What is Lumbopelvic fixation?
Lumbopelvic fixation is an essential treatment modality for U-type variant sacral fracture patterns that create spinopelvic instability. It can also augment IS screw fixation for complex pelvic ring fractures without spinopelvic instability.
What is sacral fixation?
Sacroiliac screw fixation is a commonly used procedure for iliosacral joint fracture-dislocations and sacral fractures. Currently, the standard technique is the percutaneous iliosacral screw fixation under conventional C-arm fluoroscopy that often exposes the patient to prolonged radiation.
What is Spinal dissociation?
Spinopelvic dissociation is a transverse fracture of the sacrum with a longitudinal transforaminal bilateral fracture, which causes a dislocation of the spine and the upper body of the sacrum from the pelvis and the sacral wings [2].
What is triangular osteosynthesis?
Triangular osteosynthesis is a subcategory of spinopelvic fixation. It combines. lumbopelvic fixation ((usually unilateral) from the pedicle of L5 to the ipsilateral posterior ilium, and. transverse sacral alar fracture fixation (iliosacral screw/s, sacral plate, etc.)
What is s4 fracture?
A sacral fracture occurs when a bone called the sacrum breaks. The sacrum is a large triangular bone at the bottom of the spine. It fits like a wedge between the two hip bones. The sacrum is made up of the sacral vertebrae, which are fused together. Sometimes the coccyx, or tailbone, is fractured along with the sacrum.
What type of fracture is sacral ala?
Zone-I fractures mainly involve the sacral ala, with possible extension into the sacroiliac joint. The fractures can be subdivided into stable and unstable injuries, according to the three-stage severity system. Neurological injury occurs in approximately 6% of patients and typically involves the L4 and L5 nerve roots.
What is Lumbopelvic dissociation?
Lumbopelvic dissociation is defined as your ability to move your hips and your lumbar spine independently from each other – it is often lacking in people who have chronic low back pain.
What is a cape like sensation?
In the early stages, a sense of touch is still present. A loss of feeling may spread over the shoulders and back, described as a “cape-like” distribution. Affected individuals may also develop pain and stiffness (spasticity) in the legs and uncoordinated movements (ataxia), eventually affecting the ability to walk.
What is Malunion?
A malunion occurs when a fractured bone heals in an abnormal position, which can lead to impaired function of the bone or limb and make it look like it is ‘bent’. Similarly, a nonunion is the result of a fractured bone failing to heal after an extended period of time – in some cases over a period of 9 to 12 months.
What is an S2 fracture?
A sacral fracture occurs when a bone called the sacrum breaks. The sacrum is a large triangular bone at the bottom of the spine. It fits like a wedge between the two hip bones.
Why is Lumbopelvic dissociation important?
BACKGROUND CONTEXT: Lumbopelvic dissociation (U/H shaped sacral fracture) can be devastating injuries with a high incidence of concomitant spine and pelvis fractures and neurological injuries.
What is the difference between malunion and nonunion?
Where is S2 in the spine?
S2. S2 is located at the level of posterior superior iliac spine. S2 covers the back of the thighs.
