Far Posterior Approach for Rib Fracture Fixation: Surgical Technique and Tips.
JBJS Essent Surg Tech
December 2024
Department of Orthopedics, OhioHealth Health System, Columbus, Ohio.
Article Synopsis
- The video article discusses the far posterior or paraspinal approach for treating posterior rib fractures, which enhances intraoperative visibility and minimizes muscle damage.
- This method helps preserve periscapular strength, achieving up to 95% recovery six months after surgery through muscle-sparing techniques.
- The surgical process involves precise skin incision and careful dissection of muscles like the trapezius, rhomboids, and latissimus dorsi to allow for effective access and treatment of the fractures without significant tissue loss.
Complete traumatic laceration of the superior mesenteric vein after a blunt abdominal injury in a pediatric patient.
Acta Chir Belg
December 2024
Department of Surgery, Charles University, University Hospital Hradec Králové, Hradec Králové, Czech Republic.
Article Synopsis
- Isolated superior mesenteric vein (SMV) injuries from blunt abdominal trauma, though rare, can be life-threatening, especially in children, and lack established treatment guidelines.
- A 10-year-old girl suffered a complete SMV laceration after a severe car accident and underwent successful urgent surgery that included using a graft from her internal jugular vein to repair the vein.
- The report emphasizes that proper vascular repair can prevent intestinal damage and highlights the internal jugular vein as an effective graft option in serious SMV injuries.
Sensory nerve EP4 facilitates heterotopic ossification by regulating angiogenesis-coupled bone formation.

Department of Orthopaedics and Traumatology, Nanfang Hospital, Southern Medical University, Guangzhou, Guangdong, 510515, China.
Article Synopsis
- Heterotopic ossification (HO) is the formation of bone in soft tissues, which can lead to significant issues, and the study investigates the role of sensory nerve EP4 signaling in this process, particularly in the Achilles tendon.
- Researchers created specific knockout mice and used various techniques, including transcriptome sequencing and a neurectomy model, to explore the effects of sensory nerve EP4 on HO development and the mechanisms involved.
- The study found that sensory nerve EP4 promotes HO by enhancing angiogenesis and identified the Efnb2/Dll4 signaling pathway as a key player, with EP4 inhibitors showing promise in reducing HO, indicating a potential target for treatment.
Combined In Vivo Electroporation and Short-Term Reinnervation of the Cranial Levator Auris Longus Skeletal Muscle.

The neuromuscular junction (NMJ) is the peripheral synapse controlling the contraction of skeletal muscle fibers to allow the coordinated movement of many organisms. At the NMJ, a presynaptic motor axon terminal contacts a muscle postsynaptic domain and is covered by terminal Schwann cells. The integrity and function of the NMJ is compromised under several conditions, including aging, neuromuscular diseases, and traumatic injuries.
