Ki Seong Eom

J Korean Neurosurg Soc 2020 May 8. Epub 2020 May 8.

Department of Neurosurgery, Institute of Wonkwang Medical Science, Wonkwang University Hospital, Iksan, Korea.

Objective: Traditionally, staged surgery has been preferred in the treatment of compound comminuted depressed fracture (FCCD) after traumatic brain injury (TBI) and involves the removal of primarily damaged bone and subsequent cranioplasty. The main reason for delayed cranioplasty was to reduce the risk of infection-related complications. Here, the author performed immediate reconstruction using a titanium mesh in consecutive patients with FCCD after TBI, reported the surgical results, and reviewed previous studies. Read More

Cranial Reconstruction with Titanium Mesh for Open Depressed Skull Fracture in Children: Reports of Two Cases with Long-term Observation.

Kurume Med J 2020 Jul 1;66(1):77-80. Epub 2020 May 1.

Department of Neurosurgery, Graduate School of Life Sciences, Kumamoto University.

In the treatment of open depressed skull fracture in pediatric cases, it is preferable to use the patient's own bone material rather than artificial material. However, there are occasions when self-material reconstruction may be impossible. In such cases the safe option is to leave the defect until future replacement of the skull becomes possible, however this often causes such children to experience severe limitations to school life.

A Novel Approach to Scaling Age-, Sex-, and Body Size-Dependent Thoracic Responses using Structural Properties of Human Ribs.

Stapp Car Crash J 2019 Nov;63:307-329

Injury Biomechanics Research Center, The Ohio State University.

Thoracic injuries are frequently observed in motor vehicle crashes, and rib fractures are the most common of those injuries. Thoracic response targets have previously been developed from data obtained from post-mortem human subject (PMHS) tests in frontal loading conditions, most commonly of mid-size males. Traditional scaling methods are employed to identify differences in thoracic response for various demographic groups, but it is often unknown if these applications are appropriate, especially considering the limited number of tested PMHS from which those scaling factors originate.

Recent literature suggests that sublaminar bands (SB) can provide good coronal plane correction, comparable to pedicle screw constructs, as well as good correction in the sagittal plane, even in patients with preoperative hypokyphosis; comparable results have been reported in patients with adolescent idiopathic scoliosis (AIS) and in patients with neuromuscular scoliosis (NMS). Two types of SB constructs can be performed: the band-only construct, indicated for non-ambulatory patients with NMS, and the hybrid construct indicted for ambulatory patients with NMS and for patients with AIS. SB are made of polyester or acrylic material and do provide a safe alternative to sublaminar Luque-type wires (stainless steel) as well as an increased contact area between SB and bone allowing higher corrective forces and reduced laminar fracture risk; the use of SB is not associated with increased risk of neurological injury nor with an increased risk of deep postoperative infection.

Biomechanical and Clinical Comparative Study of the New Elastic Stable Intramedullary Nailing "MJ-FLEX Orthofix".

J Pediatr Orthop 2020 Mar;40(3):149-155

Department of Orthopaedic Pediatric Surgery of Dijon, Hospital François Mitter, Medical University of Dijon, Dijon.

Background: The objectives of this study were first to compare the results of osteosynthesis with standard Metaizeau (MS) nails versus Metaizeau Junior Flex or MJF Orthofix (MJF) in terms of the stability of long-bone fractures in children, and to study the preoperative and postoperative safety of these new nails. We also carried out an analysis by computer modeling of a femur, in order to compare the biomechanical stability of the 2 nails. The interest in the MJF nails lies in the improvements they bring in terms of stability for long-bone fractures in pediatric patients, as well as the simplification of the surgical procedure.

The Effects of Frontal Trauma on 4 Interforaminal Dental Implants: A 3-Dimensional Finite Element Analysis Comparing Splinted and Unsplinted Implant Configurations.

J Oral Maxillofac Surg 2020 Jun 24;78(6):961-972. Epub 2019 Dec 24.

Professor, Head of NumBioLab, Department of Orthodontics, Ludwig Maximilian University of Munich, Munich, Germany.

Purpose: With increased implant-prosthodontic rehabilitation for mandibular edentulism together with the increased life expectancy and activity of the elderly population, a greater number of implant patients may be at risk of facial trauma. The aim of this 3-dimensional (3D) finite element analysis (FEA) was to evaluate the biomechanical effects of the edentulous mandible (EM) with and without implants exposed to frontal facial trauma including assessment of the fracture risk of different mandibular areas.

Materials And Methods: By use of a 3D FEA, our experimental study design comprised 3 different models (model A, EM; model B, EM with 4 unsplinted interforaminal implants; and model C, EM with 4 splinted interforaminal implants) exposed to application of symphyseal frontal trauma of 2 MPa.

Unilateral Cranialization as an Approach for Posterior Table Frontal Sinus Fractures.

J Craniofac Surg 2020 May/Jun;31(3):794-795

School of Medicine, University of Virginia, Charlottesville, VA.

Management of posterior table fractures has seen a conservative shift in recent years. Patients who present with CSF leak may be safely monitored, while cranialization is reserved for patients with severe comminuted or displaced posterior table fractures. We report the case of a 20-year-old patient with a comminuted, displaced posterior table fracture that was missing a central segment and was associated with dural injury. Read More

Single-leg hop mechanics are correlated with self-reported knee function early after anterior cruciate ligament reconstruction.

Clin Biomech (Bristol, Avon) 2020 Mar 24;73:35-45. Epub 2019 Dec 24.

Sports Medicine Research Institute, The Ohio State University Wexner Medical Center, Columbus, OH, United States; Division of Physical Therapy, The Ohio State University, Columbus, OH, United States.

Background: Biomechanical changes that persist after anterior cruciate ligament (ACL) injury may impact short- and long-term outcomes. Understanding the relationship of biomechanics during a dynamic task and patient reported function can better identify patients who are most vulnerable to sub-optimal long-term outcomes, such as osteoarthritis (OA). The purpose of this study was to determine whether hip and knee biomechanics during single-leg hop landing were significantly correlated with the Knee injury and Osteoarthritis Outcome Score (KOOS), and whether symptomatic knees displayed altered biomechanics relative to asymptomatic knees.

Bone Cements in Depressed Frontal Bone Fractures.

Ann Maxillofac Surg 2019 Jul-Dec;9(2):407-410

Department of Oral and Maxillofacial Surgery, Chettinad Dental College and Research Institute, Kancheepuram, Tamil Nadu, India.

Skull fractures can be classified into four major types; linear, depressed, diastatic, and basilar. Of these, a depressed skull fracture presents a high risk of increased intracranial pressure or hemorrhage to the brain. A compound depressed skull fracture results when a laceration over the fracture exposes the internal cranial cavity to the outside environment. Read More
