Percutaneous endoscopic decompression for calcified thoracic disc herniation using a novel T rigid bendable burr.

BACKGROUND: The basic endoscopic instruments are not suitable for removing calcified or hard discs in patients with thoracic disc herniations (TDH). We describe a percutaneous endoscopic technique for the treatment of calcified TDH using an endoscopic drill system with a T rigid bendable burr. METHODS: Eleven patients (8 males, mean age 42.1 years) with single-segmental calcified TDH were treated with percutaneous endoscopic surgeries. RESULTS: Our technique using this endoscopic drill system with a T rigid bendable burr is safe and effective for the treatment of calcified TDH. CONCLUSIONS: Percutaneous endoscopic decompression using the T rigid bendable burr is a safe and reproducible surgical procedure for the treatment of calcified TDH.
