur fractures reduction can be technically challenging due to the deforming forces exerted by the muscles causing displacement of the fracture fragments. Cerclage wiring is one of the reduction techniques frequently performed, allowing anatomical reduction of the fragments and a more stable fixation when an accurate closed reduction is not possible. We describe a modified cerclage wiring through a minimally invasive technique, using a conventional cannulated C-shaped passer.

Comparative study between fixed-angle and polyaxial screws in distal radius fixation with two volar locking plates.

INTRODUCTION: When treating a distal radius fracture with a volar locking plate (VLP), numerous plate-screw designs are available. To date, there is not a screw fastening system with a clear superiority among the others. HYPOTESIS: Fixed-angle screws are superior to polyaxial screws in distal radius VLP fixation with respect to screw protrusion and reduction preservation. MATERIAL AND METHODS: A prospective cohort study based on eighty patients was performed. The first forty patients were treated by polyaxial VLP (PA group) were the next forty by a fixed-angle VLP (FA group). Fixation was performed by the flexor carpi radialis approach. Screws were placed 2mm shorter than actual measurement and intraoperative AP, lateral and tilt wrist views were done routinely. A computed tomography (CT) was conducted searching for screw protrusion. Loss of reduction was calculated from the difference between post-operative x-rays values and those at the 6-month follow-up. The total follow-up was 12 months with no losses. RESULTS: Postoperative CT detected dorsal screw protrusion in 17 patients in PA group and 16 patients in FA group that intraoperative radiographs were assumed as correct (p=0.48). The mean invasion of dorsal cortex was of 2.2mm (1-7mm) for PA group and 2.6mm (1-5mm) for FA group (p=0.70). As from those protruding screws, the mean size was registered founding that fixed-angle screws had protrusions with shorter screws 20 vs. 22mm (p<0.05). Intraarticular screw protrusion was registered in 3 and 2 patients respectively (p>1.0). Experienced loss of reduction in volar tilt (p=0.42), radial inclination (p=0.75) and ulnar variance (p=0.83) were equivalent in both groups while a better preservation of the radial height in the PA group was observed (p<0.05). DISCUSSIONS: In terms of screw protrusion rate, both fastening systems where similar. However, fixed-angle group invaded the dorsal cortex with shorter screws. Polyaxial screws were associated with a better preservation of the radial height. Finally, this study reinforces the idea that dorsal and articular screw protrusion is more frequent than we expected. LEVEL OF EVIDENCE: II; therapeutic, prospective cohort study.

Olecranon mayo IIA fractures treated with transosseous high strength suture: A series of 29 cases.

BACKGROUND: The aim of this study is to assess the causes and rates of re-operation in olecranon fractures in adults treated with transosseous suture. METHODS: We prospectively recruited 29 patients who were treated with this technique between 2010 and 2018. The type of suture used, tourniquet time and surgical time were analyzed for each one. X-rays were taken after 2 weeks, 6 weeks and 6 months, recording complications, causes, rates of re-operation and the final clinical condition. RESULTS: Median time for ischemia and surgery were 51 (95% CI:48;62) and 45 (95% CI:42;55) minutes respectively. The radiologic studies showed diastasis of the posterior cortex in the X-rays taken after 2 weeks and after 6 weeks in 7 (24,1%) cases. Of these cases, two (6,8%) were no longer followed-up after 6 months. There was only one case of aseptic non-union. Among these cases, two patients (6.8%) required surgical debridement due to acute soft tissue infection. No complication had any clinical impact, maintaining all patients full range of motion and no pain. Osteosynthesis removal was not necessary in any case. CONCLUSION: Transosseous suture with high strength thread is a valid alternative for treating Mayo IIA olecranon fractures in adult patients, decreasing re-operation rates for implant removal. There may be, in a moderate percentage of cases, radiologic diastasis of the posterior cortex at the fracture site, without causing pain nor limiting mobility LEVEL OF EVIDENCE: III.

Prevention of postoperative bleeding in hip fractures treated with prosthetic replacement: efficacy and safety of fibrin sealant and tranexamic acid. A randomised controlled clinical trial (TRANEXFER study).

