A novel technique to create a reproducible in vivo model of cervical spinal cord laceration injury in the mouse is described. This technique is based on spine stabilization by fixation of the cervical facets and laceration of the spinal cord using an oscillating blade with an accuracy of ±0.01 mm.

Athletes absorb several hundred mild traumatic brain injuries (mTBI)/concussions every year; however, the consequence of these on the brain is poorly understood. Therefore, an animal model of single and repetitive mTBI that consistently replicates clinically relevant symptoms provides the means to advance the study of mTBI and concussion.

Training a person with paralysis to ambulate using a powered exoskeleton may present challenges. The goals are to present the candidate selection criteria and the training procedures for exoskeletal-assisted walking and other mobility skills that can be progressed as the participant's skill level improves.

Lateral fluid percussion (LFP), an established model of traumatic brain injury in mice, is demonstrated. LFP fulfills three major criteria for animal models: validity, reliability and clinical relevance. The procedure, consisting of surgical craniotomy, fixation of hub followed by induction of injury, resulting in focal and diffuse injuries, is described.

Ischemia-reperfusion Model of Acute Kidney Injury and Post Injury Fibrosis in Mice

We describe models of moderate and severe ischemia-reperfusion-induced kidney injury in which the mice undergo unilateral renal pedicle clamping followed by simultaneous or delayed contralateral nephrectomy, respectively. These models consistently give rise to renal dysfunction and post-injury fibrosis, but injury severity and survival are dependent on mouse background, age and surgical equipment.
FAQs
A labrum injury may develop after a single traumatic event, such as a dislocation, or after repeated mechanical stress. Repetitive overhead motion can affect the shoulder, while forceful hip rotation can stress the hip joint. These different loading patterns help explain why clinicians consider both the activity history and the specific joint involved.
Damage to the stabilizing fibrocartilage can reduce how securely the ball-and-socket joint functions during movement. That loss of stability may be accompanied by pain, clicking, or catching, while some patients develop limited motion. The combination and severity of these symptoms provide clinical clues about how the injury is affecting joint function.
Symptoms alone may not identify labral damage because pain and restricted movement can occur with other joint conditions. Clinicians therefore combine the injury history with a physical examination and imaging. This process helps distinguish a labral tear from alternative explanations and connects the suspected tissue damage with changes in stability or movement.
Evaluation begins with the circumstances of the injury and the symptoms that followed. A physical examination then assesses the joint’s clinical presentation, while magnetic resonance imaging may provide additional information about the labrum. Using these sources together supports a more informed distinction between labral damage and other joint conditions.
Magnetic resonance imaging is used as part of the assessment when clinicians need imaging information about suspected labral damage. It does not replace the injury history or physical examination; instead, it contributes another type of evidence. The combined evaluation can help clarify whether symptoms and functional changes are consistent with a labral tear.
Treatment depends on the tear’s location and severity, the symptoms it produces, and its effect on joint function. Initial management may include activity modification and physical therapy. When the injury continues to impair function or requires a procedural approach, arthroscopic repair may be considered as part of the treatment plan.
