Understanding low back morphology is critical to understanding spinal loading and the underlying injury mechanisms, which helps to characterize risk and, therefore, minimize low back pain injuries. Individualized erector spinae muscle (ESM) cross-sectional area (CSA) allows biomechanics practitioners to calculate individualized force-generating capacities and spinal loadings for given tasks. The objective is to perform morphological analyses and then provide regression models to estimate the ESM CSA of an individual with his/her subject characteristics. Read More

Ankle sprains are the most common lower extremity injuries associated with sports activity. Although ligament repair techniques are popular, reconstruction methods using free tendons are considered when the ligament remnant is insufficiently strong, when high-demand athletes sustain repeat ankle sprains, or in revision cases after repair. Recently, some arthroscopic reconstruction techniques have been reported. Read More

Soft tissue dysfunction can result from the degeneration of tissues as in the case of degenerative tendinopathy or from the build-up of problematic scar tissue, which can be the result of several aggravating factors, including overuse injuries, acute or chronic trauma, or as a result of surgery. This dysfunction often results in impaired movement, pain, and swelling of the affected area, which can lead to patient dissatisfaction and a lower quality of life. These soft tissue dysfunctions also have a marked economic impact. Read More

Radiologists should be familiar with basic principles of fracture fixation and the normal imaging appearances of implant constructs and their complications. The surgeon's selection of external fixation, intramedullary nail fixation, open reduction and internal fixation, or some combination depends on patient factors, fracture configuration, injury to the soft tissue envelope, and surgeon experience. Complications including loss of fixation with resultant malalignment, nonunion, infection, and posttraumatic osteoarthritis present additional challenges for the surgeon as well as the radiologist.

Background: The lateral ankle ligament complex consisting of the anterior talofibular ligament (ATFL), the calcaneofibular ligament (CFL) and the posterior talofibular ligament (PTFL) is known to provide stability against ankle joint inversion. As injuries of the ankle joint have been reported at a wide range of plantarflexion/dorsiflexion angles, the aim of the present study was to evaluate the stabilizing function of these ligaments depending on the sagittal plane positioning of the ankle joint.

Methods: Eight fresh-frozen specimens were tested on a custom-built ankle deflection tester allowing the application of inversion torques in various plantarflexion/dorsiflexion positions. Read More

Introduction Lateral ankle sprain caused by forcible plantar flexion and inversion of the foot commonly damages the anterior talofibular ligament and other ligaments. Unfortunately, involvement of the bifurcate ligament (BL) is often overlooked when assessing such injuries in clinical practice and identification of this ligament on magnetic resonance (MR) scans can be challenging. Anatomically, the BL is a Y-shaped structure with two bands: the calcaneonavicular ligament (CNL) and calcaneocuboid ligament (CCL). Read More