INTRODUCTION: We assessed the efficacy of fibrin sealant (FS) and tranexamic acid (TXA) administered topically in patients with a hip fracture treated with prosthetic replacement. MATERIALS AND METHODS: Parallel, multicentre, open label, randomised, clinical trial. We compared three interventions to reduce blood loss: (1) 10 ml of FS, (2) 1 g of topical TXA, both administered at the end of the surgery, and (3) usual haemostasis (control group). The main outcome was blood loss collected in drains. Other secondary variables were total blood loss, hidden blood loss, transfusion rate, average hospital stay, complications, adverse events, and mortality. RESULTS: A total of 158 patients were included, 56 in the FS group, 52 in the TXA group, and 50 in the control group. The total amount of blood collected in drains was lower in the TXA group (148.6 ml, SD 122.7 in TXA; 168.2 ml, SD 137.4 in FS; and 201.5 ml, SD 166.5 in control group) without achieving statistical significance (p = 0.178). The transfusion rate was lower in the TXA group (32.7%), compared with FS group (42.9%) and control group (44.0%), without statistical significance (p = 0.341). There were no complications or adverse effects related to the evaluated interventions. CONCLUSIONS: The use of TXA and FS administered topically prior to surgical closure in patients with a sub-capital femoral fracture undergoing arthroplasty did not significantly reduce either postoperative blood loss or transfusion rate, compared with a group that only received usual haemostasis.

LISS plate for treatment of distal femur fracture. Clinical and functional outcomes.

The aim of the present study is to evaluate the use of the Less Invasive Stabilization System (LISS) plate for distal femoral fractures, examining variables such as type of fracture and length of plate. A retrospective study of 30 patients with a distal femoral fracture, treated with a distal femur LISS plate (Synthes) was performed. Average age was 71 years old (20-101). According to the AO classification, 16 fractures were type A, 5 type B, and 9 type C. The consolidation index and clinical outcomes measured with Knee Society Score (KSS) questionnaire were evaluated. Fracture consolidation took an average time of 16 weeks (14-20). Mean KSS was 77,3 (50-97) at the 2-year follow-up visit, observing better outcomes on type C fractures (84,25). According to the KSS score, only two cases were described with bad functional outcomes (6%). Distal femur fractures treated with the LISS plate achieved 94% of good and acceptable outcomes. Unlike the previously published, the best results were obtained with AO type C fractures, probably associated to the lower age (mean 53 years old) and better functional recovery capacity of this group.

Treatment strategy for tibial plateau fractures: an update.

Tibial plateau fractures are complex injuries produced by high- or low-energy trauma. They principally affect young adults or the 'third age' population.These fractures usually have associated soft-tissue lesions that will affect their treatment. Sequential (staged) treatment (external fixation followed by definitive osteosynthesis) is recommended in more complex fracture patterns. But one should remember that any type of tibial plateau fracture can present with soft-tissue complications.Typically the Schatzker or AO/OTA classification is used, but the concept of the proximal tibia as a three-column structure and the detailed study of the posteromedial and posterolateral fragment morphology has changed its treatment strategy.Limb alignment and articular surface restoration, allowing early knee motion, are the main goals of surgical treatment. Partially articular factures can be treated by minimally-invasive methods and arthroscopy is useful to assist and control the fracture reduction and to treat intra-articular soft-tissue injuries.Open reduction and internal fixation (ORIF) is the gold standard treatment for these fractures. Complex articular fractures can be treated by ring external fixators and minimally-invasive osteosynthesis (EFMO) or by ORIF. EFMO can be related to suboptimal articular reduction; however, outcome analysis shows results that are equal to, or even superior to, ORIF. The ORIF strategy should also include the optimal reduction of the articular surface.Anterolateral and anteromedial surgical approaches do not permit adequate reduction and fixation of posterolateral and posteromedial fragments. To achieve this, it is necessary to reduce and fix them through specific posterolateral or posteromedial approaches that allow optimal reduction and plate/screw placement.Some authors have also suggested that primary total knee arthroplasty could be an option in specific patients and with specific fracture patterns.
