Conjoint bicondylar hoffas fracture with ipsilateral femur and tibia shaft fracture in pediatric patient

Abstract Introduction Population-based knowledge on the occurrence of specific injuries is essential for the allocation of health care services, optimization of preventive measures, and research purposes. Therefore, the aim of this study was to examine long-term nation-based trends in the incidence rate, trauma mechanism, hospital length of stay (HLOS), treatment, and outcome of hospital-admitted patients with an isolated tibia shaft fracture between 1991 and 2012 in The Netherlands. Methods All hospital-admitted patients in The Netherlands between 1991 and 2012 with an isolated tibia shaft fracture were included. Age and gender-standardized incidence rates were calculated for each year. Data were extracted from the National Medical Registration. Results The incidence rate for men decreased to 13.8/100,000 person years (py). For women the incidence rate remained stable with 7.2/100,000 py. Incidence showed a peak for adolescent men (15–19 years), and increased in both genders from 65 years onwards. Since 1993 the mean HLOS for isolated tibia fractures reduced from 10.8 to 5.4 days. Mean HLOS increased with age. Mean years lived with disability (YLD) was 4.5 years, declined linearly with age, and showed no gender effect. Conclusions In 22 years, the incidence rate of hospital admitted patients with an isolated tibia shaft fracture in The Netherlands dropped with 12%, which was mainly attributable to a 15% decline among men. Incidence rate, trauma mechanism, and HLOS were age and gender related. HLOS also reduced over time. Operation rate and YLD were only age related.

Introduction: Interlocking tibia nail fixation for tibia shaft fracture treatment is one of the most commonest procedures performed in orthopedic trauma practices. We report one such case of a rare complication of anterior tibial artery (ATA) pseudo-aneurysm caused by the proximal coronal locking bolt performed by an unusual entry from lateral to medial side during shaft of tibia fracture fixation. Case Report: A 86- years old female sustained a road traffic accident and was diagnosed with a closed tibia shaft fracture of the right leg for which she underwent intramedullary interlocking nail IMIL nailing elsewhere. She presented to us three 3 weeks after primary surgery with persistent pain and swelling in the right leg proximally. We investigated and diagnosed her as having a pseudoaneurysm of the Anterior Tibial Artery on color Doppler and magnetic resonance imaging (MRI) angiography. The pseudoaneurysm of ATA was clipped without any complications. To avoid the rupture of the pseudoaneurysm during manipulation of nail and bolts, their positions were not changed as they were supporting the fracture well and the fracture was also not united at that time. Conclusion: Though Although interlocking nailing of tibia shaft fracture is a commonly performed procedure, it can lead to disastrous vascular complications if the procedure is not performed with utmost care. ATA injury by proximal locking bolts of the tibia nail mandates the need for reconsideration of the nail design with better screw hole positions. We recommend preferring standard AO manual instructions for proximal tibia locking bolt direction. Keywords: Pseudo-aneurysm, tibia nail, locking bolt, anterior tibial artery.

Biomechanical perspective of external fixator is one of the biggest elements that should be considered in treating fracture bone. This is due to the mechanical behavior of the structure could be analyzed and optimized in order to avoid failure, increase bone fracture healing rate and prevents preterm screw loosening. There are three significant factors that affect the stability of external fixator and those are the placement of pin at the bone, configuration and components of external fixator. All these factors contribute to a question, what is the optimum pin diameter which exerts good stress distribution? To date, the research on the above-mentioned factors are limited in the literature. Therefore, this study was conducted to evaluate the unilateral external fixator with different pin sizes in treating tibia shaft fracture via the finite element method. First and foremost, the development of the tibia shaft fracture was conducted using Mimics software. The computed tomography (CT) data image was utilized to develop three-dimensional tibia bone followed by crafting fracture on the bone. Meanwhile, the unilateral external fixator was developed using SolidWorks software. In this study, five pin diameters (4.5, 5.0, 5.5, 6.0 and 6.5 mm) were developed and analyzed. Both tibia bone and external fixator were meshed in 3-matic software. Simulation of this configuration took place in a finite element software, Marc.Mentat. From the findings, it is shown that the larger diameter of pin demonstrated the lowest stress distribution. The size of the 5.5mm pin shows optimum diameter in terms of stress distribution with the value of 21.50 MPa in bone and 143.33 MPa in fixator. Meanwhile the displacement value of 1.42mm in bone and 1.20mm in fixator. In conclusion, it is suggested that the pin diameter of 5.5 mm is the most favorable option in treating tibia shaft fracture in terms of mechanical perspective.
