The effects of intercalary fragments at the posterior malleolus on ankle joint pressure distribution - a biomechanical cadaveric study.

Introduction: With the increased use of computed tomography scans in cases with trimalleolar ankle fractures, bone fragments between the posterior malleolus and the rest of the articular surface tibial plafond surface - described as intercalary fragments (ICFs) - can be recognized. The aim of this study was to determine the ICF size threshold for a significant change in the pressure distribution at the ankle joint, having a considerable impact on the remaining cartilage of the joint.

Design And Methods: Eight human cadaveric lower legs were used, and a posterior malleolus Bartoniček/Rammelt II fracture was created with sequential 2 mm, 4 mm, 6 mm, and 8 mm ICFs.

Optimizing management strategies for malunion and nonunion of Hoffa fractures: a detailed case series with a proposed treatment algorithm.

Purpose: This study aims to refine management strategies for malunion and nonunion of Hoffa fractures, as these rare complications present significant clinical challenges.

Methods: We conducted a case series involving seven patients with Hoffa fracture complications, including four cases of malunion and three cases of nonunion. Each patient underwent individualized surgical treatment, depending on the nature of their complication.

Paraperitoneal inguinal hernia of ureter.

Introduction: The ureter is present in surgical field during inguinal hernia repair in 0.5-4% of cases. It typically occurs in obese patients, in men and patients after kidney transplants.

The internal rotation traction radiograph does not improve the reliability in the AO classification system for pertrochanteric fractures. An inter- and intra-observer reliability assessment.

Introduction: 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.

Bisphosphonates and atypical femoral fractures: Is the location of the fracture associated with the time of consolidation?

Introduction: Bisphosphonates are commonly prescribed to mitigate the effects of osteoporosis, a condition associated with an increased risk of fracture. However, despite their success, there has been growing concern regarding the long-term use of bisphosphonates because of the increased risk of atypical subtrochanteric fractures of the femur (AFFs). The objective of this study was to describe a cohort of patients with AFFs and evaluate the risk of evolving to non-union, the time of consolidation associated with the location of the fracture, the time of use of the drug, and the implant involved in its treatment.
