Summary
A large lateral meniscal cyst caused irreversible foot drop in a rare case. This study discusses the presentation, management, and uncommon causes of foot drop.
Area of Science:
- Orthopedics
- Neurology
Background:
- Foot drop is a common neurological symptom with various causes.
- Meniscal cysts are typically associated with knee joint pain and mechanical symptoms.
Observation:
- An unusual case of irreversible foot drop was observed.
- The foot drop was secondary to a large lateral meniscal cyst.
Findings:
- A large lateral meniscal cyst can present as a rare cause of foot drop.
- This case highlights the importance of considering uncommon etiologies for foot drop.
Implications:
- This case expands the differential diagnosis for foot drop.
- Early recognition and management of meniscal cysts may prevent irreversible neurological deficits.

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...
Bones of the Lower Limb: Femur and Patella
The femur is the body's longest and strongest bone spanning the thigh region. Its head articulates with the acetabulum of the hip bone to form the hip joint. A minor indentation on the medial side of the femoral head, called the fovea capitis, serves as the site of attachment for the ligament of the head of the femur. This weak ligament spans the femur and acetabulum and supports the hip joint. The narrowed region below the head is the neck of the femur. The inclination angle between the neck...
