Secondary Spinal Cord Injury llI: Pathophysiology

Secondary Spinal Cord Injury llI: Pathophysiology

Early Ischemia and Ionic ImbalanceWithin minutes of spinal cord injury, a secondary cascade begins, progressing over hours to weeks. Vascular damage reduces blood flow, causing ischemia and mitochondrial dysfunction. ATP depletion leads to ion pump failure, membrane depolarization, sodium influx, potassium efflux, and water accumulation, resulting in cellular swelling. Increased intracellular calcium further disrupts mitochondria and accelerates cellular injury.Excitotoxicity and Neuronal...

Summary

This summary is machine-generated.

The Morel-Lavallee lesion (MLL) is a rare closed degloving injury. Early recognition and awareness of MLL presentations are crucial for accurate diagnosis and appropriate treatment selection.

Background:

Morel-Lavallee lesion (MLL) is a rare injury resulting from closed degloving.
It involves the separation of subcutaneous tissue from the underlying fascia, creating a cystic cavity.
MLLs can occur in various body locations, not just the classic trochanteric region.

Purpose of the Study:

To enhance clinician familiarity with Morel-Lavallee lesions.
To reduce missed and incorrect diagnoses of MLL.
To guide appropriate treatment strategies for MLL.

Main Methods:

Literature search of PubMed and EMBASE (1966-2013).
Inclusion of English and Chinese language articles and their references.
Keywords included Morel-Lavallee lesion, closed degloving injury, and related terms.

Main Results:

MLL is a rare closed degloving injury characterized by subcutaneous tissue and fascial separation.
The natural history of MLL is variable, with potential for spontaneous resolution, stability, enlargement, or recurrence.
Diagnostic imaging (ultrasound, CT, MRI) is valuable; diagnosis is often delayed.
Treatment options include compression, aspiration, debridement, and sclerodesis, with no established standard.

Conclusions:

Suspect MLL in cases of fluctuant skin areas or recurrent fluid collections after shear injury.
Awareness of both acute and chronic MLL appearances is vital for correct diagnosis by clinicians and radiologists.
Treatment should be individualized based on fracture association, lesion condition, symptoms, and patient preference.
