Dissociative Disorders01:27

Dissociative Disorders

1.1K
Dissociative disorders represent complex psychological conditions characterized by disruptions in consciousness, memory, identity, or perception. These disruptions cause individuals to experience a disconnection from their thoughts, emotions, and memories. The phenomenon is not merely an occasional lapse in attention but a profound alteration in mental functioning that can severely impact daily life.

Dissociative Identity Disorder01:30

Dissociative Identity Disorder

2.4K
Dissociative Identity Disorder (DID), previously termed multiple personality disorder, is a complex psychological condition characterized by the presence of two or more distinct identities or personality states. Each identity exhibits unique patterns of behavior, voice, and mannerisms and may possess separate memories and emotional responses. The alternating control between identities can result in memory gaps and challenges in recalling daily activities, often exacerbating the individual's...

Overview of the Axial Skeleton01:09

Overview of the Axial Skeleton

11.8K
The skeleton is subdivided into two major divisions—the axial skeleton and the appendicular skeleton. The axial skeleton forms the vertical, central axis of the body. It includes all of the bones of the head, neck, chest, and back. It protects the brain, spinal cord, heart, and lungs. It also serves as the attachment site for muscles that move the head, neck, and back and for muscles that act across the shoulder and hip joints to move their corresponding limbs.
The axial skeleton of the...

Functional Classification of Joints01:09

Functional Classification of Joints

8.1K
Functional Classification of Joints
The functional classification of joints is determined by the amount of mobility between the adjacent bones. Joints are functionally classified as a synarthrosis or immobile joint, an amphiarthrosis or slightly moveable joint, or as a diarthrosis, a freely moveable joint. Fibrous and cartilaginous joints can be functionally classified as either synarthroses  or amphiarthroses, whereas all synovial joints are classified as diarthroses.

Articulations of the Vertebral Column01:28

Articulations of the Vertebral Column

3.5K
In addition to being held together by the intervertebral discs, adjacent vertebrae also articulate with each other at synovial joints formed between the superior and inferior articular processes called zygapophysial joints (facet joints). These are plane joints that provide for only limited motions between the vertebrae. The orientation of the articular processes at these joints varies in different regions of the vertebral column and serves to determine the types of motions available in each...

Spinal Nerves: Plexus II01:21

Spinal Nerves: Plexus II

3.1K
The plexuses of the lower body include the lumbar, sacral, and coccygeal plexuses, which innervate the abdomen, pelvis, legs, and coccygeal region. These plexuses control the transmission of sensory information and coordinate motor functions of the lower body.
The Lumbar Plexus
The lumbar plexus is situated within the lumbar region of the back and is primarily formed by the first four lumbar spinal nerves (L1 to L4). This plexus extends its branches into several nerves, including the...

Summary
This summary is machine-generated.

Spondylopelvic dissociation, known as "suicide jumper's fractures," involves severe lumbopelvic instability. Treatment focuses on stabilizing bilateral sacral fractures using methods like triangular osteosynthesis.

Area of Science:

  • Orthopedic Surgery
  • Trauma Surgery
  • Spinal Biomechanics

Background:

  • Spondylopelvic dissociation is a severe injury causing multiplanar lumbopelvic instability.
  • Historically termed "suicide jumper's fractures," these injuries are increasingly seen due to military conflicts.
  • Characterized by bilateral vertical sacral fractures with a horizontal component, leading to lumbosacral instability.

Purpose of the Study:

  • To review the characteristics and management of spondylopelvic dissociation.
  • To highlight the evolving surgical treatment options for this complex injury pattern.

Main Methods:

  • Review of literature on spondylopelvic dissociation.
  • Analysis of surgical techniques, including percutaneous and open approaches.
  • Focus on triangular osteosynthesis as a primary fixation method.

Main Results:

  • Spondylopelvic dissociation results in significant sagittal and axial instability.
  • Surgical interventions aim to restore stability and facilitate bone healing.
  • Triangular osteosynthesis is a commonly employed and effective fixation strategy.

Conclusions:

  • Spondylopelvic dissociation is a complex, high-energy injury requiring specialized orthopedic management.
  • Advances in surgical techniques offer improved outcomes for patients with this condition.
  • Effective fixation, such as triangular osteosynthesis, is crucial for successful treatment.
