Nonoperative Management of Isolated Thoracolumbar Flexion Distraction Injuries: A Single-Center Study.
Int J Spine Surg
September 2024
Department of Orthopedic Surgery, University of Alabama at Birmingham, Birmingham, Alabama, USA
Background: Nonoperative management is an appealing option for purely transosseous thoracolumbar flexion-distraction injuries given the prospects of osseous healing and restoration of the posterior tension band complex. This study seeks to examine differences in outcomes following flexion-distraction injuries after operative and nonoperative management.
Methods: This study reviews all patients at a single Level 1 trauma center from 2004 to 2022 with AO Spine B1 thoracolumbar injuries treated operatively vs nonoperatively.
An ovine knee simulator: description and proof of concept.
Front Bioeng Biotechnol
June 2024
Biomechanics Group, Mechanical Engineering Department, Imperial College London, London, United Kingdom.
Aims: The ovine stifle is an established model for evaluation of knee treatments, such as meniscus replacement. This study introduces a novel ovine gait simulator for pre-testing of surgical treatments prior to animal trials. Furthermore, we describe a pilot study that assessed gait kinematics and contact pressures of native ovine stifle joints and those implanted with a novel fiber-matrix reinforced polyvinyl alcohol-polyethylene glycol (PVA-PEG) hydrogel meniscus to illustrate the efficacy of the simulator.

Department of Pediatrician Surgery, Non-Profit Joint Stock Company Astana Medical University, Astana, Kazakhstan.
Background: Transosseous distraction osteosynthesis is prioritized in orthopedic care for children with achondroplasia. However, difficulties encountered during treatment and rehabilitation directly impact patients' quality of life. Using rod external fixators within a semicircular frame for osteosynthesis is less traumatic compared to spoke circular devices.

November 2023
Department of Mechanical Engineering, Sejong University, Seoul 05006, Republic of Korea.
There are many techniques for the treatment of chronic scapholunate dissociation. The three-ligament tenodesis (3LT) is used most widely, but reconstruction of the dorsal ligament alone may not provide sufficient stability. The Mark-Henry technique (MHT) compensates for the insufficient stability of 3LT by additional reconstruction of the volar ligament, but the procedure is complex.

Hand (N Y)
June 2023
Kantonsspital St. Gallen, Switzerland.
Background: Multiple techniques for the repair of flexor tendon injuries in zone 1 have been proposed over time. While pull-out suture techniques and bone anchor seem to be stronger than internal suture techniques, they are associated with a higher complication rate. We therefore developed an alternative internal suture repair with similar biomechanical stability to those of pull-out sutures and bone anchors.
