Using metal trans-syndesmosis screw was the most popular and mainstream approach to restore syndesmotic stability, although there is a lot of published information about malreduction of the syndesmotic screw and alternatives to syndesmotic screw fixation.[7],[8],[9],[10],[11],[12],[13] Intraoperative stress testing is recommended for diagnosing syndesmotic disruption or instability.
Fixation strategies to prevent screw cut-out and malreduction in proximal humeral fracture fixation.
Advantages of the piriformis start point include reduction of the incidence of varus malreduction and medial cortex injury with reaming [17].
A potentially serious, often underappreciated, complication of this procedure is rotational malreduction. In addition to presenting cosmetic dissatisfaction, torsional deformities may lead to a variety of disorders [3, 4].
However, there are still some undesired complications, such as glenoid notching, tuberosity malunion, prosthetic migration, prosthetic subluxation, rotator cuff lesion, heterotopic ossification, posttraumatic osteoarthritis, tuberosity displacement, or malreduction [21, 81].
The effect of fibular malreduction on contact pressures in an ankle fracture malunion model.
The surgical method most commonly considered to achieve this is intramedullary (IM) nailing.12,13 However, the medullary canal of the subtrochanteric area in the femur is broad and the proximal fragment is relatively short, which means that malreduction can occur easily.
Supracondylar humeral fractures are the most common fractures seen in children, It has a greater rate of malunion, nerve injury, and poor results than any type of extremity fracture.1, 2 In the past, it was thought that cubitus varus or cubitus valgus occurred because of growth arrest of the distal humeral epiphysis.3 Now it has been established that it is because of malreduction of the fracture.4
Conclusions: Medial support screws might help enhance mechanical stability and maintain fracture reduction when used to treat PHFs with medial metaphyseal comminution or malreduction.
Correction of fracture malreduction, improving fracture stability, and increasing biology to the fracture may all be necessary depending on the contributing factors to nonunion.
It should be noted that while the surgical team's use of intraoperative fluoroscopy ensured a safe path for the SI screws during the primary procedure, the malreduction was not identified, likely because the quality of the intraoperative fluoroscopy was deteriorated by the patient's obesity.
(2,4,11,26,27) ORIF allows for anatomic reduction, which prevents the development of radiographic arthritis associated with malreduction. In 2012, Leclere and colleagues reported a series of 24 patients undergoing ORIF with an average of 83 month follow-up.
