Description
Removing a slipped lumbar disc through tiny portals leaves a torn ring behind, and Jiale Liu and co-authors asked whether stitching that ring shut changes the first year's outcome. They compared 62 patients at one hospital: 30 whose disc removal was followed by suturing of the annulus fibrosus, the disc's tough outer ring, and 32 with removal alone. Both groups hurt less and functioned better after surgery. The stitched group reported less leg pain three days out, though surgery took longer.
At one year, disc height had shrunk about 9 percent in the stitched group and 10 percent in the other. Two recurrences and two cases of worsening degeneration appeared, all in the unsutured group. The authors read the early results as promising but preliminary.
