Multilevel spine degeneration with deformity should be described in 3 column theory of lumbar degenerative cascade to detect completely the degenerative damage or deformator
Theory of degenerative spine deformity is a combination between 2 factors :
- spine stabilizer ( disc, 2 facet joints, anterior and posterior longitudinal ligament, supraspinatus ligament and multifidus muscle )
- spine deformator ( degenerative damage )
Gold standard is open surgery to remove deformator, but this will sacrifice the stabilizer, then need an artificial stabilizer or fusion
Concept of Minimally invasive Endoscopic spine surgery is removing the deformator only, while still preserving the stabilizer, then no fusion is needed
After removing deformator, the stabilizer will be refunctioned again and deformity is corrected naturally
