Antegrade fixation of posterior column fractures of the acetabulum is challenging due to the narrow corridor and risk of screw misplacement. Although both antegrade and retrograde lag screws have been previously described for posterior column fracture fixation, the literature lacks a standardized technique for correct and safe screw placement, especially in an antegrade fashion. This technical note aims to optimize intraoperative images during posterior screw insertion using the antegrade technique, according to predetermined landmarks to save surgical time, decrease radiation exposition, and prevent surgical complications.

Randomized Controlled Trial Multicenter Study
Outcomes of cement augmentation in fragility trochanteric hip fractures - A multicenter randomized controlled trial follow-up.
Cement augmentation is considered to improve the bone-implant construct stability in hip fragility fractures, additionally biomechanical studies show that cement augmentation improves the pull-out strength and increases resistance to failure. Thus far, the advantage of these technique used in a clinical scenario is yet to be determined METHODS: a randomized, multicenter, single-blinded clinical trial was conducted in patients aged 65 years or older who were admitted to two level I trauma centers with a fragility intertrochanteric hip fracture during September 2015 and December 2017. Patients were stratified into 2 groups: patients between 65 and 85 years and older than 85 years. A balanced block randomization was performed using blocks of 6 patients: 3 patients assigned to the control group (no augmentation) and 3 patients to the intervention group. Follow-up visits were done at 1, 3, 6 and 12 postoperative months documenting the tip-apex distance (TAD) as well as followed up after 5 to 7 years of surgical procedure documenting EQ5D, Parker Mobility Score and mortality rates at these different time points. ⋯ The use of augmentation can be considered a safe procedure for the fixation of fragility hip fractures.

Observational Study
Pediatric floating knee injuries: Clinical modifiers affecting sports and transfer outcomes.
This study assessed the functional outcome, and the clinical modifiers that influence them with the aim to assist the clinician plan a better management strategy in Paediatric Floating Knee (PFK) injuries. ⋯ Early recognition of clinical modifiers such as high ISS and bone loss > 4 cm warrants targeted limb reconstruction strategy and can help to prognosticate outcome.

Observational Study
Modified gastrocnemius splitting anatomic approach to the tibial plateau. Medium-term evaluation.
Posterior tibial plateau fractures, including avulsion fractures of the posterior cruciate ligament (PCL) insertion, represent a challenge for the orthopedic trauma surgeon. These injuries have gained a new perspective both diagnostically and therapeutically after the regular use of multiplanar computed tomography. In the herein study, we describe the outcome of patients sustaining a tibial plateau fracture with posterior articular involvement treated by open reduction and internal fixation (ORIF) using our modified gastrocnemius splitting anatomic approach. ⋯ The modified gastrocnemius splitting anatomic approach represents a good alternative for the management of tibial plateau fractures involving the posterior quadrants.

Femoral neck fractures (FNFs) affect the young adult population and are intimately related to high-energy trauma. Despite innovations in osteosynthesis materials, the rate of complications remains at 10%-59% in Pauwels type III (PIII) fractures. The authors thus propose a fixation model with a novel self-compression screw, comparing it to a sliding hip screw plate associated with a derotation screw in the fixation of a PIII fracture with posterior inferior comminution. ⋯ Fracture displacement and rotation values presented reductions of over 60% when comparing the XS and XI groups with the SHS+S group. Equivalent Von Mises stress values were similar between XS and XI and presented a reduction of approximately 5.25% when compared with the SHS+S group. Our FEM analyses demonstrated that the self-compression screw model has potential biomechanical advantages over the SHS+S model.
