L4-L5 & L5-S1 partial Dissectomy done ;In 2nd stage in prone, after 7 days ,residual pedicles, discs & complete neural arch of L5 removed; L4 & S1partial laminectomy done, L4-L5-S1& sacral nerve roots decompression done , and the body of L4 was reduced onto S1with pedicle screw fix...
Entrapment of the \{L5\} nerve root by anterior osteophytes at the L5-S1 junction is rarely reported. Posterior decompression of the \{L5\} nerve root is commonly performed, but anterior decompression of the \{L5\} nerve root is not a frequently performed procedure. The purpose of this ...
