Fracture related Infection - Challenges in definition and diagnosis

Markus Rupp, Nike Walter, Christoph Brochhausen, Volker Alt

Summary: In the field of orthopedics and trauma surgery, periprosthetic joint infections and fracture-related infections have become a growing concern. Despite the recent establishment of a definitive definition for FRI, diagnosing and treating these infections remains challenging and requires further research and optimization.

Articulated lengthening fixation apparatus (ALFA) for the management of gap non-union of distal femur: Initial experience on a new technique

Sunit Vardhan, Anil Regmi, Bishwa Bandhu Niraula, Bom Bahadur Kunwar, Vikas Olkha, Mohit Dhingra

Summary: This study evaluated the efficacy of using the ALFA fixator in the treatment of non-union of the distal femur. Eight patients were treated with the ALFA fixator, and their functional, radiological, and clinical outcomes were assessed. The ALFA fixator provided good distraction osteogenesis, minimal neurovascular complications, and preserved knee range of motion.

Does central sensitization correlate with two-year postoperative functional outcome scores following hip arthroscopy?

Andres R. Perez, William F. Baker, Neel K. Patel, Henson Destine, Rahul Muchintala, Austin Looney, Patrick Szukics, John P. Salvo

Summary: This study aimed to evaluate the impact of central sensitization on pain perception and functional recovery after hip arthroscopy. The study found that increased postoperative central sensitization index scores were directly correlated with decreased preoperative and postoperative functional scores and worse preoperative resilience.

Healed ORIF in a fibula fracture - Hardware removal or hardware retention for the fibula in a patient with minor symptoms?

Gareth Rooke, Paul Sharplin, Richard Buckley

Summary: A 31-year-old female suffered a right fibula fracture with deltoid ligament injury after falling while climbing on wet rocks. She had ORIF surgery and recovered well, but has developed vague pain and hardware sensation at the lateral ankle 6 months later. Her past medical history includes breast reduction surgery and vaginal delivery, and she has a social history of alcohol consumption and past recreational drug use.

Metacarpal and Phalangeal Nonunions

Stefan Czerniecki, Mark Mishu, Ryan Schmucker

Summary: Nonunion of the metacarpals and phalanges is rare but can severely impact hand function if not properly treated. Addressing factors such as inadequate reduction and stabilization of fracture fragments, poor blood supply, and infection is crucial for successful treatment. Stable fixation methods, well-vascularized soft tissue transfer, and appropriate management of infection and bone gaps are important considerations.

Lessons learned from biomechanical studies on cephalomedullary nails for the management of intertrochanteric fractures. A scoping review

Jorge Mayor, Vera Birgel, Jan-Dierk Clausen, Goekmen Aktas, Stephan Sehmisch, Ann-Kathrin Einfeldt, Vasilis Giannoudis, Ahmed H. K. Abdelaal, Emmanouil Liodakis

Summary: This study provides a comprehensive overview of biomechanical research on the treatment of intertrochanteric fractures using cephalomedullary devices. Through a systematic literature search and synthesis analysis, the study highlights the need for standardization in biomechanical studies, and suggests strategies to enhance construct stability. The findings emphasize the importance of further research and meta-analyses to establish standardized protocols and enhance reliability.

National analysis of over and under-triage rates in relation to trauma population risk factors and associated outcomes across various levels trauma centers

Jeffrey Hayashi, Maveric Abella, Denise Nunez, Noah Alter, Jason Kim, Abigail Rosander, Adel Elkbuli

Summary: This study evaluates the rates of over-triage and under-triage in trauma patients nationwide, as well as the associated risk factors and outcomes. The findings suggest that Pacific Islander and American Indian patients, Medicare beneficiaries, and patients treated at level II and III trauma centers are more likely to be over-triaged. Hispanic patients and privately insured patients, on the other hand, have a higher risk of under-triage.

Intrawound navigation for custom-made acetabular component in revision total hip arthroplasty: Does it improve implant positioning?

Rashid M. Tikhilov, Anton N. Kovalenko, Alisagib A. Dzhavadov, Stanislav S. Bilyk, Igor I. Shubnyakov

Summary: This study aims to develop a reliable and easily reproducible method for positioning custom-made acetabular components (CMAC) in hip revision surgery. The use of intraoperative navigation significantly improves the accuracy of implant positioning and reduces the risk of malpositioning. Navigation allows for better planning of implant and reamer sizes, providing optimal bone preparation and preservation in cases of massive bone defects.

Sex differences in dynamic joint stiffness during walking in older adults

Haruki Toda, Hiroaki Hobara, Mitsunori Tada

Summary: This study investigated sex differences in lower limb dynamic joint stiffness (DJS) during walking in older adults. The results showed that ankle DJS was lower in older women, which was caused by the reduced ankle plantarflexion moment. However, knee DJS did not elucidate the cause of knee osteoarthritis (OA) in older women.

Reliability and minimal detectable change of stiffness and other mechanical properties of the ankle joint in standing and walking

Luis H. Cubillos, Elliott J. Rouse, Thomas E. Augenstein, Varun Joshi, Edward S. Claflin, Chandramouli Krishnan

Summary: The study found that the reliability of stiffness, viscosity, and inertia of the ankle joint was good to excellent during standing. During walking, the reliability of stiffness and viscosity was also good to excellent, while that of inertia was fair to good. The minimal detectable change (MDC) ranged widely, but was higher for inertia during walking.

A new method regulates bone fracture tissue exosome lncRNA-mRNA to promote mesenchymal stem cell proliferation and migration

Dong Wang, Shuo Diao, Xiaobin Zhou, Junlin Zhou, Yang Liu

Summary: This study discussed the role of fracture site tissue exosomes lncRNAs-mRNAs networks on post-injury adaptation (PIA) promoting bone mesenchymal stem cells (BMSCs) proliferation and migration. The results confirmed that PIA accelerated BMSCs proliferation and migration, and identified tissue exosomes as the key factor in this process. By analyzing the tissue exosomes lncRNAs-mRNAs networks, several hub genes, such as Akt1, Actb, and Uba52, were identified, and Kif11 was found to be a key gene in BMSCs regulated by tissue-derived exosomes of PIA treated rats.

A comparison between ilioinguinal and modified Stoppa approach in anterior column acetabular fractures

M. Scrivano, A. Vadal, G. Fedeli, R. Di Niccolo, D. Topa, S. Porcino, F. Pallotta, A. De Carli

Summary: This study compares the outcomes and complications of Ilioinguinal versus modified Stoppa approach in Open Reduction and Internal Fixation (ORIF) of anterior column acetabulum fractures. The results show that the modified Stoppa approach has a shorter operative time, less intra-operative blood loss, and fewer complications. The ilioinguinal approach achieves better anatomic reduction. However, there were no significant differences in terms of vascular lesions, clinical and functional outcomes between the two groups.
