Delayed percutaneous intradiscal hydrogel herniation causing neurological injury after minor trauma: illustrative case.
J Neurosurg Case Lessons
December 2024
Section of Neurosurgery, Department of Clinical Neurosciences, University of Calgary, Calgary, Alberta, Canada.
Background: Percutaneous intradiscal hydrogel injection has been used to treat low-back pain (LBP) due to degenerative disc disease with or without mild radicular pain. Complications from these procedures are underreported. In this case lesson, the authors present a rare case of a patient with herniated intradiscal hydrogel following a minor trauma leading to neurological injury.

Adult-Acquired Flatfoot Deformity (AAFD) is a progressive orthopedic condition causing the collapse of the foot's medial longitudinal arch, often linked with injuries to the plantar arch's passive stabilizers, such as the spring ligament (SL) and plantar fascia. Conventional treatment typically involves replacing the SL with synthetic material grafts, which, while providing mechanical support, lack the biological compatibility of native ligaments. In response to this shortcoming, our study developed an electrospun, twisted polymeric graft made of polycaprolactone (PCL) and type B gelatin (GT), enhanced with graphene oxide (GO), a two-dimensional nanomaterial, to bolster biomechanical attributes.

Mayo Clinic, Jacksonville, FL, USA.
Context: Dystonia is a movement disorder that causes involuntary muscle contractions leading to abnormal movements and postures, such as twisting. Dystonia is the third most common movement disorder in the United States, with as many as 250,000 people affected. Because of its complexity, dystonia presents a significant challenge in terms of management and treatment.

Article Synopsis
- The Achilles tendon (AT) consists of three subtendons linked to the triceps surae muscles: gastrocnemius medialis, gastrocnemius lateralis, and soleus, each with distinct twisting patterns categorized as Type I, II, and III based on cadaver studies.
- In a study involving 30 healthy participants, ultrasound imaging was used to measure how different muscles affect AT displacement during stimulation, revealing that the soleus caused the greatest displacement.
- The research highlighted significant individual variations in AT structure and movement, moving from cadaver insights to practical understanding of its dynamic behavior in living subjects.
Biomechanical model of minimally invasive hallux valgus surgery.

College of Sciences, Northeastern University, Shenyang, China.
Article Synopsis
- - Hallux valgus is a foot deformity that causes the big toe to tilt outward and form a bump at the base, often treated through minimally invasive surgery for metatarsus adductus, which has quicker recovery and smaller scars.
- - The study utilizes a finite element method to create a biomechanical model for metatarsus adductus, analyzing different Kirschner wire fixation methods to understand their impacts on foot loading and stress distribution.
- - The research aims to improve the understanding of minimally invasive surgical techniques and their effectiveness, ultimately seeking to reduce complications and enhance patient satisfaction in surgeries for metatarsus adductus.
