1. Range and distribution of motion at L5-S1, L4-5, and L3-4 levels for normal (data from literature), untreated (adjacent to treated levels), implanted with a mobile-core prosthesis, and implanted with a fixed-core prosthesis levels.
Range and distribution of motion at L5-S1, L4-5, and L3-4 levels for normal (data from literature), untreated (adjacent to treated levels), implanted with a mobile-core prosthesis, and implanted with a fixed-core prosthesis levels. For untreated levels and implanted levels with a mobile-core prosthesis, the range of motion in flexion and in extension (lightest gray area) are differentiated.
