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.

Classifying tibial plateau fractures is paramount in determining treatment regimens and systemizing decision making. The original AO classification described by Müller in 1996 and the Schatzker classification of 1970 are the most cited classifications for tibial plateau fractures, demonstrating substantial to almost perfect agreement. The main problem with these classifications schemes is that they lack the detail required to convey the variety of fracture patterns encountered. In 2018, the AO foundation published a new classification system for proximal tibia fractures, highlighting a more complete and detailed number of categories and subcategories. We sought to independently determine inter and intraobserver agreement of the AO classification system, compared to the previous systems described by Müller and Schatzker. ⋯ This study demonstrated an adequate inter and intra-observer agreement for the new AO tibial plateau fractures classification system for its base categories, but not at the subcategory or letter modifier levels.

Hypertrophic nonunion after intramedullary (IM) nailing and plating is Uncommon and the treatment remained controversial. The aim of this study was to show the result of a simple augmentative lag screws technique for vital non-unions after internal fixation PATIENTS AND METHODS: We retrospectively reviewed the patients with nonunion after internal fixation between January 2016 to August 2022. Patients with unacceptable shortening or deformity were excluded as well as nonunion septic cases. All the patients were followed up for at least 6 months. ⋯ Augmentative lag screws represent a simple technique for the management of aseptic hypertrophic nonunion after internal fixation with a significantly shorter operating time.

The most universal method for classifying pertrochanteric fractures is the AO/OTA classification. These fractures are classified into different categories according to the features found in the anteroposterior radiograph of the hip. Anteroposterior radiograph of the hip with internal rotation traction can improve the characterization of the fracture. Inter- and intra-observer reliability in any classification is essential to achieve a homogeneous agreement for decision making. Our objective is assessing the overall reliability and by level of experience of the new AO/OTA classification of pertrochanteric fractures. ⋯ Our study found that the internal rotation traction x-ray did not improve the reliability of the new AO/OTA classification for pertrochanteric fractures, as assessed by inter- and intra-observer agreement, in either the overall group or in groups divided by experience level.

Observational Study
Morbidity and mortality in hip surgery patients due to fracture during the COVID-19 pandemic.
The COVID-19 epidemic generated major changes in general surgical management protocols. The literature has reported high mortality rates for hip fracture surgery in patients with COVID-19. This study describes the morbidity and mortality in patients undergoing surgery due to hip fractures in 12 Colombian institutions between March and September 2020. ⋯ 520 patients received surgical treatment for hip fracture during the first six months of the COVID-19 pandemic in 12 medical centers in Colombia. 21.10% suffered a complication during the early stage (30 days) and 4.77% during the midterm stage (1-6 months). 4.8% were admitted in the ICU during the early stage. All-cause death was 27 patients, early death was 11 (40.74%) and midterm death was 16 (59.25%). 13 patients were positive for COVID-19, 3 died, one (1/5=20%) on the first 30 days and the other two (2/8=25%) from month 1 to 6.
